Indigenous nations fought for a new national monument. Will it survive Trump?
- After decades of activism by the Ajumawi–Atsugewi Nation (Pit River Nation) to protect its ancestral homelands from extractive industries, vandalism and looting, President Joe Biden created Sáttítla Highlands National Monument in northern California in 2025.
- Sáttítla’s management plan supports co-stewardship by Indigenous nations with connections to the landscape.
- The Trump administration has sown confusion over Sáttítla’s fate by releasing and then deleting documents and proclamations online that said the monument would be rescinded.
New research finds substantial peat deposits in Colombia’s conflicted Amazon
- A new study of Colombia’s lowland forests and savannas finds that the nation may have extensive peatlands — organic wetland soils formed over thousands of years — holding as much as 70 years’ worth of Colombia’s carbon emissions. Protecting them from agricultural development is essential to preventing greenhouse gas releases.
- Researchers made peatland estimates by taking sediment cores in 100 wetlands, quantifying peat content, then building a model to predict locales for other peat-forming wetlands using satellite imaging. Peat was found in unexpected ecosystems, such as nutrient-poor white-sand forests, widespread in northern South America.
- Sampling in many locations was only possible due to the ongoing but fragile peace process between the Colombian government and armed rebel groups. In some places, security has already deteriorated and further sampling is unsafe, making this study’s scientific estimate a unique snapshot for now.
- Most Colombian peatlands are remote, but deforestation is intensifying along the base of the Andes, putting some wetlands at risk. Colombia’s existing REDD+ projects have been controversial, but opportunities may exist to combine payments for ecosystem services with peacebuilding if governance and security can be improved.
How Mexican fishers are protecting an endemic oyster — and its ecosystem
- In Mexico’s Nayarit marshes on the Pacific Coast, the work of a fishing group called Ostricamichin has enabled the recovery of the Cortez oyster, an endemic and economically important mollusk, along with other marine species.
- The Marismas Nacionales Nayarit National Reserve, where the Cortez oyster is cultivated, accounts for 45% of Mexico’s national fishing production, thanks to floating rafts that help grow the endemic species in its waters.
- However, members of Ostricamichin say their project is threatened by climate change and illegal fishing. But the biggest threat, currently, is a proposed dam project which, they say, would devastate the delicate ecosystem.
Diverse forests and forest rewilding offer resilience against climate change
- Recent studies from two long-running planted forest experiments in China and Panama find that increasing tree diversity in reforestation efforts can boost resilience in the face of climate change, among other benefits.
- Researchers elsewhere propose a “rewilding-inspired forestry” approach that aims to restore biodiversity, aid climate mitigation and bolster forest ecosystems — an approach that requires a significant shift from current forestry practices.
- However, scientists underline that while reforestation and forest rewilding can contribute to curbing climate change, they have their limits and must be combined with deep carbon emissions cuts and conservation of existing forests.
How is conservation preparing for a much hotter world? Experts share
- Fifty years from now, in 2075, the world will be considerably hotter, perhaps as much as 3-5° Celsius (4.5 to 9° Fahrenheit) above the pre-industrial average.
- Experts say we need to focus on building greater resilience into ecosystems now to help species get through the next half century.
- We should be protecting large landscapes, including altitudinal gradients, according to experts.
- We should also be focusing on good management, community relations, rewilding and restoration.
Dugong numbers plummet amid seagrass decline in Thailand’s Andaman Sea
- Thailand’s dugongs are disappearing fast, reflecting an unfolding crisis in the region’s seagrass ecosystems.
- Seagrass beds on Thailand’s Andaman Sea coast that support one of the world’s most significant populations of dugongs have died off in recent years, creating an increasingly challenging environment for the charismatic marine mammals.
- Scientists point to a combination unsustainable coastal practices and climate change as the main factors driving the decline.
- Government agencies, marine scientists and volunteers are taking emergency steps to save the remaining dugongs, but experts warn their long-term survival in Thailand depends on fixing the root causes of the seagrass loss.
Betting on future forest carbon storage endangers Paris Agreement targets
- The carbon storage capacity of forests is widely recognized as a crucial factor in curbing global warming and preventing climate catastrophe.
- But a new study finds that the future potential for forest CO2 storage is being overestimated, with global forest health (along with the ability of forests to go on storing carbon) vulnerable to increasing disturbances including wildfires, disease, pests and deforestation.
- Scientists argue that the very real threat of declining forest carbon storage capacity necessitates far faster decarbonization efforts, along with urgent action to monitor and conserve forests, and prevent widespread deforestation.
- Delaying action by as little as five years could incur huge economic costs and jeopardize climate goals, researchers found.
New strategy launched to protect Tanzanian biodiversity hotspot
- A conservation strategy for the next 20 years has been launched to protect Tanzania’s most biologically rich landscape.
- The Udzungwa Mountains are home to rare and endemic plants and animals, including a small population of kipunjis, a genus of monkeys only revealed to the world in 2006.
- Sustainable financing is being sought to fund the conservation strategy and boost livelihoods and social well-being in communities surrounding three core protected areas.
- A key part of the strategy will be the rollout of energy-efficient stoves, seen as a priority by local communities who depend on firewood and charcoal.
Kenya’s cities adopt Miyawaki method to restore lost ecological glory
- Due to urbanization and human settlements destroying natural forests, African cities are increasingly experiencing high traffic noise, harmful emissions, and a “concrete jungle” development.
- In Kenya’s capital city, Nairobi, forest cover decreased from 14% in 1976 to 3.3% in 2000. The city’s natural vegetation, too, decreased from 15% in 1979 to 2.7% in 2000.
- Since 2007, a restoration practice known as the Miyawaki method has successfully established mini forests in three areas in the capital, Nairobi, planting over 236,212 seedlings between 2011 and 2020.
- The project has benefited local communities by providing tree seedlings and forest maintenance activities; one resident has provided over 30,000 seedlings to the reforestation company and is currently working on their projects.
Beyond reforestation, let’s try ‘proforestation’
- “Proforestation” describes the process of allowing existing forests to continue growing without human interference as they achieve their full ecological potential for carbon sequestration and biodiversity.
- Old forests sequester a higher amount of carbon than younger ones, with large, old trees containing the most carbon.
- Many species are old forest specialists, relying on ancient forests for survival. Losing these forests may mean their extinction.
Climate change spikes wildfire risk in Sri Lanka
- Almost all forest fire in Sri Lanka is human-caused; the two main forest fire seasons are February to March and July to August.
- Annually, 100-2,500 hectares (247-6,178 acres) of forest resources are damaged due to forest fires in Sri Lanka, and in the past few years, the damage to forest resources by fire has increased and is likely to continue increasing with global warming.
- Usually, wildfires are mainly occurring in forest plantations or grasslands where they do not spread to dense forest, but as of late, fires have begun to reach forest areas.
- Some ecosystems like savanna need fire to sustain them, as seeds in some of the trees need fire to crack their outer layer in order to germinate. But in areas with invasive guinea grass, which burns longer and hotter, large trees are also observed dying.
Bleak future for Karoo succulents as desert expands in South Africa
- Recent population surveys show continued decline in two desert-adapted succulent tree aloe species, with conservationists fearing for the state of an understudied third species.
- A years-long drought has accelerated spreading dust-bowl conditions following decades of mining and heavy grazing, with grave consequences for endemic succulents.
- A conservation triage should prioritize cultivating at-risk species in nurseries and botanical gardens, many of which are unlikely to survive reintroduction into their natural habitats.
Why are the British flooding parts of their coast?
SOMERSET, England — Steart Marshes, in southwest England, may not be the most picturesque nature reserve in the British Isles, but it is undoubtedly one of the most fascinating. Just over a decade ago, this landscape was farmland, but its precarious position, wedged between the River Parrett and the Bristol Channel, made it highly vulnerable […]
Initiative sets sights on rewilding three New Zealand islands
Three New Zealand islands will join an international initiative to remove invasive species and restore native wildlife. With the addition of Maukahuka (Auckland) Island, Rakiura (Stewart) Island and Chatham Island, the Island-Ocean Connection Challenge (IOCC) will have 20 ongoing projects aimed at restoring and rewilding 40 globally significant island-ocean ecosystems by 2030. “New Zealand’s three […]
COP16 biodiversity summit in Rome OKs finance pathway; big obstacles loom
- When the COP16 U.N. biodiversity summit ended without a final agreement in October 2024 in Cali, Colombia, negotiators agreed to meet in Rome, Italy, in February. There, the parties mapped a sweeping permanent plan on how to raise $200 billion annually by 2030 to reverse global species extinctions and conserve life on Earth.
- In Rome, the parties approved mechanisms for raising, tracking and reporting on that huge sum, with funding potentially coming from nations, philanthropies, banks and even corporations. The Achilles’ heel of this agreement is that no funding commitment made by any party now or in the future is legally binding.
- Even as participants celebrated this funding strategy breakthrough, two major powers dealt blows to finance targets. The U.S. under President Donald Trump abandoned USAID conservation financial commitments abroad, while the U.K. announced a shift in priorities away from climate and biodiversity foreign aid to military spending.
- The final Rome agreement also reduced the likelihood that trillions of dollars paid out by the world’s nations in “perverse subsidies” to industries that do the greatest harm to life on Earth would be redirected in a timely way to global biodiversity goals.
India’s Adani withdraws from controversial Sri Lanka wind power project
- A proposed wind power project by Indian billionaire Gautam Adani in the north of Sri Lanka, which ran into strong opposition from environmentalists due to multiple potential ecological impacts, particularly on migratory bird species, has come to halt.
- Five lawsuits were filed against the company by local environmental organizations due to the project’s alleged environmental consequences as well as the contract being awarded without competitive bidding.
- Amid growing controversy, Adani Green Energy Ltd. withdrew from the proposed project on Feb. 12 claiming “financial nonviability” weeks after the new Sri Lankan government sought to renegotiate the agreement and formed a committee to review and renegotiate the power purchase rate.
- Mannar, a district rich in wildlife and known for its picturesque quality, is currently experiencing a surge in nature-based tourism, particularly due to its rich birdlife.
Pangolin burrows are biodiversity magnets in burnt forests, study shows
- As insectivorous, burrowing mammals, pangolins play a key role in our ecosystem by controlling insect populations, recycling soil nutrients and sheltering other animals in their abandoned burrows.
- A recent study provides the first evidence of Chinese pangolins’ role as ecosystem engineers, whose burrows help restore biodiversity in forest patches gutted by fires.
- Over a two-year period, the study found that areas with pangolin burrows had more plant and animal species richness and diversity compared to sites without burrows, proving that pangolins accelerate ecosystem recovery.
- Experts say the study’s findings serve as another reason to conserve the scaly mammals and reintroduce them back into the wild.
Only 17% of peatlands, vital to curbing climate change, are protected, study finds
- Just 17% of peatlands worldwide are protected, according to a new study, despite the fact that they hold more carbon than all the world’s forests.
- Peatlands are waterlogged accumulations of dead, partly decomposed vegetation, and are scattered widely from the northern latitudes through temperate zones to the equatorial tropics.
- The new maps show that more than 25% of peatlands overlap with Indigenous territories, an area of some 1.1 million square kilometers (about 425,000 square miles); much of that land doesn’t overlap with other forms of protection, providing an opportunity to keep peatlands intact through the strengthening of Indigenous land rights.
- Conservation scientists see targeting peatlands for protection as “low-hanging fruit” to deal with climate change because they’ve stockpiled so much carbon on only about 3% of land on Earth.
Darfur’s women refugees lead reforestation of war-blighted Sudan–Chad borderland
- The Darfur conflict has caused a massive increase in tree cutting for charcoal and firewood, as lack of cooking gas forces families to rely on these resources.
- To mitigate this, in the Adré refugee camp in neighboring Chad, a small organization plants neem trees to restore vegetation, provide shade, and reduce tensions over access to firewood.
- The influx of displaced populations into camps like Adré strains fragile ecosystems: Overcrowding increases pressure on water resources and vegetation, leading to further desertification, soil erosion, and conflict over shared natural resources between refugees and host communities.
- Grassroots and U.N. initiatives, such as reforestation and the promotion of energy-efficient stoves, aim to mitigate the damage, but more funding is needed to scale up these efforts.
The world’s kelp needs help — less than 2% is highly protected
- Kelp forests support a kaleidoscope of biodiversity and perform crucial ecosystem functions, yet they are in trouble globally.
- A recent journal commentary shows that just 15.9% of kelp forests are in protected areas, and only 1.6% of them are in areas with the highest levels of protection.
- The authors said they hope their findings will motivate policymakers to include kelp forests in international conservation targets, such as the “30×30” mandate to protect 30% of Earth’s land and sea by 2030.
In Ecuador, a mountain shrub could hold the key to restoring a precious ecosystem
- The spread of agriculture, including the use of fires to clear native vegetation, have devastated Ecuador’s páramo, a high-altitude ecosystem that represents a critical source of drinking water for local communities.
- Reforestation of frailejones, a rare shrub species that helps trap humidity from the air and filter water to the ground, may prove key to restoring the ecosystem.
- A privately financed initiative in Ecuador is researching how to grow the shrub at scale in a nursery for mass replanting, but faces teething challenges in this first-of-its-kind initiative for the country.
Underwater volcano in Barents Sea reveals diverse marine life, study finds
What’s new: Following the discovery of the underwater Borealis Mud Volcano on the Arctic seabed in 2023, researchers have now confirmed that the methane-spewing volcano is home to a diverse array of marine life thriving in the unique habitat. What the study says: In 2023, scientists from UiT The Arctic University of Norway discovered the […]
Indigenous knowledge helps explain bird population changes in Canada’s BC
- The types of birds that visit and thrive on the islands of Yáláƛi, the Goose Island Archipelago, a Canadian Important Bird Area, have changed dramatically in the past 70 years.
- The Haíɫzaqv people, stewards of the land for millennia, and academics have analyzed ecosystem data and traditional knowledge to uncover the drivers of change.
- The discovery that varying patterns of mammals, human use and natural disasters has reshaped biodiversity on the archipelago offers vital lessons for stewardship elsewhere on Haíɫzaqv territory.
Lures that attract seed-dispersing bats could aid tropical reforestation
- Fruit-eating bats play an important role in maintaining forest health by being seed dispersers. For decades, researchers have explored ways to harness this capacity as a reforestation tool.
- One method has been to use fruit-derived essential oils to attract bats to deforested sites, where their seed-loaded feces may help stimulate regrowth.
- A recently published study goes one step further by using chemical compounds derived from those oils to attract bats. This new way of making lures could prove less expensive, so cheaper to scale up. But before such reforestation tools are widely implemented, more research and evidence are required.
- Long-term testing is needed to show that bat lures, and the seed dispersal they bring, markedly aid regrowth — a complex process that can fail due to seed competition with grasses and seed predation. Some experts say planted tree patches are better attractants; others say combined methods may work best.
In Uganda, a women-led reforestation initiative fights flooding, erosion
- Changing rainfall patterns have led to increasingly frequent flooding in western Uganda’s Kasese district, destroying farmers’ homes and fields.
- The damage is exacerbated by the loss of tree cover, as many trees have been cut down by locals for firewood.
- Janet Nyakairu Abwoli from Kasese organizes workshops to teach women how to plant and care for trees, particularly Dracaena and Ficus species.
- These native species can help prevent erosion of slopes and riverbanks, retain soil moisture, and provide fodder for small livestock and ingredients for traditional medicine.
Scientists are tracking global wildlife’s contributions to humanity
- New research assesses in detail the contributions of wildlife to people.
- Humanity relies on an array of ecosystem services for well-being and survival, but the provision of these services rely not just on vegetation but also the wild animals that inhabit the same ecosystems.
- They found that vertebrate wildlife on land and in freshwater and marine environments support 12 of the 18 categories of nature’s contributions to people set forth by the U.N.’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services.
- The authors say that accounting for wildlife along with measures of ecosystems such as vegetation cover will provide a more complete picture of their health and help guide decision-making aiming to ensure that those ecosystems continue to provide critical services to people.
Vested interests and social tribes in the Pan Amazon
- Local and regional actors, particularly commercial and landowner elites in mid-sized cities, play an important role in the expansion and improvement of road networks. In Brazil, lobbying by private interests played a big role in the development of Rodovia Transamazônica and BR-319.
- In Brazil, agribusinesses exert political power via the Frente Parlamentar da Agropecuária (FPA), often referred to as the Bancada Ruralista, a multi-party congressional voting bloc.
- One of the most significant accomplishment of the ruralistas was their 2012 campaign to modify Brazil’s the Forest Code. Changes included amnesty for property owners who had illegally deforested land before 2008 and adjusted requirements to reforest portions of landholdings that had exceeded legal deforestation limits.
New alert system can track changes in grasslands, farms, temperate forests
A new global data set makes it possible to track near-real-time changes in several types of vegetation across different ecosystems, including grasslands, savannas, shrublands, croplands, temperate forests and boreal forests. Called DIST-ALERT, the new product can be visualized on the Global Forest Watch platform of the World Resource Institute (WRI). GFW has long offered the […]
One atlas to map all ecosystems on Earth: Interview with Yana Gevorgyan
- The Global Ecosystems Atlas is a tool that aims to serve as an open-source repository for data on all the ecosystems in the world.
- Developed by the intergovernmental initiative Group on Earth Observations, the Global Ecosystems Atlas pulls together existing data while also using remote sensing and AI technologies to fill gaps in areas where data don’t exist.
- The proof of concept for the tool was launched at the COP16 biodiversity summit in Cali, Colombia, in November last year.
As lithium mining bleeds Atacama salt flat dry, Indigenous communities hit back
- The Council of Atacameño Peoples filed a complaint in October 2024 against lithium mining companies operating in Chile’s Atacama salt flat, accusing them of causing the land to sink around their extraction wells.
- The complaint was based on findings from a study published in July that revealed portions of the salt flat are subsiding by up to 2 centimeters, or nearly an inch, per year.
- Scientists warn that one of the main consequences could be the loss of the aquifer’s storage capacity.
- They also point out that since the salt flat lies on a tectonic fault, the subsidence could spread further, including to two protected areas in the region that are home to flamingos and other rare wildlife.
Communities warn of threat to ecosystems from Brazil bridge project
- Islanders and experts have warned of widespread environmental and social impacts from the construction of a bridge linking the Brazilian city of Salvador with the island of Itaparica in Todos os Santos Bay.
- Critics say the project will devastate mangrove forests and coral reefs, leading to environmental imbalance, compromising fishing communities and threatening the survival of many marine species including humpback whales and sea turtles.
- Proponents say the bridge will boost development in the region, in particular transporting agricultural produce, but islanders say the anticipated population surge on Itaparica will create unsustainable pressure on public services as well as drastically change the dynamics of the community living there.
- Experts say the best solution for improving transportation links between Salvador and Itaparica is to invest in the existing ferry system, but this option wasn’t considered by planners.
In Chile, discovery of shallowest red hydrocoral forest yet surprises scientists
- Scientists have discovered massive marine forests in southern Chile’s Kawésqar National Reserve, formed by the red hydrocoral species Errina antarctica.
- These colonies, found at depths ranging from 1.23 to 33 meters (4 to 108 feet), are the world’s southernmost and shallowest known to date.
- Experts emphasize the importance of protecting these fragile ecosystems and hope the newly discovered forests will be considered in the reserve’s management plan.
Experts welcome Brazil’s revived reforestation plan as much-needed boost
- By 2030, Brazil aims to restore 12 million hectares (30 million acres) of degraded land through the Planaveg initiative, revised and launched by the government at the recent COP16 biodiversity summit in Cali, Colombia.
- Experts have welcomed the move amid growing international commitments to protect biodiversity and stabilize the climate, but point to challenges such as securing resources and social mobilization.
- As ambitious as the target is, it still falls short of the 20.7 million hectares (51.2 million acres) of native vegetation that have been illegally degraded just on private rural plots.
Report reveals how environmental crime profits in the Amazon are laundered
- A recent report from the FACT Coalition analyzed 230 cases of environmental crime in Amazon countries over the past decade to better understand how crimes are committed and how the associated profits are laundered.
- It found that the U.S. is the most common foreign destination for the products and proceeds of environmental crimes committed in the Amazon region.
- The most popular way to launder money involves the use of shell and front companies, and corruption was the single most prevalent convergent crime mentioned.
- Of the cases analyzed, only one in three appears to have included a parallel financial investigation.
Defending the hidden forest gems of Zambia’s Copperbelt Province
- A local community has taken over protecting and managing patches of small evergreen forests, known as mushitu forests, that have recently been subject to illegal logging.
- Forest officers armed with smartphones are going up against the loggers while also enforcing community-driven prohibitions against overuse by locals.
- During times of severe drought, like this year, the forest is a lifeline to villages within the Ndubeni Chiefdom, whose members depend on it not just for water, but for food and medicine.
- The forest has enormous cultural and historical significance, and protecting it is key to protecting the community’s cultural history.
Satellite firm Planet’s ‘biodiversity subscription’ aims to make tech accessible
- A new initiative by Earth-imaging company Planet gives conservation organizations in biodiversity hotspots access to high-resolution, high-frequency satellite data.
- As part of Project Centinela, eight entities have received access to satellite data and analysis tools to help them track and monitor biodiversity in places including Bolivia, Costa Rica, Indonesia and the Democratic Republic of Congo.
- The organizations will have access to the data for three years as part of what Planet calls a “biodiversity subscription.”
- Planet aims to partner with 50 organizations around the world over the next three years as part of the initiative.
Chilean Indigenous association participates in key study for lawsuit against mining
- In a unique model for Latin America, a council of Lickanantay people in northern Chile created an environmental unit made up of hydrogeologists, engineers and environmental monitors from the territory’s communities to monitor the territory.
- Their study with a national university shows that the La Brava lagoon, located on the edges of the Atacama salt flat, is fed in part by the salt flat’s brine, which makes it vulnerable to mining activities established in the heart of the salt flat.
- Findings from the study were key in a lawsuit brought by the state defense council against three mining companies for irreparable damage to the Monturaqui-Negrillar-Tilopozo aquifer, the main water source for these lagoons.
More krill fishing and no new protected areas for Antarctic seas after latest talks
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) held its annual meeting Oct. 14-25 in Hobart, Australia.
- The international body comprised of 27 members is charged with conserving marine life in Antarctic waters, an area that is changing rapidly due to human-caused climate change.
- In 2009, the CCAMLR pledged to create “a representative network” of marine protected areas in the Southern Ocean, yet negotiations over four proposed MPAs have been at a standstill for years, due to repeated vetoes by the Chinese and Russian delegations.
- Despite a year of interim negotiations, CCAMLR members failed again at the latest meeting to reach agreement on creating any new marine protected areas and rolled back regulation of the burgeoning Antarctic krill fishery.
Protecting coral reefs boosts fish numbers by 10%: Study
- New research has found that the protection of coral reefs has boosted the amount of fish they harbor by around 10%.
- The study used survey data from about 2,600 reefs with varying levels of protection from overfishing.
- The team then built a statistical model to predict what would have happened if all reefs had not been protected, and the biomass, or collective weight of the resident fish, dropped by more than 10%.
- The scientists note their findings demonstrate that protections like marine protected areas are working and that greater coverage could lead to even more gains in fish biomass.
Researchers track koalas using innovative airborne DNA detection tool
What’s new: Researchers have successfully detected the presence of koalas and other threatened wildlife species using new tools that allow easy collection of airborne environmental DNA, according to a recent study. What the study says: It’s often difficult, time-consuming and expensive to collect data and observe threatened wildlife like koalas (Phascolarctos cinereus), small marsupials that […]
Combined effects of human activities increase risk to ecosystem services
- A global analysis finds that exposure to multiple human-caused stressors is reducing the ability of ecosystems to provide ecosystem services. However, precisely how these myriad human-induced environmental changes interact to disrupt ecosystems and alter these vital services is poorly understood.
- Researchers analyzed more than 1,000 experiments that measured the response of ecosystems to one, two or three human-caused environmental stressors. The scientists found that the ability of ecosystems to maintain their current function declines as the number of stressors they are exposed to increases.
- The scientists also analyzed data from a long-term experiment on the effect of four simultaneous environmental stressors on plant productivity. This single study showed that ecosystem services’ resistance to change gradually declines with long-term exposure to multiple environmental stressors.
- The new study sheds light on a crucial unanswered environmental science question: How do interactions between multiple planetary boundary transgressions accelerate the collapse of key Earth system processes that keep the planet habitable?
In Mexico, Totonac spiritual guides work with scientists to revive ecosystems
- Abuelos de Tajín, spiritual guides from Totonac communities in Mexico, say people are losing their traditional beliefs and ancestral knowledge as their connection with a fast-degrading environment rupture.
- Totonac spirituality is strongly connected to the surrounding ecosystem: Losing biodiversity can precipitate the decline of traditional beliefs, and this loss of traditional spirituality further ruptures values and duties to protect the ecosystem.
- To assess and tackle the state of biodiversity loss and contamination in their environment, the spiritual guides are working with researchers from the National Autonomous University of Mexico City. Preliminary results show the deforestation rate increased by 44.4% from 1986 to 2023 in one region.
- Spiritual guides are trying to restore and “renovate” their rituals, spirituality and community identity as a way to strengthen their connection to their environment, conserve it and live abundant lives.
In Venezuela, natural regeneration helps restore a threatened cloud forest
- Since 2018, El Tambor Project has been using assisted natural regeneration to restore native vegetation in a biodiverse and endemic species-rich cloud forest in the Venezuelan Andes.
- The project’s objectives include not only the restoration of the cloud forest, but also the protection of the wild fauna, such as the Andean bear (Tremarctos ornatus), which is threatened with extinction in Venezuela.
- To tackle risks for the cloud forest, El Tambor Project is also running educational programs on deforestation prevention and persuading landowners to allocate portions of their land for restoration efforts.
How do ‘rights of nature’ and ‘legal personhood’ laws differ, and what’s their conservation potential?
Nations across the globe are trialing “rights of nature” laws and “legal personhood” for various ecosystems and a range of reasons, from Indigenous reconciliation to biodiversity protection. While these two concepts are closely related, they have some key differences. Podcast guest Viktoria Kahui discusses what distinguishes them and how they’ve been used for conservation, while […]
Government inaction leaves Nepal without strategy to tackle invasive species
- A 2016 study ranks Nepal fourth globally in vulnerability to invasive species threats, particularly in agriculture.
- Yet despite drafting a management strategy to deal with the issue seven years ago, Nepal has still not finalized and implemented it.
- The country has identified 182 alien flowering plant species, with 27 considered invasive, affecting forests, agriculture and wildlife habitats.
- Experts stress the importance of swift action, noting that the window of opportunity to effectively manage invasive species is small.
Search for rare Nigerian damselflies finds forest habitats under threat
- Nigeria’s Cross River state, famed for its gorillas, chimpanzees, drill monkeys and forest elephants, is also part of an ecological region known to harbor the greatest diversity of dragonflies and damselflies in Africa.
- A Nigerian-Dutch team recently published details of three new species of dragonfly it found during its survey of four locations across the state, alongside dozens of other dragonflies and damselflies, including some that are now critically endangered.
- Many of the forests and streams the insects live in are threatened by fire, deforestation and the expansion of commercial oil palm plantations.
Birdsong rings out once again in Togo’s sacred forest of Titiyo
- Logging for firewood, charcoal and timber for construction almost wiped out the sacred forest of Titiyo in northern Togo.
- The degradation of the forest had a major impact on wildlife and the surrounding population.
- But since 2015, Sylvain Tchoou Akati, a native of the area, has led the restoration of this forest, and is today bringing his model of community-led conservation to other areas.
As climate change shakes up global map of venomous snakes, health risks abound
- Researchers assessed the impacts of climate change on 209 species of venomous snakes from now until 2070, and concluded that while some may disappear from their range, others are likely to expand to new areas.
- Venomous snakes are among the most dangerous animals on the planet, responsible for at least 80,000 deaths a year, mostly in low-income countries with limited access to antivenom.
- Another impact on public health is the reduction in drug development: snake venom has great pharmacological potential, contributing to the production of medicines used to treat illnesses ranging from cancer to heart failure.
- Ecosystems will also face an imbalance as new species move in and existing ones go extinct, since snakes play a critical role in controlling the population of other animals such as rodents, which are also disease vectors.
Scientists are racing to save South Asia’s butterflies from the threat of extinction
- Butterflies are some of Bangladesh’s most prolific pollinators and important ecosystem indicators.
- Insects, including butterflies, are especially vulnerable to climate change and other human-caused ecosystem changes.
- Despite the increasing threat of extinction, few legal protections or conservation initiatives focus on preserving butterflies and other insects.
- South Asian scientists are engaging communities in citizen science to garner attention to often-overlooked butterfly species.
Cambodia’s largest mangrove forest is ‘teeming with life,’ biodiversity survey finds
- A survey of biodiversity in Cambodia’s Pream Krasop Wildlife Sanctuary and Koh Kapik Ramsar site identified more than 700 unique species.
- The study also highlights how biodiversity is being lost due to threats including habitat loss and hunting; while this survey recorded rare species including otters and pangolin, a decade ago there would have been tigers and dugongs in the area.
- The researchers plan to conduct further surveys, focusing on the marine environment of the mangrove zone.
Rhino poop draws all the deer (and boars and more) to the yard, study finds
- Researchers have discovered that a variety of animals, from spotted deer to rhesus monkeys and peafowl, are attracted to and consume rhino excrement in Nepal’s Chitwan and Shuklaphanta national parks.
- The study used camera traps to record animal interactions with rhino dung, revealing that some animals eat the dung, the plants growing on it, the insects near it, or use the latrine areas for other activities.
- The findings suggest that translocation and reintroduction of even a few rhinos in their historical range can contribute positively to the restoration of the ecosystem.
Frog ‘saunas’ may help threatened frogs fight off deadly fungus
- Researchers have developed simple, sun-heated shelters that allow frogs to raise their body temperatures and fight off a deadly fungal disease called chytridiomycosis.
- The study focused on the green and golden bell frog in Australia, a threatened species, showing that frogs given access to these warm shelters cleared infections faster and developed resistance to future infections.
- This innovative approach could provide a valuable, low-cost tool for protecting various amphibian species threatened by the fungal disease, which has devastated amphibian populations worldwide.
- The research comes at a critical time, as a recent study found that two in five amphibian species are now threatened with extinction, with climate change becoming a primary threat.
New study reaffirms Indigenous lands key to mitigating climate change in Brazil
- A recent study adds to growing literature showing that Indigenous lands and conservation units are much more effective at regulating climate than multiuse areas.
- The authors found that Indigenous lands and conservation units contribute more to climate regulation than multiple-use areas, underscoring the crucial role that protected areas play in regional water supply services and mitigating ongoing climate change.
- However, persistent degradation pressures from forest fires, deforestation and global climate change are increasingly challenging the capacity of protected areas to regulate climate.
Zambian forest reserve rebounds with a little assistance
- Conservationists and farmers have restored large parts of a forest reserve in Zambia in just four years through natural regeneration.
- The Katanino Forest Reserve had lost more than 58% of its forest cover by 2019, when dozens of families living inside it and cutting trees to make charcoal were finally evicted by state officials.
- A restoration project launched that same year by conservation group WeForest and local partners has used assisted natural regeneration, a light-touch forest restoration method, to grow back more than 500 hectares (1,240 acres) of the reserve’s tree cover.
- The success is tempered by continued tree losses on farms outside the reserve, though WeForest is working to promote alternative livelihoods there that encourage farmers to protect trees on their land.
Peru puts endemic fog oasis under protection
- The Peruvian government has formally granted conservation status to the 6,449-hectare (16,000-acre) desert oasis site Lomas y Tillandsiales de Amara y Ullujalla on the coast of Peru.
- Lomas are unique ecosystems relying on marine fog that host rare and endemic plants and animal species. But they have become threatened by driving, land trafficking, urban development and mining.
- The site, the first of its kind to become protected after more than 15 years of scientific and advocacy efforts, will help scientists understand climatic and marine cycles in the area.
If forests truly drive wind and water cycles, what does it mean for the climate?
- Theoretical physicists Anastassia Makarieva and Viktor Gorshkov developed the controversial “biotic pump” theory more than a decade ago, which challenges traditional climate and hydrological science.
- The theory posits that forests drive moisture-laden air currents, thereby governing wind and rain and implying that further global forest loss could have unknown effects on weather and water supplies.
- While yet to be disproven or validated, some scientists say it’s vitally important to study and test this theory, and potentially include it in climate-modeling scenarios.
- Makarieva joins Mongabay’s podcast to discuss the theory and its implications for future climate modeling with co-host Rachel Donald.
Know your salamander: To conserve amphibians, study their intelligence (commentary)
- In the global amphibian crisis, salamander numbers across the species have dropped too, with around 60% of salamander species threatened with extinction. Researchers and conservationists need to start looking into amphibian intelligence to find new, effective ways to conserve them.
- Salamanders possess number system and memory post hibernation, and they show evidence of self-recognition, spatial reward learning and associating color with reward. Despite having a relatively simple brain structure, salamanders are capable of complex cognition, which can be used to save them from extinction.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
A Brazilian city restores its mangroves to protect against climate change
- A broad coalition of organizations is working to conserve and restore mangroves in the Greater Florianópolis area on Brazil’s southern Atlantic coast.
- Mangroves are critical tropical ecosystems that dampen coastal erosion, serve as nurseries for aquatic species, and store more carbon per hectare than terrestrial forests.
- These properties make mangroves a key part of coastal cities’ strategies to mitigate climate change and adapt to its consequences, such as rising sea levels.
Alaska’s Arctic rivers turn rusty orange as permafrost thaws
- Numerous rivers and streams in Alaska’s remote Brooks Range are turning orange due to the thawing of permafrost, which is releasing previously frozen minerals into the water.
- Water samples from the affected streams show higher acidity and higher concentrations of sulfates and trace metals, which can have significant ecological consequences, such as the disappearance of fish species and a decline in aquatic insect diversity.
- These water quality changes could severely impact Arctic fish populations, as many of the affected streams serve as crucial spawning grounds and nurseries for salmon and other fish species that are essential to the ecosystem and local subsistence fisheries.
- Researchers emphasize the need for further studies to understand the long-term implications of this issue, highlighting that the abrupt changes in water chemistry observed in the Brooks Range are a unique and concerning consequence of climate change in the Arctic.
An ancestral solution ensures water for Peruvian alpaca farmers, but is it enough?
- A community of alpaca farmers in the high Peruvian Andes is witnessing the loss of its mountain glaciers as a result of a warming climate and unseasonal droughts.
- In response, community members have turned to an ancestral practice of harvesting rainwater runoff and snowmelt, caching it in artificial lagoons that they can then tap to irrigate their alpaca pastures.
- Today, the community of Santa Fe, on the slopes of Mount Rit’ipata, has 41 of these lagoons, or qocha, but increasingly prolonged droughts mean it will need many more.
- Other communities across Peru have launched similar water harvesting initiatives, and while the government backs these projects, communities like Santa Fe are ineligible for state funding under a 2022 regulation.
Yucatán Peninsula’s hidden underground life tracks changes at the surface
- Scientists from Northwestern University in the U.S. led a series of underwater expeditions collecting water samples from the deep web of caves and sinkholes in the Yucatán Peninsula.
- The southeastern region of Mexico is crisscrossed by numerous flooded and interconnected tunnels, functioning as subterranean rivers — crucial arteries that maintain ecosystems and support millions of people, and connecting directly to the sea.
- Any disruptions to the microbial communities in these waters could have significant consequences for both humans and marine ecosystems.
- This research is crucial for assessing the potential environmental impacts of large-scale agriculture or major projects like the building of the Tren Maya railway line.
A fishing community celebrates its right to manage a Brazilian state park
- For the first time in Brazil, a traditional community has been awarded the concession to manage and operate visitor facilities inside a state conservation unit.
- The Caiçaras, a traditional fishing peoples, of Cardoso Island have lived in what is today Ilha do Cardoso State Park since the 19th century, and for decades faced pressure to leave the area.
- A year ago, when the concession for visitor facilities at the park went up for tender, they won a landmark court decision that found it was unconstitutional to bar them from bidding, given that it was on their territory.
- That led to the signing of a public-community partnership with the São Paulo state government, and in July 2023 the community formally took over managing accommodation services for visitors, cafeterias, education trails, a crafts shop and a visitors’ center.
Collective effort monitors Amazon wildlife in heavily logged Brazil state
- Indigenous communities, the government and civil society organizations are working to identify the status and whereabouts of animals in one of the most deforested states of the Brazilian Amazon.
- Devastated by the expansion of cattle ranching and soy farming, Rondônia has seen changes in the composition of its fauna due to alterations in the landscape.
- The initiatives for surveying and monitoring Rondônia’s fauna are being carried out in conservation units, Indigenous territories and restored forest areas on private lands; the goal is to guide conservation policies.
Messengers of the gods: Nara’s ‘sacred’ deer at a conservation crossroads
- Japan’s Nara city is famous for its sacred deer, protected for a millennium as “messengers of the gods” according to Shinto religious tradition, and today also a valuable tourism resource.
- In recent years, genetic analysis by Japanese researchers has found that Nara’s protected deer population has become genetically isolated over its history. But a nationwide deer population boom now threatens to end the Nara deer’s long isolation, potentially bringing diseases transmissible to humans, the scientists warn.
- In addition, deer overpopulation can harm farmers’ livelihoods and upset the balance of ecosystems. The Nara prefectural government is leading efforts to minimize community conflicts and ecological damage from both protected and “ordinary” deer.
- However, the researchers warn that even stronger deer management measures, including installing more deer-proof fences and expanded culling, may be necessary to address conservation and community conflict issues.
Chile to protect some salt flats, but selection lacks data, scientists say
- Ministers overseeing the Chilean government’s sustainability and climate change efforts have proposed a network of protected areas comprising 27 salt flats and lagoons, part of the country’s National Lithium Strategy.
- Another 26 salt flats will be exclusively used for exploration and extraction of lithium by national and international companies; two state-owned mining companies will lead operations in the country’s largest lithium reserves.
- Scientists and experts, however, have criticized the decision for not relying on scientific data.
As coffee expands in Bangladesh hills, conservationists worry about ecosystems
- Though coffee is not a native crop in Bangladesh, in the last couple of years, Bangladeshi farmers, especially those living in hilly regions, have been cultivating coffee thanks to favorable weather conditions.
- The government has been promoting coffee cultivation as a cash crop in places where major crops such as rice, wheat or maze are less suitable.
- However, experts say large-scale coffee cultivation, especially in hilly areas, will damage the diversity of the ecosystems, as the area has historically been rich in biodiversity.
New satellite data documents deforestation across ecosystems worldwide
- New satellite data documents the loss of vegetation in all types of ecosystems, not just tropical rainforests, around the world.
- The OPERA DIST-ALERT was developed by the makers of popular forest monitoring platform Global Forest Watch.
- The monitoring system incorporates managed forests, grasslands, shrublands and croplands along with tropical forests.
- The data obtained from two of NASA’s Landsat satellites and two of the European Space Agency’s Sentinel-2 satellites reflected lost vegetation around the world due to various factors — ranging from fires in Canada to logging in the Republic of Congo and cyclones in Malawi.
Venezuela’s shrimp farms push for sustainability against hardship and oil spills
- Venezuela’s aquaculture industry used to go unnoticed in a national economy revolving around the oil industry, but has gained prominence since 2019 despite revenue cuts and the economic crisis.
- Oil spills from disintegrating crude infrastructure compelled shrimp farms to move from an open system that took water from Lake Maracaibo and the Caribbean Sea, to a closed system that’s not only more profitable but also provides environmental benefits for communities and yields healthier shrimp.
- In 2023, farmed shrimp was Venezuela’s sixth-largest export by value; while the top export markets are in Europe, China has become the industry’s fastest-growing destination.
- While the industry has found ways to thrive amid adversity, it says it needs more help from the government, including on supplies of fuel and electricity, on research, and on nurturing a more secure and stable regulatory climate.
Bangladesh island’s switch from solar power to fossil fuels threatens birds
- The Bangladesh government recently converted off-grid Nijhum Dwip Island in the Bay of Bengal into an on-grid locality powered by fossil fuel-fired plants, posing a threat to the country’s second-largest mangrove forest.
- The island’s inhabitants had depended on individual solar-run power, and the government planned to install a mini solar grid for an uninterrupted power supply a few years back.
- Instead, the government has facilitated the construction of a 15 megawatt heavy-fuel-run power plant at Hatiya, the subdistrict headquarters of Nijhum Dwip, under the ‘100% Reliable and Sustainable Electrification Project,’ which seems to be a reverse transition from renewable to fossil fuel-based electrification.
- Nature conservationists believe that due to the connection to the national grid, human activities will increase around the forest and endanger the already cornered wildlife of the national park on the island.
Fishers, scientists restore mangroves on a Mexican isle wrecked by salt mining
- For decades, salt mining has deteriorated the wetlands and natural flood patterns of Isla del Carmen, part of Bahía de Loreto National Park in Mexico.
- Collaboration between two conservation organizations and a community of fishers on the mainland are working to restore the mangroves of Isla del Carmen by rehabilitating its hydrology and constructing “vegetation terraces” for the trees.
- The project also involves training and educating communities about the importance of conserving the ecosystem for the sake of wildlife, the local economy and protecting against the effects of climate change.
Saving Asia’s fishing cat means protecting threatened wetland habitat
- Fishing cats are uniquely adapted to life in wetlands, possessing a double-layered coat that serves as a water barrier and insulation, partially webbed feet, ears that plug when submerged, and a curious call reminiscent of a duck.
- Spread across Asia, this small wild cat species faces myriad threats, including habitat loss, hunting and retaliatory killings, road kill, and more. Considered vulnerable across its range, the felid is also elusive and underresearched, with many knowledge gaps about its distribution and ecology.
- Conservationists are working across its range to raise the profile of this wildcat, reduce threats and understand the species. Linking its protection to equally threatened wetlands is vital, they say. Initiatives such as the Fishing Cat Project in India have achieved success in making this cat the face of these habitats.
- Multiple conservation and research projects operate in Asia under the banner of the Fishing Cat Conservation Alliance, a cooperative model that provides funding lifelines and enables international collaboration to protect this small cat.
Malawi police arrest elephant poachers in Kasungu National Park
- Police and wildlife authorities in Malawi have arrested two men suspected of having killed an elephant in Kasungu National Park.
- Residents of villages just outside the park’s boundaries informed police about two men selling elephant meat, who were subsequently found in possession of 16.6 kg (36.6 lbs) of ivory.
- Kasungu forms part of a transfrontier conservation area that extends into Zambia, a previous poaching hotspot where authorities have spent the past five years strengthening enforcement in collaboration with the International Fund for Animal Welfare.
- In July 2022, 263 elephants were translocated to Kasungu from Liwonde National Park in southern Malawi; communities have reported increased raids by elephants on farms and granaries since then, with four people killed by elephants between July and October.
‘Planting water, eating Caatinga & irrigating with the sun’: Interview with agroecologist Tião Alves
- In an interview with Mongabay, Brazilian agroecologist Tião Alves tells how he has been teaching thousands of rural workers to survive in the Caatinga biome, severely afflicted by drought, climate change and desertification.
- At the head of Serta, one of the most important agroecology schools in the Brazilian Northeast, he teaches low-cost technologies that ensure food security with a minimum of resources, both natural and financial.
- Currently, 13% of the Caatinga is already in the process of desertification, the result of a combination of deforestation, inadequate irrigation, extreme droughts and changes in the global climate.
Rising temperatures threaten the tiny animals responsible for groundwater quality
- A new study compared temperatures inside 12 caves around the world with their respective surfaces, showing that average annual temperatures in underground systems tend to mirror those of the surface, but with far less variation.
- The researchers also found that while some caves follow outdoor temperatures with little or no delay, others have temperatures that are very asynchronous with the surface, being at their warmest when the world outside is at its coldest, and vice versa.
- Scientists also detected the existence of daily thermal cycles in the deepest sections of some caves, suggesting that such cycles might mark the circadian rhythms of cave-adapted organisms.
- The results indicate that underground fauna — with many species ill-adapted to handle large temperature variations — might be at threat due to climate change, and that their extinction might risk the water quality of aquifers worldwide.
Huge new no-fishing zones give Antarctic marine predators and their prey a break
- The government of the South Georgia and South Sandwich Islands (SGSSI), which operates as a British overseas territory, recently announced that it had established new no-fishing zones over 166,000 km² (64,100 mi²) of its existing marine protected area, and prohibited krill fishing in an additional 17,000 km² (6,600 mi²) of the MPA.
- These new no-fishing zones were established to protect krill-dependent marine wildlife, including baleen whales and penguins, while also considering the fisheries operating in the area, which target krill and other species.
- While conservationists initially pushed for further protections, they ultimately accepted the decision, with one calling it a “positive and good outcome.”
- However, Argentina, which claims the South Georgia and South Sandwich Islands as part of its Tierra del Fuego province, has expressed its dissatisfaction with the SGSSI government’s decision.
How a wind farm on Brazil’s coast erased a fishing village from the map
- Environmental authorities approved what was then the largest wind farm in Brazil’s Ceará state in 2002 without assessing its socioenvironmental impact, including on the local fishing community and the ecosystem.
- The community resisted and ended up receiving unusual compensation that nonetheless failed to resolve the permanent problems and triggered internal conflicts.
- With support from a state university, the residents have fought against their erasure from the official records, but today are entitled to the use of a smaller territory than they had before, and have lost access to natural resources like lagoons.
Brazil risks losing the Pampa grassland to soy farms and sand patches
- Nearly a third of the Brazilian portion of South America’s Pampa grassland has been lost since 1985, largely to agricultural expansion and forestry plantations.
- This biome is often overlooked in comparison to the higher-profile Amazon, Pantanal and Cerrado landscapes, but has greater plant diversity than the others.
- The expansion of agriculture may also be exacerbating an age-old problem in the Pampa, which is the spread of barren, sandy patches of land.
- Efforts to reverse this process, known as arenization, often involve growing eucalyptus plantations, but experts say this commercial approach solves nothing.
Norway pension fund breaks with U.K. conglomerate Jardines over endangered orangutan habitat
- Norway’s state pension fund, the world’s largest sovereign wealth fund, has cut ties with Jardine Matheson (Jardines) due to concerns that the conglomerate’s gold mining activities in Indonesia could damage the only known habitat of the world’s most threatened great ape, the Tapanuli orangutan (Pongo tapanuliensis).
- The fund joins 29 financiers that have excluded Jardines and/or its subsidiaries from financing due to climate and environmental concerns, according to data from the Financial Exclusions Tracker.
- The Tapanuli orangutan was only first described in 2017, and its estimated population numbers fewer than 800 that survive in a tiny tract of forest; 95% of the ape’s historical habitat has been lost to hunting, conflict killing and agriculture.
- The Martabe mining concession in northern Sumatra lies in the portion of the orangutan’s habitat, the Batang Toru forest, with the largest orangutan population, where the probability of the species’ long-term survival is highest; the fund worried that further expansion of the mine would increase threats to the ape.
Indonesian gold mine expanding in ‘wrong direction’ into orangutan habitat
- A gold mine in the only known habitat of the critically endangered Tapanuli orangutan is expanding, prompting alarm from activists and conservationists.
- The Martabe mine on the Indonesian island of Sumatra, run by a company associated with the U.K.’s Jardine Matheson Holdings, already cleared 100 hectares (about 250 acres) of forest from 2016 to 2020, and looks set to clear another 100 hectares.
- Advocacy group Mighty Earth says the expansion will impact an area recently established to help protect the orangutan and other threatened species.
- Jardines says an independent forestry and sustainability assessment concluded that the long-term impact of the planned exploration and development work was minimal.
Project retraces Darwin’s voyage, educating young conservation leaders
- The DARWIN200 Project is retracing English naturalist Charles Darwin’s 19th-century voyage, stopping at 32 ports around the globe by 2025.
- The sailing ship’s crew is composed of 200 young people who work in environmental conservation around the world, taking turns aboard the vessel to learn about projects in the places where they moor.
- Mongabay visited the ship as it passed through Rio de Janeiro together with Sarah Darwin, Charles Darwin’s great-great-granddaughter.
On Kaho’olawe, new technology could restore a sacred Hawaiian island
- The small Hawaiian island of Kaho‘olawe is a sacred site for Indigenous Hawaiians, who used it for navigational training, religious ceremonies, and fishing.
- But the island has faced decades of ecological destruction due to invasive plants and animals, erosion, and bombings as a test site by the U.S. military.
- A new conservation project has successfully tested a novel method using AI-equipped camera traps and an aerial drone to collect images of invasive cats, which have destroyed the island’s seabird populations, in dangerous and difficult-to-access parts of the island.
- But funding for the work on Kaho‘olawe remains scarce, and the drone project is now on hold as local organizations seek further funding to deal with the feral cats.
A highway project in Chile threatens one of the world’s longest-living tree species
- The Chilean government’s intention to build a final section of a highway through a national park has caused concern among scientists and environmentalists.
- In a letter published in the scientific journal Science, scientists warn that the road will destroy hundreds of the longest-living trees in the world.
- Scientists are also concerned that the road, which may allow large trucks, would impact numerous other endangered species in the park, including a rare canine and small wild cat.
UN award for Nepal’s tiger range restoration spurs euphoria amid challenges
- Nepal’s Terai Arc Landscape (TAL) initiative, aimed at restoring ecosystems and creating space for tigers, receives global recognition from the U.N. as one of seven World Restoration Flagships.
- Launched in 2004, the TAL initiative restored 66,800 hectares (165,000 acres) of forest and significantly increased the Bengal tiger population in the region.
- The U.N. recognition opens doors for technical and financial support to restore an additional 350,000 hectares (865,000 acres) in both Nepal and India, but overcoming challenges like infrastructure expansion and human-wildlife conflict remains critical for long-term sustainability.
The new Arctic: Amid record heat, ecosystems morph and wildlife struggle
- Every species of animal and plant that lives or breeds in the Arctic is experiencing dramatic change. As the polar region warms, species endure extreme weather, shrinking and altered habitat, decreased food availability, and competition from invading southern species.
- A wide array of Arctic organisms that rely on sea ice to feed or breed during some or all of their life cycles are threatened by melt: Over the past 40 years, the Arctic Ocean has lost about 75% of its sea ice volume, as measured at the end of the summer melt season. This translates into a loss of sea ice extent and thickness by half on average.
- Researchers note that the rate of change is accelerating at sea and on land. While species can adapt over time, Arctic ecosystem alterations are too rapid for many animals to adapt, making it difficult to guess which species will prevail, which will perish, and where.
- The only thing that could limit future extinctions, researchers say, is to quickly stop burning fossil fuels, the main driver of climate change.
Amazon catfish must be protected by the Convention on Migratory Species COP-14 (commentary)
- The latest Convention on Migratory Species of Wild Animals (also known as the Bonn Convention) meeting (COP-14) is taking place in Uzbekistan this month, and the government of Brazil has proposed protections for two catfish species with extraordinary migrations, the dorado and piramutaba (manitoa).
- The dorado’s migratory journey for instance spans a distance of 11,000+ kilometers round trip, from the Andes to the mouth of the Amazon River, and along the way it connects multiple ecosystems and feeds local and Indigenous fishing communities, but is under increasing threat.
- “During COP-14, the dorado and piramutaba will take a prominent place thanks to the Brazilian Government’s proposal to include them in CMS Appendix II…It is essential that the governments at the meeting adopt Brazil’s proposal,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Where sea otters play, salt marshes stay, new study shows
- A new study has found that sea otters are helping to slow down salt marsh erosion in Elkhorn Slough in California by eating burrowing crabs.
- Drawing on a range of data sources, which included surveys and field experiments, the authors found that in places where sea otters were abundant, the erosion of the salt marsh slowed by as much as 80-90% over the course of the study.
- Salt marshes worldwide are disappearing due to climate change-driven factors such as rising sea levels and other human pressures.
Livelihoods at stake as Lake Victoria’s papyrus swamps come under pressure: Photos
- The papyrus swamps at the edges of Lake Victoria in East Africa have for generations provided a livelihood to communities living here.
- While some harvest reeds to make into mats, baskets, and handicrafts, others catch the plentiful fish that nurse in the shelter of the reedbeds.
- The swamps are also home to birds that have become specialized to live amidst the papyrus reeds in a narrow geographic range, while the reedbeds serve as filters taking up nutrients and retaining sediment — in the process also allowing carbon storage through the buildup of significant detritus and peat deposits.
- However, development pressure for new resorts and farmland is putting this ecosystem under threat, while the introduction of the Nile perch here in the 1950s has devastated native fish species.
Courage & calm despite attacks: Q&A with Colombian activist Yuly Velásquez
- For years, Colombia’s largest oil refinery, owned by the national oil company Ecopetrol, has discharged oil and toxic waste into water bodies, impacting fish and the livelihoods of fishers.
- Yuly Velásquez, a local fisher and president of an environmental organization, has spent years documenting water contamination and corruption linked to the refinery, and she faces consistent threats and attacks.
- According to a 2022 report by the NGO Global Witness, Colombia is the most dangerous country in the world for environmental and land defenders, with 60 murders that year.
- In this interview with Mongabay, she discusses the threats environmental defenders face in Colombia and what helps her stay resilient in the face of attacks.
Illegal gold mining threatens Indus River water and biodiversity in Pakistan (commentary)
- The Indus River in Pakistan is being extensively disturbed by unregulated mining of the river’s bed (‘placer mining’) for gold.
- Numerous operations employing an estimated 1,200 heavy machines dig daily into the riverbed and dump buckets of sediment and rocks into screening devices, destroying habitat and muddying the water flowing downstream.
- “It is crucial to the development for the region’s economy and environmental preservation efforts to regulate placer gold blocks along the Indus River,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Salmon and other migratory fish play crucial role in delivering nutrients
- Pacific salmon can play a key role in transporting nutrients from marine to freshwater and terrestrial ecosystems.
- In the past, Pacific salmon and other anadromous fish that spawn in freshwater and spend part of their life in the ocean likely played a much larger role in global nutrient cycles, scientists find.
- But today, many populations of Pacific salmon and other anadromous fish are under pressure from habitat loss, overfishing, climate change, dams and other pressures that have greatly reduced their numbers, weight and ability to migrate freely.
- Population declines could further curtail their role in global nutrient transport in future, with increasing consequences, especially for nutrient-poor ecosystems that have relied in the past on migratory fish for significant nutrient additions.
In Brazil’s Caatinga, adapted agroforests are producing food from dry lands
- In northeastern Brazil, the model known as Agrocaatinga has proven to be the most productive and effective in increasing food security for families, generating income and preserving native vegetation.
- Previously degraded lands now produce around 50 types of food, thanks to the combination of an agroforestry system with rainwater harvesting techniques.
- Agrocaatingas emerged from the commercial demand for wild passion fruit, a native fruit that today yields up to $600 per harvest for families — four times the local per capita monthly income.
In Brazil’s Caatinga, these families excel in farming productivity
UAUÁ, Bahia, Brazil — In northeastern Brazil, the innovative Agrocaatinga model is revolutionizing food security, income generation, and native vegetation preservation. This sustainable approach combines agroforestry with rainwater harvesting techniques, revitalizing previously degraded lands to produce over 50 different food types. Originating from the growing commercial demand for wild passion fruit, this model enables families […]
Long-term wildlife impacts at Chornobyl, Fukushima may yield ‘a new ecology’
- The world’s worst nuclear power plant accidents to date, at Chornobyl, Ukraine, in 1986, and Fukushima, Japan in 2011, and the human exclusion zones created around them have given scientists a unique opportunity to study the effects on wildlife of radiation and of reduced pressure from people.
- Chornobyl disaster findings regarding the impacts on exclusion zone organisms vary: Some point to a resurgence of the studied wildlife in the absence of humans, while others indicate radiation negatively impacting certain animal populations.
- Fukushima radiation impacts are statistically harder to detect. But scientists have made similar observation to Chornobyl: Some, but not all, species appear to thrive from reduced human pressure.
- Radioactive contamination moves in ecosystem-specific ways, depending on factors such as water flow. A combination of radioactive contamination and reduced human activity in nuclear exclusion zones may be giving rise to “a new ecology,” with nature overall neither suffering nor thriving, simply different in the impacted areas.
New dams in Cambodia pit ‘green’ hydropower against REDD+ project
- The recent approval of two hydropower dams in Cambodia’s Cardamom Mountains could undermine a REDD+ carbon project in the area.
- The Southern Cardamom REDD+ Project relies on keeping the forests in this region standing — a goal researchers say is “completely incompatible” with the forest clearing and flooding necessitated by the new dams.
- The lack of transparency inherent in both the carbon market and the Cambodian government means that the fate of the Cardamoms remains unclear for now.
Bird-friendly maple syrup boosts Vermont forest diversity & resilience
- A relatively new program in Vermont is helping both maple syrup-producing farms and their customers to improve forest habitat preferred by a diversity of bird species.
- Launched in 2014, the Bird-Friendly Maple Project furnishes a logo to qualifying farms for use on their products, if they can demonstrate that the forests where they tap sugar maple trees contain a diversity of trees and shrubs, which improves the woodlands’ structure and foraging and nesting opportunities for birds.
- Creating a biologically diverse farm is a major tenet of the sustainable agriculture technique of agroecology, because it leads to greater resilience and health of the farm, its farmers and its wildlife.
- Maple syrup operations included in the program cover 7,284 hectares (18,000 acres) of forests via 90 participating farms as the program is now being replicated in New York, Massachusetts and Maine.
Protecting the Brazilian Caatinga from desertification
UAUÁ, Bahia, Brazil — In northern Bahia, 35 communities have united to protect and restore nearly 100,000 acres of the unique Caatinga dry forest in northeastern Brazil. Through the Recaatingamento project, families are learning essential skills to conserve native vegetation, manage goat overpopulation, and explore sustainable income sources, such as foraging for wild fruits. The […]
‘Immense body of knowledge’ at stake in Cambodia’s Prey Lang as deforestation soars
- Researchers have launched a new book that catalogs hundreds of plant species from Cambodia’s Prey Lang Wildlife Sanctuary that have known medicinal uses.
- The book draws on the knowledge of Indigenous communities who have found a use for these plants over the course of generations, and whose livelihoods and cultures are closely intertwined with the fate of these species.
- The book also serves to highlight the imperiled situation of Prey Lang and its native species as deforestation by politically linked timber-trafficking networks continues to destroy vast swaths of this ostensibly protected area.
- “If the current trends of deforestation continue,” the authors warn, “an immense body of knowledge about nature will be lost, reducing the resilience and adaptability of future generations.”
Wild by nature: Ecological restoration brings humanity and biodiversity together
- Ecological restoration is “an attempt to design nature with non-human collaborators” in response to the biodiversity crisis.
- The very idea that nature is something outside of society often hampers practical solutions, and is an impediment to restoring ecosystems, Laura Martin, associate professor of environmental studies at Williams College, argues in this episode of the Mongabay Newscast.
- In this podcast conversation, co-host Rachel Donald speaks with Martin about the shift in mindset required to tackle biodiversity loss that centers on a restorative approach that’s human-inclusive and mobilizes public participation rather than exclusion.
Colombian Amazon park rangers face violence, threats by illegal armed groups
- In the last five years, at least 15 threats have been reported against the park rangers who guard the protected areas of the Colombian Amazon. Other issues include the transfer of personnel due to violence, the burning and looting of five control checkpoints and several deaths between 2008 and 2011.
- By overlapping data from the organization Indepaz about the presence of illegal armed groups and the locations of protected areas in the Colombian Amazon, it was determined that these groups are present in 35 of the 39 municipalities that include protected areas. In some cases, FARC dissidents ordered park rangers to leave and declared them “military objectives.”
- In four Amazonian protected areas, almost 2.5 tons of cocaine were seized between 2017 and 2022, after the signing of the peace agreement.
A community-led strategy to save Brazil’s dry forests from desertification
- In northern Bahia state, 35 communities have come together to conserve and recover close to 100,000 acres of Caatinga dry forest in northeastern Brazil.
- With the Recaatingamento project, families learn to preserve native vegetation, control the overpopulation of goats, and invest in sustainable sources of income, such as gathering wild fruits.
- Affected by recurrent droughts, the Caatinga is one of the regions most susceptible to climate change in the world; it’s also Brazil’s third-most deforested biome, which contributes to accelerating desertification — 13% of the soil there is already sterile.
Thailand tries nature-based water management to adapt to climate change
- With an economy largely underpinned by irrigated crops like rice, water is a crucial resource in Thailand. But as climate change exacerbates floods and droughts in the country, sustainable water management is an increasing challenge.
- Nature-based solutions that incorporate the natural processes of the country’s abundant rivers, floodplains and watershed forests are beginning to be trialed via various projects at large and small scales.
- A new report assesses the efficacy of two nature-based approaches to water management in Thailand, which represent a step away from the country’s typically top-down, hard-engineering approach and present several benefits to the environment and communities.
- However, environmental and societal tradeoffs, complex policy frameworks, and the need for greater understanding and expertise around the concept, design and implementation of nature-based approaches are barriers to their widespread implementation.
Amazonian expedition searches out rare ‘fish from the clouds’
- Researchers carried out a massive survey in the Brazilian Amazon for so-called annual rivulids, a family of fish whose eggs survive in a hibernation state during drought and then hatch when it rains — a phenomenon that’s earned them the name “fish from the clouds.”
- There are 200 species of annual rivulids in Brazil, nearly half of which are at risk of extinction; their fragile ecosystems — ponds, swamps and marshes — are highly vulnerable to infrastructure works like highways, ports and hydroelectric dams.
- Little studied in the Amazon, these species are subjected to stress brought on by human occupation; three new endemic species discovered during the expedition live in the Belo Monte hydropower dam’s area of influence.
- The survival of annual rivulids could be guaranteed by environmental licensing laws, but proposed legislation currently in the Senate could weaken those guidelines.
Keeping herbivores at bay helps in early stages of restoration, studies show
- Excluding herbivores from restoration areas may lead to an increase in both vegetation abundance and plant diversity, according to a new analysis.
- The global-scale analysis, which reviewed hundreds of studies, found that herbivores tend to be more common in areas undergoing restoration and can slow down vegetation recovery.
- While native herbivores play a crucial role in healthy ecosystems, researchers argue it may be beneficial to keep them from entering heavily degraded areas in the early stages of restoration.
- The impact of herbivores on restoration varies, and project managers should consider timing and local conditions when deciding whether to exclude, tolerate, or introduce herbivores.
Forest restoration to boost biomass doesn’t have to sacrifice tree diversity
- Restoring degraded forests to boost biodiversity, store carbon and reconnect fragmented habitats is a burgeoning area of tropical forest conservation.
- But uncertainty remains around the long-term impacts of various restoration approaches on forest biodiversity and functioning, with experts suggesting, for instance, that overly focusing on biomass accumulation for climate mitigation can come at the expense of species diversity.
- A new study in Malaysian Borneo has found that actively restoring logged forest plots with a diversity of native timber species, coupled with management of competitive vegetation, actually boosted adult tree diversity after nearly two decades compared to plots left to regenerate naturally.
- While the results add to a growing body of evidence that active restoration can lead to biodiversity gains, the authors caution that restoration approaches must be conducted in ecologically sensitive ways to avoid unintended outcomes.
The tricky business of commercializing invasive plants to death
- To control the spread of invasive plants, some have offered a different solution: harvest and sell the invaders into extinction.
- But as some initiatives show, making and selling artisanal products from invasive species can come with social, economic and ecological challenges.
- Instead, some conservationists and researchers say that invasive plants may need to be removed at large scales for industries like biofuel, and not just to make artisanal products.
- While some researchers worry this could incentivize keeping invasive plants around, advocates of commercialization contend that for some species, large-scale economic use might be the only way to control their spread.
How scientists and a community are bringing a Bornean river corridor back to life
- Decades of deforestation to make way for oil palm monoculture have transformed the Kinabatangan River floodplain in east Sabah, Malaysian Borneo, dividing wildlife populations and confining many of the region’s most iconic species to small fragments of forest that cling on along the river.
- Local communities and conservation initiatives are working together to restore and reconnect pockets of remaining habitat along the river to preserve the vital wildlife corridor, but restoration in the unpredictable and often-waterlogged floodplain is notoriously difficult.
- One such initiative, Regrow Borneo, is facing the challenge by leveraging the expertise of scientists and local knowledge of community members who have been planting forests along the Kinabatangan for decades.
- They say that by focusing their approach on a model that benefits both people and wildlife, they hope their program inspires others to shift away from simply planting numbers of trees toward restoring forests where they’re most needed, including in areas that present challenging conditions.
Study shows dire outlook for amphibians: 40% threatened with extinction
- A global survey of 8,000 amphibian species by the IUCN reveals that 40% of them are at some risk of extinction: 2,873 species in total.
- Brazil is the country with the greatest amphibian diversity in the world, home to around 1,200 species, and according to the new study, 189 are threatened, most of them endemic.
- Deforestation and lethal fungi had already been noted as causes of the decline, but now biologists are highlighting the role of the climate crisis: High temperatures and low humidity affect the amphibians’ breathing, which is partly done through the skin.
- Amphibians are important bioindicators of ecosystem health, as well as being crucial for pest control and medicine.
New platform offers toolkit for companies to prove their eco claims
- As governments around the world consider new regulations that would require corporations to track their impacts on biodiversity, a new platform called NatureHelm provides companies and individual landowners with a tool to track indicators of ecosystem health.
- The tool analyzes various databases and scientific papers to find relevant local biodiversity targets and automatically pulls in data from remote tools, such as camera traps, to track them.
- NatureHelm also provides consulting to help companies choose the best tools to track biodiversity targets, and produces annual reports that allow companies to show how different metrics change over time and in response to conservation actions.
As U.S. insurers stop covering prescribed burns, states and communities step up
- Prescribed fires are a positive land management method, but when the flames occasionally escape control, the resulting damage to land and private property also hurts this conservation tool’s reputation.
- U.S. insurance companies are thus charging increasingly unaffordable premiums for coverage of this activity or are dropping the service altogether in the wake of some particularly large recent accidents.
- As a result, many small conservation groups and private businesses are getting out of the habit of using fire to improve grassland health, boost wildlife habitat, and decrease likelihood of catastrophic wildfires.
- California is bridging this gap with a new state program that insures the activity, while prescribed fire associations, where residents and firefighters cooperate to carry out burns on private land, are increasingly popping up in communities.
Forest elephants are the ‘glue’ holding Congo rainforests together
- African forest elephants play a vital role in shaping the environment and composition of the Congo Basin rainforest, including the giant carbon-sequestering trees it is noted for.
- Without them, the Congo rainforest would lose carbon stocks and biodiversity, and the composition of the forest itself would change.
- Yet the full ecological value of this charismatic species — and the ecosystem impacts if it is lost — are not fully understood, so increased funding for study and conservation is needed, experts say.
- On this final episode of the Mongabay Explores the Congo Basin podcast season, Andrew Davies, assistant professor of organismic and evolutionary biology at Harvard University, and Fiona “Boo” Maisels, a conservation scientist at the Wildlife Conservation Society, detail the unique value of forest elephants, what still remains unknown, and why urgent protection is needed.
To keep track of salmon migrations in real time, First Nations turn to AI
- Partnering with First Nations, a new interdisciplinary study proposes harnessing artificial intelligence and computer-based detection to count and produce real-time data about salmon numbers.
- Monitoring their population when they return to the rivers and creeks is crucial to keep tabs on the health of the population and sustainably manage the stock, but the current manual process is laborious, time-consuming and often error-prone.
- Fisheries experts say the use of real-time population data can help them make timely informed decisions about salmon management, prevent overfishing of stocks, and give a chance for the dwindling salmon to bounce back to healthy levels.
- First Nations say the automated monitoring tool also helps them assert their land rights and steward fisheries resources in their territories.
A mobile solution for Kenyan pastoralists’ livestock is a plus for wildlife, too
- The use of mobile bomas, or corrals, to keep livestock safe from predators has shown a wide range of benefits for both pastoral communities and wildlife in Kenya’s Maasai Mara.
- The bomas reduce the risk of disease and predation among livestock, while allowing for the regeneration of degraded grazing land, which in turn draws in more wild herbivores to the area.
- The increased wildlife presence has led to a rise in wildlife tourism, valued at $7.5 million annually in the 2,400-hectare (6,000-acre) Enonkishu Conservancy.
- Observers warn of potential downsides, however, including food insecurity as community members abandon farming in favor of more lucrative tourism work, and a rise in human-wildlife conflict as the area’s wildlife population grows.
Amid record melting, countries fail again to protect Antarctic waters
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with protecting marine life and managing fisheries in the Southern Ocean, met from Oct. 16-27 in Hobart, Australia, with 26 member countries and the European Union participating.
- For the seventh year in a row, the CCAMLR declined to establish new marine protected areas (MPAs) around Antarctica, despite having committed to creating “a representative network of MPAs” in 2009.
- Scientists, conservationists and some governments have been pushing for greater protections, concerned that the melting ice in Antarctica has reached alarming levels, jeopardizing some key populations of penguins, krill, whales, seals and other marine animals.
- The stalemate came even as a new threat to wildlife emerged in the region: the discovery last week that a virulent form of avian flu had reached Antarctic bird colonies.
South Africa’s penguins heading toward extinction; will no-fishing zones help?
- With just 10,000 breeding pairs left, the endangered African penguin (Spheniscus demersus) could be extinct in the wild by 2035 if the current rate of population decline continues.
- To protect the bird’s food supply and slow its population collapse, South Africa is throwing a protective no-fishing cordon around its main breeding colonies for a period of 10 years.
- But the devil is in the details, and conservationists say the cordons are too small to ensure the penguins get enough fish.
- Negotiations over whether to adjust the cordons are continuing in advance of an early 2024 deadline.
Brazil’s Indigenous communities turn to native beekeeping to recover nature
- Indigenous territories located in different Brazilian biomes — the Amazon, the Cerrado and the Atlantic Forest — are hosting beekeeping projects aimed at both generating an income and restoring local ecosystems.
- The community projects show how these efforts, associated with agroecological food production, can improve quality of life, especially in the face of climate change impacts.
- The movement began four years ago with a crowdfunding campaign to establish beekeeping in the Amazon, and today includes 53 traditional communities involved in native beekeeping across the country.
Gone before we know them? Kew’s ‘State of the World’s Plants and Fungi’ report warns of extinctions
- The Royal Botanic Gardens, Kew’s “State of the World’s Plants and Fungi” report assesses our current knowledge of plants and fungal diversity, the threats they face and how to protect them.
- The report warns that many plant and fungal species, 45% of documented flowering plants and half of all analyzed fungi risk extinction (though less than 0.4% of identified fungi have been assessed for extinction to date).
- The report identified 32 plant diversity darkspots, places where plants are highly endemic but severely under-documented, including Colombia, New Guinea and China South-Central.
- Report authors argue that priority conservation areas should consider distinctiveness in plants or “phylogenetic diversity” and found that these hotspots of phylogenetic diversity differ from the traditional biodiversity hotspots approach.
Restoring degraded forests may be key for climate, study says
- Scientists have found that focusing on restoring degraded forests, which cover more than 1.5 billion hectares (3.7 billion acres) globally, can enhance forest carbon stocks more efficiently than replanting in deforested areas, with natural regrowth being a cost-effective method.
- In Central America’s “Five Great Forests,” there’s a goal to restore 500,000 hectares (1.2 million acres) by 2030. The study identified 9.8 million hectares (24.2 billion acres) as top restoration priorities, with 91% being degraded forests.
- Restoring just 5% of these priority zones was calculated to potentially sequester 113 million tons of CO2, equivalent to taking more than 20 million cars off the road for a year.
- The research emphasizes the importance of involving local communities in restoration planning and suggests that current forest management practices, like those in the timber industry, need to adapt for more sustainable outcomes.
99% of Caatinga biome could lose plant species due to climate change: Study
- An unprecedented study analyzed 420,000 occurrence records for 3,060 Caatinga plant species and concluded that 99% of the plant communities there are expected to lose species by 2060.
- Even though the species in the biome are theoretically adapted to extreme climates, researchers found that the Caatinga is much more vulnerable to climate changes than previously believed.
- Protecting the more sensitive areas and restoring landscape vegetation connectivity is crucial for the resilience of Caatinga ecosystems; the biome is one of Brazil’s least protected, as less than 9% of its area lies within Conservation Units.
World owes it to Tanzania to keep Eastern Arc forests standing, study shows
- Tanzania’s Eastern Arc’s evergreen forests provide carbon sequestration that the world benefits, yet it’s local communities alone who shoulder the costs of keeping the forests standing.
- The authors of a new study recommend that international investments in conservation within the Eastern Arc worth $2 billion need to be made over the next 20 years.
- Without this, the authors say, the mountains’ forests and their extraordinary levels of biodiversity will be lost or degraded as local communities convert them to agricultural land or harvest timber from them.
Frogs in the pot: Two in five amphibian species at risk amid climate crisis
- The extinction risk for more than 8,000 amphibian species has significantly increased in the past 18 years, primarily due to climate change impacts, with two in five amphibians now threatened, a new study shows.
- Amphibians are particularly vulnerable because of their permeable skin and specific habitat needs; diseases like the chytrid fungus further threaten their survival.
- Salamanders are the most at risk, with a lethal fungus in Europe posing a significant threat, especially to the diverse salamander population in North America.
- The study emphasizes the importance of global conservation efforts, with habitat protection showing positive results for some species, and highlights the broader context of the ongoing global biodiversity crisis.
Forest restoration can fare better with human helping hand, study shows
- A two-decade-old experiment in the tropical rainforest of Sabah, Malaysian Borneo, is beginning to reveal that human-assisted restoration of logged forests can increase the speed of an ecosystem’s recovery.
- The researchers also found that planting a diverse suite of seedlings, instead of only one species, led in just one decade to greater biomass and forest complexity.
- The study provides more weight to the argument that greater forest species diversity in general — and specifically for restorations — delivers more ecosystem services, possibly including carbon sequestration.
- However, there is the possibility that the particular life cycle of the type of trees used in this study — hardwood tropical species from the Dipterocarpaceae family, chiefly found in Southeast Asia — could have especially enhanced diversity in this case.
From rat-ridden to reserve, Redonda is an island restoration role model
- In 2016, conservationists began restoring the island of Redonda, part of Antigua and Barbuda in the Caribbean, by removing invasive rats and goats.
- Shortly after removing these invasive species, vegetation on the island sprang back to life, and seabirds and other wildlife recolonized the island.
- In September 2023, the government of Antigua and Barbuda announced it had established the Redonda Ecosystem Reserve, covering nearly 30,000 hectares (74,000 acres) of land and sea.
- Experts say they hope Redonda’s restoration and successive protection will be used as a model for similar projects across the Caribbean.
NASA satellites reveal restoration power of beavers
- A new partnership between NASA and researchers is measuring the impact of beavers reintroduced to landscapes in Idaho.
- Beavers are one of the world’s most powerful ecosystem engineers, building new habitats by slowing water flow and reducing flooding, while also boosting biodiversity.
- Beavers are all the more important in an age of rapid climate change, as they produce wetter and more resilient habitats, even in the face of wildfires.
- “NASA is interested in how satellite Earth observations can be used for natural resource management,” a member of the space agency’s Ecological Conservation Program tells Mongabay.
In the clash over Dutch farming, Europe’s future arrives
- Despite months of protests by farmers and an electoral rebuke, the Dutch government has pressed ahead with an attempt to make its farming system more ecologically sustainable.
- But there are deep divisions in the Netherlands over how extensive any reforms should be, and clashes over the role that new technologies should play in them.
- This summer, talks over a potential consensus position between the Dutch government and the national farmers’ union collapsed in failure.
- The clash between the continent’s green movement and its agricultural industry is building steam, with the EU’s flagship conservation law barely squeaking through parliament in June.
In the Netherlands, pitchforks fly for an empire of cows
- In response to a court ruling, the Dutch government announced in 2022 that it would aim to halve emissions of nitrogen from livestock like cows, pigs, and chickens.
- The announcement enraged farmers in the country and sparked a massive protest movement that upended Dutch politics.
- For years, farmers in the Netherlands were encouraged to produce more milk, eggs, and cheese to meet Dutch export targets.
- The sudden u-turn and subsequent backlash gave rise to a new political party in the Netherlands, the Farmers-Citizens Movement, which swept provincial elections in March.
How manure blew up the Netherlands
- The Netherlands is one of the smallest countries in Europe, but also one of its biggest food producers and exporters, thanks to a wildly successful intensive agriculture sector.
- With the highest density of livestock in Europe, the Netherlands has been in the throes of a years-long crisis over nitrogen emissions from manure, which ecologists say are destroying the country’s ecosystems.
- When the Dutch government announced plans to buy out farms close to nature reserves and cut the country’s livestock herd by as much as one-third, farmers revolted, staging massive demonstrations and destabilizing politics in the Netherlands.
- The “nitrogen crisis” has become a flash point in Dutch society, raising difficult questions over how to reform unsustainable food systems and offering a preview of what’s to come for other countries as well.
In Mexico’s Holbox, a natural paradise suffers from its own popularity
- The island of Holbox is part of the protected nature reserve of Yum Balam, whose lagoons, mangroves and dunes are home to threatened species such as manatees, whale sharks, turtles and horseshoe crabs.
- National and international investors have converted the white sand beaches into a tourism hotspot, with the island experiencing an unchecked construction boom in recent years, driven and protected by politicians and a legal vacuum.
- Infrastructure hasn’t kept up with the tourism development; garbage, noise and sewage have turned into environmental problems, angering locals and tourists alike, and threatening local fauna and flora.
- Scientists and activists are trying to stop the destruction but are largely ignored by both the local press and the government.
What would it cost to protect the Congo Rainforest?
- The Congo Basin holds the world’s second-largest rainforest — the majority of which is in the Democratic Republic of Congo (DRC) — playing a vital role in carbon storage and ecological services that millions of people and species rely upon.
- However, the DRC is a nation with the second-highest rate of tropical deforestation behind Brazil. Meanwhile, Gabon says it has acted to protect its forests but hasn’t reaped the promised rewards.
- International commitments to protect the Congo Rainforest are historically meager compared with what experts say is actually needed, and many of these commitments go unfulfilled.
- On this episode of Mongabay Explores the Congo Basin, we speak with experts about what’s needed to overcome hurdles to financing forest protection to benefit conservation, climate and communities: Paolo Cerutti, senior scientist and DRC unit head at the Center for International Forestry Research (CIFOR-ICRAF); Chadrack Kafuti at Ghent University; Wahida Patwa Patwa-Shah, senior regional technical specialist, UNDP Climate Hub; and Lee White, minister of water, forests, the sea and environment in Gabon.
Conservationists work to restore last remnant of a once-great Ugandan forest
- Earlier this year, conservation group Nature Uganda launched a forest restoration project aimed at restoring degraded areas and reducing illegal harvesting of forest products in Mabira Central Forest Reserve.
- A remnant of a much larger forest ecosystem, Mabira is home to 300 bird species, 23 reptile species, and 360 different species of plants.
- A community forest management scheme has successfully engaged nearby communities in self-regulating use of forest resources, but delays in renewing the scheme threaten that progress.
- “When we enter these agreements,” says one community leader, “we promote the sense of ownership so that we can share the roles of making the forest available and managing it sustainably.”
Communities not the true threat to Mabira Forest: Q&A with Ugandan conservationist Achilles Byaruhanga
- Mabira is a surviving fragment of lowland forest that’s now an important refuge for a diverse range of animals and plants in central Uganda.
- The NGO Nature Uganda, led by Achilles Byaruhanga, is working with communities and government agencies to preserve and restore degraded sections of the forest reserve.
- Having seen off a government plan to clear a third of the forest to grow sugarcane, Byaruhanga says community use of Mabira is not necessarily a threat.
- By supporting alternative income activities that replace commercial harvesting of firewood and other forest products for sale in nearby Kampala, and helping local communities reduce their own demand for wood, Byaruhanga says the forest can be preserved.
Oil and gas exploration threatens Bolivian Chaco water supply
- Aguaragüe National Park is suffering from environmental damage caused by hydrocarbon exploration, the activities of which have been carried out for more than a century. In 2017, a study conducted by the Bolivian government and the European Union identified five high-risk environmental liabilities for the population, for which there is still no official information regarding remedial measures.
- There are at least 60 oil wells in this protected natural area, most of which are not closed, according to Jorge Campanini, a researcher at the Bolivian Documentation and Information Center (CEDIB).
- Per information from the Ministry of the Environment and Water, there are seven environmental liabilities and 94 oil wells in seven protected areas in Bolivia. No information was provided on the situation in the rest of the country.
In the chain of species extinctions, AI can predict the next link to break
- Scientists at Flinders University in Australia have developed a machine-learning model that predicts which species are at risk of extinction if another species is removed from an ecosystem or an invasive one is introduced.
- Trained on data on how species interact with each other, the model could serve to alert conservation managers on which vulnerable species to focus on, the developers say.
- They tested the model successfully in Australia’s Simpson Desert, where it accurately predicted which species invasive foxes and cats preyed on.
- However, the shortage of data on species interactions, along with the possible biases that arise, are gaps that still need to be filled in the model.
From debt to diversity: A journey of rewilding, carbon capture and hope
- Rewilding has transformed an English estate from a debt-ridden, conventional farm to a profitable haven of biodiversity.
- A study also shows that the rewilded farmland at Knepp absorbs more carbon dioxide than conventional farms, providing hope for climate change mitigation and soil restoration.
- The U.K. is transitioning to a new environmental land management framework offering incentives for practices that restore soil health and biodiversity, but private investment is still needed to bridge the funding gap.
- Nature restoration investment mechanisms to attract private investment are being developed using Knepp data and government funding.
Machine learning helps researchers identify underground fungal networks
- Researchers are using remote-sensing technology and machine-learning algorithms to map and predict the presence of mycorrhizal fungi in ecosystems around the world.
- The Society for the Protection of Underground Networks (SPUN) is an initiative that aims to map the distribution of fungal networks to spread awareness and advocate for their protection.
- Mycorrhizal fungi form symbiotic relationships with plants, serving as a vital interface for transferring water and nutrients from the soil while also storing massive amounts of carbon underground.
- SPUN is also working to provide financial and technical support to researchers and local communities to help them map fungal networks in their home countries.
Drought cycles erode tropics’ ability to absorb CO₂, study finds
- A recent study finds that tropical carbon sinks have become increasingly vulnerable to water scarcity since 1960, and are consequently less able to absorb carbon dioxide.
- These findings suggest that tropical ecosystems are less resilient to climate change than previously thought.
- While the study doesn’t necessarily make projections for the future, the findings suggest that an acceleration of climate change, which is very likely to bring more drought, could further limit the ability of tropical ecosystems to absorb carbon dioxide, which, in turn, would worsen climate change.
Scientists: Fishing boats compete with whales and penguins for Antarctic krill
- Scientists and campaigners recently documented huge krill fishing vessels plowing through pods of whales feeding in Antarctic waters, a permitted practice they say deprives the whales of food.
- As Antarctic waters warm due to climate change, krill numbers are declining, stressing wildlife that rely on the small crustaceans at the bottom of the food chain.
- The intergovernmental body in charge of regulating the krill fishery, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), has taken specific steps to protect penguins and seals but not whales.
- At the same time, CCAMLR has stalled on the establishment of new marine protected areas and the adoption of new conservation measures. A special meeting to advance protected areas concluded June 23 with no progress.
Sharks deserve our appreciation and protection (commentary)
- Shark Awareness Day is celebrated on July 14 every year: though widely feared and sometimes vilified, sharks actually play a key role in ocean health and are rarely a threat to humans.
- “We must all take action to protect sharks, and raising awareness and educating others about the importance of sharks is a great spot to start,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Timber harvests to meet global wood demand will bring soaring emissions: Study
- At a time when the world desperately needs to reduce its carbon emissions, global timber harvests to meet soaring demand for wood products — including paper and biomass for energy — could produce more than 10% of total global carbon emissions over coming decades, a new groundbreaking study finds.
- Global wood consumption could grow by 54% between 2010 and 2050, creating a demand for timber that would result in a “clear-cut equivalent” in area roughly the size of the continental U.S., adding 3.5 to 4.2 gigatons of carbon dioxide to the atmosphere annually for years to come.
- The study scientists warn that flawed national climate policies and faulty carbon accounting are failing to accurately forecast these potential carbon emissions resulting from the cutting of natural forests.
- The researchers point out that less natural forests need to be cut to meet the rising global demand for wood products. That demand could partially be met by increasing wood production in already existing plantation forests.
S. Africa to purge bird-eating mice from key albatross breeding island
- Non-native house mice arrived on Marion Island in the southern Indian Ocean two centuries ago, when the island was a stopping-off point for sealing ships.
- Their population has exploded recently, as temperatures warm and summers lengthen. With more mouths to feed, they’ve gutted their main food source — insects — and are now feeding on seabird chicks and adults.
- While mouse attacks on seabirds remain low and their impact on nesting or breeding success isn’t known yet, conservationists nevertheless see them as a serious and growing threat.
- Now the South African government is planning a rodent eradication program for mid-2025 that will be the largest of its kind on a sub-Antarctic island.
Tested by COVID and war, an Indigenous conservation system in Ethiopia prevails
- For more than 400 years, communities in the Guassa grasslands of Ethiopia’s central highlands have practiced a sustainable system for managing the area’s natural resources.
- The system’s robustness was severely tested from 2020 with the one-two punch of COVID-19 and the Tigray war, but held strong.
- Threats to the grassland persist, however, from a growing population and road projects, which the community hopes to address through ecotourism initiatives as an alternative source of income.
- The Guassa Community Conservation Area is home to rare plant and wildlife species such as gelada baboons, Ethiopian wolves, and the versatile guassa grass that’s a central part of community life.
Air pollution sensors found to store crucial biodiversity data
- A team of scientists have discovered that two air quality monitoring stations in the U.K. also collected DNA samples that could benefit biodiversity monitoring.
- Scientists analyzed DNA samples trapped in the two air pollution sensors and identified 180 taxa of mammals, plants, birds and invertebrates.
- The findings signal the presence of a trove of biodiversity data hidden in air pollution sensors around the world.
- The sampling and analysis of airborne DNA is a relatively new methodology to survey biodiversity; experts say further studies are required to determine its wider applications.
Volunteers, First Nations work to bring back a disappearing oak prairie
- The rain-shadow regions of North America’s Pacific Northwest, stretching from British Columbia to Oregon, are home to a unique carbon-rich oak-prairie ecosystem dominated by Garry oaks and several species of grasses and shrubs, including endemic plants.
- The ecosystem also holds a special significance in the way of life for the Indigenous peoples in the region, who have stewarded it for millennia and depended on it for food.
- In the past few centuries, however, rapid urbanization, agricultural expansion, development along the coast and proliferation of invasive plants have destroyed more than 95% of the ecosystem, pushing it toward near-extinction.
- Communities, partnering with different national and regional agencies, First Nations and nonprofits, are working to restore and preserve the remnants using various strategies, many of which have borne fruit.
A powerful U.S. political family is behind a copper mine in the Colombian rainforest
- Two members of the Sununu family, a powerful U.S. Republican Party dynasty, are among the directors or shareholders of Libero Copper, a copper mine promoted in the Colombian Amazon. John H. Sununu, a powerful former governor of New Hampshire and former White House chief of staff to George Bush Sr. is one of its ultimate beneficial owners. His son Michael Sununu sits on the mining company’s board of directors.
- The government sees the mine as strategic to the clean energy transition by providing copper used in electric cars, solar panels and wind turbines. However, Libero’s two Sununus are known in the U.S. as skeptics of the scientific consensus that climate change is man-made, raising questions now that they are at the helm of a ‘green energy’ mining project in the midst of such a fragile and strategic biome as the Amazon rainforest.
- In order for Libero Copper’s project to become a reality, the company says it requires not only an exploitation license and an environmental permit from the Colombian government, but also that authorities lift the protected area status of part of the deposit. The reason is that one-fifth of the copper that the mining company seeks to extract is buried under a protected natural area known as a nationally protected forest reserve.
- The prospect of this mine is a cause of concern for the Indigenous communities in its area of influence, especially the Inga reservation of Condagua to the north and Kamentsá Biya of Sibundoy to the west, who fear disruption of critical waterways and the destruction of their territory.
China’s Qinghai-Tibet ecosystem legislation is a landmark, but for whom? (commentary)
- The Qinghai-Tibet Plateau Act is China’s first legislative vision for the environmental protection of the Tibetan plateau and its surroundings, covering an area larger than western Europe.
- Hailed as a legislative landmark by state-sponsored media, its effects could ripple far beyond China’s borders, with likely effects on international rivers such as the Brahmaputra, Indus, Mekong, Irrawaddy and Salween, which flow from the Tibetan plateau.
- In a new commentary, a conservation biologist concerned about the QTP ecosystem explains how its 63 articles cover a nearly panoramic selection of topics, making the act a good starting point for understanding the major environmental issues of the region.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Award-winning community group in Sumatra cleans up lake
- A group of locals have since 2013 tried to clean up the trash pooling in Lake Sipin in the Sumatran province of Jambi.
- Their efforts have received national attention, with their leader, Leni Haini, awarded the country’s highest environmental award in 2022 by the government.
- Indonesia has announced a plan to restore 15 lakes (Sipin isn’t included) across the country by 2024, citing their high degree of degradation, chiefly sedimentation, which has resulted in their rapid shrinking and a decline in the biodiversity they host.
- These lakes are crucial in supporting the livelihoods of millions of Indonesians, serving as a source of freshwater, a form of flood control, and a site for fish-farming and tourism.
Woodpeckers for fire recovery? A new online tool tells you how
- An online tool maps and predicts the presence of black-backed woodpeckers (Picoides arcticus) in newly burned forests in California.
- The tool aims to aid fire managers in incorporating the protection of these birds into their efforts to revive burned forests.
- Black-backed woodpeckers thrive in the diverse ecosystem left behind by wildfires, but fire suppression efforts and salvage logging often disturb their habitats.
- Through the case study of black-backed woodpeckers, the tool aims to illustrate how wildlife conservation and pyrodiversity (the variation in which fires burn landscapes) should be incorporated into fire management efforts around the world.
Forest behind bars: Logging network operating out of Cambodian prison in the Cardamoms
- A Mongabay investigation has uncovered a logging operation being run out of Koh Kong provincial prison that gets its timber from the site of a new hydropower dam being built in Thma Bang.
- Old-growth forest in Central Cardamom Mountains National Park is being cleared to make way for the Stung Tatai Leu hydropower dam, but the environmental impacts remain opaque.
- NGOs and the Ministry of Environment provide minimal oversight to prevent illegal loggers from exploiting the project site, and former loggers detailed how bribes facilitate the illicit timber trade.
- Prison officials maintained that the timber is used in a skills development program, but former inmates alleged that officials have been exploiting prison labor to craft luxury furniture.
Don’t destroy Earth on the way to Mars (commentary)
- SpaceX CEO Elon Musk’s drive for humanity to become a “multi-planetary species” comes with great irony if this very activity accelerates degradation of the Earth.
- Last month’s “rapid unscheduled disassembly” of a SpaceX rocket rained debris and possibly other toxics on a rich estuary adjacent to the launch pad on the Gulf of Mexico.
- “We cannot destroy our most special places on Earth in our heady rush to Mars,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Fewer migratory birds stopping at key Bangladesh wetland amid human disturbances
- Numbers of most species of migratory waterbirds in Bangladesh’s Tanguar Haor wetland, a key stopping point, have fallen over the past 15 years, a new study shows.
- The cause of the decline isn’t fully known yet, researchers say, but it’s clear that human activity has impacted the wetland, with 40% of the basin’s original area converted to farmland and settlements in just 30 years.
- The study recommends prioritizing conservation at two of the permanent waterbodies, or beels, in the Tanguar Haor complex, citing the high abundance and diversity of the birds that stop there.
- Tanguar Haor is the second Ramsar site in Bangladesh, after the Sundarbans mangrove forest, and accounted for nearly half of the more than 1.2 million waterbirds recorded in the country between 2008 and 2015.
Spamming streams with hatchery salmon can disrupt ecosystems, study finds
- In a new study, researchers found that releasing hatchery-bred native masu salmon into freshwater streams in Hokkaido, Japan, destabilized the local ecosystems.
- Overall, the study found that the total number of fish, and number of different species, both declined in the long term due to greater competition for resources like food and preferred feeding spots.
- Masu salmon populations also did not increase in the long term, the research found.
- With hatchery releases increasing in many areas — and for many species — the findings add to the ongoing debate over their wider effects on wild fish populations.
Hawaiian communities restore Indigenous conservation, from mountains to sea
- In Hawai’i, an Indigenous stewardship and conservation system known as ahupua’a is slowly being revived on a mountain-to-sea scale in partnership with U.S. government agencies.
- Three Indigenous communities that have successfully reintroduced the ahupua’a system are seeing some conservation successes, such as a 310% increase in the biomass of surgeonfish and an increase in the Bluespine unicornfish (Naso unicornis) population.
- The inclusion of Indigenous Hawaiian conservation, social and spiritual values, like Aloha kekahi i kekahi, have been key to building these conservation areas and forming better working relations with the government.
Colombia: Scientists explore remote seamounts to protect hammerhead sharks
- Since 2000, the Malpelo and Other Marine Ecosystems Foundation has conducted 40 expeditions on and around Malpelo Island, a rocky outpost about 500 kilometers (310 miles) off Colombia’s Pacific coast.
- These expeditions have allowed the foundation to gather information about the area’s population of scalloped hammerhead sharks (Sphyrna lewini) and to discover this critically endangered species’ breeding areas.
- They’ve also influenced the expansion of the Malpelo Fauna and Flora Sanctuary and UNESCO’s declaration of it as a World Heritage Site.
- Malpelo Foundation researchers hope their new expeditions to the area’s seamounts, which form a vital corridor for migratory species, will inform the ongoing fight against illegal fishing that threatens the hammerheads and other marine fauna.
Saving forests to protect coastal ecosystems: Japan sets historic example
- For hundreds of years, the island nation of Japan has seen various examples of efforts to conserve its coastal ecosystems, vital to its fisheries.
- An 1897 law created protection forests to conserve a variety of ecosystem services. “Fish forests,” one type of protection forest, conserve watershed woodlands and offer benefits to coastal fisheries, including shade, soil erosion reduction, and the provision of nutrients.
- Beginning in the late 1980s, fishers across Japan started planting trees in coastal watersheds that feed into their fishing grounds, helping launch the nation’s environmental movement. Although the fishers felt from experience that healthy forests contribute to healthy seas, science for many years offered little evidence.
- New research using environmental DNA metabarcoding analysis confirms that greater forest cover in Japan’s watersheds contributes to a greater number of vulnerable coastal fish species. Lessons learned via Japan’s protection and fish forests could benefit nations the world over as the environmental crisis deepens.
Kelp forests contribute $500 billion to global economy, study shows
- New research suggests that kelp forests generate up to $562 billion each year by boosting fisheries productivity, removing harmful nutrients from seawater, and sequestering carbon dioxide.
- The findings suggest that kelp forests are about three times more valuable than previously believed, contributing the equivalent of Sweden’s entire GDP to the global economy.
- However, experts say that kelp forests are generally overlooked and undervalued, and that many of these ecosystems are under threat worldwide.
A mountain of gold: Mining titles threaten Indigenous lands in Guainía, Colombia
- A potential gold rush is awaiting in the surroundings of the Mavicure Hill and the Fluvial Star of Inírida, two of Colombia’s particular ecosystems. Authorities approved 13 proposals for mining concession contracts for extracting gold and gold concentrates.
- Mongabay Latam and Vorágine visited the Indigenous communities surrounding the Fluvial Star of Inírida. Their residents now live in a climate of uncertainty because of the promises of a better future based on mining. There is simultaneously ignorance and enthusiasm about the prospect of new jobs.
- Mining has not started yet in the area, and there is already division surrounding this issue in the Remanso Chorrobocón Indigenous Reserve. Some people view mining positively, but there are also complaints that the mining titles are being managed in the name of the Indigenous people, even though they have not been consulted.
Home to rare corals, a Chilean fjord declines in spite of protection
- The Comau Fjord, in the Chilean region of Patagonia, is one of the only sites in the world where the cold-water coral Desmophyllum dianthus lives just 5 meters (16 feet) below the sea surface.
- The easy access to these animals, which elsewhere live at extreme depths, motivated a group of scientists to study them.
- Their research brought new information to light about the corals’ biology and also revealed that the Comau Fjord is at serious risk.
Counterintuitive conservation: Fire boosts aquatic crustaceans in U.S. savannas
- In an interesting twist, two kinds of rare American freshwater crustaceans have been found to thrive after prescribed burns in their habitats.
- Populations of vernal pool fairy shrimp in Oregon and several species of threatened crayfish on the Gulf Coast increased after the removal of invasive plants, woody shrubs and trees from their habitats using fire or mechanical means.
- Fairy shrimp populations were shown to increase more than fivefold following habitat treatments that featured fire, while speckled burrowing crayfish also responded positively following fires set to favor nesting of sandhill cranes (whose own population has soared since).
- Both areas are savanna ecosystems that have relied on frequent fires over millennia — whether naturally occurring or intentionally set by Indigenous peoples — to maintain the open habitats to which myriad organisms have adapted.
Indigenous women in Colombia protect rich Amazonian wetland from overfishing
- Dozens of Indigenous women in Colombia’s Amazon are monitoring, managing, raising awareness and restoring a wetland ecosystem impacted by overfishing.
- After partnering with environmental organizations to establish a fishing agreement in the area, they have witnessed the increase and recovery of fish species such as sardines, catfish and the pirarucu (Arapaima gigas).
- The wetland area of Lake Tarapoto, located in the department of Amazonas in southern Colombia, provides a habitat for numerous aquatic animals and supports the livelihoods of 22 Indigenous communities.
Bankrolling biodiversity: How are private philanthropists investing in nature?
- A Mongabay analysis of the largest-ever private philanthropic campaign for biodiversity conservation has found about a quarter of the pledged $5 billion has already been allocated.
- The Protecting Our Planet (POP) campaign was launched in late 2021 ahead of the COP15 conference in Montreal. The POP group includes foundations representing some of the richest people on Earth.
- Critics of the scheme have called for greater transparency in the use of private funds for protected areas conservation, such as the creation of a charter of principles and commitments, or compliance framework, to mitigate negative impacts.
Rewilding animals could be key for climate: Report
- A new report published in Nature Climate Change suggests that trophic rewilding, or restoring and protecting the functional roles of animals in ecosystems, is an overlooked climate solution.
- Reintroducing just nine species or groups of species (including African forest elephants, American bison, fish, gray wolves, musk oxen, sea otters, sharks, whales and wildebeest) would help limit global warming to less than the 1.5°C (2.7°F) threshold set by the Paris Agreement, according to the report.
- Animals play a significant role in how much carbon plants, soil and sediments can capture, as they redistribute seeds and nutrients and disturb soil through digging, trampling, and nest-building.
- The report emphasizes the need for a change in mindset within science and policy to take advantage of the vast potential of wildlife, while working closely with local communities to address social issues that can affect conservation efforts.
‘Impact assessments need a shake-up’: Q&A with Georgine Kengne & Morgan Hauptfleisch
- Environmental and social impact assessments as they’re implemented in development projects across Africa need a “shake-up” to ensure they’re fit for purpose, experts say.
- Georgine Kengne, from the WoMin African Alliance, says the ideal ESIA process would be one in which “the government and the mining company are not just colluding to make profits.”
- Morgan Hauptfleisch, a professor of nature conservation in Namibia, says the fundamental problem is that ESIAs and other safeguards can simply be ignored with little consequence other than fines that the companies just budget for anyway.
- Mongabay spoke with both Kengne and Hauptfleisch about ESIAs, community participation, and the underused tool that is the strategic environmental assessment (SEA).
Blended finance can supercharge conservation (commentary)
- Bringing together donors, nations, UN agencies, foundations, NGOs, and private investors, ‘blended finance’ can align private investment with public monies to fund conservation.
- A new commentary by the founding chairman of the world’s largest such mechanism focused on ocean conservation — the Global Fund for Coral Reefs — argues that it can serve as a model for others working to reverse biodiversity loss.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Deforestation could pose disease threat to Amazon’s white-lipped peccaries
- White-lipped peccaries are vital ecosystem engineers and an important source of food for people living in the Amazon.
- Deforestation has reduced their habitat and, in addition, researchers highlight that disease is an understudied factor in their conservation.
- Scientists say it could represent an additional threat to an already vulnerable species, as continuing deforestation and expanding agricultural frontiers can bring greater contact between domestic animals and wildlife, potentially leading to spillover events.
Biodiversity conservation needs a more ecological context and transformational concept (commentary)
- Halting biodiversity loss is one of the great challenges of the 21st century, and if we want international conservation policies that work, we need to urgently re-evaluate how we think ecosystems work, argue the authors of this op-ed.
- We can do so by measuring some core processes of the many unique ecosystems, by employing factors like proxy measuments and analyzing the local ecological and environmental processes taking place in an ecosystem.
- Nations must move away from simplistic policy based on a desire for general rules and instead embrace the complexity of their ecosystems, with the help of researchers and scientists. “Only by protecting this complexity can we protect our diversity into a changing future.”
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
For key Bangladesh wetland, bid for Ramsar status is no guarantee of protection
- Bangladesh has proposed designating a third Ramsar site in the country, but the current state of its two other important wetland ecosystems suggests such a designation won’t be of much protection.
- The Sundarbans, the world’s biggest mangrove forest, and Tanguar Haor, a freshwater swamp forest, have been severely degraded by deforestation, hunting of wildlife and fish, overexploitation of natural resources, and water pollution.
- Hakaluki Haor, the largest marsh wetland ecosystem in South Asia, which the government wants designated a Ramsar site, is already facing similar threats.
- “The problem is, the government does nothing after the recognition. They completely fail to take necessary measures, in the interest of vested quarters in the government,” says environmental lawyer Syeda Rizwana Hasan.
Saving Masungi, a last green corridor of the Philippines: Q&A with Ann Dumaliang
- The Masungi Georeserve is an important geological region about 30 miles from Manila, within a watershed and conservation area that is home to more than 400 species of flora and fauna, several of which are rare and threatened.
- Ann Dumaliang is a co-founder of the foundation that manages conservation and geotourism in the reserve, which is threatened by illegal quarrying, logging and development.
- Masungi’s rangers have faced violent attacks in recent months, but Dumaliang, her family and colleagues are working with numerous organizations and individuals to reforest and preserve the area.
Ukrainian ecologists say nature will suffer no matter war’s result (commentary)
- “As Ukrainian ecologists, we are constantly reminded of the extent to which war itself is at war with nature.”
- In a new commentary, two scientists linked to the Ukraine War Environmental Consequences Work Group share their views on the current and future ecological restoration work that will be needed in their country.
- Scientists and communicators linked to the group also hail from Russia and Belarus, countries which are engaged in the conflict against Ukraine: this is unusual and touching, the authors say. “The project has a huge democratic weight: when we’re trying to do the right thing for people and for nature, nationality doesn’t matter.”
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
The dark side of light: Coastal urban lighting threatens marine life, study shows
- A new study finds that artificial lights in coastal megacities have come to outshine the moon for most of the year, putting marine species at risk.
- The researchers say that light pollution impacts on marine ecosystems are difficult to assess compared to other pollutants, as levels of light underwater are not only hard to detect with current instruments, but the spectrum and magnitude can change with tides and water clarity.
- Experts note that artificial light pollution needs to be addressed through mitigation plans aimed at cutting the use, duration and intensity of urban lighting, especially considering the popularity of LEDs, whose blue light penetrates the sea deeper than orange lights.
Understanding reptile intelligence can aid conservation and safeguard ecosystems (commentary)
- Reptile intelligence has long been considered inferior to that of birds and mammals. But recent studies in reptile cognition show reptiles have a profound understanding of their environment.
- Reptiles’ understanding of their surroundings and their evolution of learning can play a part in biodiversity conservation and ecosystem service provisioning, especially on agricultural lands.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Protecting canids from planet-wide threats offers ecological opportunities
- Five species within the Canidae family are considered endangered. These species, while found far apart in North and South America, Asia and Africa, often share similar threats, including habitat loss, persecution, disease and climate change.
- For some at-risk canid species, loss of prey, particularly due to snaring, is a significant concern that can also exacerbate human-wildlife conflict. Ecosystem-level conservation that protects prey species populations is required to protect canids and other carnivore species, experts say.
- Conservationists and researchers emphasize that canids play important roles in maintaining the habitats in which they live. That makes protecting these predators key to restoring and maintaining functional ecosystems.
- In the face of widespread global biodiversity loss, some canid reintroductions are taking place and proving successful. These rewilding efforts are offering evidence of the importance of canids to healthy ecosystems and to reducing various ecosystem-wide threats, even potentially helping curb climate change.
Island conservation should focus on land-sea links for most impact, paper says
- A new perspective piece in PNAS explores the idea that people, wildlife and the environment of islands thrive when conservation efforts focus on restoring both the land and sea together.
- One way to restore land-sea connections on islands is to eradicate invasive species, such as rats, which can harm native island species like seabirds and crabs.
- Research has shown that terrestrial and marine ecosystems reap benefits when invasive species are eliminated from islands.
Dollars and chainsaws: Can timber production help fund global reforestation?
- As global reforestation commitments grow, how will companies, governments and communities pay to restore forest ecosystems and help sequester carbon over the long-term?
- One option: Grow and sell timber on the same plots of land where reforestation work is underway, as exemplified by pioneering restoration projects in Brazil’s Atlantic Forest, where a single harvest of fast-growing eucalyptus grows up amid restored native trees. Eucalyptus sales then help pay for long-term restoration.
- Another approach is to concurrently grow tree plantations and forest restorations on separate, often adjacent, plots of land, with a large portion of the profits from timber harvests going to support the long-term management of the reforestation projects.
- But some scientists and forest advocates worry that projects or businesses that become overreliant on timber revenues to finance restoration could undermine an initiative’s environmental benefits, and lock in unintended harvesting within native ecosystems. Experts ask: Can we truly pay for new trees by cutting others down?
Zero-deforestation commitments can push agriculture to other rich biomes, study warns
- Zero-deforestation commitments (ZDCs) made by the palm oil industry and adopted by producers of other crops as well focus on preserving rainforests, while leaving other biomes unprotected.
- New research by the University of York shows that even if current ZDCs are fully met, around 167 million hectares of mostly tropical grassy and dry forest would remain open for agricultural expansion.
- Often confused with degraded areas that emerge after clearing the rainforest, those biomes are actually rich and biodiverse and also play a role in storing and capturing carbon.
- New EU legislation approved in December adds extra protection for rainforests, but could push even more agricultural production to other biomes, most of them in Africa and Latin America.
Brazil’s Pantanal is at risk of collapse, scientists say
- Though the Pantanal is 93% privately owned, this vast Brazilian tropical wetland remains a stronghold for jaguars and untold other species, and connects animals with the Amazon, Cerrado and other biomes.
- A confluence of human activities in Brazil and worldwide — including deforestation and climate change — are heating and drying this watery landscape, threatening the entire ecosystem with drought, wildfires and habitat loss.
- Now, a plan to dredge and straighten the Paraguay River that feeds the Pantanal could serve as the death knell for this vast wetland ecosystem.
- There’s hope that president-elect Luiz Inácio Lula da Silva, who campaigned on an environmental platform, will initiate stewardship that stops Pantanal deforestation and the waterway project, helping curb greenhouse gas emissions.
Mongabay’s Conservation Potential series investigates: Where do we need to protect biodiversity?
- Leaders and decision-makers are recognizing the urgency of protecting the world’s remaining biodiversity, but investing in conservation requires these actors have access to reliable and actionable information about ongoing conservation projects.
- Mongabay is launching a series of stories called “Conservation Potential,” in which we investigate conservation efforts in high-priority biodiversity areas in tropical forests across the globe.
- To introduce this series, we look at what some experts say about where to prioritize biodiversity conservation, what are some popular approaches to conservation, and what makes conservation projects successful.
- Approaches to conservation vary according to priorities, and there are even debates over what it means to protect biodiversity. This introduction is not meant to be an exhaustive review of the dozens of plans and schemes for preserving biodiversity, but it offers a conceptual starting point for our series.
Tech companies work to make fishing, aquaculture more sustainable
- Several companies around the world are developing technology to make fishing and aquaculture more sustainable.
- These include the use of artificial intelligence to identify non-native species that disrupt marine food webs and the fisheries they support, and lights that attempt to attract only target species to fishing nets in a bid to reduce the capture of non-targeted species.
- With the rapidly increasing global population underscoring the need to source protein more sustainably, experts say it’s urgent to find ways to make fishing less damaging and more productive.
Counterintuitive: Large wild herbivores may help slow climate change
- Large animals, especially herbivores such as elephants, are often seen as being destructive of vegetation, so are not thought of as a nature-based climate solution. Scientists are proving otherwise.
- By removing living and dead plants, large animals dispose of material that may fuel wildfires, which can add large amounts of carbon to the atmosphere; by consuming vegetation and excreting dung, large animals may improve the availability of nutrients to plants and support the storage of carbon in vegetation and soil.
- By creating gaps in the vegetation and dispersing seeds, large animals create diverse ecosystems with plenty of opportunities for a variety of plants to grow, making ecosystems more resilient and better able to deal with climate change.
- By nibbling down polar region shrubs and trampling snow, large animals help maintain permafrost, helping prevent the release of carbon to the atmosphere.
Climate change is hammering insects — in the tropics and everywhere else: Scientists
- A new review paper finds that climate change is pounding insects in a wide variety of ways all over the world.
- Because insects are so sensitive to temperature change, climate change is impacting them directly, including potentially decreasing their ability to breed.
- But climate change is also causing insects to change their behavior as it shifts seasonal beginnings and ends, risking that insects will act out of sync with the rest of the environment on which they depend. Climate change-intensified drought, extreme precipitation, lengthening heat waves, and fires are also harming insects.
- The best way to protect insects? Combat climate change and safeguard micro-habitats.
Peat on land and kelp at sea as Argentina protects tip of Tierra del Fuego
- Argentinian legislators recently approved a law to permanently protect the Mitre Peninsula at the tip of South America, which harbors vast peatlands and kelp forests that host an assortment of species.
- The Mitre Peninsula is thought to hold about 84% of Argentina’s peatlands, which are known to sequester about 315 million metric tons of carbon dioxide, roughly equivalent to three years of emissions in Argentina.
- The region also holds more than 30% of the world’s kelp forests, another key store of carbon.
Animating the Carbon Cycle: Earth’s animals vital allies in CO2 storage
- The idea of animating the carbon cycle (ACC) is relatively new. The concept champions the role that healthy populations of wild animals, both terrestrial and marine, can play in boosting the ability of ecosystems to store carbon, helping the planet stay within 1.5°C (2.7°F) of temperature rise over pre-industrial levels.
- But for ACC to be fully effective, humanity needs to preserve and protect intact nature. We also need to rebuild populations of wild animals, including apex predators such as wolves, large herds of herbivores, and invertebrates such as pollinators. By doing so we can help rebalance the functions of natural systems.
- ACC puts the spotlight on oceans too, and the role animals there can play in sequestering carbon. It calls for greater protection of the seas and marine life, allowing whale populations to grow, and protecting mesopelagic fish — the largest group of vertebrates on the planet — from overfishing.
- By looking at the bigger picture of animal-plant-ecosystem relationships, and based on the growing popularity of nature-based climate solutions, scientists believe that now is the time for the wider conservation and rewilding movements to embrace ACC to help animals fulfill their vital roles in the carbon cycle.
Will shipping noise nudge Africa’s only penguin toward extinction?
- The African penguin (Spheniscus demersus) is expected to go extinct in the wild in just over a decade, largely due to a lack of sardines, their main food.
- A colony in South Africa’s busy Algoa Bay is suffering a population crash that researchers say coincides with the introduction of ship-to-ship refueling services that have made the bay one of the noisiest in the world.
- They say theirs is the first study showing a correlation between underwater noise pollution and a seabird collapse.
- Current studies are investigating whether the ship noise is interfering with the penguins’ foraging behavior and their ability to find fish.
Alleged macaque-smuggling ring exposed as U.S. indicts Cambodian officials
- U.S. federal prosecutors have charged eight people, including two Cambodian forestry officials, for their alleged involvement in an international ring smuggling endangered long-tailed macaques.
- The indictment alleges forestry officials colluded with Hong Kong-based biomedical firm Vanny Bio Research to procure macaques from the wild and create export permits falsely listing them as captive-bred animals.
- One of the officials charged was arrested in New York City on Nov. 16, en route to Panama for an international summit focused on regulating the global trade in wildlife.
- This story was supported by the Pulitzer Center’s Rainforest Investigations Network where Gerald Flynn is a fellow.
Breeding success raises hopes for future of endangered African penguin
- Two African penguin chicks have hatched at a nature reserve in South Africa where conservationists have been working for years to entice the endangered birds to breed.
- The colony was abandoned more than 10 years ago after a caracal killed a number of penguins.
- The recent hatching comes at a time when survival prospects for Africa’s only resident penguin species look grim, due mainly to declining food stocks.
- But encouraging new colonies at sites close to abundant food sources could help to bring the species back from the brink.
Rat killers in paradise: An eradication program remakes a tropical atoll
- Like many islands around the world, Tetiaroa Atoll in French Polynesia has been overrun by rats and other invasive species that profoundly affect its terrestrial and marine ecosystems.
- In July, the paradisiacal 12-island atoll was declared rat-free after years of concerted efforts to wipe out the predators.
- Scientists have been studying the atoll’s plants, seabirds, insects, lizards, crabs, coral and algae, establishing a uniquely comprehensive ecological baseline to better understand how the rat eradication will affect the atoll — and others like it.
Negotiations to conserve Antarctic Ocean end in stalemate on many issues
- The 41st annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with conserving marine life in the Southern Ocean and managing fisheries there, ended Nov. 4 with little progress made on several key issues.
- In 2009 CCAMLR committed to creating a network of marine protected areas to preserve Antarctic ecosystems. It established one that year and another in 2016, but since then China and Russia have repeatedly blocked the creation of additional protected areas, as well as other conservation-related measures.
- The commission also failed to reach the consensus required to enact new regulations for the krill and toothfish fisheries, or to protect a vast nesting area for icefish discovered earlier this year.
- CCAMLR members did agree to designate eight new vulnerable marine ecosystems, areas home to slow-growing organisms such as corals, sponges, brittle stars and feather stars that are now permanently protected from bottom fishing.
Who decides on ‘priorities’ for ecosystem restoration?
- A set of maps from research published in 2020 in the journal Nature suggested that restoring ecosystems in “priority areas” offered a cheap and effective way to slow climate change and stem the global loss of species.
- Soon after the study’s release, however, researchers from around the world raised concerns about the areas identified by the study, whether the biodiversity- and climate-related gains would be as substantial as the authors claimed, and how decision-makers might use the maps to guide policy.
- The study aimed to point out optimal spots for restoration based on the biggest boost they could provide to avoid the extinction of species and sequester the most carbon at the lowest costs. But, the authors wrote, the study did not consider “socio-economic issues,” and the maps were not intended to directly inform local implementation.
- The study’s critics say that, in spite of the authors’ intentions, investors and policymakers could use the maps in ways that might not consider the impacts on local communities.
Deep dive uncovers previously unknown underwater ecosystem in Maldives
- Scientists recently identified a previously undiscovered marine ecosystem in the waters around the Maldives, known as the “trapping zone,” about 500 meters (about 1,600 feet) below the surface.
- The researchers say the trapping zone refers to a region of subsea vertical cliffs and shelving terraces that “trap” small, migrating mesopelagic organisms, which attract pelagic predators like sharks, tuna and large fish.
- Prior to this mission, very little was known about the Maldivian sea below 30 m (about 100 ft), despite the country’s total area consisting 99% of water.
- The researchers say trapping zones likely exist in the waters around other oceanic islands with similar topography, and that they’re already gathering evidence of such an ecosystem in the waters of the Chagos archipelago, south of the Maldives.
Humans are decimating wildlife, report warns ahead of U.N. biodiversity talks
- Wildlife populations tracked by scientists shrank by nearly 70%, on average, between 1970 and 2018, a recent assessment has found.
- The “Living Planet Report 2022” doesn’t monitor species loss but how much the size of 31,000 distinct populations have changed over time.
- The steepest declines occurred in Latin America and the Caribbean, where wildlife abundance declined by 94%, with freshwater fish, reptiles and amphibians being the worst affected.
- High-level talks under the U.N. Convention on Biological Diversity (CBD) will be held in Canada this December, with representatives from 196 members gathering to decide how to halt biodiversity loss by 2030.
Loss of Brazilian pines threatens Kaingáng Indigenous culture
- The decline of the Paraná pine forests in the southern region of Brazil poses serious consequences for the Kaingáng culture, which uses pine trees as an important source of food, culture and resilience.
- The ecosystem is one of the most devastated in Brazil: Only 3% of its original area remains.
- The tree occupies a noble position in the Kaingáng culture, considered the third-largest Indigenous group in Brazil, with 45,000 people living in the states of Rio Grande do Sul, Santa Catarina, Paraná and southern São Paulo.
- “Efforts to revitalize Kaingáng culture must be aligned with the resurgence of araucaria planting in the territories of the Kaingáng people,” says an Indigenous expert.
To protect the Southern Ocean, leaders must act now (commentary)
- This week in Australia, global leaders have the opportunity to protect Antarctica’s vast and biodiversity rich Southern Ocean at the annual Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) meeting.
- Emperor penguins, orcas, crabeater seals, albatross, and krill are among the species that call this region home, but the latter is a key one that plays a huge role in the health of Antarctica, since it underpins the food web.
- The commercial krill fishery produces fishmeal for pets, people and aquaculture and has become concentrated in recent years, with most of the catch taken from small, nearshore areas where wildlife feed: “We need Southern Ocean MPAs and well-designed fishery measures to effectively conserve fish populations, habitats and wildlife,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Fish-feed industry turns to krill, with unknown effects on the Antarctic ecosystem
- The Antarctic krill fishing industry has been growing in the past two decades.
- The global growth of fish farming is driving the demand for Antarctic krill as an alternative to wild fish in fish feeds, amid the depletion of many wild fish stocks.
- Independent scientists say the krill fishery could have a detrimental effect on Antarctica’s predator populations, which are also suffering from the impacts of global warming.
- The krill industry is expanding its fleet and planning to significantly increase catches in the next few years.
On the roof of the world, water is life. Or a sign of it, thanks to eDNA
- A first-of-its-kind expedition in 2019 attempted to map the biodiversity on Mount Everest by using environmental DNA, or eDNA.
- With eDNA, the team was able to detect species that would have been hard to observe visually.
- The findings aim to serve as baseline data for future expeditions that study how climate change is reshaping life on the world’s highest peak.
Examining cooperation in nature: Q&A with author Kristin Ohlson
- In her new book, “Sweet in Tooth and Claw: Stories of Generosity and Cooperation in the Natural World,” author Kristin Ohlson explores the science behind collaboration in nature.
- Her work examines research revealing that cooperation between species, and not just competition, contributes to the development and diversification of life.
- Mongabay spoke with Ohlson prior to the book’s publication.
Stamping out invasive species has successful track record on islands, study finds
- A recent study published in the journal Scientific Reports found that efforts to remove invasive vertebrates from islands were 88% successful between 1872 and 2020.
- Invasive species can be particularly devastating to delicate island ecosystems and the unique native species they harbor.
- The researchers looked at the methods, locations and target species of 1,550 eradication attempts on nearly 1,000 islands around the world.
- The authors say the results of the research provide a guide for conservation groups, scientists and countries to take on eradication projects in an effort to encourage the resurgence of native wildlife and restore ecosystems.
In Nepal, endangered tiger kills critically endangered gharial. What does it mean?
- A tiger entered the Kasara gharial breeding center in Chitwan National Park and killed three critically endangered gharials.
- The incident raised concerns that as the tiger population in Nepal increases, the animals could turn to the crocodiles for easy food.
- Conservationists, however, say that is unlikely as tigers have other animals to feed upon.
In Kathmandu, when the falcon’s away, pigeons come out to play. And poop
- Once treated as pets, Kathmandu’s pigeons have now become a menace.
- With their population growing unchecked, the birds invade homes, soil buildings, and frequently carry parasites.
- Ornithologists attribute the pigeon population boom to the decline in urban birds of prey, such as peregrine falcons that once kept pigeon numbers under control.
- The long-term solution to the problem, they say, is to identify and fix the factors that have pushed the raptors out of the city.
Biodiversity underpins all, as California is finding out the hard way
- A new episode of “Mongabay Explains” delves into the biodiversity crisis in California, which is known to be one of the most biodiverse states in the U.S., hosting about 6,500 animal species, subspecies and plants.
- California has been bearing the brunt of climate change in recent years as wildfires and drought transform the land.
- The film focuses on three species that are being negatively affected by the climate crisis: California tiger salamanders, acorn woodpeckers, and monarch butterflies.
- The filmmaker says California is the “poster child of what's happening to our ecosystems around the world.”
Jumbo task as Malawi moves 263 elephants to restock a degraded national park
- Over the last month, 263 elephants were relocated from Liwonde National Park to Kasungu National Park, both in Malawi.
- Liwonde, managed by African Parks, an NGO, hosts some 600 elephants, more than its ecosystem can support.
- Kasungu’s elephant population was previously decimated by poaching, but officials say the park is ready to host more elephants after years of anti-poaching and community engagement efforts.
First-of-its-kind freshwater mangroves discovered in Brazil’s Amazon Delta
- Researchers on an expedition in the Amazon River Delta have found mangroves growing in freshwater — a phenomenon never before documented in deltas or coastal mangroves anywhere else in the world.
- The mangroves, overlooked by previous satellite mapping efforts, increase the known area of mangroves in the region by 20%, or an additional 180 square kilometers (70 square miles).
- Mangroves are a more effective carbon sink than other types of tropical forest, with more than 8% of all carbon stocks worldwide held in Brazil’s mangroves.
- Despite their many ecosystem services, mangroves are not well protected or funded in Brazil.
EU’s anti-deforestation bill leaves out critical ecosystems, study shows
- New regulation proposed by the European Commission aims to reduce the import of commodities that cause deforestation and forest degradation abroad.
- But according to a report commissioned by the EU Greens parliament members, the narrow definition of forest and deforestation in the revised legislation would not protect ecosystems in South America where EU demand for commodities such as soy and beef create high deforestation risk.
- Soy production is not only destroying native vegetation, but also threatens the livelihoods of hundreds of Indigenous peoples and traditional communities in the Cerrado and Chaco biomes, made of grasslands, savannas and dry forests stretching down the center of South America.
- Broadening the definition of forest to include other types of wooded land, or adopting a definition based on native vegetation rather than forest, would protect much more of the Cerrado and the Chaco, and be much more effective at tackling deforestation, the report says.
Latest ‘plan for the planet’ calls for protecting 44% of land, home to 1.8b humans
- A new study says 44% of Earth’s terrestrial area needs conservation attention to halt the runaway destruction of the natural world.
- The figure is significantly higher than the goal currently under discussion as part of the global post-2020 agenda, which is to protect 30% of land and ocean by 2030.
- The area identified for protection by the new study is home to 1.8 billion people, almost a quarter of the human population.
- The study authors suggest prioritizing biologically rich regions at the highest risk of being converted for human use by 2030, most notably in Africa.
Yellowstone’s wolves defied extinction, but face new threats beyond park’s borders
- Since their reintroduction into Yellowstone National Park in the Mountain West of the United States in the 1990s, the North American gray wolf has recovered, once again taking up the mantle of a keystone species in its environment.
- But the wolf’s resurgence has raised the ire of ranchers and hunters, and new laws allowing expanded wolf hunts have sprung up across the region.
- Biologists contend that wolves play a critical role in maintaining healthy ecosystems, and data suggest that the threat to overall livestock numbers is exaggerated.
- Still, an entrenched fear, perhaps dating to humans’ earliest interactions with wolves, has helped to stir up a desire for vengeance against the species.
Rachel Carson’s ‘Silent Spring’ 60 years on: Birds still fading from the skies
- Rachel Carson’s “Silent Spring” catalyzed the modern environmental movement and sparked a ban on DDT in the U.S. and most other nations, though DDT has since been replaced by a growing number of other harmful biocides.
- Now, 60 years later, birds may face more threats than any other animal group because they live in — or migrate through — every habitat on Earth. Birds are impacted by land-use changes, pollution (ranging from pesticides to plastics), climate change, invasive species, diseases, hunting, the wildlife trade, and more.
- The 2022 update to the “State of the World’s Birds” report notes winners and losers amid increasing human alteration of the planet, but documents a continuing downward trend.
Scientists uncover widespread declines of raptors in Kenya
- New research has found a steep decline in numbers for Kenya’s raptors over the past 40 years.
- Encounters with 19 of 22 species studied using road surveys fell during that period, 14 of these declining by 20-95% when compared to the 1970s.
- The study’s findings underlined the importance of protected areas for Kenya’s raptors as populations declined less severely inside parks and reserves.
Boom and bust on Lake Victoria: Q&A with author Mark Weston
- In a new book, British author Mark Weston examines an environmental crisis on East Africa’s Lake Victoria that’s been a century in the making and stems from the introduction of the non-native Nile perch to the lake in the 1950s.
- Weston lived on Ukerewe, the lake’s largest island, for two years, and relates the knock-on legacy of the fish’s introduction through the experiences of the people he met there.
- The boom and bust of the fishery brought about a surging population, deforestation, declining land fertility, and increased pollution in the lake.
- With Nile perch catches down precipitously and little else to sustain the economy of Ukerewe, residents struggle through poverty, lack of opportunity and a trickling exodus from the once-prosperous community, in search of a better life for themselves and their families.
Amid war, Ukrainians are tracking Russia’s crimes against the environment
- With civilian and political welfare as the Ukrainian government’s number one priority, environmental destruction has largely been overlooked during the Russian invasion of Ukraine.
- But civilians and experts alike have rallied together to record more than 100 separate instances of “crimes against the environment,” with the aim of bringing Russia to justice under international courts after the war.
- From the destruction of fuel and gas depots to the long-term effects of ecosystem services on Ukraine, known as the “breadbasket of the world,” environmental impacts can also become humanitarian crises, activists warn.
Saving the near-extinct estuarine pipefish means protecting estuary health
- The critically endangered estuarine pipefish is known to inhabit only two estuaries on the eastern coast of South Africa.
- Recent studies are uncovering how the health of its estuarine habitat rests on a dynamic balance between freshwater inflows that support the food change, and salinity levels that promote growth of eelgrass habitat for pipefish and other species.
- Genetic analysis of the remaining estuarine pipefish populations has found low genetic diversity, highlighting a further risk to its conservation.
- Conservationists are working toward a plan to protect the species and the wider ecology of the estuaries it inhabits.
As animal seed dispersers go the way of the dodo, forest plants are at risk
- Many plants rely on animals to reproduce, regenerate and spread. But the current sixth mass extinction is wiping out seed-dispersing wildlife that fill this role, altering entire ecosystems.
- Thousands of species help keep flora alive, from birds and bats to elephants, apes and rodents.
- Animals give plants the ability to “move,” with the need for mobility rising alongside warming temperatures and more frequent extreme weather events. Transported elsewhere, plants may be able to “outrun” a warming climate.
- There are growing efforts to restore these critical ecological relationships and processes: protecting and recovering wild lands, identifying and rewilding key animal seed dispersers, reforesting destroyed habitat, and better regulating destructive logging and agricultural practices.
Unseen crisis: Threatened gut microbiome also offers hope for world
- Plants and animals provide a home within themselves to an invisible community of microbes known as the microbiome. But these natural microbial communities are being degraded and altered by human-caused biodiversity loss, pollution, land-use change and climate change.
- On the macro level, habitat loss and diminished environmental microbe diversity, particularly in urban environments, is altering the gut microbiomes of humans and wild animals. Studies have linked microbiome changes to higher risk of chronic and autoimmune diseases.
- Coral bleaching is an extreme example of climate stress-induced microbiome dysfunction: During heat waves, beneficial microbes go rogue and must be expelled, leaving the coral vulnerable to starvation. Microbiome resilience is key to determining corals’ ability to acclimate to changing ocean conditions.
- There are solutions to these problems: Inoculating coral with beneficial microbes can reduce bleaching, while the restoring natural green spaces, especially in socioeconomically deprived urban areas, could encourage “microbiome rewilding” and improve human and natural community health.
In Mexico, a race to save the last wetlands of San Cristóbal de las Casas
- The mountain wetlands of La Kisst and María Eugenia are protected areas in the state of Chiapas, and have been listed as Ramsar sites of international importance. But that hasn’t been enough to guarantee their conservation.
- For more than a decade, local organizations have spoken out against the degradation of the wetlands, which provide around 70% of the water used in the city of San Cristóbal de las Casas.
- The National Commission on Human Rights (CNDH) said not all officials have worked to guarantee wetland conservation.
- It has called for the creation of a program to recover ecosystems and investigate those responsible for environmental crimes.
Global biodiversity is in crisis, but how bad is it? It’s complicated
- Biodiversity has been defined as one of nine planetary boundaries that help regulate the planet’s operating system. But humanity is crossing those boundaries, threatening life on Earth. The big question: Where precisely is the threshold of environmental change that biodiversity can withstand before it is destabilized and collapses planetwide?
- The planetary boundary for biodiversity loss was initially measured by extinction rates, but this, as well as other measurements, have proved to be insufficient in determining a global threshold for biodiversity loss. At present, a worldwide threshold for biodiversity loss — or biosphere integrity, as it is known now — remains undetermined.
- However, thresholds for biodiversity loss can be clearly defined at local or regional levels when an ecosystem goes through a regime shift, abruptly changing from one stable state to another, resulting in drastic changes to biodiversity in the changed ecosystem.
- While the planetary boundary framework provides one way of understanding biodiversity or biosphere integrity loss, there are many other measures of biodiversity loss — and all point toward the fact that we are continuing to dangerously destabilize life on Earth.
‘Nature has priority’: Rewilding map showcases nature-led restoration
- The Global Rewilding Alliance and OpenForests have officially launched a map of rewilding projects around the world.
- Organizations have contributed stories, photos and videos for projects in 70 countries covering 1 million square kilometers (386,000 square miles), and the alliance’s leaders say more will be added.
- Rewilding is a type of ecological restoration that aims to restore natural dynamics and processes to ecosystems.
- Proponents of the approach say it has the potential to address both biodiversity loss and climate change.
Indigenous communities transform a Mexican desert landscape into forest
- In the Mexican state of Oaxaca, 22 communities have taken on the challenge of reviving soils depleted by centuries of overgrazing.
- Over the last two decades, they’ve managed to restore at least 20,000 hectares (49,000 acres), turning many sites into burgeoning forests.
- The task is especially challenging because the communities are starting from “less than zero” — having to find ways to restore their soil before they can even think about planting trees.
- The success of the initiative means the communities can now look forward to more options for forest-based livelihood, such as agroforestry or even selling carbon credits.
Greek conservationists collaborate to protect endemic species in face of climate change
- Across Greece, conservation NGOs are working in close collaboration to study and save numerous endemic species found nowhere else.
- Often working in areas famed for Greek mythology like Mount Olympus and Mount Oiti, the plants and animals now need what seems like divine intervention to survive the ravages brought by climate change.
- Why so many endemic species? Greece has “an amazing diversity of climates and also soils. This creates an amazing diversity of life,” one conservationist tells Mongabay.
Winds of change: Detecting species from airborne DNA just got real
- In recent years, environmental DNA has enabled conservationists and citizen scientists to study entire ecosystems and to monitor elusive species that would otherwise evade detection.
- A suite of new research studies demonstrates that eDNA extracted from thin air can be used to identify a variety of plants and animals.
- Airborne DNA technology is potentially a valuable new tool for monitoring biodiversity, with particularly promising applications for monitoring rare and endangered species and providing early warning of invasive organisms.
- While a lot of work to hone the technique remains, experts are hopeful that prior advances in other eDNA technologies will help to accelerate the development of airborne DNA sampling so that it can be used in the field.
Even degraded forests are more ecologically valuable than none, study shows
- From providing clean air and water to temperature regulation, degraded tropical forests provide ecosystem services valued by Indigenous communities in Malaysia, according to new research.
- Researchers found the ecosystem services most highly prioritized by communities also tended to be ecologically valuable ones, highlighting common interests between Indigenous groups and conservation that can be tapped through community-based projects.
- The study comes amid a government-led push to convert hundreds of thousands of hectares of degraded forests in Sabah into timber plantations.
- Forests, even logged ones, provide unique services tied to Indigenous culture, such as hunting activities, that cannot be replaced by timber plantations, researchers said.
Despite sanctions, U.S. companies still importing Myanmar teak, report says
- U.S. timber companies undercut sanctions to import nearly 1,600 metric tons of teak from Myanmar last year, according to a new report.
- Advocacy group Justice for Myanmar said in its report that firms have been buying timber from private companies acting as brokers in Myanmar, instead of directly from the state-owned Myanma Timber Enterprise, which is subject to U.S. sanctions.
- With MTE under military control, Myanmar’s timber auctions have become more opaque, making it difficult to take action against companies circumventing sanctions.
How can illegal timber trade in the Greater Mekong be stopped?
- Over the past decade, the European Union has been entering into voluntary partnership agreements (VPAs) with tropical timber-producing countries to fight forest crime.
- These bilateral trade agreements legally bind both sides to trade only in verified legal timber products.
- There is evidence VPAs help countries decrease illegal logging rates, especially illegal industrial timber destined for export markets.
- Within the Greater Mekong region, only Vietnam has signed a VPA.
How does political instability in the Mekong affect deforestation?
- Myanmar’s return to military dictatorship earlier this year has sparked worries among Indigenous communities of possible land grabs.
- It has also ignited concerns about a return to large-scale natural resource extraction, which has historically been an important source of funding for the junta.
- In the months since the coup, many of the country’s environmental and land rights activists have either been arrested or gone into hiding.
- The military has bombed forests and burned down Indigenous villages in Karen state, forcing minorities to flee to neighboring Thailand.
Decline of threatened bird highlights planning importance of bison releases
- In a recent study, a team of biologists found that the release of American bison (Bison bison) on a small section of North American grassland led to declines in a species of bird called the bobolink (Dolichonyx oryzivorus), likely because the density of the bison in the fenced-in study area was too high.
- Bison once numbered in the tens of millions on the Great Plains, but hunting drove the population down to around a thousand by the end of the 1800s.
- Concerted efforts to protect remaining wild populations and reintroduce the animal to parts of the Plains has resulted in a resurgence, and the species is no longer in danger of imminent extinction.
- However, the results of the bobolink study reveals that bison releases and reintroductions must be done carefully to avoid negative impacts on the broader ecosystem.
Scientists on a quest to map worldwide web of fungi beneath our feet
- Interconnected bodies of fungi form vast underground networks through the Earth’s soils, transporting nutrients and water across ecosystems and sequestering vast amounts of carbon out of the atmosphere.
- Experts agree that protecting fungi and focusing conservation efforts belowground could help to mitigate global challenges like climate change, biodiversity loss, land use change and pollution.
- A new initiative is embarking on the first global effort to document and map the world’s network-forming fungi, using eDNA and machine learning to identify and protect global hotspots of fungal biodiversity.
- Fungi are increasingly viewed as a nature-based solution to manage global carbon budgets, restore degraded ecosystems, remediate contaminated soils and speed the transition toward sustainable agriculture.
As Ethiopia’s war rages, a 400-year-old conservation site is scarred by battle
- A major fire has burned more than 1,000 hectares (nearly 2,500 acres) of grassland in the Guassa Community Conservation Area in Ethiopia’s central highlands.
- The area is among the oldest examples of community-managed conservation in Africa, centered on preserving the Festuca grass that is used for thatching roofs.
- The grasslands are also home to endangered Ethiopian wolves and gelada baboons, and more recently have become a favored ecotourism site.
- It’s still unclear what triggered the blaze, but the area was the site of a battle in Ethiopia’s ongoing civil war in late November.
Conservation and food production must work in tandem, new study says
- Confining conservation efforts to only 30% of Earth’s land may render a fifth of mammals and a third of birds at high risk of extinction, according to a new study.
- If that 30% were to be strictly protected without accounting for food production activities, it could also result in substantial local or regional food production shortfalls, the researchers said.
- Instead, they propose an integrated land-use planning strategy where conservation and food production goals are considered in tandem, including through mixed approaches like agroforestry.
- Such a model would not only generate less food production shortfalls, but also leave just 2.7% of mammal and 1.2% of bird species at risk of extinction.
Hold the tree planting: Protect ecosystems first for maximum carbon storage, study says
- When it comes to slowing climate change, there’s one natural solution that has recently gripped the world: large-scale tree planting and reforestation.
- But a new study warns that other natural climate solutions should be considered first.
- By comparing different natural climate solutions against four criteria, the study proposes a hierarchy: protect ecosystems first, then improve their management, and lastly restore them.
- Protecting natural ecosystems offered the greatest climate benefits, fairly quickly, at relatively low cost, while at the same time providing other benefits for people and wildlife, such as reducing the impact of extreme weather and yielding clean air and water.
‘Our land, our life’: Okinawans hold out against new U.S. base in coastal zone
- Opponents of the planned relocation of a U.S. military base in Okinawa say they remain undeterred despite the defeat in elections last month of the opposition party that supported the cause.
- Local activists plan to continue opposing the relocation of the Futenma Marine base, from the densely populated city of Ginowan to the less crowded Henoko Bay coastal area.
- The proposed new facility and other military bases in Okinawa have been linked to toxic environmental pollution, military-linked sexual violence, and historical land conflicts between native Okinawans and the mainland Japan and U.S. governments.
- The Okinawa prefecture government recently rejected central government plans to sink more than 70,000 compacting pillars into Henoko’s seabed for construction, which would impact coral and seagrass that host more than 5,000 species of marine life.
In China, agroforestry serves up tea with a spoonful of sustainability
- In Yunnan, China, smallholder farmers applying agroecological principles to tea cultivation have seen results in the form of better-tasting tea, lower management costs, and richer biodiversity.
- With ethical consumerism on the rise, integrating agroecology could be an opportunity for tea farms to contribute toward conservation goals, experts say.
- Tea farmers and scientists have observed a shift toward more sustainable farming practices, but highlight a need for government policy that can further boost these bottom-up changes.
- By sequestering carbon and contributing to local food security, agroforests can help humans adapt to and combat the climate crisis.
Study shows ‘encouraging’ results of China’s bid to protect coastal wetlands
- China’s coastal wetlands experienced a significant recovery in recent years after many decades of loss and destruction, a new study suggests.
- Satellite imagery shows that different kinds of coastal wetlands deteriorated between 1984 and 2011, but began to improve from about 2012.
- The degradation of China’s coastal wetlands is largely attributed to land reclamation, construction and other economic activities, the study suggests.
- But the nation has recently recognized the importance of coastal wetlands, and initiated several projects aiming to restore and conserve these ecosystems.
Study chronicles dying of a lake in PNG with advent of oil & gas activities
- A new study finds warning signs of ecosystem collapse at Lake Kutubu in Papua New Guinea, a wetland of international significance.
- The warning signs come in the form of major shifts in algal composition and dung-inhabiting fungi in the lake sediment in the 1980s and 1990s, indicating a drop in water quality and coinciding with oil and gas extraction in the area.
- The lake used to have extensive beds of microalgae known as charophytes, which provided a breeding ground for endemic fish and crayfish, but these beds have since all but disappeared.
- The researchers have called for action such as monitoring of the lake’s algae and fish populations to save the lake from ecological collapse.
Green groups call for scrapping of $300m loan offer for Borneo road project
- The Asian Development Bank is considering a $300 million loan proposal from the Indonesian government to fund a road project in Borneo.
- The 280-kilometer (170-mile) project across North and East Kalimantan provinces are designed to boost economic growth and further the integration of the Malaysian and Indonesian palm oil industries.
- Environmental groups around the world have urged the ADB to impose stricter environmental and social requirements for the project to reduce its expected impacts on the environment and the Indigenous communities living in the region.
- Indigenous peoples like the Dayak rely on the forests staying intact, as do critically endangered species such as Bornean orangutans.
Inland mangroves reveal a tumultuous climatic past — and hint at our future
- A new study concludes that the presence of inland mangroves along a river in southern Mexico was the result of climate change-driven sea level rise during the Pleistocene Epoch, some 115,000 to 130,000 years ago.
- The researchers’ analysis of the genetic history of the mangrove trees suggests that they are closely related to trees found on the coastline, and sediments nearby are similar to those found in ocean environments.
- Publishing their work Oct. 12 in Proceedings of the National Academy of Sciences, the team notes that their research highlights the impacts of global climate change.
Fate of Malaysian forests stripped of protection points to conservation stakes
- In the seven years since Jemaluang and Tenggaroh were struck from Malaysia’s list of permanent forest reserves, the two forests in Johor state have experienced large-scale deforestation.
- The clearance is reportedly happening on land privately owned by the sultan of Johor, the head of the state, calling into question the effectiveness of the Central Forest Spine (CFS) Master Plan, a nationwide conservation initiative the two reserves had originally been part of.
- The CFS Master Plan is currently being revised, with experts seeing the review as a chance to change what has been a largely toothless program, beset by conflicts of interest between federal and state authorities.
- As the revision nears completion, Jemaluang and Tenggaroh highlight how much has been lost, but also what’s at stake for Malaysia’s forests, wildlife and residents.
Fires leave trail of dead wildlife, scorched land in Bolivia’s protected areas
- Forest fires in Bolivia have torn through several protected areas, including San Matías and Ñembi Guasu, with experts warning of a repeat of the widespread burning of recent years.
- The main cause of the fire is slash-and-burn clearing by farmers ahead of crop planting, which local laws permit, even in forested areas.
- The burning has spread beyond Bolivia’s borders and into Paraguay, where the fires raged for several days in the Pantanal wetlands before being doused by rains.
Look beyond carbon credits to put a price on nature’s services, experts say
- Valuing nature as a “new asset class” could be the key to getting trillions of dollars in investments to flow to nature-based solutions, experts said at a recent sustainability conference in Singapore.
- Because policymakers and investors haven’t been able to properly value nature, the finance industry has been using carbon markets as a proxy for investing in it.
- Governments should account for the ecosystem benefits of nature beyond carbon capture, the experts said.
- Proper valuation of nature’s benefits requires inputs from not only investors, but also scientists, communities and NGOs.
When a tree falls in the forest, you can still hear the birdsong
- Recovering forests in Malaysia that were once selectively logged are an important habitat for tropical forest birds, a new study has found.
- The study surveyed bird biodiversity in Kenaboi State Park, which was last logged in the 1980s and declared as a protected area in 2008.
- Unlike the state park, other selectively logged forests across Malaysia are commonly turned into oil palm plantations and agricultural land rather than being allowed to recover, the researchers said.
- They recommend foresters make use of post-harvest management techniques to speed up recovery for selectively logged forests, and for state governments to declare these forests as protected areas.
Marine experts flag new Peru marine reserve that allows industrial fishing
- Experts say the establishment of a new marine protected area off Peru that allows large-scale fishing and the capture of deep-sea cod will damage the biodiversity inside the reserve.
- Nazca Ridge National Reserve is the first fully marine protected area in Peru, covering 62,392 square kilometers (24,089 square miles) of the ocean.
- Its establishment in June increased the proportion of the country’s territorial waters under some sort of protection from less than 1% to nearly 8%.
Environmental activist ‘well-hated’ by Myanmar junta is latest to be arrested
- As demonstrations and deadly crackdowns continue in Myanmar, land and environmental defenders are increasingly under threat.
- On Sept. 6, environmental and democracy activist Kyaw Minn Htut became one of the latest political prisoners; authorities had detained his wife and 2-year-old son a day earlier.
- He had openly challenged the military and reported on illegal environmental activities, making him a “well-known and well-hated” target, fellow activists said.
- Some 20 environmental organizations across the world have signed a statement calling for Kyaw Minn Htut’s release.
Borneo’s bearded pigs and traditional hunters adapted to oil palms. Then came swine fever
- Oil palm expansion and urbanization have altered the traditional hunting of bearded pigs by the Indigenous Kadazandusun-Murut (KDM) community in Sabah, Malaysia, a new study has found.
- Researchers interviewed 38 hunters on changes in pig behavior and hunting practices before the African swine fever (ASF) epidemic hit Sabah in 2021.
- They found that even though pig hunting patterns have changed dramatically, the activity remains a cornerstone of KDM communal culture for food, sport, gift-giving, festivals and celebrations.
- As ASF devastates wild pig populations, the researchers’ findings highlight a need for long-term hunting management that conserves both the bearded pig and Indigenous cultural traditions.
Highway cutting through Heart of Borneo poised to be ‘very, very bad’
- With Indonesia planning to shift its capital from Jakarta to the Bornean province of East Kalimantan, infrastructure development pressures on the island have intensified.
- Neighboring Malaysia is adding new stretches to the Pan Borneo Highway to capitalize on spillover economic benefits; within Indonesia, East Kalimantan’s developmental gains are also expected to trickle to other provinces through the transboundary highway.
- While the new roads could spur economic development in remote villages, they also carve into protected areas in the Heart of Borneo, opening them up for resource extraction.
- In particular, the roads could fast-track development of a new “oil palm belt,” with disastrous consequences for the wildlife and Indigenous peoples of Borneo, and for global climate, experts say.
In Chile, a prickly coalition tries to bring a salt flat back to life
- Indigenous communities, environmental activists and a mining company have agreed on a set of measures to try to save the Salar de Punta Negra salt flat in northern Chile.
- Communities say the extraction of groundwater by copper miner Minera Escondida has drained the salt lake and caused irreparable environmental harm.
- Under a court-mediated settlement, all sides have agreed to a series of scientific studies to help identify the cause of the problem and options for addressing it.
- Not everyone is happy about the agreement, however, with some criticizing the meager budget allocation for carrying out the studies compared to the much larger funding for publishing the results.
Platform presents unpublished data on Brazilian biodiversity
- Partnership between scientists and journalists translates scientific data into visual information to warn of the importance of preserving Brazil’s biomes.
- Brazil alone accounts for 17% of the entire terrestrial territory of the tropics with a biodiversity that is more abundant than entire continents: over 20% of the freshwater fish on the planet and 17% of all birds are found in Brazil.
- One problem is the lack of investment in research to survey biodiversity, which usually comes at a slower pace than changes in ecosystems – animals and plants are at risk of disappearing before scientists are able to get to know them.
Seed dispersal is just as important as pollination (commentary)
- Why does it seem like conservationists only care about pollination, and the creatures like bees that do it?
- Seed dispersal is every bit as important, and to ensure a future with the greatest plant diversity, we should focus effort on conserving the animal groups known for this activity, known as ‘zoochory.’
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
For monitoring mammals, eDNA boasts ‘killer feature’ over other methods
- Mounting evidence suggests that the fast-developing tool of eDNA could be a game-changer for terrestrial mammal monitoring.
- A new study demonstrates that eDNA analysis of stream water can reveal the diversity of terrestrial mammals in a large landscape as effectively as camera trapping and for a fraction of the cost.
- Traditional mammal survey methods can be time-consuming, expensive and far from failsafe; eDNA is a reliable and comparatively inexpensive way for conservationists to gain a snapshot of an ecosystem’s mammal fauna, scientists say.
- It could also have a big impact on conservation, since eDNA data allows timely decisions on which species to prioritize and which areas to protect.
Scientists turn to eDNA to curtail the freshwater extinction crisis
- Freshwater ecosystems are understudied and underfunded, resulting in a lack of information on what species are at risk of extinction.
- The eBioAtlas program, a partnership between the IUCN and NatureMetrics, uses environmental DNA gathered from freshwater samples to figure out what freshwater ecosystems to conserve and what species to prioritize.
- So far, a pilot study in southeast Liberia has successfully picked up environmental DNA from nearly 170 species, including some that are critically endangered.
- The new data will provide up-to-date information for the IUCN Red List of Threatened Species and empower local communities to maintain ownership of their land and water resources.
Nine principles for the UN Decade on Ecosystem Restoration (commentary)
- Oil drilling on Russia’s Arctic coast has led to loss of vegetation and the organic soil layer, with sediments now running into rivers: permafrost thawing is also increasing due to carbon emissions.
- Without clear parameters for what constitutes successful restoration, restoration projects in places like this may achieve one narrow objective, such as carbon capture, but may not also benefit biodiversity, or the health, wellbeing, and livelihoods of people and local communities.
- In April, a group of restoration experts met to define ‘net gain’ from restorative activities, establish a framework to help prioritize nature-based restorative activities and draft common principles for all types of ecosystem restoration, in support of the UN Decade of Ecosystem Restoration.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Nauru’s intention to mine the seabed prompts alarm among conservationists
- Nauru has notified the International Seabed Authority (ISA) that its sponsored entity, Nauru Ocean Resources Inc. (NORI), plans to commence deep-sea mining in two years’ time, triggering a two-year rule embedded in the U.N. Convention on the Law of the Sea.
- The ISA has yet to generate a mining code that would set out rules and regulations for deep-sea mining activities.
- Experts are concerned that the ISA will prematurely approve Nauru’s application and that deep-sea mining will commence before we fully understand the damage it could cause to biodiversity and ecosystems.
Earth tipping points could destabilize each other in domino effect: Study
- A new risk analysis has found that the tipping points of five of Earth’s subsystems — the West Antarctic Ice Sheet, the Greenland Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), the El Niño–Southern Oscillation (ENSO) and the Amazon rainforest — could interact with each other in a destabilizing manner.
- It suggests that these changes could occur even before temperatures reach 2°C (3.6°F) above pre-industrial levels, which is the upper limit of the Paris Agreement.
- The interactions between the different tipping elements could also lower critical temperature thresholds, essentially allowing tipping cascades to occur earlier than expected, according to the research.
- Experts not involved in the study say the findings are a significant contribution to the field, but do not adequately address the timescales over which these changes could occur.
Big bioacoustics boost: Cornell University program receives $24 million donation
- The field of bioacoustics has been a game changer when it comes to monitoring and discovering new things about animals and ecosystems, both on land and at sea.
- Still a relatively new discipline, one of the leading programs in the field globally was founded in the 1980s at Cornell University, which has just announced a donation of $24 million to support its bioacoustics work.
- The K. Lisa Yang Center for Conservation Bioacoustics will use the funds to accelerate its training of researchers, facilitate development of new tools and partnerships, and build a global network of people who can share bioacoustics best practices.
Study shows it took the Amazon as we know it over 6 million years to form
- An asteroid impact near Mexico 66 million years ago triggered an ecological catastrophe that claimed nearly half of all plant species and took Amazon forests more than 6 million years to recover from.
- Colombian researchers analyzed fossilized pollen and leaves and found plant diversity declined by 45% after the impact; when plant diversity finally recovered, open forests of ferns and conifers had been replaced by dense, closed-canopy forests dominated by flowering plants.
- The researchers suggested three interlinked explanations for the sudden transition: the extinction of large-bodied dinosaurs at the end of the Cretaceous reduced forest disturbance; dust from the impact acted as a fertilizer; conifers were more likely to go extinct.
- In the time periods studied, Earth’s climate was warmer and CO2 levels were higher, showing that climate alone is not enough to trigger a forest-to-savanna transition, with the pace of warming and deforestation the crucial puzzle pieces that determine whether today’s forests can survive.
Reptile traffickers trawl scientific literature, target newly described species
- The descriptions and locations of new reptile species featured in scientific literature are frequently being used by traders to quickly hunt down, capture and sell these animals, allowing them to be monetized for handsome profits and threatening biodiversity.
- New reptile species are highly valued by collectors due to their novelty, and often appear on trade websites and at trade fairs within months after their first description in scientific journals.
- In the past 20 years, the Internet, combined with the ease and affordability of global travel, have made the problem of reptile trafficking rampant. Some taxonomists now call for restricted access to location information for the most in demand taxa such as geckos, turtles and pythons.
- Once a new species has been given CITES protection (typically a lengthy process), traders often keep the reptiles in “legal” commercial circulation by making false claims of “captive breeding” in order to launder wild-caught animals.
Belize’s Maya Forest Corridor a ‘missing link’ to giant rainforest reserve (commentary)
- With nearly 40% of its lands under protection, Belize already contributes significantly to the IUCN’s post-2020 biodiversity framework of preserving 30% of the planet by 2030.
- Now conservationists hope to create the Maya Forest Corridor, connecting the massive Belize Maya Forest in the country’s northwest with the Maya Mountains Massif network of protected areas in southern Belize.
- It would also connect these areas of Belize with adjacent protected areas of La Selva Maya in Guatemala and Mexico, and become the largest rainforest preserve north of the Amazon, a haven for threatened and endangered species including the jaguar, the Central American river turtle and spider monkey, and Baird’s tapir.
- “My hope is the corridor will be approved and a massive expanse of Central American rainforest will be fused together,” writes a research professor with Northern Arizona University in this commentary piece. The views expressed are of the author, not necessarily Mongabay.
