In Nepal, centuries-old Buddhist incense tradition faces overharvesting, climate threats
- Lighting sang, a traditional incense made from juniper and other local plants, is a sacred daily ritual among Buddhist communities in Nepal’s Trans-Himalayan regions like Manang, symbolizing purification and peace.
- Though classified as “least concern” globally by the IUCN, black juniper faces pressure due to habitat fragmentation, overharvesting for incense and increasing commercial demand.
- Climate change, especially prolonged winter droughts and delayed snowfall, is impairing the regeneration of juniper shrubs, making them more vulnerable despite their natural resilience in harsh alpine conditions.
Invasive whiteflies pose a new threat to Bangladesh’s cash crops
- The invasion of sap-sucking whiteflies in Bangladesh’s agricultural farms, especially in those of coconuts, bananas and guavas, has become a serious concern among farmers as it can cause widespread damage.
- Farmers first noticed these insects in 2019 on coconut plants, and observed they affected the growth of the plants and yields. Research shows whiteflies have already made 61 types of plants as their hosts in Bangladesh.
- Though the researchers have yet to confirm how they entered the country, they suggest it could be via imported high-yielding coconut plants in 2014 and 2015.
- Researchers suggest deploying a parasitoid wasp, Encarsia guadeloupae, which is considered to tackle the invasion of the whitefly.
Ground-level ozone wreaks havoc on warming planet
Ozone as a layer several kilometers up in the atmosphere protects living beings, including humans, from ultraviolet rays. But its accumulation at ground level can be very dangerous, Mongabay contributor Sean Mowbray explains in an article published in April. Ground-level, or tropospheric, ozone forms when methane, nitrogen oxides, carbon monoxide and volatile organic compounds react […]
Seeds rescued from India’s coffee farms could help forest restoration

What the study says: While coconut palm is an integral part of the cultures and economy of Pacific Island communities, colonial powers […]
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.
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.
Digitizing 6 million plant specimens: Interview with Gunter Fischer & Jordan Teisher

- The team behind the project says they hope the reference database will speed up plant identification; it could also potentially be used to gauge the health of forests in the face of climate change.
Survey uncovers ‘wildlife treasure’ in Cambodian park — but also signs of threats
- A survey of a little-known patch of forest on Cambodia’s border with Thailand has uncovered a “treasure of wildlife,” including potentially new-to-science plant species.
- The Samlout Multiple Use Area was established 30 years ago to conserve natural resources while also developing economic activities, but deforestation rates in the region have matched the national average.
- The survey, conducted by Fauna & Flora and commissioned by the Maddox Jolie-Pitt Foundation, found about 140 bird, 30 mammal, 15 bat and 50 orchid species.
- But camera traps used in the survey also recorded the presence of armed humans in the area and evidence of snare traps, prompting calls for improved protection by law enforcement agencies.

Rare new Guinean flower is ‘canary in a coal mine’ — but in an actual iron mine
- Scientists have described a new species of flower that appears to only grow in a small forest patch on the slopes of a mountain range in Guinea, West Africa, where extensive open-cast mining for iron ore is set to begin soon.
- There are thought to be as few as 100 of the Gymnosiphon fonensis flowers in existence in the Boyboyba Forest, which is part of the Pic de Fon classified forest reserve in the southeast of the country.
- Mining firm Rio Tinto has pledged to protect the Boyboyba Forest and the plants and animals that live in it.
- But Boyboyba makes up only a tiny fraction within a mosaic of forests and grasslands whose ecological integrity depends on linkages extending across Simandou’s 100-kilometer (60-mile) length.

Poachers target South Africa’s ‘miracle’ plant with near impunity
- South Africa has faced a surge in poaching of rare succulents by criminal syndicates since 2019.
- A recent spike in prices paid for a different kind of plant, a drylands-adapted lily, the miracle clivia (Clivia mirabilis), has drawn the attention of plant-trafficking syndicates to the lone reserve where it grows.
- Large numbers of clivias have been seized by law enforcement, raising fears that this rare plant is quickly being wiped out from the limited range where it’s known to occur.
- Reserve staff and law enforcement agencies are underfunded and spread too thinly across the vast landscapes of South Africa’s Northern Cape province targeted by plant poachers.
Greater Mekong serves up 234 new species in a year, from fanged hedgehog to diva viper
- Researchers and local nature enthusiasts described 234 new-to-science species across the Greater Mekong region in 2023.
- Among the new assortment of critters are sweet-smelling plants, glamorous snakes, a dragon lizard, a psychedelic-orange crocodile newt, and several new mammals, including a mole shrew and a fanged hedgehog.
- The Greater Mekong is a fast-developing region of Southeast Asia, characterized by intensive agriculture, internationally significant inland fisheries and rapid urban expansion.
- As such, the newly described species and their habitats are under pressure from multiple threats, not least from the illegal wildlife trade that also flourishes in the region. Experts say consistent and concerted action is required to secure their future.

Researcher discovers new role played by manatees, ‘the gardeners of the Amazon’
- According to a new study, the Amazonian manatee is a seed disperser; a researcher found germinating grasses in its feces.
- The discovery was made in Lake Amanã, in the Amazon, where 96 samples of manatee feces were collected; surprisingly, they contained 556 intact seeds.
- Manatees eat 40 kilograms (88 pounds) of aquatic plants a day and migrate long distances. This finding shows that the manatee is a crucial vector for dispersing seeds between fertile areas such as floodplains and nutrient-poor areas such as the swamp forests known as igapós; this activity enhances biodiversity in Amazonian environments, especially in times of climate change and environmental degradation.
- Despite its vital ecological function, the manatee is listed as vulnerable to extinction; Illegal hunting, facilitated by periods of extreme drought, is one of the main threats, along with climate change, which affects both their diet and their migratory routes.
In a Noah’s Ark move, PNG migrants bring thousands of trees to safer ground
- Facing sea level rise and food insecurity, 17 families from the Carteret Islands have relocated to nearby Bougainville, bringing hundreds of specimens of trees and plants, representing dozens of species, across a small stretch of ocean.
- They’ve planted more than 175,000 plants, breathing life into a forest on new lands donated by the Catholic Church.
- This “green migration” is helping them preserve their lifestyle and identity, sources say, echoing the journey of early Polynesian settlers who carried “canoe plants” as they sailed and settled across the Pacific.
- Scientists say green migrations could become part of climate relocation planning, but there also needs to be careful consideration of whether species can be moved and become unsustainably invasive.
Last wild hurricane palm of its kind falls, marking extinction

Botanical gardens play key role in biodiversity & climate conventions (commentary)
- “As world leaders and scientific institutions from across the globe gather to discuss the biodiversity crisis at COP16 and climate change at COP29 this fall, it’s critical that they do not neglect the important work that is already being done by one of the world’s key stewards of nature – botanical gardens,” a new op-ed argues.
- Botanical gardens have an important role to play in the overall effort to combat the dual climate and biodiversity crises and can offer important solutions, but they are often underutilized, despite housing a wide array of experts on plants and fungi.
- “At the rate the planet is warming, there is no time to leave their untapped potential behind,” writes the CEO of The New York Botanical Garden.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
The Panamanian shamans working to save their ancestral medicinal plants
- In Santa Marta, a small village in Panama’s Ngäbe-Buglé Indigenous region, aging shamans are seeking to preserve and pass down knowledge of traditional medicinal plants.
- Village members say knowledge of how to identify and use local sacred medicinal plants has assisted the community to treat illnesses and viruses, such as COVID-19.
- Fearing this ancestral knowledge will be lost, Santa Marta’s shamans made a book with photos, names and information about the curative properties of local plants.
- In 2022, researchers from the Technological University of Panama published an ethnobotanical study on the species of Santa Marta’s traditional medicine plants in an effort to safeguard this sacred knowledge.
Fishers & scientists unite to restore seaweed populations on Chilean coast
- Scientists and fishers in Chile are repopulating a coastal area exposed to high levels of pollution with two species of seaweed that were once abundant in the area.

Experts call for urgent action as invasive species threatens Brazil mangroves
- The Sonneratia apetala plant is native to India, Bangladesh, Sri Lanka and Myanmar, yet biologists have found hundreds of specimens permeating the mangroves in the south of Brazil.
- Researchers believe the seeds were transported on ships from China and released at the port just 2 kilometers (1.6 miles) from the mangroves, where they were carried in the currents and rapidly spread.
- Experts warn that S. apetala could have severe ecological impacts, including the loss of biodiversity as it outcompetes native plants; they also fear it might spread to other mangroves.
- Since May 2023, researchers have been advocating for the total eradication of S. apetala in Brazil. However, Brazilian authorities only announced last month that they would remove the species, and the details of how this will be done have not yet been specified.
To save endangered trees, researchers in South America recruit an army of fungi
- Mycorrhizal fungi live in symbiosis with plants, providing them with nutrients necessary to thrive and potentially playing a key part in preserving threatened species.
- Although research into mycorrhizae has so far been sparse in Latin America, efforts are gaining momentum, with experts studying how the fungi could help save the Colombian black oak, an endangered, endemic species.
- In Huila, Colombia, local communities are successfully working with researchers on a black oak restoration project using seeds “inoculated” with fungi.
In Nepal, a humble edible fern is at heart of human-tiger conflict
- In Kathmandu, fiddlehead ferns, also referred to as niuro locally, are highly prized, especially in the monsoon season when the markets first stock them.
- Niuro is also a vital source of income for people in Nepal’s lowlands, especially those close to national parks like Chitwan and Bardiya, where the fern grows abundantly.
- News reports of fatalities related to niuro collection frequently highlight the risks involved, as harvesters frequently put their lives in danger to collect more ferns for financial gain.
- In order to lessen conflicts between people and wildlife, one piece of advice is to update community forest management plans to incorporate safer methods for gathering wild edibles like niuro and to look into sustainable livelihood options.
Patents can serve as early-warning system for wildlife trade trends

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.
In Brazil’s Pantanal, women find empowerment working with nature’s bounty
- In western Brazil’s Pantanal wetland, two socioenvironmental projects based on products from local biodiversity are encouraging women to take the lead in creating their own livelihoods.
- In Barão de Melgaço municipality, women collect water hyacinths, whose fibers they use to create a range of handicrafts, while in neighboring Poconé municipality, women gather and shell fruit from the cumbaru tree to sell as a popular snack.
- By generating an income for the participants, the projects give the women greater autonomy and financial independence in a region where patriarchal traditions are still strong.
- The work isn’t without its risks, however: for the fruit collectors, it’s the exhausting labor of working in the sun and hauling sacks, while for the hyacinth weavers, it’s jaguars and giant otters jumping into their canoes.

- Local food advocates are urging communities to cultivate and eat wild edible plant species to conserve traditional knowledge of their rich array.
‘Miracle’ in miniature as rare new plant defies deforestation in Ecuador
- Botanists have identified a new plant species, Amalophyllon miraculum, in a small forest fragment in northwestern Ecuador, highlighting the importance of preserving even small patches of threatened ecosystems.
- The tiny plant, only 5 cm (2 in) tall, was found growing on a boulder in an area that has lost 70-97% of its original forest cover due to agricultural expansion and past government policies encouraging deforestation.
- The researchers say this new species represents hope for biodiversity conservation, showing that unique species can persist even in heavily altered landscapes.
- Conservation organizations are working with local landowners to protect remaining forest areas and cultivate rare species, emphasizing the ecological and human benefits of preserving these ecosystems.
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.
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.
It’s tough to be a wild orchid: Interview with conservation biologist Reshu Bashyal
- Conservation biologist Reshu Bashyal highlights gaps in Nepal’s implementation of CITES regulations, leading to ineffective protection measures.
- Nepal’s transition to a federal system has brought challenges and opportunities for orchid conservation, with local communities often unaware of conservation needs.
- Protected areas struggle to prioritize plant conservation alongside charismatic megafauna, while road construction further fragments orchid habitats.
- Bashyal emphasizes the importance of raising awareness about the significance of wild plants and updating inventories to guide conservation efforts.
DRC’s 1 billion trees program makes progress, but hurdles remain
- According to the FAO, the Democratic Republic of Congo (DRC) loses 500,000 hectares (1.2 million acres) of forest cover every year due to shifting cultivation, mining and illegal and informal logging.
- As part of addressing this, a Congolese government program aspired to plant 1 billion trees between 2019 and 2023, aiming to strengthen climate resilience, alleviate poverty and protect biodiversity.
- Program officials say they achieved 90% of their target. A forestry specialist says that future reforestation efforts should include feasibility studies, informing tree species selection to maintain ecological balance.
Tanzania’s ‘mountain of millipedes’ yields six new species
- Scientists have recently described six new species of millipedes found in Tanzania’s Udzungwa Mountains.
- The six were among thousands of specimens collected by researchers studying forest ecology there and in the nearby Magombera Nature Reserve.
- Magombera was damaged by commercial logging in the 1970s-80s, and affected areas have been overrun by woody vines known as lianas.
- But teams working on the ground think that millipede diversity and abundance in liana thickets is equal to that of undisturbed forests, suggesting they may be dynamic places poised for forest regeneration with minimal human intervention.
‘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.
Traditional Aboriginal fire practices can help promote plant diversity: Study
- While research is still mixed on whether diverse fire patterns promote biodiversity, a new study suggests that practices under active Indigenous stewardship can do so.
- The study draws a reference to Aboriginal Martu peoples in the northwest deserts of Australia, who have an ancient history of fire practices and experience used to manage the land and hunt.
- Martu fire patterns and post-fire stages help influence plant richness and diversity in arid landscapes dominated by spinifex, say the authors say.
- Indigenous burning practices are often carried out during cooler times of the year, such as in the winter for the Martu, which resulted results in slow, cool, and low-intensity fires that reduced the potential for fire burning out of control and into becoming wildfires.
Conflict in the canopy as human and climate factors drive liana dominance over trees
- Lianas, woody vines that rely on trees for structural support, are growing more abundant in tropical forests around the world, negatively impacting forest recovery and carbon sequestration.
- A new study shows that forest disturbance and climate change give lianas a competitive edge over trees.
- Understanding how climate change and disturbance influence liana growth can help forest managers develop management practices to aid recovering forests.
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.
Culture and conservation thrive as Great Lakes tribes bring back native wild rice
- Wild rice or manoomin is an ecologically important and culturally revered wetland species native to the Great Lakes region of the United States and Canada, which once covered thousands of acres and was a staple for Indigenous peoples.
- Over the past two centuries, indiscriminate logging, dam building, mining, and industrial pollution have decimated the wild rice beds, and today climate change and irregular weather patterns threaten the species’ future.
- In recent years, native tribes and First Nations, working with federal and state agencies, scientists and funding initiatives, have led wild rice restoration programs that have successfully revived the species in parts of the region and paved the way for education and outreach.
- Experts say more research and investments must be directed towards wild rice, and such initiatives need the support of all stakeholders to bring back the plant.
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.
In Colombia, race is on to save 8 rare tree species found nowhere else
- Researchers from Colombia’s Humboldt Institute are working with residents of the Claro River Basin in Antioquia department to conserve eight tree species in serious danger of going extinct.
- The species are endemic to Colombia: five are found only in the middle section of the Claro River Basin, while the others have been recorded in the neighboring departments of Santander and Caldas.
- Of the eight tree species being studied, Matisia serpicostata presents the most worrisome situation: only one specimen has been found in the area.
- Researchers and residents have established three tree nurseries to grow these species from seeds and cuttings, and eventually plant the seedlings in the wild.
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.
Ghana’s medicinal plants, the ‘first aid’ for communities, are under threat
- Forest communities in southwestern Ghana use 70 species of medicinal trees to treat up to 83 ailments, according to a recent study.
- These plants contain high levels of bioactive compounds with pharmacological benefits, but many are also threatened by factors including overharvesting and agricultural expansion in the area that drives large-scale deforestation.
- Due to a lack of access to Western medicine and cultural perceptions, traditional medicine is the primary source of treatment for many forest-fringe communities.
- The authors say government-led conservation programs and preserving traditional knowledge is important to conserving these medicinal tree species.
Caribbean traditional plant knowledge needs recognition or it’s lost: Study
- Knowledge of Caribbean ethnobotany has so far been limited and little comprehensive island- or region-wide inventories of Caribbean traditional plant knowledge have been developed.
- A recent study highlights an eight-step action plan to foster greater academic recognition of the botanical tradition of Afro-descendent farmers in research, education and policymaking.
- Considering these farmers’ important roles in promoting plant diversity, the study authors say financial support from local and national governments can strengthen their work as plant stewards.
Bangladeshi farmers eye moringa as a climate and economic solution
- Farmers in Bangladesh are increasingly turning to the fast-growing, drought-resistant moringa (Moringa oleifera) tree, which is indigenous to South Asian nations such as India, Pakistan, Bangladesh and Afghanistan.
- Researchers say moringa is beneficial for human health, as both the leaves and the fruits are rich in nutrients and minerals.
- Researchers also suggest that moringa cultivation could be a part of smart agriculture as climatic patterns change, as the plant can tolerate extreme heat and cold.
- A Bangladeshi entrepreneur has been working to create a social movement and entrepreneurship in moringa cultivation and marketing since 2017; so far, he has engaged some 5,000 farmers in 20 districts of Bangladesh.
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 […]
Photos: Top species discoveries from 2023
- Scientists described a slew of new species this past year, including an electric blue tarantula, two pygmy squid, a silent frog, and some thumb-sized chameleons.
- Experts estimate less than 20% of Earth’s species have been documented by Western science.
- Although a species may be new to science, it may already be well known to local and Indigenous people and have a common name.
- Many new species of plants, fungi, and animals are assessed as Vulnerable or Critically Endangered with extinction as soon as they are found, and many species may go extinct before they are named, experts say.
Some hemp with your wine? Study shows better soil, potentially flavors from intercropping
- A new study tests whether hemp is an effective plant for intercropping between wine grapes to increase soil health and potentially add another cash crop to vineyards.
- Vintners planted hemp with other cover crops on a vineyard in New Zealand, and found that while hemp was a robust grower, it didn’t compete with grape vines for water, even in dry conditions.
- Surprisingly, the wine made from grapes grown near hemp had a delicious, complex flavor profile, but researchers say more tests are needed to see if hemp was the driving factor.
- The researchers plan to investigate further whether hemp is an effective plant for intercropping to improve vineyard soil health and carbon storage.

‘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.”
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.
Traditional healers push for recognition and licensing of age-old Himalayan practice
- Traditional healers from Nepal’s Himalayas are trying to preserve Sowa Rigpa, an ancient medicinal system based on ethnobotany, which has been gradually disappearing as youths move to urban areas and the species used in medicinal formulas are at risk.
- Sowa Rigpa includes traditional knowledge of the properties of hundreds of endemic species and local varieties of plants, fungi and lichens, as well as dozens of types of minerals.
- Two associations of Sowa Rigpa healers are trying to get the medicinal practice officially recognized by the Nepali government as a way to protect it, and are seeking official medical licenses for new practitioners.
- The healers, known as amchi, are partnering with a university, NGO and the government to further research, conserve and find potential substitutes for threatened plant and animal species used in Sowa Rigpa.
Nearly half of the world’s flowering plants face the threat of extinction, study says
- A new study estimates that nearly half of the world’s known flowering plants are threatened.
- Scientists built an AI model using plants they know are threatened or safe, then used it to estimate how many others are threatened as well.
- The research team hopes to get more plants included on the IUCN Red List, which helps protect threatened species from habitat loss.
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.
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.
Glyphosate leaves its mark even in protected areas of Brazil’s Cerrado
- A study found lichens dying as a result of exposure to glyphosate in an ostensibly protected area in Brazil’s Goiás state.
- Formed by interaction between fungi and algae, lichens are bioindicators of air quality.
- Glyphosate is the top-selling herbicide in Brazil and the world, used intensively in soybean, corn and sugarcane plantations; around 70% of pesticides sold in the country are applied in the Cerrado grassland biome.
- The study confirms the dispersion of the product into conservation areas from farmland, with aerial spraying a major factor for this so-called drift.
São Paulo nurseries bring the city’s rare and forgotten trees back to life
- São Paulo’s three municipal nurseries produce around 1.5 million native seedlings every year to green up the city.
- The Harry Blossfeld nursery alone produces 270,000 seedlings from more than 200 species of trees, 22 of which are threatened with extinction.
- By rescuing forgotten tree species, municipal nurseries have become spaces for science and the production of knowledge about the behavior of little-known native plants.
- Public landscaping helps recharge aquifers, combats heat islands, prevents flooding, attracts wildlife, improves air quality, reduces noise pollution, and contributes to city dwellers’ emotional and physical well-being.
Bangladesh survey records invasive alien plants threatening protected forests
- According to a survey, 44 exotic invasive plant species were recorded in five protected forests in Bangladesh. Of them, seven species were found to be harmful, with significant environmental impacts on protected forest areas.
- As a signatory of the Convention on Biological Diversity (CBD), the country is committed to protecting ecosystems and biodiversity of flora and fauna.
- To check the number and reduce the negative impacts of the identified alien invasive plant species on ecology and environment, the government has taken five strategic management plans.
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.
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.
First Nation and scientists partner to revive climate-saving eelgrass
- Seagrass meadows, of which eelgrass is a key species, are some of the most biodiverse and productive ecosystems in the ocean, and play a crucial role in sequestering carbon.
- But eelgrass is disappearing rapidly around the globe, and in Canada, questions remain about where exactly these meadows are distributed, and how effective they are at storing carbon.
- A collaborative project between marine biologists and Indigenous Mi’kmaq communities is attempting to answer these questions in eastern Canada while also restoring lost eelgrass meadows.
- The project could help with eelgrass’s long-term survival in the area, as researchers identify eelgrass populations that are more resilient to climate change, and communities work toward eelgrass conservation.
‘Lost’ Brazilian holly tree species found again after nearly 200 years
- After nearly 200 years without a confirmed sighting, a rare Brazilian tree species called the Pernambuco holly has been found in northeastern Brazil.
- The team located four trees, two male and two female, in a forest fragment near a sugarcane plantation in the metropolitan region of the city of Recife.
- The trees live in an area that was once Atlantic Forest, but now less than 7% of its original forest biome remains, mostly in small fragments.
- Researchers plan to search for more trees, protect the rediscovered site, and collect seeds for germination, but say these efforts will be costly.
It had to be a snake: New species from Peru named after Harrison Ford
- Scientists have described a new-to-science snake species from Peru’s Otishi National Park and named it after the actor Harrison Ford for his conservation advocacy.
- The pale yellowish-brown snake with black blotches was found in high-elevation wetlands and identified using genetic techniques.
- The team faced risks from illegal drug activity in the remote park area where the snake was found, cutting their survey short.
- Satellite data and imagery show several areas of forest loss throughout the park, which appear to have been caused by natural landslides. Still, some bear the hallmarks of human-caused clearing likely linked to coca cultivation and drug trafficking.
How seed networks across Brazil are helping to restore biomes
- In early June, a meeting of Redário — a group of seed networks from all over Brazil — brought together members of traditional peoples, NGOs and government agencies in the Chapada dos Veadeiros National Park.
- Seed networks are community organizations that have multiplied in the last decade in different Brazilian biomes to collect, trade and plant native seeds in degraded areas.
- They promote more inclusive ecological restoration as they generate income for traditional peoples and family farmers who preserve their territories.
- Brazil has signed international commitments planning to restore 30 million acres by 2030.
Study: More than 900 at-risk species lack international trade protections
- A recent study reveals concerning gaps in trade protections for the most at-risk animal and plant species.
- To identify potential gaps, researchers compared species on the IUCN Red List with those covered by the CITES, the global wildlife trade convention.
- Two-fifths of the species considered at risk due to international wildlife trade, 904 species, aren’t covered by CITES, the study found.
- The researchers suggest steps that the CITES committees can take to incorporate these findings, including both strengthening protections for overlooked species and relaxing trade controls for species that have shown improvement in their conservation status.
Should species be named after people? It’s up for debate.
- The practice of using eponyms, or scientific names based on real or fictional people, has been in place since the 1700s, but is a controversial and hotly debated topic.
- In a recent commentary, a group of scientists argue that eponyms perpetuate a negative legacy associated with imperialism, racism and slavery, and call for offensive names to be changed.
- Others say that changing names threatens the stability of nomenclature, would be costly and time-consuming to implement, and that those who regulate naming should refrain from making moral judgments, as there are no defined criteria for determining offensiveness.
- Researchers offer solutions to alter and improve naming practices including changing the codes that govern naming, implementing a stricter interpretation of the codes, establishing an international committee, or reforming the bodies that govern naming.
Bangladesh orchid losses signal ecological imbalance, researchers say
- Bangladesh has lost 32 orchid species from nature in the last hundred years out of 188 once-available species.
- Habitat destruction, overharvesting, and indiscriminate collection for sale in local and international markets cause the disappearance, researchers say.
- Considering the unique position of orchids in the ecosystem and their herbal, horticultural and aesthetic value, researchers consider this loss alarming.
Bangladesh ‘Village of Herbs’ profits from planting rather than cutting trees
- According to the World Health Organization, 88% of all countries are estimated to use traditional medicine; more than 40% of pharmaceutical formulations are based on natural products, and many landmark drugs originated from traditional medicine.
- According to the Bangladesh Agricultural Research Institute, there are 722 species of medicinal plants in Bangladesh.
- Locals who once cut down trees are now actively planting and cultivating medicinal trees. Large pharmaceuticals, Ayurvedic, and Unani medicine manufacturers collect raw materials from this market.
Blue carbon deserves a green light for the climate fight (commentary)
- Marine habitats like mangrove forests, seagrass meadows, salt marshes, and kelp forests cover just 0.2% of the ocean surface and provide shelter & food for myriad life forms while containing 50% of the carbon sequestered in marine sediments.
- Yet at a time when the world needs to keep carbon sequestered to mitigate the effects of climate change, about 35% of the world’s mangroves and 30% of all seagrass meadows have been lost or degraded.
- A new op-ed argues that the world should be moving to reverse these trends: “We are currently throwing away a golden opportunity to tackle the climate crisis, bolster sustainable fisheries and allow wildlife to thrive.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Philippines research offers hope for conserving enigmatic Rafflesia plants
- Rafflesia, flowering parasitic plants found only in Southeast Asian rainforests, are infamously difficult to study due to their rarity and small habitat ranges.
- With Rafflesia species edging closer to extinction due to habitat loss, botanists are working to better understand the genus and to develop methods that allow the plants to be propagated in labs and botanical gardens.
- Parallel research efforts from two teams led by Filipino scientists are yielding promising results in both understanding how Rafflesia function at the genetic level and in refining methods that will allow for ex situ cultivation.
Microbes play leading role in soil carbon capture, study shows
- Soil is a significant carbon reservoir, storing more carbon than all plants, animals and the atmosphere combined, making it crucial for addressing the climate crisis.
- Microbes, such as bacteria and fungi, are the primary drivers of carbon storage in soil, surpassing other soil processes by a factor of four, according to a new study in Nature.
- The efficiency of microbial metabolism plays a vital role in determining the amount of organic carbon stored in soils worldwide, according to the research, which also calls for improved soil carbon models for effective policies and climate solutions.
- Enhancing microbial efficiency can lead to increased carbon storage in soils, but further research is needed to understand how to achieve this.
To meet U.N. climate, biodiversity goals, 79% of plant cover must be saved, study
- A study suggests that approximately 79% of Earth’s remaining natural vegetation should be protected to meet the international goals set by the United Nations on climate, biodiversity and development.
- Vegetation plays a crucial role in purifying water, regulating the climate, supporting biodiversity, and stabilizing the soil, making its preservation essential for nature and people
- The study highlights the need to go beyond formal protections of wild places and address the ongoing depletion of natural vegetation due to intensive human land uses.
- Ensuring the land rights, security of tenure, and meaningful engagement of Indigenous peoples (who safeguard 80% of the planet’s biodiversity) and local communities is crucial for successful conservation efforts.
Bangladesh’s new red list of plants shows country has already lost seven species
- Bangladesh’s first-ever red list of plant species shows the country has lost seven species in the last century and now risks losing at least another five.
- Researchers involved in the assessments of the conservation status of 1,000 species cited climate change, pollution, deforestation, and poor management of protected areas as major drivers behind the ecological damage.
- The Bangladesh Forest Department is working to protect native plant species through large-scale planting efforts across the country.
Projects in Brazil’s Caatinga biome combine conservation and climate adaptation
- The Serra das Almas reserve in northeastern Brazil has benefited from sustained conservation measures that have turned cropland and pasture back into native Caatinga vegetation and allowed the return of wildlife.
- More than 800 animal and plant species are known to occur in the reserve, including the rare three-banded armadillo, a species that, until its sighting here last year, hadn’t been seen in Ceará state since 2008.
- The Caatinga Association, which owns and manages the Serra das Almas reserve, has encouraged the creation of more protected areas throughout the biome, providing support for 26 private reserves and three public conservation units, covering a combined 103,600 hectares (256,000 acres).
- Maintaining the Caatinga’s vegetation is crucial for securing water supplies for neighboring communities, and the association is supplementing that role in the face of a changing climate by providing water storage solutions to communities.
‘A psychedelic renaissance’: How hallucinogens can aid conservation
- Mind-altering substances from plants and fungi, such as ayahuasca, are having a moment in popular culture, but they’re also starting to gain attention from the medical and conservation communities.
- Famed ethnobotanist, conservation advocate and best-selling author Mark Plotkin joins the Mongabay Newscast to talk about what he dubs the “psychedelic renaissance” and how this moment can be a hook to inspire conservation.
- Many Amazonian plants and fungi have medicinal properties understood by traditional healers, but can also be frequently abused if applied improperly.
- Plotkin talks about the importance of protecting this traditional ecological knowledge, both for the responsible application of these plants, and for realizing their potential as a vehicle for conservation.
Mycorrhizal fungi hold CO2 equivalent to a third of global fossil fuel emissions
- A recent study estimates that more than 13 billion metric tons of CO2 from terrestrial plants are passed on to mycorrhizal fungi each year, equivalent to about 36% of global fossil fuel emissions.
- The study highlights the overlooked role of mycorrhizal fungi in storing and transporting carbon underground through their extensive fungal networks
- Researchers analyzed nearly 200 data sets from various studies that traced carbon flow and found that plants allocate between 1% and 13% of their carbon to mycorrhizal fungi.
- Understanding the role of mycorrhizal fungi is essential for conservation and restoration efforts, as soil degradation and the disruption of soil communities pose significant threats to ecosystems and plant productivity.
Soil carbon in urban parks important in fighting climate change, study shows
- A recent study shows that urban parks and green spaces throughout the world have a similar amount of carbon stored in their soils as in natural regions close to cities, which means urban green spaces can be important to global carbon sequestration and mitigating the potential effects of climate change.
- Soil microbes in urban green spaces play a vital role in carbon storage, but that carbon is also vulnerable to loss through microbial respiration in an increasingly warmer world; researchers emphasize the need for greater understanding of the soil microbiome in urban policies and planning.
- For context, Suriname has 93% forest cover nationwide and is often referred to as the world’s “greenest” country — but the capital city, Paramaribo, lacks a structural approach to urban greenery.
- Researchers conducted a project to promote a greener and more livable Paramaribo, with the aim of mitigating the effects of climate change and raising awareness among citizens.
Greater Mekong proves an ark of biodiversity, with 380 new species in a year
- Scientists described 380 new-to-science species from the Greater Mekong region of Southeast Asia between 2021 and 2022.
- Researchers working in Cambodia, Laos, Myanmar, Thailand and Vietnam identified 290 plant, 19 fish, 24 amphibian, 46 reptile and one mammal species, including a thick-thumbed bat, a color-changing lizard, and a Muppet-looking orchid.
- However, many of these species already face the threat of extinction due to human activity, prompting advocates to call for increased protection of their habitats by regional governments.
- The most urgent threats to the region’s wildlife and habitats include the construction of hydropower dams, climate change, illegal wildlife trade, and loss of natural habitats.
Overlooked and underfoot, mosses play a mighty role for climate and soil
- Mosses cover a China-size area of the globe and have a significant impact on ecosystems and climate change, according to a new study.
- Researchers conducted the most comprehensive global field study of mosses to date to quantify how soil moss influences soil and ecosystem services in different environments on all seven continents.
- Soil mosses can potentially add 6.43 billion metric tons of carbon to the soil globally, an amount equivalent to the annual emissions of 2.68 billion cars.
- Moss-covered soil offers several other benefits, including cycling of essential nutrients, facilitating faster decomposition, and reducing harmful plant pathogens.
Deforestation in Borneo threatens three endangered, endemic plant species
- The rampant deforestation for monoculture plantation and logging in western Indonesian Borneo has exacerbated the extinction risks of three plant species endemic to the island’s riparian lowland rainforests, a new study said.
- The researchers are calling for stricter protection of the forest fragments as a key conservation strategy for the three plant species and for further research to be done to better understand the species’ population status so as to improve their management.
- The island of Borneo, which is split between Indonesia, Malaysia and Brunei, has for the last few decades lost more than a third of its forests due to fires, logging, mining and industrial plantations, particularly oil palms.
Newly described leafless orchid in Sri Lanka named after a precious yellow sapphire
- A new leafless ground orchid found in a lowland wet zone forest in Sri Lanka has been named after a precious yellow sapphire as Gastrodia pushparaga, a gemstone commonly extracted from the same district.
- This is the third Gastrodia species found in Sri Lanka, after the 1906 identification of G. zeylanica and G. gunatillekeorum, described in 2020, 114 years later.
- The plant grows in Walankanda, a forest frontier in the island’s intermediate zone with unique characteristics that will likely make these plants susceptible to future climate change impacts earlier than other wet zone rainforest plants.
- Tea plantations being the main prompt for forest fragmentation in the area, an ambitious project aims to create an ecological land corridor through neglected tea estates, linking the forest where the orchid was first found with another fragmented forest patch.
Indigenous Comcaac serve up an oceanic grain to preserve seagrass meadows
- The Indigenous Comcaac community of northwestern Mexico is working to preserve eelgrass and promote the renaissance of the grain they obtain from it.
- Known as xnois, this grain from the Zostera marina seagrass was once a vital ingredient in Comcaac food, and was sustainably harvested without harming seagrass meadows.
- Current generations of Comcaac hope to revive the ancient traditions while preserving the seagrass meadows off the coast of their territory.
- Through a recent cultural festival, they showcase the versatility of xnois in both traditional and modern cuisine, from tortillas to energy bars.
Trees with edible leaves can boost human nutrition: New book, free download
- Tree planting is widely promoted as a solution to challenges ranging from climate change to biodiversity loss, desertification, and more.
- One less-appreciated benefit of growing trees is for their leaves for human nutrition, but a new book, “Trees with Edible Leaves: A Global Manual,” details more than 100 species whose leaves are highly nutritious.
- Trees are also much easier to grow than annual vegetables, being very simple to maintain once established, and benefit other crops when grown in agroforestry settings.
- Mongabay interviewed Eric Toensmeier, the author of this new resource, which is available as a free download.
Kew Gardens joins local partners to save tropical plants from extinction
- The U.K.’s Kew Gardens does far more than preserve and display 50,000 living and 7 million preserved specimens of the world’s plants; it also educates the public about the importance of plant conservation via its famous London facility.
- In 2022, Kew Gardens identified 90 plants and 24 fungi completely new to science. They include the world’s largest giant water lily, with leaves more than 3 meters across, from Bolivia; and a 15-meter tree from Central America, named after the murdered Honduran environmental activist Berta Cáceres.
- The institution is working actively with local partners in many parts of the world, and especially in the tropics, to save these species in-situ, that is, where they were found. When Kew can’t do this, it saves seeds in its herbarium, carrying out ex-situ conservation.
- Kew researchers, along with scientists from tropical nations, are also working together to ensure that local communities benefit from this conservation work. The intention is to save these threatened plants for the long term, helping slow the pace of Earth’s current extinction crisis — the only one caused by humans.
Amid global mezcal craze, scientists and communities try out sustainable plantations
- Mezcal, an increasingly popular Mexican liquor, has seen a 700% increase in production in the last ten years, leading to the over-harvesting of wild agave and the expansion of monoculture plantations which ecologists say is threatening endangered bat species and ecosystems.
- Scientists from universities across Mexico are researching how to develop sustainable organic plantations in five states that can meet rising global demand while also benefiting local communities.
- In one of the projects, they are testing over 45,000 thousand agave plants of two native species in agroecological systems to observe which practices best support their growth.
- Because few studies have been done on the environmental impacts of the booming industry, regional studies are needed, says a biologist.
‘War with weeds’ lacks ecological understanding and empathy (commentary)
- ‘Weeds’ are plants with special botanical and ecological attributes that allow their rapid establishment in disturbed areas, helping to reduce erosion of soils.
- Many weedy species have also proven their usefulness as medicines and food, going back several millennia. Wildlife, too, can benefit from such plants.
- Yet these plants are often the focus of a ‘war on weeds’ which is unfortunate and misguided, the author of a new book on the topic argues. “Can weeds be appreciated for their critical ecological roles? Can they be managed in situations where they may become problematic?” he asks.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Botanists are disappearing at a critical time
- The expansive field of botany could be facing a dearth of skilled experts due to a growing lack of awareness of plants, interest in studying them, and fewer educational opportunities to do so.
- Humans depend upon plants for basic survival needs, such as food, oxygen, and daily household products, but fewer students are receiving enough instruction to enable them to do much beyond basic identification.
- This lack of educational opportunities to study plants – and a general lack of interest in them – is leading to less ‘plant awareness’ and could endanger society’s ability to address existential problems like biodiversity loss and even climate change.
- The University of Leeds’s Sebastian Stroud joins the Mongabay Newscast to talk about his research highlighting this increasing lack of plant literacy, the consequences of it, and what can be done to turn it around.
At COP 15, biodiversity finance, Indigenous rights, and corporate influence
- Mongabay editor Latoya Abulu joins the Mongabay Newscast to discuss her visit to the United Nations conference on biodiversity in Montreal that occurred in December 2022.
- Latoya shares the details on the landmark Kunming-Montreal Biodiversity Framework, which nearly 200 nations agreed to, toward halting and reversing global biodiversity loss by 2030.
- While the historic agreement has been lauded as a victory, particularly for its inclusion of the acknowledgment of Indigenous rights, biodiversity experts, advocates and Indigenous leaders alike have reservations.
- Latoya speaks about all this as well as corporate influence over the final text, such as the inclusion of “biodiversity credits,” which also raise some concerns.
Top 15 species discoveries from 2022 (Photos)
- A resplendent rainbow fish, a frog that looks like chocolate, a Thai tarantula, an anemone that rides on a back of a hermit crab, and the world’s largest waterlily are among the new species named by science in 2022.
- Scientists estimate that only 10% of all the species on the planet have been described. Even among the most well-known group of animals, mammals, scientists think we have only found 80% of species.
- Unfortunately, many new species of plants, fungi, and animals are assessed as Vulnerable or Critically Endangered with extinction.
- Although a species may be new to science, it may already be well known to locals and have a common name. For instance, Indigenous people often know about species long before they are “discovered” by Western Science.
Hunting for future-proof marine plants in the acidic waters bathing a volcano
- The naturally acidic seawater near an underwater volcano in Italy mimic pH levels that according to worst-case climate projections will be common by the end of the century and beyond.
- Scientists are studying local seagrass and seaweed responses to the acidic conditions.
- One question is whether they could be used for restoration purposes in other places that may become more acidic in a not-so-distant future.
- Even so, some researchers point out that these carbon-sequestering marine plants face more immediate challenges from pollution, habitat degradation and warming waters that need addressing for restoration to succeed.
Illegal orchid trade threatens Nepal’s ‘tigers of the plant world’
- Roughly 500 orchid species grow in Nepal’s forests, including a rare pale purple beauty that attracts thousands of pilgrims each April.
- Orchids are among the most diverse and charismatic plant groups in the world, and they are threatened by illegal and unsustainable trade, largely for Ayurvedic and Chinese medicine.
- Kathmandu-based NGO Greenhood Nepal has a project that outlines key steps for government agencies to take in efforts to curb illegal and unsustainable trade in Nepal’s orchids.
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.
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.
Indigenous knowledge guides the conservation of culturally important plants
- The Karuk Tribe in northern California has traditionally managed plants for food, fiber, and medicine, but decades of fire suppression and climate change are threatening culturally important species.
- Researchers partnered with Karuk Tribe land stewards to understand how fire suppression and drought have affected the quality of four plants central to their food security and culture.
- In this long-term collaborative study, Indigenous Knowledge expands on western science methods, assessing the ecological health of plants and their cultural usefulness.
In Chile, drought and human expansion threaten a unique national park
- La Campana National Park in Chile is home to threatened species of plants and animals, many found nowhere else.
- The region has been suffering a 12-year drought, and in spite of rains this year, experts say it’s too early to say whether the climate trend has been reversed.
- The park also faces pressure from expanding farmland and urbanization, including the conversion of native vegetation to fruit monocultures, and the encroachment of domestic animals that can spread disease to wildlife.
Amid conflict and chaos, a reforestation project surges ahead in Haiti
- An important reforestation project is forging ahead in Haiti, despite the nation’s economic and political upheavals.
- Reforesting 50 hectares (124 acres) with native plants this year in Grand Bois National Park, the NGO Haiti National Trust (HNT) is working closely with local communities to ensure the restoration project’s long-term survival.
- On an island buffeted by governance woes, severe deforestation and climate change, reforestation can save lives by mitigating the impacts of extreme rain events, droughts and hurricanes, and even reduce the risk of landslides caused by earthquakes.
- If ongoing funding can be secured, the group hopes to continue replanting efforts into the future with larger restoration goals.
A flying robot swoops in via Quebec to save endangered plants in Hawai‘i
- Surveying and collecting rare plant species that grow on steep cliffs has been a risky affair for scientists and conservationists for hundreds of years.
- The world’s first aerial sampling system that comprises a robotic arm suspended from a drone is trying to solve the problem in Hawai‘i.
- Conservationists control the Mamba robotic arm via remote control to identify and cut samples from rare plant species.
- The tool has enabled scientists to collect endangered species from vertical terrain and grow them in nurseries.
Meet the Millennium Forest: A unique tropical island reforestation project
- A two-decade reforestation project on the tropical island of St. Helena in the southern Atlantic Ocean has not only restored trees found nowhere else in the world, but has also involved nearly every member of the island community in the effort.
- The Millennium Forest, as it’s called, has struggled with invasive species and irregular funding, but has still managed to thrive, adding new plant species — several of them threatened and two thought to have gone extinct. The growing forest is attracting animal species to its habitat, including St. Helena’s only endemic bird.
- Ocean islands pose special challenges for forest restoration, since many plant species evolved in isolation on remote islands, and saw drastic population crashes to the point of extinction, or near-extinction, when people and invasive species arrived.
- As a result, island reforestations typically can’t match original forest composition, but must mix both native and non-native species. The Millennium Forest project has now become a legacy that the current generation is handing down to upcoming ones, according to project founder Rebecca Cairns-Wicks.
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.
Tuning in to the world of nonhuman sound: Q&A with author Karen Bakker
- “The Sounds of Life” is a new book by University of British Columbia geography professor Karen Bakker that explores our understanding of nonhuman sound.
- Through the stories she has gathered from around the world, Bakker reveals how new technology has given us “a planetary hearing aid,” both to better understand how nonhuman life uses sound and the ways in which these sounds can help monitor and protect species.
- Bakker also investigates the role of traditional knowledge and deep listening to help researchers tune in to the sounds around us.
- Mongabay spoke with Karen Bakker in September.
Documenting Nepal’s plant-based medical tradition: Q&A with Ram Prasad Chaudhary
- Ram Prasad Chaudhary is an ethnobotanist who for decades has studied how various communities throughout Nepal use medicinal plants and pass on this knowledge.
- One pattern he’s noticed is that communities living at higher altitudes tend to make more use of herbal remedies than those living on the plains, with the latter having easier access to Western medicine — a situation he calls ironic.
- With younger generations of Nepalis increasingly viewing ethnobotanical traditions as superstition, Chaudhary says it’s imperative to instill in them the belief that the practice is based on centuries of knowledge generation.
- He also points to the case of China, where the practice of both Western and traditional medicine is complementary rather than competing, saying this is “the best way to go about it.”
Protecting global forests with a limited budget? New study shows where and when to start
- A newly published study identifies where and when to protect forests with the goal of protecting the maximum number of additional plant species over a 50-year period.
- The greatest return on investment would come mostly from forest conservation within Melanesia (around New Guinea), South and Southeast Asia, the Anatolian peninsula (Turkey), northern South America and Central America.
- Many of the highest-conservation-priority areas fall within lower-income tropical countries, so substantial international funding is likely needed to conserve and restore forests.
- An estimated 80% of the planet’s biodiversity lies within Indigenous peoples’ territories, and securing Indigenous communities’ land rights can be an equitable, low-cost, and effective way to protect the environment.
Between six ferns: New tropical fern species described by science
- Researchers have described six species of ferns new to science from the tropical forests of Panama, Colombia, Ecuador and Peru, all in the genus Danaea.
- The ferns range in height from 20 centimeters to two meters (8-79 inches), and some of them are very common locally; two species are assessed as threatened with extinction.
- Most of the preserved specimens used to describe the new Danaea species were collected decades ago, some as far back as the 1800s.
- Scientists unearthed the specimens from herbarium samples while researching patterns of biodiversity in the Amazon.
Is invasive species management doing more harm than good? (commentary)
- Conservationists may be thwarting their own efforts, as well as causing harm to wildlife, in their battle against invasive species, a new op-ed argues.
- In numerous cases, non-native species have been shown to benefit wildlife, while their management – from toxic chemicals to culling – may be causing more harm than good.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Beyond boundaries: Earth’s water cycle is being bent to breaking point
- The hydrological cycle is a fundamental natural process for keeping Earth’s operating system intact. Humanity and civilization are intimately dependent on the water cycle, but we have manipulated it vastly and destructively, to suit our needs.
- We don’t yet know the full global implications of human modifications to the water cycle. We do know such changes could lead to huge shifts in Earth systems, threatening life as it exists. Researchers are asking where and how they can measure change to determine if the water cycle is being pushed to the breaking point.
- Recent research has indicated that modifications to aspects of the water cycle are now causing Earth system destabilization at a scale that modern civilization might not have ever faced. That is already playing out in extreme weather events and long-term slow-onset climate alterations, with repercussions we don’t yet understand.
- There are no easy or simple solutions. To increase our chances of remaining in a “safe living space,” we need to reverse damage to the global hydrological cycle with large-scale interventions, including reductions in water use, and reversals of deforestation, land degradation, soil erosion, air pollution and climate change.
Mahogany, a pillar of the rainforest, needs support (commentary)
- Mahogany has been the wood of choice for furniture and cabinetry for centuries, and is highly sought by guitar makers for its strength and resistance to changes in humidity and temperature.
- But when it was last assessed in 1998, biologists categorized the tree as “vulnerable to extinction” — the same category as cheetahs and polar bears, iconic species that are well known to be threatened.
- Economics must play a leading role in protecting mahogany, and all the species that depend on it, if we are to turn the tide on its decline and slow tropical deforestation, a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Can wonder plant spekboom really bring smiles back to sad South African towns?
- Botanists are working on an ambitious project to restore 1 million hectares (2.5 million acres) of degraded land in South Africa that were previously covered by thickets of the indigenous succulent spekboom (Portulacaria afra).
- Farmers have stripped the land of its native thicket over the course of decades of commercial agriculture and livestock keeping, and following extended droughts, it’s now turning to desert.
- Spekboom, much praised for its ability to sequester carbon, is not only a resilient native plant, but its growth naturally promotes the recovery of other species.
- Carbon credits are one promising source of funding for restoration that could prove profitable for landowners and workers, though some critics say planting spekboom as an offset lacks a scientific basis.
Legal and illegal cannabis: A cause for growing environmental concern
- Legalization of cannabis for medicinal and recreational use is an expanding global trend in the U.S. and globally, while the illicit market continues to feed large swaths of demand.
- Both the legal and illegal markets are linked to environmental challenges such as freshwater use, land-use change, toxic and nutrient pollution, and climate change-contributing CO2 emissions.
- Emerging legal cannabis businesses in the U.S. are subject to strict regulation, but many operate in ways that can contribute to environmental harms.
- While the scope of damage from booming legal growing operations is now being better assessed, the impacts of illicit clandestine operations remain mostly undetermined.
Efforts bloom to save southern Brazil’s last butiá palm groves
- Targeted by the expansion of agriculture and urbanization, the last butiá palm landscapes continue to cling to life in Brazil’s southern state of Rio Grande do Sul.
- Of the 21 known butiá species in South America, 19 occur in Brazil — all of them under threat.
- An experimental project proposes a rotating cattle management method in butiá areas as a way to protect the shoots of the young palms from being eaten.
- Other efforts to protect the trees include creating a tourism circuit linking butiá groves in Brazil, Argentina and Uruguay, and publishing a book of butiá fruit recipes.
Indigenous village harvests seeds to slow deforestation in Brazil’s Cerrado
- Mato Grosso’s Cerrado forest in Brazil is supposed to be protected with set asides when logged for new croplands and pastures. However, farms often get away with protecting less than they’re supposed to.
- In the village of Ripá, Indigenous Xavante people make expeditions for harvesting fruit with seeds for replanting forests, helping to repair some of the damage and supplement their income.
- Ripá and another two dozen Indigenous communities in Mato Grosso sell their harvest to Rede de Sementes do Xingu (RSX), a wholesaler that, since 2007, has sold or given away enough seeds to replant 74 square kilometers (about 29 square miles) of degraded land.
- This story was produced with support from the Pulitzer Center.
Newly described plant is latest fruit of Sri Lankan botanists’ collaboration
- Researchers in Sri Lanka have described a new-to-science species of flowering plant, categorizing it as critically endangered because of its small and declining population and restricted range.
- Impatiens jacobdevlasii is named in honor of Dutch botanist Jacob de Vlas, co-author of a series of illustrated guides on the more than 3,000 known flowering plants of Sri Lanka.
- Sri Lanka is among the six global hotspots of impatiens plants, but many of its endemic species are threatened with extinction, with one considered possibly extinct after not having been seen in nearly a century.
- The new discovery also highlights the spirit of collaboration among a young cohort of Sri Lankan botanists, whose work is inspiring greater interest in the island’s plant life, and a growing body of new discoveries.
To gauge impact of nitrogen pollution, Sri Lanka project looks to lichens
- Researchers in Sri Lanka are studying how atmospheric nitrogen pollution affects lichens as a proxy for vegetation, to better understand how plants and soil are coping with the increasing volumes of nitrogen humans are releasing into the atmosphere.
- South Asia is a global hotspot for atmospheric nitrogen pollution, caused mainly by fertilizer emissions, as well as the burning of fossil fuels.
- Ammonia and nitrous oxide, the “reactive” forms of nitrogen in the atmosphere, are up to 300 times more powerful greenhouse gases than carbon dioxide, but also have direct impacts on human health, plant growth, and soil nutrient balance, with potentially severe impacts on food security.
- A U.N.-sponsored campaign, launched in Colombo in 2019, aims to halve nitrogen waste by 2030.
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.
Asia’s troubled trees need better conservation to reach restoration goals: Study
- South and Southeast Asia’s 19,000 tree species form the foundations of some of the world’s most biodiverse rainforests, as well as provide irreplaceable ecosystem services and underpin the livelihoods and diets of hundreds of millions of people.
- However, roughly three-quarters of the land deemed most important to protect regional tree diversity lies outside of protected areas, according to a new study that evaluates the distribution and threats facing 63 native tree species.
- The findings question whether countries will be able to fulfill their ambitious forest restoration targets; in particular, the researchers are concerned that crucial seed resources that could support reforestation efforts are being lost.
- The researchers recommend a more coordinated approach to conservation planning within the region, including improved cross-border collaboration and a holistic, landscape approach that integrates trees into production systems outside of protected areas.
Warming could nip Southeast Asian forests’ mass flowering in the bud, study finds
- Synchronous mass flowering is one of the most spectacular but least-understood phenomena in Southeast Asia’s tropical rainforests; crucially, scientists know very little about how flowering events might be affected by climate change.
- A new study looking at historical tree flowering in Malaysia has found that between 1976 and 2010, the proportion of flowering and fruiting species decreased as temperatures began to increase through that period.
- They also used models to predict future responses to climate change, finding that a rise of 1.2°C (2.2°F) in average global temperatures by the year 2100 could halve the flowering probability of Dipterocarp trees, an ecologically and economically important tree family in Southeast Asia.
- The researchers say we will likely see shifts in tree species composition in forests as those adapted to climate change are outcompeted by more adaptable species.
They outlived the dinosaurs, but Brazil’s araucaria trees might not survive humans
- The araucaria tree of Brazil’s Atlantic Forest could go extinct within the next 50 years due to permissive state policies allowing them to be cleared.
- While the species is listed as critically endangered, and there’s a ban on illegal logging of araucaria, the state governments of Paraná and Santa Catarina states still allow them to be felled in the thousands for public works projects.
- Araucaria forests today occupy just 2% of their historic range, scattered in fragments of forests measuring just 3,600 km2 (1,400 mi2).
- The species has been around for more than 200 million years, surviving the mass extinction that wiped out the dinosaurs, but could meet its own doom thanks to human-driven climate change.
Climate crisis forecasts a fragile future for wildflowers and pollinators
- A first-of-its-kind experimental study has found that climate change reduces the abundance of wildflowers and causes them to produce less nectar and fewer and lighter seeds.
- These changes also impact pollinating insects visiting the flowers: they have to visit more flowers, more frequently, to gather the required food.
- Fewer flowers imply reduced reproductive fitness in plants, as well as fewer food resources for invertebrates that rely on these plants for food, habitat and shelter.
- Overall, climate change may disturb the composition of wildflower species and their pollinators, impacting agricultural crop yields, researchers say.
‘Right moon for fishing’: Study finds gravitational impacts on plants, animals
- A recent review of the scientific literature shows that the gravitational forces that cause the tides are also associated with the rhythms of organisms such as plants, crustaceans and corals.
- Researchers say gravitational cycles are not being accounted for in scientific experiments that otherwise control for various environmental factors in the laboratory.
- In the field of gravitational effects, many practices that are repeated out of popular wisdom, such as the best time to cut wood or plant crops, still don’t have scientific backing.
‘We have a full pharmacopoeia of plants’: Q&A with Māori researcher Nicola Macdonald
- Aotearoa New Zealand’s green-lipped mussel industry provides a relatively sustainable source of animal protein, but the plastic ropes used to catch mussel larvae are a source of marine plastic pollution.
- Researchers are using mātauranga (Māori traditional knowledge) and Western science to work out whether natural fiber ropes, made from native species traditionally used by Māori, could provide a suitable and biodegradable alternative.
- Mongabay spoke with Indigenous researcher Nicola Macdonald about the research process, the findings so far, and the team’s hopes for helping create a more sustainable aquaculture industry.
‘No planet B’: Groups call for $60bn increase in annual biodiversity funding
- A group of international conservation and environmental organizations is calling on wealthy countries to provide an extra $60 billion in funding a year to protect the planet’s species.
- They argue that the amount compensates for the toll exacted on biodiversity by international trade, which largely benefits rich nations.
- At a March 1 press conference, representatives of the organizations said the inclusion of Indigenous communities, known to be “nature’s best stewards,” would be critical, and they advocated for the bulk of the financing to be in the form of grants to these communities and other “grassroots” organizations.
South America hosts nearly half of 9,000 tree species unknown to science
- The most comprehensive survey of Earth’s tree life has just been published, showing that there are some 9,000 species that scientists still haven’t described.
- Nearly half of these unknown trees are found in South America, which in turn accounts for 43% of the estimated 73,000 trees found on Earth, according to the study.
- Almost 150 researchers from across the globe collaborated on the study, which increases the previous estimate for total tree species by 14%.
- The study authors say the unidentified species are mostly rare and more vulnerable to the risk of extinction, hence there’s an urgent need to implement stricter protection and enforcement of environmental laws.
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.
Indonesian research center for medicinal plants displaces incense harvesters
- Incense harvesters in Indonesia’s North Sumatra province say the construction of a new center for research into medicinal plants threatens their livelihoods.
- The government says the center will boost Indonesia’s food and drug security, and maximizing the economic potential of Indonesia’s wealth of medicinal plants.
Community project helps Kenya aim for climate goals one mangrove tree at a time
- Along Kenya’s southeastern coast, three communities are restoring 460 hectares (1,137 acres) of the Vanga mangrove forest to meet the country’s emission reduction targets, provide a buffer against natural disasters, and support fishing livelihoods.
- The Vanga Blue Forest project has planted more than 1,000 native mangrove trees since it started in 2019, and aims to work with neighboring communities in Tanzania to restore mangrove forests along 140 kilometers (87 miles) of the East African coastline.
- The early stages of the project were a series of trial and error to achieve successful reforestation, as previous efforts a decade earlier had only a 10% survival rate among the 750,000 trees planted.
- The project is involved in the international carbon trade market and has so far sold $44,433 of carbon credits by accumulating 5,023 metric tons of carbon above ground.
Not your ordinary houseplant: World’s tallest begonia found in Tibet
- While surveying in the warm and rainy forests of southern Tibet, researchers spotted a begonia twice as tall as a person.
- The new species, which they named Begonia giganticaulis, is the tallest begonia in the world.
- Because fewer than 1,000 individual plants are estimated to live in the fragmented forest habitat, the species has been classified as endangered.
- China is home to some 300 begonia species, many of which are illegally collected and overharvested for ornamental or medicinal use, a trend driven by increased internet commerce.
Top 15 species discoveries from 2021 (Photos)
- Science has only just begun to find and describe all of the species on Earth; by some estimates, only 20% have been described.
- This year, Mongabay reported on newly described species from nearly every continent, including an Ecuadoran ant whose name broke the gender binary, an acrobatic North American skunk, an Australian “killer tobacco,” a fuzzy orange bat from West Africa, tiny screech owls from Brazil, and more.
- Though a species may be new to science, that doesn’t mean it has not yet been found and given a name by local and Indigenous communities.
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.
Fighting climate change is a dirty job, but soils can do it | Problem Solved
- The Earth’s soil stores nearly three times as much carbon as all plants, animals and the atmosphere combined, researchers say.
- However, unchecked deforestation, modern industrialized agriculture, the failure to recognize Indigenous land rights, and the continued extraction and burning of fossil fuels are all putting our crucial carbon sinks in the tropics and subarctic permafrost at risk of releasing much of that carbon.
- Experts agree that protecting soil is key to mitigating climate change, and to avoid breaching delicate planetary boundaries that are necessary to sustain human life on the planet.
- Doing so means fundamental shifts in how we grow our food, conserve and restore forests, and swiftly reduce our use of fossil fuels.
Indonesian couple stages ‘ecological wedding’ in hopes of inspiring others
- An increasing number of Indonesian couples are incorporating tree planting into their weddings, either as part of the ceremony or handing out samplings as souvenirs.
- Several towns and villages have adopted local regulations that require marriage applicants to plant a given number of trees as a requirement for getting married.
- The government has an ambitious goal of not just halving the deforestation rate over the next three decades, but also reforesting 10.6 million hectares (26.2 million acres) of land by 2050.
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.
Follow the butterfly: Rediscovery of ‘extinct’ plants highlights Sri Lanka’s new red list
- The latest edition of Sri Lanka’s red list of native plants shows that nearly half of the assessed species are threatened with extinction, a higher number than in the previous edition from 2012.
- There was some good news, however, with three of the five plants assessed as extinct in 2012 being rediscovered under serendipitous circumstances.
- The number of critically endangered plants considered possibly extinct because they haven’t been seen in a century has gone down to 128 from 170, thanks in large part to sleuthing by amateur botanists and social media.
- Much of the work compiling the red list was done by a group of young field botanists, who are riding a wave of enthusiasm among citizen scientists keen to study plants.
New Philippine corpse flower is phallic-shaped, funky smelling — and nearly extinct
- A maroon plant with a small, phallic-shaped flower and a putrid odor has been identified as a species new to science, Amorphophallus minimus.
- The plant was first collected in 2019 by a team of foresters conducting a biodiversity study in Pantabangan-Carranglan Watershed Forest Reserve in the Philippines’ Nueva Ecija province.
- Due to threats including logging and increasing human settlement in its sole known habitat, researchers have recommended the plant be listed as critically endangered.
A ‘sleeping beauty’ awakens to join Sri Lanka’s list of endemic plants
- A new species of flowering plant has been described from Sri Lanka’s Peak Wilderness rainforest, part of the Strobilanthes genus of plants that put on spectacular blooming displays periodically.
- Sri Lanka has 33 known Strobilanthes species, 27 of which are found nowhere else on Earth.
- The newly described species, Strobilanthes medahinnensis, was first spotted in 2015 by botanist Nilanthi Rajapakse, who returned to the same spot over the course of the next five years to wait for the plant to finally bloom.
- The genus is understudied, in part because its flowering cycle can take up to 12 years; at the same time, 21 of the Sri Lankan species are threatened with extinction.
A bouquet of discovery: Three new orchid species described from Ecuador
- Three new orchid species from the evergreen montane forests and shrublands of the Ecuadoran Andes have been described by scientists.
- Two of the new orchids have been preliminarily assessed as critically endangered according to IUCN Red List criteria.
- All three of the new-to-science species are in the genus Lepanthes, an extremely diverse group that boasts an estimated 1,100 species.
- Researchers found the flowers while studying plant-hummingbird interactions in cloud forests with different levels of disturbance. Ecuador is one of the most biodiverse places on Earth, where the interactions between many species have not yet been studied.
Underwater gardeners restore seagrass meadows to keep oceans healthy
- The more than 70 known species of seagrass play a key role in helping mitigate climate change by sequestering large amounts of carbon, as well as providing habitats for fish and invertebrates.
- But their importance in maintaining healthy oceans has long been overlooked, with seagrasses threatened by anthropogenic activities such as destructive fishing and water pollution, often to the extent that they can’t self-recover.
- Several initiatives around the world are trying to restore seagrass meadows, including an ongoing project off the coast of Wales in the U.K., and a successful one around the coastal bays of Virginia.
- Seagrasses are important nurseries for a rich diversity of marine life, including commercially important fish, which means their loss threatens the food security of many communities that depend on these fisheries.
Scientists look to wheatgrass to save dryland farming and capture carbon
- Intermediate wheatgrass is an imported grain that has been grown in the U.S. Great Plains and Intermountain West since the 1930s; but could it be used in marginal fields in dryland areas?
- Kernza, an intermediate wheatgrass bred by the Land Institute, is being planted in eastern Wyoming, where researchers from the University of Wyoming are uncovering whether the crop can help farmers stabilize and bolster their soils, while providing a profitable crop.
- Planting perennial crops, like Kernza, can help soil health and stability, retain moisture, and cut down on planting costs and greenhouse gas emissions from annual plantings.
Mexico devises revolutionary method to reverse semiarid land degradation
- Land degradation is impacting farmlands worldwide, affecting almost 40% of the world’s population. Reversing that process and restoring these croplands and pastures to full productivity is a huge challenge facing humanity — especially as climate change-induced drought takes greater hold on arid and semiarid lands.
- In Mexico, a university-educated, small-scale peasant farmer came up with an innovative solution that not only restores degraded land to productivity, but also greatly enhances soil carbon storage, provides a valuable new crop, and even offers a hopeful diet for diabetics.
- The process utilizes two plants commonly found on Mexico’s semiarid lands that grow well under drought conditions: agave and mesquite. The two are intercropped and then the agave is fermented and mixed with the mesquite to produce an excellent, inexpensive, and very marketable fodder for grazing animals.
- The new technique is achieving success in Mexico and could be applied to global degraded lands. Experts with World Agroforestry warn, though, that agave and mesquite are highly invasive outside their region, but suggest that similar botanical pairings of native species are potentially possible elsewhere.
New species of “killer tobacco” found at Australian truck stop
- Found at truck stop in Australia, Nicotiana insecticida is the first wild tobacco species reported to kill insects.
- The new tobacco does not appear to be carnivorous, but rather uses its sticky hairs to trap insects and protect itself from being eaten.
- This sticky killer is one of seven newly named species of Nicotiana (wild tobacco) from Australia’s harsh, arid regions.
- “The fact that we have only now found it,” said one of the researchers,“means that there are probably a lot more similarly interesting species out there to be found.”
Soil and its promise as a climate solution: A primer
- We know that soil feeds plants, but do we know how it got there in the first place? Soil forms via the interaction of five factors: parent material, climate, living beings, a land’s topography, and a “cooking” time that occurs on a geologic scale. Variations in these 5 factors make the world’s soils unique and extremely diverse.
- Soil acts as a carbon sink in the global carbon cycle because it locks away decomposed organic matter. But deforestation, various agricultural practices, and a changing climate are releasing it back into the atmosphere and oceans as carbon dioxide, resulting in an imbalance in global carbon budgets
- Tropical soils and permafrost hold the most soil carbon out of other biomes, making them conservation and research priorities in soil-centered climate solutions.
- Reforestation of previously forested lands is a viable solution to return carbon belowground, but it is not a fix-all. Changing industrial agricultural practices and giving high-carbon storage areas conservation status are key steps toward harnessing the soil’s carbon storage power.
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.
Scientists call for solving climate and biodiversity crises together
- A new report from United Nations’ Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) highlights the importance of confronting climate change and biodiversity loss together.
- Global climate change and the unprecedented loss of species currently underway result from a similar suite of human-driven causes, the report’s authors write.
- As a result, solutions that take both issues into account have the best chance of success, they conclude.
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.
A novel tree nursery gives the Caatinga a fighting chance against desertification
- Nearly half of the Caatinga, the only exclusively Brazilian biome, has been destroyed and 13% of its territory has already been lost to desertification.
- A project at Rio Grande do Norte Federal University is using PVC pipes to lengthen and accelerate root growth in native plant species that have trouble drawing water from degraded soil.
- Previous restoration methods in the Caatinga resulted in mortality rates near 70% after transplant, but this new method reverses that figure, raising survival rates to 70%.
The key to averting environmental catastrophe is right beneath our feet
- Billions of years ago, the first soils served as a cradle for terrestrial life. Today, the land beneath our feet underpins a multitrillion-dollar, global agricultural industry and provides food for nearly 8 billion humans, along with countless wild and domestic species. But soils are in global crisis.
- We are now living in the “danger zone” for four of the nine planetary boundaries: climate change, biodiversity, land-use change, and biogeochemical flows. All four are intimately linked to soil health. Soils hold 80% of all the carbon stored on land.
- Deteriorating soil health is already gravely impacting lives and livelihoods. Land degradation due to human activities costs around 10% of global gross product. When combined with climate change effects, soil degradation could reduce crop yields by 10% globally by 2050.
- There is an inevitable delay between recognizing global problems and enacting solutions, and seeing the resulting boost to ecosystem services. That’s why we must act now if we are to leverage soil ecosystems in the fight against disastrous global environmental change.
Sri Lanka to ban palm oil imports, raze plantations over environmental concerns
- Sri Lanka has imposed a ban on palm oil imports and ordered oil palm plantations in the country to be replaced with rubber trees and other crops over the next decade, citing adverse environmental and social impacts.
- The decision is based on recommendations from a 2018 report by a panel of environmental experts, who linked oil palm plantations to soil erosion and the drying up of water sources.
- Unlike in other countries where the crop is grown, oil palms aren’t a driver of deforestation in Sri Lanka; instead, they’ve replaced rubber plantations, which host a higher level of biodiversity and provide more jobs for locals.
- Another concern is that oil palm is becoming an invasive species, occurring in the wild in a forest reserve, with as-yet-unknown impacts on native flora and fauna.
‘Profound ignorance’: Microbes, a missing piece in the biodiversity puzzle
- Researchers are certain that human activity has resulted in a decline in plant and animal species. But a huge unknown remains: what impacts have human actions —ranging from climate change, to ocean acidification, deforestation and land use change, nitrogen pollution, and more — had on the Earth’s microbes?
- A new paper poses this significant question, and offers a troubling answer: Science suffers from “profound ignorance” about the ways in which microbial biodiversity is being influenced by rapid environmental changes now happening on our planet.
- Researchers are supremely challenged by the microbial biodiversity question, finding it difficult to even define what a microbe species is, and uncertain how to effectively identify, analyze and track the behaviors of microbes on Earth —microorganisms estimated to be more numerous than stars in the known universe.
- We do know microbes play crucial roles — helping grow our food, aiding in the sequestering and release of soil carbon, curing and causing disease, and more. One thing researchers do agree on: knowing how human activities are influencing the microbial world could be very important to the future of humanity and our planet.
Madagascar: Businesses drive disappearance of a wetland ‘reed forest’
- Lake Alaotra and its surrounding marshes are Madagascar’s largest wetland, a Ramsar Site that is home to globally significant biodiversity.
- Despite layers of legal protection and conservation programming, around 850 hectares (2,100 acres) of marsh disappear each year to make way for rice cultivation, much of it perpetrated by businesses.
- Local people are keenly feeling the lake’s decline, though, and a commitment to protecting it, along with some success stories, persist in pockets around its shores.
- The government is implementing a zero-tolerance campaign against illegal environmental destruction, but it remains to be seen whether this can reduce the lawlessness and impunity enough to safeguard the lake.
Study sounds latest warning of rainforest turning into savanna as climate warms
- A recent study from Brazil shows that heat stress is disrupting a critical component of photosynthesis in tree species found in the Amazon and Cerrado belt.
- Leaves heat up faster than the ambient air, and sufficiently high temperatures can cause irreversible damage to them and endanger the tree.
- The area has become hotter in recent decades and faced increasingly intense heat waves, fueled not just by global warming but also local deforestation.
- Tropical forests could look more and more like deciduous forests or savannas in the future, which are better adapted to deal with higher temperatures, the study found.
Hope blooms for an ‘extinct’ Sri Lankan tree that reemerged under threat
- The rediscovery of a Sri Lankan legume tree (Crudia zeylanica) in 2019 was rare good news of a species still surviving despite being declared extinct years earlier.
- But that tree is now threatened by a road project, prompting an outcry from conservationists, the general public, and even Buddhist monks, who anointed it in a ritual meant to discourage anyone from cutting it down.
- There’s still hope for the species, however, with botanists finding C. zeylanica specimens in six other locations and managing to germinate its seeds in a lab.
- The botanist responsible for the tree’s rediscovery, Himesh Dilruwan Jayasinghe, also rediscovered two other plant species declared extinct in Sri Lanka’s 2012 red list; an update to the red list is due in the next few weeks.
In Japan, scientists look to the past to save the future of grasslands
- Ecologists in Japan recorded several rare and endangered plant species in old grasslands that are not present in younger ones, mirroring findings from other continents that highlight the rich biodiversity of these landscapes.
- Grasslands face growing threats from humans on a global scale, especially land use change like agriculture and urban growth.
- But some human interventions have had a beneficial effect on biodiversity conservation in Japan, such as the maintenance of ski runs, which provide a safe haven for many of the plant species and pollinators that keep grassland ecosystems healthy.
- The study’s lead author says declining interest in skiing among Japanese may threaten the existence of these ancient grasslands.
Big dream: NGO leads in creating 1,615-mile Amazon-Cerrado river greenbelt
- The Black Jaguar Foundation plans to reforest 1 million hectares (2.4 million acres) along Brazil’s Araguaia and Tocantins rivers in the Amazon and Cerrado biomes. The 2,600 kilometer (1,615 mile) long natural corridor will require the planting of around 1.7 billion trees. Tens-of-thousands have already been planted.
- This natural corridor will be established on private lands, and it will have dual ecological and economic goals, resulting in both land conservation and sustainable agroforestry production. It would cross six Brazilian states (Goiás, Mato Grosso, Mato Grosso do Sul, Tocantins, Pará and Maranhão).
- BJF is well funded and well organized, so the greatest barriers to accomplishing the NGO’s goals are many initially resistant rural property owners who need to be sold on the economic benefits of the green corridor. 24,000 privately owned lots are included in the planned green corridor.
- “Brazil has a huge liability in degraded areas, and the BJF [green corridor] initiative is a huge outdoor laboratory for ecosystem restoration in the center of the country, in the agricultural frontier region,” said one researcher.
Fruit-eating, seed-pooping animals can help restore degraded forests
- Restoring degraded forests can be expensive and complicated, but Brazilian researchers may have a simple technique to add to the restoration toolbox: enlisting fruit-eating animals to spread seeds.
- A new study shows that many species of mammals and birds will consume seeds inserted into fruits at feeders and then excrete the seeds over wide areas.
- This novel proof-of-concept study highlights the importance of plant and animal interactions to restore the natural ecology of forests people have destroyed or degraded.
Protesters hold back military takeover of Balkans’ largest mountain pasture
- A 2019 decree by the government of Montenegro sets forth the country’s intention to set up a military training ground in the highland grasslands of Sinjajevina in the northern part of the country.
- But the pastures of Sinjajevina have supported herders for centuries, and scientists say that this sustainable use is responsible in part for the wide array of life that the mountain supports; activists say an incursion by the military would destroy livelihoods, biodiversity and vital ecosystem services.
- A new coalition now governs Montenegro, one that has promised to reevaluate the military’s use of Sinjajevina.
- But with the country’s politics and position in Europe in flux, the movement against the military is pushing for formal designation of a park that would permanently protect the region’s herders and the environment.
Tropical forests can take the heat, study finds. Dryness? Not so much
- Researchers simulated extreme global warming conditions for tropical forests in the Biosphere 2 dome in the Arizona desert, cranking up the temperature to 40°C (104°F).
- To gauge the trees’ resilience, they looked at how well they continued to photosynthesize, and found that they could do so up to 38°C (100°F), which is 10°C (18°F) warmer than the average temperature in tropical forests today.
- However, the enclosed dome helped maintain humidity levels, whereas real-world warming would lead to drier air, and therefore greater loss of water from plants through transpiration.
- The researchers say the study nevertheless provides relevant information on the main threats to these ecosystems: the combination of a warmer world and a drier climate.
Restaura Cerrado: Saving Brazil’s savanna by reseeding and restoring it
- The Cerrado is Brazil’s second largest biome, and the most biodiverse tropical savanna in the world. It is of vital importance for Brazil’s watersheds, for global biodiversity, and is an important but undervalued carbon stock.
- But in recent decades, half of the Cerrado’s native vegetation has been destroyed to make way for cattle, soy, and other agricultural commodities. In the southern Cerrado, scientists are now shifting their focus to restoring the native vegetation
- However, scientific knowledge on savanna restoration is scarce. So one collaborative network, Restaura Cerrado, is bringing together scientists, seed collectors, and the public to advance practical knowledge about restoration. The group’s goal is to achieve the means for ongoing effective Cerrado restoration.
- Restaura Cerrado is a collaboration between ICMBio, the University of Brasília, the Cerrado Seeds Network, and Embrapa (the Brazilian Agriculture and Animal Husbandry Research Enterprise); together they hope to use restoration to bring sustainable development to the savanna region.
[Photos] Tiny frog, venomous viper among 20 new species described in Bolivia
- An expedition into the cloud forests of the Bolivian Andes has uncovered 20 species new to science including a frog smaller than a coin, a new venomous pit viper, four butterflies, and four orchid species.
- Along with the newly described species, the research team also “rediscovered” four species believed to be extinct, including the devil-eyed frog not seen for 20 years.
- Overall, the expedition in the Zongo Valley near La Paz, Bolivia, uncovered rich diversity and endemism and recorded more than 1,200 plants, 247 insects, 10 amphibians, 10 reptiles, 161 birds, nine small terrestrial mammals, nine large mammals, and 12 species of bats.
- The Zongo Valley contributes drinking water and hydroelectric energy for the cities of La Paz and El Alto and is known to provide important ecosystem services. The report calls for urgent measures for formal conservation of this largely intact ecosystem.
Is Brazil’s biodiverse savanna getting the attention it deserves, finally?
- On this episode of the Mongabay Newscast we look at how the largest and most biodiverse tropical savanna on Earth, Brazil's Cerrado, may finally be getting the conservation attention it needs.
- We're joined by Mariana Siqueira, a landscape architect who's helping to find and propagate the Cerrado’s natural plant life, and is collaborating with ecologists researching the best way to restore the savanna habitat.
- Also appearing on the show is Arnaud Desbiez, founder and president of Brazilian NGO ICAS, who describes the Cerrado as an important part of the Brazilian range for the giant armadillo, a species whose conservation could play an important role in protecting what’s left of the Cerrado’s vast biodiversity.
Podcast: Lemur love and award-winning plant passion in Madagascar
- We’ve got recordings of indri lemurs and the architect of 11 new protected areas that aim to protect Madagascar’s rich biodiversity of plant life on this episode of the Mongabay Newscast.
- We’re joined by Jeannie Raharimampionana, a Malagasy botanist who has identified 80 priority areas for conservation of plant life in her country and has already turned 11 of those areas into officially decreed protected areas.
- We’re also joined by Valeria Torti, who uses bioacoustics to improve conservation of critically endangered indri lemurs in Madagascar’s Maromizaha forest. She plays for us a number of recordings of the primates’ songs.
Amazon botanist Sir Ghillean Prance: ‘The environmental crisis is a moral one’
- Sir Ghillean Prance first visited the Amazon in 1963 as a budding botanist, going on to describe more than 200 plant species and becoming a leading expert on the rainforest’s flora.
- But his studies coincided with a period of massive deforestation, prompting him to turn his focus toward generating data that would help inform more sustainable practices.
- Devoutly religious, Prance says Christians have a duty of care for “the creation on which our future depends.”
- In this interview with Mongabay founder and CEO Rhett A. Butler, Prance calls the ongoing environmental crisis “a moral, religious and ethical one.”
On a Philippine mountain, researchers describe a ‘fire flower’ orchid species
- A new wild orchid species, Dendrochilum ignisiflorum, has been described in the Philippine province of Benguet in the northern Cordilleras mountain range.
- This fiery orange orchid belongs to a genus found in high-elevation forests in Southeast Asia, particularly in the Philippines, Borneo and Sumatra.
- The scientists who described it say the species is threatened by climate change, which could make its niche range uninhabitable.
- The mountain where it’s found is also an increasingly popular tourist spot, while the forests in the area around it are being cleared for agriculture.
When roads cross wilderness areas, plant pathogens can hitch a ride
- Statistical analysis of the spread of a fungal plant pathogen across a Finnish island demonstrates that roads serve as corridors for the transmission of disease in wild plants.
- According to the researchers, their data indicate that vehicles traveling along roads are directly involved in spreading diseases, not just that roadsides make good habitats for pathogens.
- The research is based on a detailed data set maintained in southern Finland’s Åland Islands, but experts say the findings could apply to other similar pathogens.
A Philippine tribe’s plant-based medical tradition gets its moment
- A newly published study highlights the importance of medicinal plants that thrive on the ancestral lands of the Manobo Indigenous group in the southern Philippines.
- The Manobos of the highland Agusan region have for generations depended on their vast compendium of ethnomedicinal plants to treat a wide range of ailments.
- The popularity of this folk medicine has spread beyond the members of the tribe, with many of the treatments showing similar properties to established Western medicines.
- Further documentation and study of these ethnomedicinal plants could help in the preservation and conservation of the Indigenous group’s lands, say the authors of the recent study.
World’s plants and fungi a frontier of discovery, if we can protect them: Report
- The “State of the World’s Plants and Fungi 2020” report, released this week, was born of the collaborative effort of 200 scientists from 42 different countries and delves into a global assessment of plants and fungi as food, fuel, medicine, tools for urban resilience, and more.
- In 2019 alone, 1,942 plants and 1,886 fungi were newly described by scientists, some closely related to known medicinal species and potentially new sources of medicine.
- More than 7,000 edible plants hold potential as future crops, according to the report, meeting the criteria of being nutritious, robust and historically used as food.
- Nearly 40% of plant species are estimated to be threatened with extinction.
Fires turn sage brush habitat in Washington into a scorched ‘oblivion’
- Wildfires in Washington state have burned hundreds of thousands of acres, including an important mating habitat for sage grouse.
- More than half of the fewer than 1,000 birds in the state may have been lost in the fires, according to leading grouse expert Michael Schroeder.
- Prospects for the species’ recovery here look grim, given that what little habitat they had was surrounded by fields and towns, leaving them no room for refuge.
Missing mangroves are root of contention over Philippine airport project
- Work on a new international airport project in Bulacan, just north of Manila, has already resulted in the decimation of more than 600 mangrove trees in the Manila Bay area, residents say.
- Bulacan’s coast is a key mangrove forest and important bird and biodiversity area, and one of several sites along the bay that’s facing threats due to land reclamation projects.
- The Bulacan “aerotropolis,” a 2,500-hectare (6,200-acre) airport complex, is part of President Rodrigo Duterte’s revised “Build, Build, Build” infrastructure program and has been awarded to San Miguel Corporation, the Philippines’ biggest company by revenue.
- The cutting of mangroves is prohibited under Philippine law, but no one has been held accountable for the hundreds of trees cut in Bulacan — a problem that residents and environmental groups say will intensify as construction of the airport returns to full force by October.
Latin America has twice the plant life of Africa, SE Asia
- Latin America has more than twice as many plant species as tropical Africa and Southeast Asia and accounts for about a third of global biological diversity, concludes a new study published today in the journal Science Advances.
- Using botanical databases, researchers led Missouri Botanical Garden President Emeritus Peter Raven by found Latin America has 118,308 known species of vascular plants, the Afrotropical region has 56,451, and Southeast Asia has about 50,000.
- Latin America and the Afrotropical region are roughly equivalent in size, meaning that the Americas south of the Mexico-U.S. border have about twice the richness of species on a per-unit basis. But Southeast Asia, which is only a quarter the size of the other two regions, takes the biodiversity crown in terms of the density of species.
- The authors say that their research will be helpful in prioritizing conservation efforts, but that future data collection will be increasingly challenged by rapid habitat loss.
Lockdown should have cleared up Jakarta’s air. Coal plants kept it dirty
- Cities around the world have seen an improvement in air quality as a result of lockdowns and restrictions imposed in response to the COVID-19 pandemic, but Jakarta has been a notable exception.
- A new study shows that persistently high levels of PM2.5 air pollutant in the Indonesian capital come from coal-fired power plants within 100 kilometers (60 miles) of the city.
- Indonesia is set to build more coal-fired power plants in the vicinity of Jakarta in the coming years while maintaining emissions standards that are much laxer than regional or global standards.
- Air pollution has a significant impact on public health and the economy, with studies linking it to higher rates of COVID-19 infection.
Study revealing New Guinea’s plant life ‘first step’ toward protection
- A recent study in the journal Nature found that New Guinea has more plant species than any other island on Earth.
- The island has more than 13,000 species of plants, more than two-thirds of which live only in New Guinea.
- The island’s forests are relatively intact, and researchers say the list of species is a step toward protecting them from the looming threats of large-scale agriculture, logging and road building.
Illegal plant trade, tourism threaten new Philippine flowering herbs
- Scientists have described a new ornamental plant species in the biodiverse region of Palawan, a province in the western Philippines.
- The new species, Begonia cabanillasii, is the 25th begonia species found on the island and the 133rd recorded in the Philippines.
- Begonias are flowering perennial herbs popular in the ornamental plant trade. The new species grows in a shady and rocky undergrowth habitat in Palawan and is assessed to be critically endangered.
- The illegal plant trade and tourism, a driver of deforestation in the province, pose the biggest threat to this new plant species and other Palawan-endemic flora, researchers say.
Climate change could put tropical plant germination at risk: Study
- Under a worst-case climate change scenario, more than 20% of plant species in the tropics may experience temperatures too high for their seeds to germinate by 2070, according to an analysis of seed germination data compiled by the UK’s Royal Botanic Gardens Kew.
- Under that same worst-case scenario, over half of tropical species may see reduced rates of germination by 2070 as well, the study reports, while many temperate species at high latitudes will move closer to their optimum temperature and may experience increased germination success as a result.
- The analysis shows that 26% of tropical species and 10% of temperate species are already experiencing temperatures above their optimum. Some plants are found living at sites where temperatures are already above their maximum, suggesting that their lineage in that location may be effectively extinct.
- Plants that find themselves outside of optimum or tolerable temperature ranges may be able to migrate to higher latitudes or altitudes, and existing diversity can offer a reservoir of genetic variation for species to adapt, but physiological limits and long generation times may mean even diverse species struggle.
New Guinea has the most plant species of any island
- New Guinea is the planet’s most speciose island when it comes to plants, reports a comprehensive assessment of vascular plant species published in the journal Nature.
- The research concludes New Guinea has 13,634 species of plants from 1742 genera and 264 families. That gives New Guinea, the world’s second largest island, the highest plant diversity of any island on Earth, surpassing Madagascar (11,832 species), Borneo (11,165 species), and Sumatra (8,391 species).
- New Guinea’s flora is also highly unique. The study finds that more than two-thirds of its plants are endemic, meaning they are only found on the island.
- But time may be running short for New Guinea’s biodiversity, since 2002 the island lost 1.15 million hectares of primary forest and nearly 2 million hectares of total tree cover. New Guinea’s high degree of endemism makes its flora particularly vulnerable.
Amazonia’s people domesticated crops on ‘forest islands’ 10,000 years ago: Study
- Early Amazon human inhabitants domesticated and grew crops more than 10,000 years ago, making the region one of the world’s earliest centers of plant domestication for food, a study has found.
- These early people left behind thousands of artificial raised forest islands in what is now the Llanos de Moxos savanna in northern Bolivia.
- Researchers tracked glass-like microfossils to reveal evidence that these early farmers grew squash, corn and cassava.
- The new research helps dispel a persistent myth that the Amazon long existed as a sort of wilderness paradise, largely untouched by human influences. Instead, it is now thought that humans have been profoundly altering the landscape of Amazonia for thousands of years, with lasting consequences for species conservation and habitats.
In Sri Lanka, a South American flower usurps a tree sacred to Buddhists and Hindus
- The cannonball tree, with its red, pink and yellow flowers with a soft fragrance, is native to South America and gets its name from its large, round fruit.
- The British introduced the plant to Sri Lanka, India and other parts of Asia in the 19 century, and its flower has since been imbued with religious significance by many Hindus and Buddhists, who believe it comes from the sacred sal tree.
- But the real sal tree is the native Shorea robusta, mentioned in the Buddhist and Hindu tales that predate the arrival of the cannonball tree by more than 2,000 years.
- The cannonball tree is increasingly misidentified as the sal tree, including in school textbooks and official ceremonies.
‘In the plantations there is hunger and loneliness’: The cultural dimensions of food insecurity in Papua (commentary)
- Sophie Chao is an anthropologist who has spent years studying the Marind people of southern Papua.
- As palm oil companies take over their land, the Marind, she writes, are struggling to feed themselves.
- Photographs in this article feature Marind, Mandobo and Auyu tribespeople in southern Papua and were taken by Albertus Vembrianto.
38 endangered Brazilian tree species legally traded, poorly tracked: Study
- A recent study found that 38 tree species officially listed by Brazil as threatened with extinction were traded between 2012 and 2016. Though prohibited from being harvested, the timber of the threatened trees was traded within Brazil and exported.
- Of the 38 threatened tree species traded, 17 were classified as Vulnerable, 18 as Endangered, and three as Critically Endangered.
- To end this exploitation, scientists urge that the timber no longer be tracked only at the genus level, but at the species level. They also recommend better coordination between IBAMA, Brazil’s environmental agency, which designates threat levels, and the Institute of Geography and Statistics (IBGE) which tracks wood products.
- Another systemic problem: of the 38 threatened species, some are not included on the IUCN Red List or on the CITES species checklist. The study urged IUCN and CITES update their lists to include all 38 of the species found to be threatened by IBAMA.
From a Philippine conflict hotspot, a new insect-eating plant emerges
- Filipino scientists have discovered a new species of insect-eating pitcher plant in a mountain range in the country’s southern Mindanao region.
- The range is a key biodiverse area but has not been granted any form of environmental protection, and is prone to armed conflicts, criminal activity, and tribal wars.
- The scientists risked threats to explore the unprotected remote area, but say they are determined to catalog as much of the biodiversity as they can before it is destroyed by logging and land conversion activities.
- Identifying new species could help preserve the ecology of this area that is crucial to the existence of indigenous ethnolinguistic groups, researchers say.
They survived centuries of elephant onslaught. Now climate change is killing these iconic baobabs
- A years-long drought across Southern Africa, exacerbated by climate change and over-use of water by industry, has driven elephants into South Africa’s Mapungubwe National Park.
- Here, they tear into the park’s centuries-old babobab trees to get at the moist interior.
- While the babobabs have evolved to tolerate occasional elephant damage and benefit from elephants eating their fruit and dispersing the seeds, the damage done during times of drought is extensive and often deadly for the trees.
- The elephants, for their part, no longer have room to maneuver: they’re trapped between climate change, habitat destruction and poaching.
Land scarcity and disease threaten a multifaceted indigenous crop in Ethiopia
- Although varieties of the plant are found in many sub-Saharan countries, only in Ethiopia has it been domesticated.
- Land scarcity means farmers are turning to growing more lucrative cash crops, such as the stimulant khat or maize, with the number of enset farms declining in recent decades.
- The plant is also threatened by blight, leading researchers to develop a genetically modified variety that’s now being tested — amid controversy — for disease resistance.
As habitat degradation threatens Amazon species, one region offers hope
- Two recent studies looked into the impact of human disturbance on ecological diversity in Amazonia habitats. Another study in the Rupununi region of Guyana found how important maintaining connectivity is to maintaining ecosystem health.
- The first study investigated how forest fragmentation impacts mixed-species flocks of birds. The research found evidence that forest habitat fragmentation in the Amazon has caused mixed-species bird flocks to severely diminish and even disappear.
- A second study evaluated the impact of logging and fire on seed dispersal in tropical forest plots in the eastern Brazilian Amazon. The research team found that Amazon forests which have been heavily logged and burned are populated primarily by tree species with smaller seeds, and smaller fruits.
- The remote Rupununi region provides water connectivity between the ancient Guyana Shield and the Amazon basin. A recent study there identified more than 450 fish species within the Rupununi region. The research illustrated the value of conserving connectivity between diverse habitats.
From a Sri Lankan rainforest, a new species of orchid blooms
- A rare new orchid species found in the UNESCO-declared heritage lowland rainforest Sinharaja has been named in honor of two pioneering forest ecologists, Nimal and Savithri Gunatilleke.
- The botanists who described Gastrodia gunatillekeorum discovered only three small populations within Sinharaja, comprising fewer than a hundred mature individuals and considered endangered.
- Any change in the habitat condition is likely to bring change in the fungus community, and by extension to the orchid populations that depend on these fungi for their nutrition, the researchers say.
In Sri Lanka, beguiling bloom of cat’s claw vine conceals potential trouble (commentary)
- A beautiful creeper known as the cat’s claw vine has become something of a springtime attraction in Sri Lanka, but its explosive growth could turn it into an invasive species.
- The exotic species, introduced as an ornamental plant from the New World, can grow up to 30 meters (98 feet), enabling it to reach even the canopies of tall trees, posing huge problems to host trees and smothering smaller plants.
- Other countries around the world, including the U.S., have categorized it as an invasive alien species — something Sri Lanka may have to consider once the plant begins to pose a threat to the native vegetation.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Impending Amazon tipping point puts biome and world at risk, scientists warn
- Climate models coupled with real world biome changes are causing prominent scientists to forecast that, unless action is taken immediately, 50 to 70% of the Amazon will be transformed from rainforest into savanna in less than 50 years.
- That ecological disaster would trigger a vast release of carbon stored in vegetation, likely leading to a regional and planetary climate catastrophe. The Amazon rainforest-to-savanna tipping point is being triggered by rapidly escalating deforestation, regional and global climate change, and increasing Amazon wildfires — all of which are making the region dryer.
- While models produced the first evidence of the tipping point, events on the ground are now adding to grave concern. The Amazon has grown hotter and dryer in recent decades, and rainforest that was once fireproof now readily burns. Plant species adapted to a wet climate are dying, as drought-resistant species flourish. Deforestation is escalating rapidly.
- Scientists say the tipping point could be reversed with strong environmental policies. However, Brazilian President Jair Bolsonaro is moving in the opposite direction, with plans to develop the Amazon, including the opening of indigenous reserves to industrial mining and agribusiness, and the building of roads, dams and other infrastructure.
Mass tree planting along India’s Cauvery River has scientists worried
- A plan to plant 2.42 billion trees by the Isha Foundation along the Cauvery River has attracted the chagrin of some scientists.
- While scientists say the project is well-meaning, they don’t believe it will cure the Cauvery River’s ills as promised.
- The Isha Foundation has yet to announce a number of details of the project, including what tree species will be planted.
- India’s rivers are suffering from numerous issues, but researchers contend mass tree planting is too simplistic to fix them all.
Cost-effective conservation: Study identifies key ‘umbrella’ species
- A new study has found that incorporating threats, actions and costs into the selection of priority species for conservation can markedly increase the efficiency of these efforts.
- The researchers created a new list of “umbrella” species for Australia, incorporating these factors.
- They found that the new list of umbrella species would lend protection to 46% of Australia’s threatened species — a sevenfold increase over the current list.
Philippine fern efficiently absorbs arsenic, copper from toxic mining soil
- Scientists conducted a study on a fern found to grow only in two copper mining sites in the Philippines, called Pteris melanocaulon.
- This local fern can absorb high concentrations of both copper and arsenic — a unique ability that has not been recorded so far among fern species called metallophytes that are known to absorb heavy metals.
- The fern’s ability to withstand and absorb high levels of both copper and arsenic without showing symptoms of toxicity makes it a possible indigenous and natural solution for rehabilitating mining sites at the end of mining operations, the researchers say.
Rare plant species are especially vulnerable to climate change, and rarity is more common than previously understood
- Researchers from around the world spent 10 years compiling a database that now includes 20 million observational records of plant species occurrence, which they say is the largest dataset on botanical biodiversity ever created.
- They found that there are about 435,000 unique land plant species on planet Earth, and that a large fraction of them, 36.5% or some 158,535 species, can be considered “exceedingly rare,” meaning that they have only been observed and recorded anywhere in the world up to five times. In fact, 28.3% of the world’s plants, or 123,149 species, have been observed just three times or less, per the study.
- The research team found that rare species are clustered in a handful of rarity hotspots, and that global warming and the impacts of human land use are already disproportionately impacting the regions that harbor most of these rare plant species.
Photos: Top 15 new species of 2019
- In 2019, Mongabay covered several announcements of new-to-science species.
- The “discovery” of a new-to-science species is always an awe-inspiring bit of news; the outcome of dogged perseverance, months or years of field surveys, and long periods of sifting through hundreds of museum records.
- In no particular order, we present our 15 top picks.
Bringing back extinct plants to life: Q&A with ‘plant messiah’ Carlos Magdalena
- Carlos Magdalena, a botanical horticulturalist at the Royal Botanic Gardens, Kew, U.K., who’s been labeled the “plant messiah” by the media, has figured out how to get some of the world’s rarest plant species to grow.
- Magdalena travels around the world collecting seeds and cuttings of extremely rare plant species, then brings them back to the Royal Botanic Gardens, where, together with his colleagues, he sets about trying to propagate them.
- But the clock is ticking, he tells Mongabay. Tropical forests with high biodiversity are being razed around the world and plants are going extinct by the hour.
- Mongabay chatted with Magdalena over the phone about what it takes to save rare plants and what drives him.
Amazonian tree with human-sized leaves finally gets ID’d as new species
- More than 35 years after it was first seen, researchers have described Coccoloba gigantifolia, a tree species from the Brazilian Amazon with gigantic leaves that can reach 2.5 meters (8 feet) in length.
- Although C. gigantifolia has been known to the public and the scientific community for a long time, describing it formally and giving it an official name was essential to be able to assess its conservation status and design conservation strategies to protect it, the researchers say.
- The species is rare and likely has disjointed populations occurring in a rapidly changing landscape, and the researchers recommended listing it as endangered on the IUCN Red List.
New assessment method finds close to one-third of tropical Africa’s plants are potentially facing extinction
- A new study, published today in the journal Science Advances, uses a novel methodology based on key components of the IUCN Red List’s assessment process to discern the potential conservation status of tropical flora at the continental scale.
- Researchers tested the new assessment method using the recently developed RAINBIO database, which consists of over 600,000 geo-referenced occurrence records of more than 20,000 vascular plant species in tropical Africa.
- The research team found that 17.3 percent of the 22,036 vascular plant species included in the study are likely threatened, while 14.4 percent are potentially threatened. That means that nearly one-third — 31.7 percent — of tropical Africa’s vascular plant species might be at risk of going extinct.
Lawsuit against Indonesian coal plant reveals permit irregularities
- Residents opposed to a newly built coal-fired power plant in Sumatra have alleged a list of irregularities that they say should have disqualified the developer from obtaining an environmental permit.
- A key point is that the project violates provincial and municipal zoning regulations; the latter allows for a plant to be built, but at a different location, while the former makes no accommodation for a coal plant.
- The project site, on Sepang Bay along the southwest coast of Sumatra, has also been identified as an area prone to earthquakes and tsunamis, while the developer hasn’t formalized plans for such contingencies.
- The National Ombudsman has weighed in with findings of maladministration by the provincial government in issuing the environmental permit, but adds that the zoning regulations should be adapted to accommodate for the plant now that it’s been built and is undergoing a trial run.
Biodiversity ‘not just an environmental issue’: Q&A with IPBES ex-chair Robert Watson
- The World Bank and IMF meetings from Oct. 14-20 will include discussions on protecting biodiversity and the importance of investing in nature.
- A recent U.N. report found that more than 1 million species of plants and animals face extinction.
- In a conversation with Mongabay, Robert Watson, who chaired the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services that produced the report, discusses the economic value of biodiversity.
Study tracks first incursion of poachers into ‘pristine’ African forest
- Researchers logged the first evidence of elephant poaching in a remote, pristine section of Nouabalé-Ndoki National Park in the northern Republic of Congo.
- The study, published in the journal Frontiers in Forests and Global Change, also revealed unique behavior changes between gorillas and chimpanzees as a result of selective logging.
- The research highlights the need to incorporate the results of biodiversity surveys into plotting out the locations of areas set aside for conservation.
Wilderness cuts the risk of extinction for species in half
- Wilderness areas buffer species against the risk of extinction, reducing it by more than half, a new study shows.
- Places with lots of unique species and wilderness with the last remaining sections of good habitat for certain species had a more pronounced impact on extinction risk.
- The authors contend that safeguarding the last wild places should be a conservation priority alongside the protection and restoration of heavily impacted “hotspots.”
Climate change threatens some island conifers with extinction
- A quarter of 55 conifer species native to islands are likely to go extinct by 2070 due to climate change, researchers from Brown University write in a new study.
- The researchers looked at where these species are living and thriving outside their native climatic ranges, to study their climatic tolerance in a more comprehensive way.
- Island conifers are keystone species, playing a vital part in maintaining the ecosystem and ensuring the survival of other species that depend on them.
- If the conifers in an ecosystem go extinct, the entire nature and composition of species found in that place could change dramatically.
‘Radically changing’ a rare Mauritian plant’s story: Q&A with ecologist Prishnee Bissessur
- Roussea simplex, a unique plant that grows only on the mountains of Mauritius, is the only species in its genus, with just 250-odd individuals remaining in the wild.
- Prishnee Bissessur, a graduate student at the University of Mauritius who has been studying the plant since 2015, has “radically changed what was known of the plant’s ecology so far,” according to one ecologist.
- Mongabay spoke with Bissessur to learn about her work on Roussea simplex, what makes the plant so fascinating, and the challenges of studying it.
Wild orchid trade in China is huge, overlooked and ‘devastating,’ study finds
- In just one year of survey, researchers recorded more than 400 species of wild-caught orchids, involving 1.2 million individual plants worth potentially more than $14.6 million, being traded at markets in southern China.
- At least some of the trade is illegal and in breach of CITES regulations, the study found.
- Traders frequently sell non-native species of orchids. Moreover, native species that either have very small populations or have probably gone extinct in China also appear in the markets, suggesting they are likely being sourced from neighboring countries.
Mysterious plants that thrive in darkness, steal food: Q&A with botanist Kenji Suetsugu
- On Japan’s forest floors, there are plants that stay hidden and have given up on photosynthesis. These mycoheterotrophic plants are instead parasitic, drawing nutrition from the network of fungi running under the forest floor.
- For the past 10 years, Kenji Suetsugu, a botanist and associate professor at Japan’s Kobe University, has been on a mission to identify and document mycoheterotrophic plants across the country’s. His surveys have uncovered 10 previously undescribed species of these elusive plants.
- In a brief chat, Mongabay spoke with Suetsugu about the strange world of mycoheterotrophic plants, why it fascinates him, and why it’s an important indicator of ecosystem health.
New orchid species from Japan lives on dark forest floor, never blooms
- Researcher Kenji Suetsugu of Kobe University has found flowering plants of a new species of orchid on Japan’s Amami-Oshima and Tokunoshima islands, now named Gastrodia amamiana.
- G. amamiana belongs to a group of mycoheterotrophic orchids that live on dark forest floors, do not use photosynthesis to get their nutrients, and steal nutrition from fungi instead. G. amamiana’s flowers likely never open up or bloom.
- Researchers have already found evidence of tree thinning close to where G. amamiana was discovered, and they worry that logging could dry the soil and consequently the fungi that the orchid depends on.
New toolkit identifies multiple species from environmental DNA
- Researchers have developed a DNA analysis toolkit designed to speed the identification of the multiple species in a biological community by analyzing environmental DNA from a sample of water or soil.
- To confirm the presence of a species at a site, the tool compares its genetic barcode (short DNA sequence) to barcodes of known species in one of several reference databases.
- The toolkit’s advantage is its ability to quickly process many barcode sequences, at multiple analysis locations on the gene, that enable it to identify the species of the DNA sequences of many organisms at the same time.
Venezuelan crisis: Caring for priceless botanical treasures in a failed state
- Venezuela’s Botanical Garden of Caracas was declared a UNESCO World Heritage Site in 2000. Its 70-hectare (173-acre) garden, National Herbarium and Henri Pittier Library are considered a national, and international treasure, and a vital repository of Latin American and global natural history utilized frequently by researchers.
- But a devastating drought that started two years ago, plus massive thefts of equipment (ranging from air conditioners to computers, plumbing and even electrical wiring), plus a failed electrical and public water supply, have all combined to threaten the Garden’s priceless collections.
- The annual botanical garden budget has been slashed to a mere $500 per year, which has forced staff to rely on innovative conservation solutions which include crowd funding to pay for rainwater cisterns, as well as volunteer programs in which participants contribute not only labor, but irrigation water they bring from home.
- As Venezuela’s government grows increasingly corrupt and incompetent, and as the national economy spirals out of control with hyperinflation topping 1.7 million percent in 2018, the botanical garden’s curators have no ready answers as to how to go about preserving the rare plants they tend on into the future.
Two ferns presumed extinct found on remote Australian mountaintops
- Researchers have rediscovered two species of ferns on the mountaintops of Queensland, Australia, that were last seen more than 50 years ago and presumed extinct.
- The ferns, Hymenophyllum whitei and Oreogrammitis leonardii, were found on Thornton Peak and Mount Finnigan respectively during an expedition in August 2017.
- Researchers recommend listing both species as endangered in Queensland because they occur over a very limited area.
Building a global inventory of plants: Q&A with botanist Patrick Weigelt
- The Global Inventory of Floras and Traits, or GIFT 1.0, is the first database of its kind, bringing together thousands of published and unpublished plant
species checklists and inventories from around the world.
- It holds more than 3,800 species lists for nearly 2,900 regions around the world, covering about 79 percent of the global land surface and 80 percent (more than 315,000 species) of all plant species known to science, the researchers who created the database say.
- Mongabay spoke with Patrick Weigelt, co-developer of GIFT, about what went into creating the database, and what it can be used for.
Making room for wild foods in forest conservation
- The first-ever FAO report on the importance of biodiversity for food and agriculture warns that the abundance of our food supply is diminishing — with worrisome consequences for global food security.
- The report also looks at the decline in wild foods, an underreported but essential component of food security, especially for forest dependent communities.
- While wild foods make up less than 1 percent of global caloric intake, they provide essential micronutrients to hundreds of millions of people.
- Acknowledging the role that wild food plays for forest-dependent communities, and the right of access to those foods, could be an important contribution to the debate around forest conservation.
From over 100,000 species assessments in IUCN update, zero improvements
- The latest IUCN Red List update, which includes assessments of 105,732 species, lists more than 28,000 species as threatened with extinction.
- The declines of many of these species can be attributed to human overexploitation, according to the IUCN. The red-capped mangabey (Cercocebus torquatus), for example, has moved from vulnerable to endangered in 2019, largely because of threats from illegal hunting for bushmeat and conversion of much of the monkey’s Atlantic coast forest habitat in West Africa to agriculture.
- More than 5,000 trees from 180 countries, and 500 deep-sea bony fish species like the bioluminescent lanternfishes, were also added to the Red List this year.
- No species was assessed as having genuinely improved in status enough to earn it a place in a lower threat category, according to the IUCN.
Newly described tree species from Tanzania is likely endangered
- Researchers have described a new species of tree from the Usambara mountains of northeastern Tanzania.
- The tree, which grows up to 20 meters (66 feet) in height, has been named Mischogyne iddii after Iddi Rajabu, a resident botanist at the Amani Nature Reserve, where some individuals of the tree can be found.
- The newly described species is known from only two locations in the Usambara mountains, and the researchers estimate that fewer than 50 individuals remain, suggesting a threat category of endangered on the IUCN Red List for the species.
More than 10,000 animals and plants seized in massive global operation
- A 26-day worldwide effort in June termed Operation Thunderball, coordinated by Interpol and the World Customs Organization (WCO), led to seizures of thousands of protected animals and plants.
- Confiscated items included more than 2,600 plants, nearly 10,000 live turtles and tortoises, more than 4,300 birds, 23 live primates, 30 big cats, 440 pieces of elephant tusks, nearly 10,000 marine wildlife animals and their products, and 74 truckloads of timber.
- Based on intelligence gathered before the operation was launched, the authorities identified wildlife trafficking routes and smuggling hotspots, which then led to seizures and almost 600 people being identified as suspects.
Are plants conscious? The debate rages on
- An opinion piece in the journal Trends in Plant Science emphatically argues that plants are not conscious.
- The article questions the soundness of widely covered studies that mimosa plants (Mimosa pudica) and peas (Pisum sativum) display learning behaviors that amount to having a consciousness.
- Plants do not have a brain or anything resembling it, the authors point out, and to possess consciousness a structurally complex brain is required.
- Monica Gagliano, who has reported learning behaviors in plants, rejects this view saying that the criteria used to determine animal consciousness cannot be uncritically extrapolated to plants, and that the opinion piece fails to cite sound evidence.
Nearly 600 plant species have gone extinct in last 250 years
- At least 571 species of seed-bearing plants have gone extinct around the world in the last two and a half centuries.
- This number is nearly four times higher than the previous known estimate and more than twice the number of birds, mammals and amphibians that are known to have gone extinct, researchers say.
- The study estimates that plants are now becoming extinct nearly 500 times faster than the background extinction rate for plants.
- The geographical pattern of modern plant extinctions resembles that for animals: most plant extinctions occur on islands, in the tropics, and in areas with a Mediterranean climate that are rich in biodiversity.
‘You don’t find orchids; they find you’: Q&A with botanist Edicson Parra
- Edicson Parra has not only discovered more than 20 new species of orchids in his home country of Colombia, but has also used his expertise in orchid diversity to help halt development, road and mining projects that would have otherwise threatened their forest habitats.
- But studying orchids can be a dangerous challenge in Colombia, due to drug traffickers and threats to environmentalists in the country.
- Parra says orchids could be “one of the most sensitive of all Earth’s taxa.” Orchids are particularly vulnerable and fragile to deforestation, including edge effects, making protecting large tracts of forests key to their survival.
Study reveals a fragile web of knowledge linking plants to people
- To understand how indigenous knowledge is structured, researchers chose to focus on communities’ use of palm plants, which are used across the world for a range of economically important needs — from medicine to rituals, roofing to flooring, hair products to handy tote bags.
- The primary goal of the research was not to document the uses of the palms, but to study how knowledge is held in communities and how it might change.
- The team concluded that cultural heritage is just as important as the plants themselves in our realization of nature’s services.
In Ethiopia’s Addis Ababa, Gullele Botanical Garden captivates city dwellers
- Gullele Botanic Garden (GBG) is the first of its kind located in Addis Ababa, Ethiopia.
- Officially inaugurated and opened to the public in January 2019, it has become increasingly popular among the city’s residents and educators.
- On a smaller scale, similar initiatives such as Shashemene Botanical Garden are being undertaken elsewhere in the country.
Earth’s hidden tree-microbe network mapped for the first time ever
- For the first time ever, researchers have mapped the underground network of microbes connecting forest trees around the world using an enormous data set of more than 1.1 million forest plots.
- Mapping the forest microbe network required global collaboration and high computing capabilities.
- The new maps confirm patterns that have been long suspected. For example, arbuscular mycorrhizal fungi dominate forests in the warmer tropics while ectomycorrhizal fungi are more widespread in colder boreal and temperate forests.
- The predicted maps are, however, limited by the geographic coverage and sampling density of trees across the world. While the coverage is good in developed countries, it is relatively poor in developing countries like India, China and countries in the tropical region, the researchers say.
