Thermal drones detect rare tree kangaroos in Australia
Tree kangaroos, which live high up in the tall rainforest trees of New Guinea and Australia, are usually very hard to spot from the ground. But thermal drones, which detect animals from their body heat, can help find these animals quickly, a new study has found. In November 2024, Emmeline Norris, a Ph.D. student at […]
Researchers eye marsupial recovery with first IVF kangaroo embryo
Researchers in Australia have successfully created the first kangaroo embryo using in vitro fertilization, or IVF, according to a new study. The team from the University of Queensland used IVF to produce an embryo of the eastern gray kangaroo (Macropus giganteus). Researchers say they hope to use the information they’ve gathered to help with the […]
Australian bushfires leave wildlife facing increased predator risk, decades of recovery
Simultaneous wildfires since December 2024 have left Grampians, Little Desert and the Great Otway National Parks in Australia devastated. Scientists say it will take decades for plants and wildlife to recover. Michael Clarke, emeritus professor of zoology at La Trobe University in Melbourne, told Mongabay by email the area burnt in Little Desert alone is […]
Japan sees record snowfall as Australia braces for cyclone Zelia
Japan: Record-breaking snowfall wreaked havoc in northern Japan last week, leaving at least three people dead and 54 injured as of Feb. 10, according to Japan’s Fire and Disaster Management Agency. Among the worst hit regions were Hokkaido, the country’s northernmost island, and the Japan Sea coast. The thick snow halted transportation in many areas […]
Australia reeling from floods in the north, bushfires in the south
Northeastern Australia, particularly the state of Queensland, has faced record-breaking rainfall of up to 2 meters, or 6.5 feet, since Feb. 1, reportedly leaving at least two people dead. Queensland Premier David Crisafulli called the damage “quite frankly incredible,” with the state experiencing nonstop rains, heavy flooding and power outages, BBC reported. He also called […]
Historic Arctic freeze for US South and record rain in Western Australia
The southern states of the U.S. are facing a winter storm this week that will bring heavy snow and ice to a region that rarely experiences such conditions. More than 220 million people are expected to be affected from Texas to South Carolina. Several states, including Louisiana, Georgia, Alabama, Florida and Mississippi, have each already […]
A venomous Australian spider turns out to be 3 species, not 1
The Sydney funnel-web spider, a highly venomous arachnid found crawling in and around Australia’s most populous city, was long thought to be a single species. But it’s actually three different species, a new study has found. One of these, called “Big Boy” for its unusually large size, is new to science. “You would think we […]
Turn problems into solutions for culture and agriculture across Australia and the Americas, Anthony James says
Anthony James, host of The RegenNarration Podcast, joins Mongabay’s podcast to share news and views on community resilience and land regeneration in both the Americas and Australia. James recounts how some creatures seen as invasive pests in Australia, like donkeys, are actually now being managed in a way that benefits the land, in places like […]
South Australia bans fishing of many sharks and rays in its waters
The state of South Australia has banned fishing of several endangered or critically endangered sharks and rays in its waters. In a media release dated Dec. 11, the state government said the new rules prohibit both recreational and commercial fishing of critically endangered species such as the whitefin swellshark (Cephaloscyllium albipinnum), oceanic whitetip shark (Carcharhinus […]
Researchers propose a ‘circular economy’ solution to housing affordability against climate change
A global housing affordability crisis is underway, so when the Center for Demographics and Policy at Chapman University in the U.S. released a report this year highlighting the “disastrous” state of housing affordability for 94 markets — where median home prices far exceed median wages by many times, making housing much more expensive for the […]
Citizen scientists can boost IUCN species assessments, but need better guidance from ecologists
- More than 100,000 Australian citizen scientists are contributing crucial biodiversity data about species at risk, helping improve conservation efforts in ways that can enhance IUCN Red List decisions.
- Citizen science projects like Fungimap and FrogID showcase how such observations have influenced threat assessments and conservation outcomes.
- Researchers stress the need for clear goals, standardized protocols, and expert oversight to maximize the impact of citizen science.
Mining drove 1.4m hectares of forest loss in last 2 decades: Report
Global mining activity is increasingly destroying forests, including protected areas, according to a recent analysis. Between 2001 and 2020, nearly 1.4 million hectares (3.5 million acres) of tree cover, an area a third the size of Denmark, was lost from mining-related activity, the analysis from the World Resources Institute (WRI) found. The associated greenhouse gas […]
Bird-watching with drones? Might want to watch your distance, study says
As researchers and wildlife enthusiasts increasingly use drones to watch birds, a new study has come out with guidelines for best drone operating practices that minimize disturbance. “This study represents an important first step in understanding wildlife responses to drones and promoting ethical considerations in the use of new technologies in wildlife monitoring,” Meredith Palmer, […]
Researchers track koalas using innovative airborne DNA detection tool
What’s new: Researchers have successfully detected the presence of koalas and other threatened wildlife species using new tools that allow easy collection of airborne environmental DNA, according to a recent study. What the study says: It’s often difficult, time-consuming and expensive to collect data and observe threatened wildlife like koalas (Phascolarctos cinereus), small marsupials that […]
Australia’s Global ‘Nature Positive’ Summit features Indigenous voices, but little government action
SYDNEY – Just prior to the COP16 biodiversity summit in Colombia, the Australian Government hosted the world’s first Global ‘Nature Positive’ Summit. ‘Nature positive’ means “an improvement in the diversity, abundance, resilience, and integrity of ecosystems from a baseline” according to Australia’s Environmental Protection and Biodiversity Conservation Act (EPBC) and is a key part of […]
Sea lions with video cameras help scientists map ocean floor
For the first time ever, scientists have had help from sea lions in mapping the ocean floor. And the marine mammals have done their job well, capturing six different marine habitats, including algal meadows and reefs, that make up South Australia’s seabed, researchers report in a recently published study. For much of the planet’s ocean, […]
Recently hatched baby skate offers hope for endangered Tasman species
A captive-breeding program for the Maugean skate, one of the rarest marine fish in the world, has given researchers hope: a baby Maugean skate has hatched from an egg laid in captivity, for the first time ever. The Maugean skate (Dipturus maugeanus; formerly Zearaja maugeana) is today known to occur only in Macquarie Harbour, an […]
Cloud brightening over oceans may stave off climate change, but with risk
- Marine cloud brightening (MCB), the spraying of sea salt aerosols or other fine particles into clouds to artificially brighten them and increase the sun’s reflectivity, is a proposed strategy to ward off the full effects of climate change.
- However, this solar radiation management (SRM) geoengineering technique is highly controversial, and experts say governance of MCB field experiments and deployment is needed now at the national and international levels.
- Ongoing efforts to include marine cloud brightening under an international anti-marine pollution treaty, the London Protocol, could be one effective route to setting standards for research and field experiments.
- But if MCB is deployed on a large scale, some experts say there is the potential for serious negative effects on the global climate system. These impacts could be especially severe if deployment is uncontrolled and lacks science-based governance.
Rare mutant blue-skinned frog spotted in Australia
In a remote part of Australia, researchers recently stumbled upon an unusual, blue-skinned tree frog. This individual is a rare genetic mutant of the magnificent tree frog, a large amphibian that’s normally green in color, researchers say. The magnificent tree frog (Litoria splendida), also called the splendid tree frog, is found only in the far […]
‘Masters of deception’ cuckoos evolving into new species
Many cuckoos like to outsource their parenting. These medium-sized birds lay their eggs in the nests of other bird species, tricking the unsuspecting hosts into raising their chicks. In some cuckoo species, the chicks grow alongside the host’s offspring. In others, the cuckoo chicks eject the hosts’ babies from the nests. This deception can be […]
Shaping the next generation of Indigenous rangers: Interview with Manni Edwards
- Aboriginal elders in the far north of Australia’s Queensland state are preparing the next generation of junior rangers to conserve endangered southern cassowaries, take care of their traditional land, safeguard their culture, and hold on to millennia of acquired knowledge.
- Along with declining southern cassowary numbers, traditional knowledge and values are diminishing in youth who put more attention on Western knowledge and technology.
- The young rangers not only spend time learning in classrooms; they also go out into the traditional country with elders who help shape their character and identity as caretakers of their people, land, Mother Earth and themselves.
- Ranger Manni Edwards says the way to effective conservation in his community, and in Australia, is by bringing together scientific and traditional ecological knowledge, which includes wisdom and values that forge a connection between people and nature.
Frog ‘saunas’ may help threatened frogs fight off deadly fungus
- Researchers have developed simple, sun-heated shelters that allow frogs to raise their body temperatures and fight off a deadly fungal disease called chytridiomycosis.
- The study focused on the green and golden bell frog in Australia, a threatened species, showing that frogs given access to these warm shelters cleared infections faster and developed resistance to future infections.
- This innovative approach could provide a valuable, low-cost tool for protecting various amphibian species threatened by the fungal disease, which has devastated amphibian populations worldwide.
- The research comes at a critical time, as a recent study found that two in five amphibian species are now threatened with extinction, with climate change becoming a primary threat.
Study: More than half of Australia’s clean energy mines lie on Indigenous land
- The global energy transition has increased demand for the minerals needed in the production of batteries, solar panels and other renewable energy technology.
- In a new study, researchers found that 57.8% of critical mineral projects in Australia lie within formally recognized Indigenous lands, or 79.2% if land subject to claims of native title that haven’t yet been determined are included.
- Historically, Australia’s First Nations haven’t received fair compensation or benefit sharing when investors have found resources in their territories, sources told Mongabay.
- The paper’s authors, Indigenous organizations and environmental campaigners say that critical mineral policies must consider the rights and interests of First Nations peoples throughout a project’s life cycle.
Indigenous people and NGO grow a wildlife corridor in the world’s oldest rainforest
- Environmental charity Climate Force is collaborating with the Eastern Kuku Yalanji people and rangers to create a wildlife corridor that runs between two UNESCO World Heritage Sites in Australia: the Daintree Rainforest and the Great Barrier Reef.
- Wildlife habitats in this region have become fragmented due to industrial agriculture, and a forested corridor is expected to help protect biodiversity by allowing animals to forage for food and connect different populations for mating and migration.
- The project aims to plant 360,000 trees over an area of 213 hectares (526 acres); so far, it has planted 25,000 trees of 180 species on the land and in the nursery, which can also feed a range of native wildlife.
- The project is ambitious and organizers say they’re hopeful about it, but challenges remain, including soil regeneration and ensuring the planted trees aren’t killed off by feral pigs or flooding.
Australian state fails on koala conservation while relying on faulty offset schemes, experts say
- Two experts join Mongabay’s podcast to discuss the decline in koala populations in the Australian state of New South Wales, and the government’s failure to protect them while allowing the clearing of koala habitats for development projects and using biodiversity offset schemes that don’t work.
- Despite promising to establish a Great Koala National Park in New South Wales, Premier Chris Minns has delayed gazetting it while allowing logging of native woodland within the borders of the proposed park, says guest Stephen Long of the Australia Institute.
- One reason for the delay, Minns claims, is the need to monetize the park via carbon credits, even though the land – and therefore the carbon – would be protected anyway, as it is part of a proposed national park.
- Researcher Yung En Chee from the University of Melbourne also joins the show to explain why biodiversity offset schemes to compensate for the damage housing developments pose to koala habitats do not work, are sometimes based on outdated data, and don’t even come close to satisfying ‘no net loss’ of biodiversity in the state. “I'm not sure how long this failure has to persist before we decide that we really ought to change course,” says Chee.
Indonesian palm oil, Brazilian beef top contributors to U.S. deforestation exposure
- A new report reveals that the United States imported palm oil, cattle products, soybeans, cocoa, rubber, coffee and corn linked to an area of tropical deforestation the size of Los Angeles between October 2021 and November 2023.
- Palm oil from Indonesia was the largest contributor to deforestation, followed by Brazil due to cattle grazing.
- The report by Trase, commissioned by Global Witness, found that the U.S. continues to import deforestation-linked commodities while awaiting the passage of the FOREST Act, which aims to prohibit imports of products linked to illegal deforestation.
- Experts emphasize the need for action from companies, governments, financial institutions and citizens to stop commodity-driven forest loss, urging support for smallholders, increased transparency in supply chains, and the passage of the FOREST Act in the U.S.
Bioacoustics and AI help scientists listen in on elusive Australian cockatoos
- Researchers in Australia have deployed acoustic recorders and artificial intelligence to study, monitor and protect eastern pink cockatoos (Lophochroa leadbeateri leadbeateri).
- The technology led scientists at the Queensland University of Technology to a previously unknown breeding hollow of the birds.
- Pink cockatoos, with eastern and western subspecies, are endemic to Australia and hard to monitor because they live in remote arid and semiarid ecosystems.
- With the research, scientists say they hope to understand more about where the birds live and how they react to changes in rainfall and temperature.
2024 Goldman Prize Winner Murrawah Johnson: First Nations must be at the forefront of creating change
- Murrawah Maroochy Johnson, an Indigenous Wirdi woman and Traditional Owner from the Birri Gubba Nation, has been awarded the 2024 Goldman Environmental Prize in the category of climate and energy.
- Johnson is the co-founder of Youth Verdict, an advocacy group that successfully won a court case against Waratah Coal in Queensland, Australia. She joins the Mongabay Newscast to discuss the significance of this case for First Nations rights in Australia, as well as the legal implications for similar cases in the future.
- The case Waratah Coal Pty. Ltd. vs. Youth Verdict Ltd. & Ors (2022) resulted in the Land Court of Queensland recommending a rejection of a mining lease in the Galilee Basin that would have added 1.58 billion metric tons of carbon dioxide to the atmosphere over its lifespan.
- The case also set multiple precedents in Australia, including being the first successful case to link the impacts of climate change with human rights, and the first to include “on-Country” evidence from First Nations witnesses.
Meet the 2024 Goldman Environmental Prize Winners
- This year marks the 35th anniversary of the prestigious Goldman Environmental Prize, which honors one grassroots activist from each of the six inhabited continents.
- The 2024 prize winners are Alok Shukla from India, Andrea Vidaurre from the U.S., Marcel Gomes from Brazil, Murrawah Maroochy Johnson from Australia, Teresa Vicente from Spain, and Nonhle Mbuthuma and Sinegugu Zukulu from South Africa.
Rewilding program ships eggs around the world to restore Raja Ampat zebra sharks
- A rewilding project aimed at saving endangered zebra sharks (Stegostoma tigrinum is sending eggs from aquarium sharks more than 12,000 kilometers (7,500 miles) away to nurseries in Raja Ampat.
- After hatching, the young sharks are kept in tanks until they are strong enough to release into the wild.
- Researchers hope to release 500 zebra sharks into the wild within 10 years in an effort to support a large, genetically diverse breeding population.
- A survey estimated the zebra shark had a population of 20 spread throughout the Raja Ampat archipelago, making the animal functionally extinct in the region.
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.
Studies still uncovering true extent of 2019-20 Australia wildfire catastrophe
- Australia’s 2019-20 bushfires burned with unprecedented intensity through a total of 24 million hectares (59 million acres), an area the size of the U.K.
- New research shows total costs incurred to the tourism industry from that single bushfire season may be 61% higher than previously calculated.
- Up to 1.5 billion wild animals may have perished in the fires, and new research is uncovering the cost to individual species as a result of the fires.
- One study published shows 15% of all known roost locations of the gray-headed flying fox, Australia’s largest bat species, may have been directly impacted by the fires.
‘Corals dying’ as yet more bleaching hits heat-stressed Great Barrier Reef
- Both aerial and in-water surveys have shown that the southern section of the Great Barrier Reef is undergoing extensive coral bleaching.
- Surveys have also shown “limited bleaching” in the northern part of the Great Barrier Reef.
- However, scientists and reef managers plan to conduct more air and in-water surveys to further assess the coral bleaching across all parts of the Great Barrier Reef.
- Scientists suspect but have not yet confirmed that a seventh mass bleaching event since 1998 is currently underway; the last mass bleaching event on the Great Barrier Reef happened in 2022.
New funding boosts AI-enabled wildlife identification project in Australia
- An artificial intelligence project to identify native species from camera-trap images in Australia has received a A$750,000 ($492,000) grant from the government.
- The project by the conservation nonprofit Australian Wildlife Conservancy has already trained the AI model to identify 44 species from camera-trap images, from native animals such as kangaroos and dingoes, and invasive ones like cats and foxes.
- With the new funding, the team at AWC aims to scale up the model to be able to identify 120 species; the model can also be applied to alert land managers about invasive predators that are harmful to native species.
- Camera traps continue to be one of the most widely used technologies for biodiversity surveys, but the analysis of the thousands of images generated by camera traps remains a major bottleneck.
Activists urge Australia to end lucrative links to Myanmar junta’s mines
- Pro-democracy activists urge Australian government action against domestic companies they say are funding Myanmar’s military junta, citing environmental and human rights abuses in the country’s mining sector.
- Two advocacy groups criticized the slow pace of Australian sanctions, calling on Canberra to follow Western counterparts in targeting state-owned natural resource enterprises there.
- A recent Justice For Myanmar report identifies Australian-linked companies allegedly supporting the junta through mining activities and related services, prompting demands for coordinated international action.
Can bioplastics shape a greener future?
- Humanity produces roughly 400 million metric tons of plastic each year, yet only recycles or reuses 9%, at most, of all the plastic collected.
- The global waste crisis is evident in the immense amount of plastic trash that ends up polluting the land, water, atmosphere, wildlife, and even our bodies.
- While nations are currently locked in negotiations to design a global treaty meant to rein in plastic production and address plastic pollution, researchers are working to develop fully biodegradable and naturally occurring plastic polymers known as polyhydroxyalkanoates (PHAs).
- In this episode of Mongabay’s “Problem Solved” video series, we take a look at how PHAs are made, and what else experts say needs to be done to combat the global plastic pollution crisis.
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.
Mongabay’s top 10 podcast episodes of 2023
- It was a packed year on Mongabay’s podcast calendar, with a new season of “Mongabay Explores” taking a deep dive into the Congo Basin.
- At the same time, the Mongabay Newscast continued publishing conversations with leading researchers, authors and activists, and it introduced a new co-host, Rachel Donald.
- Our top 10 list includes examinations of the Congo Basin’s cobalt mining industry, a conversation with a Pulitzer Prize-winning author, a botanist discussing the worrying decline of botany education, and a National Geographic photographer’s project highlighting the key role of traditional ecological knowledge for Indigenous communities and conservation.
Glencore’s coal expansion plans face shareholder and Indigenous opposition
- Swiss-based mining giant Glencore says it plans to challenge the proposed listing of a heritage site, the Ravensworth Homestead, that could deter the planned expansion of its Glendell coal mine.
- Glencore, the largest coal producer in Australia, faces criticism from shareholders for its lack of transparency on how it plans to meet its climate targets, especially in light of proposed thermal coal mine expansions in the country.
- Listing the homestead, which is a culturally significant site for the Indigenous Wonnarua people, is now being reconsidered by heritage officials after a process that sources say has dragged on.
- The Glendell mine is one of several that could increase their emissions under a loophole in the government’s revised “safeguard mechanism” that’s intended to bind the mining sector to a reduction in emissions.
Lethal or not? Australia’s beaches are a crucible for shark control methods
- For decades, Australia’s east-coast states have attempted to keep beachgoers safe from sharks by deploying entangling shark nets and culling species deemed dangerous.
- Recent figures published by the state of New South Wales reveal that almost all the animals caught in the nets during the 2022/23 summer season were “nontarget” species, including turtles, dolphins and endangered shark species, the majority of which died due to entanglement in the nets.
- In contrast, the west-coast state of Western Australia has abandoned a shark culling regime in favor of nonlethal alternatives, such as drone monitoring and “eco barriers,” swimming enclosures that keep marine life out but do not risk entanglement.
- Despite calls from environmental groups to exclusively adopt nonlethal technologies, shark control programs are continuing in both New South Wales and its northern neighbor, Queensland, during the 2023/24 Australian summer.
Australia crackdown on climate protesters grows amid fight against gas project
- The Indigenous ancestral land of Murujuga in Western Australia is home to the world’s oldest and largest collection of petroglyphs, which would be partially destroyed by the country’s biggest fossil fuel project, the Burrup Hub, owned by Woodside Energy.
- As the company argues more gas is needed, direct action tactics by protesters, like releasing non-toxic stench gas or painting on art, have erupted across the state, as well as crackdowns by the police who have begun imposing the strongest form of charges on activists — some facing up to 20 years in prison.
- This is on trend with a general increasing intolerance toward environmental protesters in Australia and an uptick in the use of direct action by protesters who feel the time is running out to meet climate targets and protect endangered species.
- Environmentalists and researchers worry the project will endanger marine life through seismic blasting and say studies show it is not necessary to meet the country’s energy needs.
With record ocean temps, is the Great Barrier Reef facing catastrophe?
- The inaugural international edition of the famed South by Southwest (SXSW) film festival and conference took place from October 15-22, 2023 in Sydney and Mongabay spoke with some of the most interesting presenters there.
- On this edition of the Mongabay Newscast, multiple guests working in coral reef conservation, kelp reforestation and sustainable agriculture detail their projects and challenges they’re tackling.
- Like the catastrophic Great Barrier Reef bleaching event of 2016, if the current conditions line up just right, “we could lose a huge part of the reef by February,” says guest Dean Miller of the Forever Reef Project, which is now racing to add the final coral specimens to its “biobank.”
- Guests also include John “Charlie” Veron from the Forever Reef Project, Mic Black from Rainstick, and Adriana Vergés from the Kelp Forest Alliance.
What does land mean to Australia’s Indigenous groups fighting logging?
- Many Indigenous Gumbaynggirr people in Australia feel an intimate connection to their ancestral lands, which holds the trees, animals, ancestral spirits and creation stories that form a core part of their identity and sense of belonging.
- This landscape, part of the Newry State Forest in New South Wales, Australia, is facing a logging project by the state-owned Forestry Corporation that threatens the habitat of the vulnerable koala species — also a cultural totem.
- Gumbaynggirr protesters resisting logging plans say they believe every part of the world is in deep relationship with each other, including humans to nature and the land. Their cultural duty to protect totems, they say, pushes them to try to stop extractive industries.
- In this piece, Indigenous Gumbaynggirr protesters explain what land — this piece of the Earth — means to them.
In the chain of species extinctions, AI can predict the next link to break
- Scientists at Flinders University in Australia have developed a machine-learning model that predicts which species are at risk of extinction if another species is removed from an ecosystem or an invasive one is introduced.
- Trained on data on how species interact with each other, the model could serve to alert conservation managers on which vulnerable species to focus on, the developers say.
- They tested the model successfully in Australia’s Simpson Desert, where it accurately predicted which species invasive foxes and cats preyed on.
- However, the shortage of data on species interactions, along with the possible biases that arise, are gaps that still need to be filled in the model.
New Tree Tech: Cutting-edge drones give reforestation a helping hand
- This four-part Mongabay mini-series examines the latest technological solutions to help tree-planting projects achieve scale and long-term efficiency. Using these innovative approaches could be vital for meeting international targets to repair degraded ecosystems, sequester carbon, and restore biodiversity.
- Restoring hundreds of millions of hectares of lost and degraded forest worldwide will require a gigantic effort, a challenge made doubly hard by the fact that many sites are inaccessible by road, stopping manual replanting projects in their tracks.
- Manual planting is labor-intensive and slow. Drone seeding uses the latest in robotic technology to deliver seeds directly to where they’re needed. Drones can drop seeds along a predefined route, working together in a “swarm” to complete the task with a single human supervisor overseeing the process.
- Drone-dropped seed success rates are lower than for manually planted seedlings, but biotech solutions are helping. Specially designed pods encase the seeds in a tailored mix of nutrients to help them thrive. Drones are tech-intensive, and still available mostly in industrialized countries, but could one day help reseed forests worldwide.
Degraded, but not defunct: Modified land still has wildlife value, study says
- Researchers studying how species respond to repeated and rapid land cover changes say more focus needs to be placed on preserving the biodiversity value of human-dominated landscapes.
- With much of the world’s intact ecosystems now modified by humans, the study warns that without careful management, species will be lost each time land is converted from one land-use type to another, such as when forestry is transitioned to plantation or agriculture.
- The researchers call for biodiversity impact assessments when land is proposed for conversion, regardless of whether it is intact primary habitat or considered “degraded” land.
- They also recommend the identification, preservation and restoration of natural features of landscapes, such as forest fragments, large and old trees, and wetlands, which can serve as vital refuges for species between successive land conversions.
Climate change is no joke for Australians, says award-winning comedian Dan Ilic
- Despite citizens voting out the Scott Morrison-led government of Australia in 2022, Dan Ilic says there’s still a lot of talk around climate change policy with not enough action to meet national climate targets.
- Known widely for his epic billboards appearing in New York’s Times Square during the COP26 climate summit satirizing Australia’s lack of seriousness at the conference, Ilic is host of the award-winning Australian comedy/climate-focused podcast “A Rational Fear” and spoke with the Mongabay Newscast in Sydney about the landscape surrounding climate policy in the country today.
- He also shares his thoughts on victories for Indigenous communities in the Tiwi Islands and the Galilee Basin, both in Australia, where massive fossil fuel proposals were recently blocked.
Australia bushfires may have caused global climate phenomenon La Niña: Study
- The 2019-2020 Australian bushfires threw up so much ash into the atmosphere that it resulted in a cooling of the southern Pacific and hence a La Niña climate phenomenon, a new study says.
- Volcanic eruptions that send vast ash plumes into the atmosphere are thought to trigger La Niña events, but this is the first time a fire has been recorded as doing so.
- La Niña can produce ruinous weather conditions in contrasting ways, from additional hurricanes in North America and droughts in the Horn of Africa, to crop failures in South America.
- The study’s findings call into question the assumption in current climate models that biomass emissions — including from bushfires — will decrease over time.
Kelp forests contribute $500 billion to global economy, study shows
- New research suggests that kelp forests generate up to $562 billion each year by boosting fisheries productivity, removing harmful nutrients from seawater, and sequestering carbon dioxide.
- The findings suggest that kelp forests are about three times more valuable than previously believed, contributing the equivalent of Sweden’s entire GDP to the global economy.
- However, experts say that kelp forests are generally overlooked and undervalued, and that many of these ecosystems are under threat worldwide.
After 150 years of damage to people and planet, Rio Tinto ‘must be held to account’ (commentary)
- The giant mining company Rio Tinto marks its 150th anniversary this year, yet activists say it has a dirty history.
- As the company gathers on April 6 for its Annual General Meeting, advocates are pointing out that after all this time, its shareholders should grapple with the company’s legacy of damaging people and planet.
- “Companies like Rio Tinto must be held accountable for the harm they cause,” a new op-ed argues, and a new law proposed in the UK – the Business, Human Rights and Environment Act – would allow people to take companies like it to court more easily for environmental and human rights abuses committed abroad.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
As oceans warm, temperate reef species edge closer to extinction, study shows
- New research found that most Australian shallow reef species, including fish, corals, seaweeds and invertebrates, experienced population declines over a decade, mainly in response to warming events driven by human-induced climate change.
- While scientists recorded species decline across Australian waters, some of the most pronounced changes occurred on the temperate reefs of southern Australia, a region that has received less conservation attention than tropical reefs.
- The authors say temperate reefs could be in greater danger of extinction than tropical species, leading to calls for increased conservation efforts for these threatened ecosystems.
‘Plasticosis’: the new disease killing seabirds and likely many other species
- Scientists have identified a new fibrotic disease called “plasticosis” in flesh-footed shearwaters, a species that inadvertently consumes plastic.
- They found that plasticosis was even present in shearwaters with only a small quantity of plastic in their stomachs.
- While this plastic-related disease has thus far only been identified in flesh-footed shearwaters, experts say that nearly every organism — including humans — is being impacted by plastic in some way.
The Netherlands to stop paying subsidies to ‘untruthful’ biomass firms
- On December 5, 2022, Mongabay featured a story by journalist Justin Catanoso in which the first ever biomass industry insider came forward as a whistleblower and discredited the green sustainability claims made by Enviva — the world’s largest maker of wood pellets for energy.
- On December 15, citing that article and recent scientific evidence that Enviva contributes to deforestation in the U.S. Southeast, The Netherlands decided it will stop paying subsidies to any biomass company found to be untruthful in its wood pellet production methods. The Netherlands currently offers sizable subsidies to Enviva.
- Precisely how The Netherlands decision will impact biomass subsidies in the long run is unclear. Nor is it known how this decision may impact the EU’s Sustainable Biomass Program (SBP) certification process, which critics say is inherently weak and unreliable.
- Also in December, Australia became the first major nation to reverse its designation of forest biomass as a renewable energy source, raising questions about how parties to the UN Paris agreement can support opposing renewable energy policies, especially regarding biomass — a problem for COP28 negotiators to resolve in 2023.
Australia rejects forest biomass in first blow to wood pellet industry
- On December 15, Australia became the first major economy worldwide to reverse itself on its renewable classification for woody biomass burned to make energy. Under the nation’s new policy, wood harvested from native forests and burned to produce energy cannot be classified as a renewable energy source.
- That decision comes as the U.S., Canada, Eastern Europe, Vietnam and other forest nations continue gearing up to harvest their woodlands to make massive amounts of wood pellets, in order to supply biomass-fired power plants in the UK, EU, Japan, South Korea and elsewhere.
- In the EU, forest advocates continue with last-ditch lobbying efforts to have woody biomass stripped of its renewable energy designation, and end the ongoing practice of providing large subsidies to the biomass industry for wood pellets.
- Science has found that biomass burning releases more carbon dioxide emissions per unit of energy produced than coal. Australia’s decision, and the EU’s continued commitment to biomass, creates a conundrum for policymakers: How can major economies have different definitions of renewable energy when it comes to biomass?
Negotiations to conserve Antarctic Ocean end in stalemate on many issues
- The 41st annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with conserving marine life in the Southern Ocean and managing fisheries there, ended Nov. 4 with little progress made on several key issues.
- In 2009 CCAMLR committed to creating a network of marine protected areas to preserve Antarctic ecosystems. It established one that year and another in 2016, but since then China and Russia have repeatedly blocked the creation of additional protected areas, as well as other conservation-related measures.
- The commission also failed to reach the consensus required to enact new regulations for the krill and toothfish fisheries, or to protect a vast nesting area for icefish discovered earlier this year.
- CCAMLR members did agree to designate eight new vulnerable marine ecosystems, areas home to slow-growing organisms such as corals, sponges, brittle stars and feather stars that are now permanently protected from bottom fishing.
Plastic impacts a grossly underestimated ‘one-two punch’ for seabirds: Study
- That plastic pollution is harmful to marine life, including seabirds, is well known, but recent research finds that the impacts may be “grossly underestimated” and that plastics can affect multiple organs.
- A new study investigated plastic ingestion by flesh-footed shearwaters and found that — as was determined in past research — initial consumption can harm the stomach. New evidence also showed that impacts are far more expansive, and may cause ongoing health problems distributed throughout body organs.
- Some forms of tissue damage detected by the new research suggest that plastic particles may also act as chemical pollutants, though this requires further study.
- Plastic pollution is a massive growing problem for the world’s oceans and marine life. Earlier this year, researchers announced that the global planetary boundary for novel entities — including plastics — has been surpassed, threatening Earth’s operating systems and life as we know it.
Indigenous leader’s court win halts one of Australia’s ‘dirtiest gas projects’
- Indigenous community members from the Tiwi Islands off the northern coast of Australia took Santos Limited to court, arguing that the company did not adequately consult traditional owners in its plans to drill in the Barossa offshore gas field.
- A federal court threw out the approval granted by Australia’s offshore energy regulator, noting that all relevant stakeholders were not consulted.
- The drilling to develop the $3.6 billion Barossa gas project could threaten the Tiwi peoples’ food sources, culture and way of life, opponents say.
- If the Barossa project goes ahead, it could become one of Australia’s dirtiest gas projects emitting around 5.4 million metric tons of carbon dioxide yearly, estimates from the Institute for Energy Economics and Financial Analysis show.
‘Amped-up citizen science’ to save the world: Q&A with Conservation AI Hub’s Grant Hamilton
- Conservation AI Hub uses drones and artificial intelligence to detect koalas that survived the Australian bushfires of 2019 and 2020.
- The initiative is now working with communities in Australia to train them on using the technology by themselves.
- Director Grant Hamilton says it’s imperative to make technology more accessible so that more citizens can engage and participate in global conservation efforts.
In a hotter, drier climate, how serious is fire risk to island seabirds?
- A new study suggests that fires on remote islands in southwest Australia pose a rising threat to short-tailed shearwaters and other seabirds as climate change creates hotter and drier conditions.
- In 2021, a research team led by Jennifer Lavers surveyed an island in Western Australia’s Recherche Archipelago a year after a fire event, and found little evidence that short-tailed shearwaters had successfully bred after the fire, ignited by a lightning strike, had swept over most of the island.
- Lavers and her research team suggest that Indigenous-led methods of controlled burning could help reduce the risk of catastrophic fires that would endanger seabirds.
- However, a seabird and island expert not connected with the study disagrees that fire currently poses a major threat, since seabirds have been known to rebound from fires, even after the loss of their fledglings and burrows.
Turtle DNA database traces illegal shell trade to poaching hotspots
- Critically endangered hawksbill turtles have been hunted for their patterned shells for centuries to make tortoiseshell jewelry and decorative curios.
- The exploitation and trade pushed the species to the brink of extinction; despite international bans on killing and trading the turtles and their parts, persistent demand continues to stoke illegal trade.
- Experts say they hope the launch of a new global turtle DNA database coupled with DNA-based wildlife forensics techniques can turn the tables on poachers and illegal traders.
- The new resource, called ShellBank, will enable law enforcement authorities to trace confiscated tortoiseshell products to known turtle breeding locations to help them crack down on poaching and the illegal trade.
