Students and scientists collaborate to maintain Navajo Nation forests
- Scores of saplings are choking out some pinyon pine forests in the southwestern United States, smothering the grasses that support ranchers.
- Researchers thinned small trees from a pinyon woodland in the Navajo Nation, creating an open forest that supports understory plant growth.
- Tribal and nontribal researchers and students from Northern Arizona University and Diné College on the Navajo Nation collaborated on the project.
Eastern U.S. floods could persist longer toward the end of the century
- Fifty years from now, floods in the eastern half of the United States will last longer as climate change creates warmer and wetter weather patterns, a new study suggests.
- Floods will last longest in the winter, the analysis predicts, marking a shift in damaging flood seasons.
- The trends underscore a need to renovate levees and dams, flood channels, and other infrastructure to protect residents and cities, researchers say.
Controversial U.S. Supreme Court decision threatens the country’s inland wetlands with new development, study says
- In its May 2023 decision Sackett v. Environmental Protection Agency, the U.S. Supreme Court all but gutted the nation’s Clean Water Act of 1972, only maintaining protections for large waterways and opening inland wetlands for development.
- An estimated 7 million to 36 million hectares (17 million to 90 million acres) of nontidal wetlands may have lost federal protections, according to a new analysis.
- Filling wetlands would harm downstream water quality, eliminate critical ecological habitats and elevate the risk of flooding, concerned researchers say.
- The largest wetland areas at risk in the U.S. are near the Gulf of Mexico and Atlantic Ocean coasts and around the inland Great Lakes.
New research maps microbial life in U.S. rivers
- With the help of the public, scientists mapped microbial life across 90% of U.S. watersheds by analyzing genetic data from approximately 100 rivers, creating the first comprehensive catalog of U.S. river microbes.
- The study identified six core microbes present in all studied rivers, and these organisms all harness sunlight for energy, highlighting a fundamental pattern in river ecosystems.
- River microbes interact significantly with pollutants, breaking down microplastics and showing increased antibiotic resistance near wastewater treatment plants, revealing how human activities affect river health.
- River size, more than latitude or carbon levels, determines which microbes are present, with communities changing predictably as rivers flow from small headwaters to larger waterways.
Desalination plants proposed for Texas Gulf Coast spur broad opposition
- Corpus Christi is a city on the Texas Gulf Coast located close to water hungry industries in the drought plagued state, attracting multiple proposals to build desalination plants that would turn saltwater into freshwater for plastic manufacturers and other industrial end users.
- Desalination uses a lot of energy but also produces brine, which can be twice as salty as seawater and can contain elevated levels of heavy metals.
- This brine is set to be pumped back into Corpus Christi Bay or further out into the Gulf of Mexico, causing an array of stakeholders from the fishing community to birdwatchers to oppose the ‘desal’ plants.
- The director of one of the grassroots action groups discusses the situation in an interview with Mongabay.
Rappahannock Tribe first in US to enshrine rights of nature into constitution
- The Rappahannock Tribe in Virginia has become the first tribal nation in the U.S. to adopt a tribal constitution that grants legal rights to a river, specifically protecting the Rappahannock River’s rights to exist, flourish, and maintain clean water.
- The constitutional provisions allow the tribe and individual tribal members to bring legal cases on behalf of the river itself, with a tribal court system planned for 2025 to enforce these rights.
- This historic move comes from a tribe that has lived alongside and been sustained by the river for thousands of years, with Chief Anne Richardson describing the river as “the Mother of our Nation,” which has provided physical, cultural and spiritual nourishment to the tribe.
- The Rappahannock’s actions are part of a rights-of-nature movement that includes Ecuador’s constitutional recognition of nature’s rights in 2008 and New Zealand’s granting of legal personhood to the Whanganui River in 2017.
As global fire risk rises, modern homes become toxic plastic traps
- In the 21st century, petrochemical-based building materials and furnishings have replaced traditional wood, fabric and metal materials in homes worldwide. But plastics are more flammable and release persistent toxic chemicals when burned or exposed to high heat.
- Also over the last 25 years, wildfires have multiplied and intensified due to global warming, and often now jump the wildland-urban interface, burning whole neighborhoods and leaving behind a dangerous toxic home legacy.
- Homeowners whose houses survive such wildfires are often stunned to learn that their homes are a toxic health threat, unlivable and a total loss.
- The multibillion-dollar production and wide-ranging export of plastic building materials and home furnishings, and the dramatic surge in wildfires, has made this a global problem impacting communities in the U.S., China, Australia, Brazil, Canada, Portugal and beyond.
Bobcats are back, and they’re helping protect people from zoonotic disease
- In the last 125 years, bobcats have recovered significantly from extremely low numbers, with several million individuals found throughout North America today.
- Living at the interface of urban and rural environments, bobcats face many human-caused dangers, including loss of habitat to roam, automobiles, and rodent poisons.
- Bobcats help reduce the spread of diseases from animals to humans partly because they and other large mammals are poor disease vectors. Bobcats also prey on the small rodents that easily transmit pathogens.
- It’s legal to hunt bobcats in most of the United States. California, which has for five years closed the bobcat season, may reinstate hunting in 2025. Some researchers suggest that regulators should more carefully consider the role thriving wildcat populations play in protecting human communities from zoonotic diseases before expanding hunting.
U.S. policy experts confident of future climate action despite Trump election
- In 2015, the world came together to achieve the landmark Paris climate agreement. But in 2016, Donald Trump’s ascendency to the U.S. presidency stunned the world, as he promised to withdrew the U.S. from the Paris accord and moved to disrupt action on climate change.
- The Biden administration worked to reverse that damage, with the U.S. again taking a leadership role in global climate summits and passing the Inflation Reduction Act, one of the most ambitious U.S. laws ever to combat global warming and boost the post-carbon economy.
- Now, with Trump elected again, the world stands ready for his climate denialism, and his likely withdrawal of the U.S. for a second time from the Paris Agreement. Global momentum is expected to continue unabated, with alternative energy thriving, Brazil hosting COP30 in 2025, and China and the EU doubling down on climate action.
- In the U.S., “Just as we did during the last Trump administration, we are going to put a focus on our work with cities and with states and many private-sector leaders who stood tall then and stand tall now,” said Gina McCarthy, EPA administrator during Barack Obama’s second term, and managing co-chair of America Is All In, an NGO.
Will ‘Trump Part II’ be the wakeup call needed toward more effective conservation? (commentary)
- Conservation has always been an uphill battle but this has never deterred conservationists from continuing to struggle to make a difference, even if their strategies have not halted the extinction crisis. The momentum coming out of the recent global biodiversity conference in Colombia, despite its shortcomings, was badly needed to push on.
- And then Trump was re-elected as US President. Is this at last the wake-up call the conservation sector needs to realize that radical change is required?
- “Now [we] we can say it even more bluntly: conservation has never truly addressed the fundamental power structures that lead to biodiversity loss. And it let itself believe that under Biden it could go back to doing what it had always done: expand protected areas and work with business-as-usual economic interests,” a new op-ed says in arguing for a more radical approach.

Do forest conservation pledges work? (commentary)
- The New York Declaration on Forests was agreed with great hope 10 years ago, but the world missed its 2020 target and is off track to end deforestation by 2030. Does this mean that forest pledges don’t work?
- It would be naive to expect pledges like it to quickly resolve decades long economic and political battles over land: their effect is limited without changes to forest funding, because forest clearance is usually driven by economic calculation.
- “The NYDF has not made history, but it did help redirect attention in a distracted world and create a benchmark for progress. Without it and the Glasgow Declaration, there would be less support for the many communities and institutions who are helping protect the two thirds of remaining tropical forests which are still standing,” a new op-ed states.

U.S. toughens stance on plastics production in run-up to key treaty summit
- The United States has revised its position regarding ongoing U.N. plastics treaty negotiations. The U.S. originally wanted a treaty based on voluntary nation-by-nation compliance, with the emphasis on improved plastics recycling and reuse. The new U.S. position recognizes the need to regulate plastics over their entire life cycle, including production.
- Analysts say the shift in U.S. position could help soften the positions of China, Russia, India and Saudi Arabia, nations that have vigorously opposed efforts to regulate production. All of these nations are major petrochemical and/or oil producers.
- The U.N. Intergovernmental Negotiating Committee on Plastic Pollution is set to meet from Nov. 25-Dec. 1 in Busan, South Korea, where it plans to finalize treaty language. However, failing this, the treaty talks might continue next year.
- The U.S. election throws doubt on what the nation’s final position might be after the treaty language is finalized. It seems likely that a Kamala Harris administration would press for treaty ratification, while a Donald Trump administration could try to derail a final agreement (as was the case with the Paris climate agreement), especially if it regulates plastics production.
Salmon is ‘everything’ for Lummi Nation highlighted in new PBS documentary
- A new documentary, Scha’nexw Elhtal’nexw Salmon People: Preserving a Way of Life, premieres on PBS Nov. 4, following two Lummi families as they maintain fishing traditions amid declining salmon populations.
- In an interview, co-director Beth Pielert and Lummi fisher Tah Mahs Ellie Kinley discuss the film’s origins, salmon’s importance to Lummi culture, and current threats to wild salmon populations.
- For the Lummi people, salmon fishing is described as “everything” — it’s not just an activity but the foundation of their identity, with families tracing their lineage through traditional reef net sites and finding spiritual fulfillment in continuing ancestral practices.
- The filmmakers hope viewers will walk away with both understanding and hope, recognizing that while salmon face serious threats from fish farms and industrial development, there’s still time to protect these resilient fish that are essential to Lummi cultural survival.
50 years of geographic insight: In interview with Jack Dangermond on Esri’s journey and the future of GIS
- The digital mapping platforms developed by Esri, including ArcGIS, have revolutionized conservation and environmental planning, management and policymaking. Esri co-founder Jack Dangermond calls geographic information systems (GIS) “a sort of intelligent nervous system for our planet at a time when humanity desperately needs one to address the environmental and humanitarian crises at hand.”
- He credits Esri’s success to a sustainable trajectory of heavy investment in R&D, not being beholden to outside investors, and providing discounted and free use of its software to environmental nonprofits.
- In this interview with Mongabay founder and CEO Rhett A. Butler, Dangermond says that technology, amid the current fractured political climate, should be employed to encourage understanding rather than dwell on divisions.
- The text of the interview has been edited for clarity and flow.
When bats die, farmers use more pesticides & infant deaths rise, study shows
- New research shows that when bat populations crashed due to white-nose syndrome, farmers increased their insecticide use by 31%, leading to a nearly 8% rise in infant mortality rates in affected U.S. counties.
- The study, which examined 245 counties from 2006 to 2017, estimates total damages at $39.4 billion.
- White-nose syndrome, a fungal disease first detected in the northeastern U.S. in the mid-2000s, has now spread to 40 states and nine Canadian provinces, causing more than 90% population declines in three bat species.
- While conservation efforts, including vaccines and fungus removal, are underway, the situation could worsen, as 52% of North American bat species are at risk of extinction within the next 15 years.
New survey puts human face on pollution caused by U.S. wood pellet mills
- A new groundbreaking survey highlights the human toll from pollution and other quality of life impacts connected to those living near the forest biomass industry’s wood pellet mills in the U.S Southeast.
- Door-to-door interviews were conducted by a coalition of NGOs, with 312 households surveyed in five mostly poor, rural and minority communities located near pellet mills operated by Drax and Enviva, two of the world’s largest pellet makers.
- In four of the five newly surveyed communities, 86% of households reported at least one family member with diseases or ailments, which they say are related to, or made worse by, pellet mill pollution. 2023 research found that pellet mills emit 55 toxic pollutants that largely impact environmental justice communities.
- The wood pellet industry says the survey was not scientifically rigorous and that its members strive to control pollution and improve the local economies in communities where they work.
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.

Cambodian logging syndicate tied to major U.S. wood flooring supply chains
- Cambodian companies producing engineered hardwood flooring for the U.S. market are getting their timber from a company described as a cartel that’s been repeatedly accused of illegally logging inside protected areas.
- Angkor Plywood is the sole supplier of plywood to flooring manufacturers based in the Sihanoukville Special Economic Zone, and claims the wood comes from its acacia and eucalyptus plantations.
- However, watchdog groups, industry insiders and independent media, including Mongabay, have long documented evidence of Angkor Plywood and its supplier, Think Biotech, felling tropical hardwoods inside Prey Lang Wildlife Sanctuary.
- AHF Products, which claims to be the biggest U.S. wood flooring manufacturer, runs a factory in the Sihanoukville SEZ, but denies any protected wood entering its supply chain — a claim industry veterans question, given Angkor Plywood’s notoriety.
Largest dam removal ever, driven by Tribes, kicks off Klamath River recovery
- The largest dam-removal project in history was completed in October, freeing 676 kilometers (420 miles) of the Klamath River and its tributaries in California and Oregon.
- The project involved removing four dams, built between 1918 and 1964 to provide electricity. They had devastating effects on salmon populations and tribal communities, leading to a decades-long, tribe-led movement for their removal.
- The $450 million project involved complex engineering to remove the dams and, now, to restore the river ecosystem, including replanting native vegetation and reshaping the river channel, incorporating tribal knowledge to improve habitats for salmon and other species.
- The first chinook salmon in more than 60 years are already spawning above the former Iron Gate dam and a fall-run Chinook salmon was identified in Oregon for the first time in more than 100 years. Experts expect coho salmon populations to recover in six to 12 years and Chinook salmon in 15 to 20 years in what was once the third-largest salmon producing river in the contiguous U.S.
Delay of EU Deforestation Regulation may ‘be excuse to gut law,’ activists fear
- In a surprise move, the European Commission has proposed a 12-month delay in implementation of the EU’s groundbreaking deforestation law, which was slated to go into effect in January 2025.
- The European Parliament still needs to approve the delay, but is expected to do so. The law is meant to regulate global deforestation caused by a range of commodities from soy to coffee, cattle, cocoa, palm oil, rubber and wood products, including industrial-scale wood pellets burned to make energy.
- Commodity companies, including those in the pellet industry, say the law’s certification requirements are onerous and the 2025 start date is too soon for compliance. The industries are supported by commodities-producing nations such as Brazil, Indonesia and the United States (a primary source of wood pellets).
- Forest campaigners, including those opposing tree harvests for wood pellets, fear that delay of the EU Deforestation Regulation (EUDR) will offer commodity companies and exporting nations time to water down the law meant to protect native forests, carbon storage and biodiversity, and delay the worst climate change impacts.
Poll shows voters agree next U.S. President must do more for wildlife and conservation (commentary)
- Ahead of a pivotal election in the U.S., new polling data on views about wildlife conservation — and even climate change — revealed here offer a stark contrast to the partisan narratives often used to separate Americans.
- While the nation is certainly divided on many issues, there is encouraging common ground when it comes to wildlife: 87% say a 2024 presidential candidate’s commitment to conservation is important, a stat which includes 82% of Republicans — a 14% increase from 2020.
- “These increases are stunning, and we expect to see even more Republicans and Democrats coming together on these issues in the future. It’s all part of a broader trend where more Americans are connecting with nature. Our national parks are seeing record attendance and many zoos and aquariums across the United States are also,” a new op-ed by the President & CEO of the Indianapolis Zoological Society says.

Controversial US marine geoengineering test delayed until next year
- The first-ever field test of ocean alkalinity enhancement in the United States was pushed back to 2025 due to shipping issues. But the geoengineering experiment has also run into public opposition from local environmentalists, commercial fishers and others.
- The test would dump sodium hydroxide (commonly called lye) off the New England coast to study its dispersal as a potential tool for sequestering CO₂.
- Opponents allege this small-scale geoengineering test could harm local wildlife, but researchers say the material will disperse within minutes.
- The scientists say they will also continue to reach out to local communities to alleviate fears over the study.
From prison psychologist to wildlife whisperer: Interview with Susan Eirich
- Dr. Susan Eirich’s journey from prison psychologist to wildlife conservationist began when she was asked to raise seven wolf puppies, leading her to found the Earthfire Institute, a sanctuary for rescued wildlife.
- Through her work and book, “Whispers from the Wild: An Invitation,” Eirich emphasizes the individuality of each animal, aiming to foster deeper connections between humans and wildlife.
- Eirich developed the concept of Reconnection Ecology, which focuses on cultivating profound experiences with nature to transform human perspectives and promote conservation efforts.
- Despite environmental challenges, Eirich says she maintains hope based on the resilience of life and encourages people to reconnect with nature to address both mental health and ecological crises.
Biden-Harris Administration must strengthen position on plastic reduction treaty (commentary)
- Final negotiations on a global plastics treaty are set to take place later this year, and since plastics manufacturing is a major user of fossil fuels, almost two hundred petrochemical industry lobbyists attended the previous round of negotiations in Ottawa.
- U.S. rhetoric there appeared to follow industry talking points, focusing on waste management and recycling while sidestepping any measures that would actually reduce the production of plastics, a new op-ed states.
- “The world needs U.S. leadership on plastic production reduction and the Biden-Harris Administration looks set to provide it. But it is now time to match these words with actions,” the author argues.

Will we be ready? Geoengineering policy lags far behind pace of climate change
- The history of geoengineering policymaking has been piecemeal over past decades, with U.N. bodies failing to create or implement rigorous binding international regulatory frameworks for geoengineering management, and with academia and think tanks delivering reports and recommendations that offer little definitive detailed regulatory guidance.
- Now, as climate change impacts intensify, the debate over what safe, effective national and international geoengineering policies should look like has intensified among academics, regulatory and advisory bodies and researchers.
- Meanwhile, scientists continue trying to find out if geoengineering (the deliberate altering of global atmospheric or oceanic conditions), can help cool off a dangerously warming planet without triggering harmful effects.
- Some warn geoengineering is too risky and want field research stopped. Others say research is urgently needed so decision-makers can understand geoengineering options and risks, so as to make informed choices. For now, few definitive road signs exist to guide policymaking.
Biden Administration mistakenly seeks delay of EU’s new deforestation regulation (commentary)
- “If the Biden Administration is serious about a global zero-deforestation agenda while helping US agribusiness, it should proactively support the EU Deforestation Regulation (EUDR) abroad, and double down at home on support for U.S. soy farmers and cattle ranchers to comply with the EUDR,” a new op-ed argues.
- Rather than support it, the U.S. is demanding that the European Union delay the EUDR, parroting arguments put forth by a small number of the U.S.’s least ethical producers, while ignoring thousands of companies and investors actively supporting the EUDR.
- “The U.S. has such limited deforestation exposure on soy and cattle it exports to the EU that most U.S. soy and cattle exports to Europe will likely benefit from the EUDR. The exact opposite of what Vilsack, Raimundo, and Tai’s letter argues.”
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
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.
A tribe once declared ‘extinct’ helps reintroduce salmon to the Columbia River
- For thousands of years, Kettle Falls was a vital salmon fishing ground for the Sinixt, but early 20th-century dam construction blocked salmon migration.
- Wrongfully declared extinct in Canada in 1956, the Sinixt fought for recognition and were officially acknowledged as Aboriginal Peoples of Canada in 2021.
- In 2023, the U.S. government signed a $200 million agreement with a coalition of tribes, including the Sinixt, to fund an Indigenous-led salmon reintroduction program into the Columbia River system above dams in Washington.
- Sinixt leaders say this project is an important effort to help right a historical wrong in the legacy that led to their “extinction” status, while many hope to one day join salmon efforts on their traditional territory in Canada.
As the world burns, can we learn to live with wildfire health risks?
- Climate change is driving or contributing to increased risk of extreme wildfires in many parts of the world, and experts say urgent action on climate change is needed.
- Finding ways to better manage land use can help reduce the likelihood and severity of wildfires: In landscapes where fire is natural, experts say we should bring back historic fire regimes through cultural burning and prescribed burns.
- Experts say more needs to be done to protect vulnerable populations from wildfire smoke, such as those with preexisting medical conditions, pregnant women, children and seniors, who may be impacted even thousands of miles from a fire’s source.
- Smoke prediction apps, early-warning systems and air filtration systems can help people reduce smoke exposure.
Studying snakes without rattling them? There’s now tech for that
- Scientists have used tiny, noninvasive radio transmitters and accelerometers to study the habitats and behaviors of red diamond rattlesnakes.
- While the radio transmitters help researchers keep track of the snakes, the accelerometers give them an in-depth understanding of the snakes’ physical movements as they hunt, eat and even mate.
- Historically, tracking snakes has involved surgically implanting telemetry radios into them, but this process is time-consuming and also risks infecting the animals.
- Red diamond rattlesnakes, native to southwest California in the U.S. and Baja California in Mexico, face increasing threats from habitat loss and vehicle strikes.
New approach to restore coral reefs on mass scale kicks off in Hawai‘i
- ʻĀkoʻakoʻa is a recently launched program aiming to restore a 193-kilometer (120-mile) stretch of coral reef along the west coast of Hawai‘i Island — one of the first to attempt restoration at a large scale.
- The project will identify individual corals with high thermal tolerance and other high-performance traits, then use them to breed genetically resilient coral larvae for release onto the reefs during natural spawning periods.
- ʻĀkoʻakoʻa is working with partners to reduce other stressors to the reefs, which can help corals be more resilient to rising sea temperatures, and drawing on Hawaiian traditional values of environmental stewardship.
- If successful, the project could provide knowledge for how to restore ailing reefs around the world suffering from an onslaught of human-driven thermal stress.
To conserve large landscapes like the Florida Wildlife Corridor, payments for ecosystem services could be key (commentary)
- Florida has among the fastest-growing state populations of any U.S. state, averaging 1,000 new residents daily which drives the development of natural ecosystems, timberlands, farms, and ranches, reducing habitats for wildlife and open spaces for people to enjoy.
- The Florida Wildlife Corridor aims to protect a continuous, 18-million-acre tract of land spanning the length of the state–from Alabama to the Everglades–to keep 50% of the state undeveloped and provide a much needed corridor for wildlife to move north, south, east or west.
- Because there may not be enough public money to acquire or put easements on all remaining unprotected land within the corridor, payments for ecosystem services agreements–which allow public or private interests to pay landowners for clearly defined ecosystem services like wildlife habitat or water catchment–may become an important component of financing the project, a new op-ed argues.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Restoring Indigenous aquaculture heals both ecosystems and communities in Hawai‘i
- The loko i’a system of native fishponds in Hawai‘i has for generations provided sustenance to Indigenous communities, supported fish populations in surrounding waters, and generally improved water quality.
- These benefits, long understood by native Hawaiians, have now been supported by scientists in a new study that looked at the restoration of one such fishpond.
- Unlike commercial fish farms, loko i‘a thrive without feed input and need little management once established — aspects that highlight the holistic thinking and values-based management behind them.
- The study authors say the finding is another step toward communicating Indigenous knowledge to support governmental decision-making, part of wider efforts across the archipelago to weave Indigenous and Western ways of knowing to heal both ecosystems and communities.
A tale of two frogs: The tough uphill battle for rediscovered species
- Some scientists worry that widespread enthusiasm over rediscovering lost or presumed-extinct species can underplay the rocky road to recovery that these species often face. Research suggests many rediscovered species have restricted ranges and small populations and remain highly threatened after their rediscovery.
- Rediscovered amphibians are particularly at risk due to their often-small ranges and risk of amphibian disease. A recently rediscovered harlequin frog species in Ecuador (tentatively identified as Atelopus guanujo), exemplifies challenges which can include intense funding competition and little legal protection or government support for imperiled species.
- The story of the rediscovered dusky gopher frog in the U.S. state of Mississippi illustrates how amphibians can benefit from strong conservation laws and government funding. Thanks to a long-term effort to conserve the dusky gopher frog, the species is now enroute to population recovery.
- Globally, rediscovered species face a range of outcomes — from full recovery to declines so severe populations aren’t genetically viable, or risk extinction due to single events. Outcomes vary based on funding, interest in conserving a particular species, and how much communities and institutions get involved in conservation.
Indigenous Alaskans drive research in a melting arctic
- In Utqiagvik, Alaska, the Iñupiat rely on whaling and subsistence hunting for the bulk of their diet, a practice dating back thousands of years.
- Powered by mineral wealth, the Iñupiat-run North Slope Borough Department of Wildlife Management employs a collaborative team of scientists and hunters.
- Though the arctic is warming nearly four times faster than the global average, the Iñupiat are confident in their ability to adapt their practices to changing conditions.
- The Department of Wildlife Management provides a potential model for collaborations between Indigenous peoples and western researchers — with Indigenous leaders in charge of funding and resource allocation.
A tiny desert fish hits a 25 year population high in one of Earth’s harshest environments
- The critically endangered Devils Hole pupfish population has reached a 25-year high of 191 fish, offering hope for the species that lives in the smallest known habitat of any vertebrate.
- Above water and SCUBA surveys conducted by scientists twice a year carefully monitor the pupfish population in Death Valley, Nevada, which has fluctuated dangerously in the past, dropping as low as 35 individuals in 2013.
- A landmark 1976 Supreme Court decision, informed by environmental science, protected the pupfish by limiting groundwater pumping that threatened its habitat, setting a precedent for science-based conservation policy.
- Despite recent success, the pupfish remains threatened by climate change impacts on the delicate desert ecosystem, as well as growing human demand for water resources in the region.
Cutting forests for solar energy ‘misses the plot’ on climate action (commentary)
- In many places, solar power projects are being sited on natural forestlands, even in America’s greenest state, Vermont. This ignores the fact that natural forests are key climate solutions, and also studies which indicate solar projects are best sited in abandoned industrial site, above parking lots, and on warehouse roofs.
- In the latest example, an industrial solar project is proposed to replace a tract of forest in Shaftsbury, in the southwestern corner of the Green Mountain State, despite community opposition.
- “Because climate change has been framed as an energy problem that can be solved with solar panels, well-meaning legislators have crafted incentives that [are] exploited by out-of-state investment firms like the one holding an axe over our trees,” a new op-ed explains.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Otter-preneurs: Female sea otters lead the way in tool use for survival
- In Monterey Bay, California, southern sea otters face food scarcity as their preferred prey, urchins and abalone, have declined due to climate change, overfishing and other environmental factors.
- To adapt, some sea otters, particularly females, use tools like rocks, shells and even discarded glass bottles to crack open harder-shelled alternative prey like snails, clams and mussels.
- A study of 196 tagged sea otters found that frequent tool users, especially females, could consume prey up to 35% harder than non-tool users and had significantly less tooth damage.
- The findings highlight the importance of behavioral flexibility in the face of ecological challenges and underscore the need to protect the threatened southern sea otter population, which plays a crucial role in maintaining the balance of coastal ecosystems.
UK’s Drax targets California forests for two major wood pellet plants
- Golden State Natural Resources (GSNR), a California state-funded nonprofit focused on rural economic development, along with the U.K.’s Drax, a global maker of biomass for energy, have signed an agreement to move ahead on a California project to build two of the biggest wood pellet mills in the United States.
- The mills, if approved by the state, would produce 1 million tons of pellets for export annually to Japan and South Korea, where they would be burned in converted coal power plants. The pellet mills would represent a major expansion of U.S. biomass production outside the U.S. Southeast, where most pellet making has been centered.
- GSNR promotes the pellet mills as providing jobs, preventing wildfires and reducing carbon emissions. California forest advocates say that cutting trees to make pellets —partly within eight national forests — will achieve none of those goals.
- Opponents note that the U.S. pellet industry is highly automated and offers few jobs, while the mills pollute rural communities. Clear-cutting trees, which is largely the model U.S. biomass firms use, does little to prevent fires and reduces carbon storage. Pellet burning also produces more emissions than coal per unit of energy produced.
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.
U.S. East Coast adopts ‘living shorelines’ approach to keep rising seas at bay
- Along the U.S. East Coast, communities are grappling with the dual destructive forces of rising sea levels and stronger storms pushed by climate change, resulting in effects ranging from ‘ghost forests’ of saltwater-killed coastal trees in the Carolinas, to inundations of New York City’s subway system.
- While the usual response has been to build higher seawalls and other concrete or rock structures, a natural approach that aims to protect coastal areas with natural assets that also create habitat and are generally cheaper and less carbon intensive — ‘living shorelines’ — is increasingly taking hold.
- State agencies and landowners alike are shoring up the shore with innovative combinations of locally sourced logs, rocks and native plants and shrubs to protect homes, dunes and beaches.
- In Maine, where a trio of powerful winter storms recently pummeled the coast, living shorelines designers are in growing demand.
Tribes turn to the U.N. as major wind project plans to cut through their lands in the U.S.
- Last week a United States federal judge rejected a request from Indigenous nations to stop SunZia, a $10 billion dollar wind transmission project that would cut through traditional tribal lands in southwestern Arizona.
- Indigenous leaders and advocates are turning to the U.N. to intervene and are calling for a moratorium on green energy projects for all U.N. entities “until the rights of Indigenous peoples are respected and recognized.”
- Indigenous leaders say they are not in opposition to renewable energy projects, but rather projects that don’t go through the due process and attend their free, prior and informed consent.
- According to the company, the wind transmission project is the largest clean energy infrastructure initiative in U.S. history, and will provide power to 3 million Americans, stretching from New Mexico to as far as California.
No protection from bottom trawling for seamount chain in northern Pacific
- A recent meeting of the intergovernmental body that manages fisheries in the North Pacific Ocean failed to confer new protections for the Emperor Seamount Chain, a massive and richly biodiverse set of underwater mountains south of the Aleutian Islands.
- Bottom trawlers plied the Emperors aggressively in the past, decimating deep-sea coral communities and fish stocks.
- A proposal by the U.S. and Canadian delegations at the meeting of the North Pacific Fisheries Commission (NPFC) would have temporarily paused the limited trawling that continues there today, but failed to reach a vote.
- The NPFC did pass a separate proposal to regulate fishing of the Pacific saury (Cololabis saira), a severely depleted silvery fish that Japanese people traditionally eat in the fall.
Mexico’s avocado industry harms monarch butterflies, will U.S. officials act? (commentary)
- Every winter, monarch butterflies from across eastern North America migrate to the mountain forests in Mexico, but those forests are threatened by the rapidly expanding avocado industry.
- Avocado production in Mexico is tied to deforestation, water hoarding and violence, and much of the resulting crop is exported to the U.S.
- Conservation groups are urging the U.S. State Department, USDA and USTR to ban imports of avocados from recently deforested lands in Mexico.

Drone cameras help scientists distinguish between drought stress & fungus in oaks
- Scientists have used remote sensing, spectroscopy and machine learning to detect sick oak trees and distinguish between drought stress and oak wilt, a fungal disease.
- A recently published study describes how researchers established a link between physiological traits of trees and light reflectance to monitor the progression of symptoms in trees afflicted by oak wilt and drought.
- They used the data to build a predictive model that can identify symptoms and detect sick oaks 12 days before visual symptoms appear.
- Oaks are vital for climate regulation and carbon sequestration; however, the trees face threats to their survival because of a fatal fungal disease as well as the worsening impacts of climate change.
Traceability is no silver bullet for reducing deforestation (commentary)
- The European Union, UK and US have passed, or are in the process of passing, legislation which places a duty on companies to prove that products they import do not come from recently deforested land.
- Businesses and governments are ramping up efforts to address emissions and deforestation in their supply chains, but the scale at which these initiatives are being implemented limits their effectiveness in tackling deforestation.
- Investments by companies and governments in farm-level traceability must be backed up by landscape approaches that address the systemic drivers of deforestation, climate change and biodiversity loss, a new op-ed argues.

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.
Florida growers eye agroecology solution to devastating citrus disease
- Virtually all of Florida’s citrus groves have been infected with citrus greening disease, also known by its Chinese name Huanglongbing, since the early 2000s.
- Despite billions of US dollars put toward rescue efforts, citrus production numbers are the lowest they have been since the Great Depression.
- Scientists from Argentina are now testing the agroecological method of push-pull pest management using an organic plant-hormone solution to lure pests away from citrus crops and toward “trap crops” instead.
- Proponents hope push-pull management, first developed in East Africa, could be part of the solution and lessen dependence on pesticides.
Enviva bankruptcy fallout ripples through biomass industry, U.S. and EU
- In March, Enviva, the world’s largest woody biomass producer for industrial energy, declared bankruptcy. That cataclysmic collapse triggered a rush of political and economic maneuvering in the U.S. (a key wood pellet producing nation), and in Europe (a primary industrial biomass energy user in converted coal plants).
- While Enviva publicly claims it will survive the bankruptcy, a whistleblower in touch with sources inside the company says it will continue failing to meet its wood pellet contract obligations, and that its production facilities — plagued by chronic systemic manufacturing problems — will continue underperforming.
- Enviva and the forestry industry appear now to be lobbying the Biden administration, hoping to tap into millions in renewable energy credits under the Inflation Reduction Act — a move environmentalists are resisting. In March, federal officials made a fact-finding trip to an Enviva facility and local communities who say the firm is a major polluter.
- Meanwhile, some EU nations are scrambling to find new sources of wood pellets to meet their sustainable energy pledges under the Paris agreement. The UK’s Drax, an Enviva pellet user (and also a major pellet producer), is positioning itself to greatly increase its pellet production in the U.S. South and maybe benefit from IRA subsidies.
New U.S. agroforestry project will pay farmers to expand ‘climate-smart’ acres
- The Nature Conservancy is leading the Expanding Agroforestry Project to provide training, planning and funds for 12,140 hectares (30,000 acres) of new agroforestry plantings in the U.S.
- Goals for the program include enrolling at least 200 farmers, with a minimum of 50 from underserved communities.
- Initial applications have surpassed expectations — 213 farmers applied in the first cycle with 93% coming from underserved populations.
- The first round of payments is set for distribution in fall 2024.
Forest and climate scientists fear Biden delay on mature forest protection
- More than 200 forest ecologists and top climate scientists, including Jim Hansen and Michael Mann, have written the Biden administration urging it to quickly move forward on the president’s commitment to protect old-growth and mature forests on federal lands.
- The scientists made an urgent plea for an immediate moratorium on logging federal forests with trees 100 years old or older, many of which remain vulnerable to logging and dozens of timber sales nationally. They also asked for the establishment of substantive federal management standards to protect those forests.
- Federally owned old-growth and mature forests play an outsized role in storing carbon, offering a vital hedge against escalating climate change.
- At stake are 112.8 million acres (45.6 million hectares) of old-growth and mature forest on federal lands, according to a 2023 U.S. Forest Service and Bureau of Land Management inventory — an area larger than California. Less than a quarter of those forests are currently protected against logging.
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.
Major meatpacker JBS misled the public about sustainability efforts, NY lawsuit claims
- New York Attorney General Letitia James filed a lawsuit against JBS USA Food Company and JBS USA Food Company Holdings for misrepresenting plans to achieve net-zero greenhouse gas emissions by 2040.
- The lawsuit cites numerous instances in which the company’s claims to the public didn’t align with what was happening behind closed doors. Its website and advertisements have boasted claims about reaching net-zero carbon emissions while company executives were making plans to grow.
- The New York attorney general said JBS Group’s greenhouse gas emissions calculations don’t include deforestation in the Amazon Rainforest, making its environmental goals “not feasible given the current scope of [its] business operations.”
U.S. natural gas expansion would surrender world to fatal warming, experts say
- The United States is planning a major expansion of its export infrastructure for liquified natural gas (LNG), a fossil fuel mostly containing methane. Public outcry in the U.S. over the risk to the global climate forced U.S. President Joe Biden to pause the LNG permitting process for reconsideration in January.
- However, the U.S. continues investing billions in new LNG infrastructure abroad. Scientists and climate activists around the globe are warning that LNG expansion renders U.S. climate commitments unreachable, locks in fossil fuel emissions for decades and could trigger catastrophic warming.
- LNG emits more than coal when exported due to massive leaks of methane into the atmosphere during oceanic transport, a preprint study has found. Another report estimates that emissions from planned U.S. LNG exports, if all 12 facilities are approved, would total 10% of the world’s current greenhouse gas emissions.
- Climate impacts around the world would be severe, scientists say. Drought in Europe, for example, is already leading to higher food and energy prices, creating conditions for poverty even in developed nations, while a tipping point in the Amazon Rainforest could lead to mass deaths due to extreme heat and humidity.
Biden’s new sanctions on Russia should include timber exports (commentary)
- U.S. President Joe Biden responded to the death of dissident Aleksei Navalny with new sanctions that target hundreds of Russian entities and individuals, but these could go further in key areas that are also good for the planet.
- Timber represents more than half of all remaining U.S. imports of Russian goods: all of Russia’s vast forests are state-owned, and some are even under control of its military. Customs data show the U.S. has imported close to $2 billion of timber from Russian companies since the war began.
- “The U.S. should immediately bar Russian timber, pulp & paper imports, as the E.U. and U.K. have already done,” a new op-ed argues.

On Kaho’olawe, new technology could restore a sacred Hawaiian island
- The small Hawaiian island of Kaho‘olawe is a sacred site for Indigenous Hawaiians, who used it for navigational training, religious ceremonies, and fishing.
- But the island has faced decades of ecological destruction due to invasive plants and animals, erosion, and bombings as a test site by the U.S. military.
- A new conservation project has successfully tested a novel method using AI-equipped camera traps and an aerial drone to collect images of invasive cats, which have destroyed the island’s seabird populations, in dangerous and difficult-to-access parts of the island.
- But funding for the work on Kaho‘olawe remains scarce, and the drone project is now on hold as local organizations seek further funding to deal with the feral cats.
After 50 years of the U.S. Endangered Species Act, we need new biodiversity protection laws (commentary)
- The U.S. Endangered Species Act marked 50 years at the end of 2023 and has achieved some notable successes in that time, like helping to keep the bald eagle from extinction, but the biodiversity crisis makes it clear that more such legislation is needed.
- “As we welcome 2024 and celebrate the strides made in biodiversity legislation, let’s draw inspiration to forge even more robust laws this new year,” a new op-ed argues.
- “In the face of the urgent biodiversity crisis, our new legislation must match the immediacy of this threat.”

Find the manatee: New AI model spots sea cows from images
- A new computer model developed by engineers at the Florida Atlantic University uses deep learning to count manatees in images captured by cameras.
- The model has been trained to identify manatees in shallow waters, and can be used to identify where they aggregate, which can, in turn, be helpful to plan conservation actions and design rules for boaters and divers.
- However, the model can’t yet distinguish between adults and calves, or between males and females, both of which are details that are vital for conservation and research purposes.
- The engineering team says it plans to continue training the model in the months ahead, while also working with biologists to get their feedback on how to improve it further.
Cornell receives $35m gift for research at nexus of wildlife and health
- Our newfound global awareness that human health, animal health and the health of the planet are inextricably linked has underscored the importance of research at the interface of wildlife and health.
- Cornell University’s College of Veterinary Medicine has announced a donation of $35 million to support its work in this burgeoning field of research.
- The Cornell K. Lisa Yang Center for Wildlife Health aims to use the funds to further its research on how disease interactions affect wildlife, domestic animal and human health, and translate its findings into policy and action to protect wildlife and wild places.
New guidebook supports U.S. tribal nations in adopting rights-of-nature laws
- A new guidebook aims to assist tribal nations across the United States in adopting legal frameworks that recognize the rights of nature.
- The growing rights-of-nature movement seeks to protect the environment by legally acknowledging its inherent right to exist and thrive independent of human use.
- The guide examines real-world challenges and pathways for passing laws and includes case studies of tribes that have enacted rights-of-nature laws through constitutions, ordinances and resolutions.
- The guide contains practical guidance on steps like surveying community perspectives, holding educational gatherings, and forming planning committees.
