Growing native plants to heal land at Indigenous owned nursery in British Columbia
- The Ktunaxa First Nation owned Nupqu Native Plant Nursery in south-eastern British Columbia propagates over 60 native plant species, with a focus on locally-collected seed.
- The nursery grows 700,000 seedlings on site, and through five partner nurseries, supplies 2.5 million seedlings a year for restoration, mostly within Ktunaxa territory in Canada.
- Over the past five years of operation, the nursery has built up a wealth of knowledge on how to propagate many tricky species.
- Nupqu is now working with partners to build up an Indigenous-led native plant nursery industry in British Columbia.

Doug McConnell, interpreter of Northern California, has died, aged 80
- Doug McConnell, who died on January 13, 2026, spent decades using local television to help Northern Californians see their landscapes as shared civic assets rather than scenery, making conservation legible, practical, and personal.
- Best known for Bay Area Backroads and OpenRoad with Doug McConnell, he treated parks, trails, and open space as the result of human choices and public effort, consistently foregrounding the people and institutions that protected them.
- A storyteller shaped by a lifelong love of California’s diversity, he combined curiosity about place with a clear-eyed understanding of governance, showing how history, policy, and persistence shape the land people inherit.
- At a time of mounting environmental strain, McConnell resisted despair by staying close to the work itself, drawing energy from those quietly maintaining and restoring the natural world, and inviting viewers to join them by paying attention.

Study tracks fishing boats to see how heat waves affect fish distribution
- A new study suggests an early way to detect ecological shifts during marine heat waves: Use fishing vessel tracking data.
- The study found that tracking data could provide early detection of extreme northward and inshore shifts in albacore tuna and Pacific bluefin tuna distribution in response to heat waves and showed when such shifts weren’t happening despite high sea surface temperatures.
- The authors position fishers as “apex predators” and build on research that finds that predators are good ecosystem sentinels.

An inventory of life in California
- California is one of the world’s biodiversity hotspots, yet much of its life—especially insects and fungi—remains undocumented, even in a state rich in scientific institutions.
- The California All-Taxa Biodiversity Inventory (CalATBI) is working to build a verifiable, statewide record of life, combining fieldwork, DNA analysis, and museum collections.
- By focusing on evidence that can be revisited and tested over time, the effort provides a baseline for understanding ecological change rather than prescribing solutions.
- Mongabay’s reporting follows how this foundational work underpins later decisions about protection, restoration, and management—showing why counting still matters.

Guatemala’s eco defenders reel from surge in killings and persecution
- In 2023, there were four recorded killings of environmental defenders in connection to their work; in 2024, this figure shot up to at least 20, according to advocacy group Global Witness.
- An ongoing political crisis, persistent criminalization, and the spread of organized crime have all fed the rise in violence against Indigenous and campesino communities and defenders.
- This is happening despite a change of government, led by President Bernardo Arévalo, whose movement was backed by Indigenous communities.
- Land grabbing, mass arrest warrants and judicial persecution are increasingly common, together with the use of force, say human rights defenders and activists.

Up close with Mexico’s fish-eating bats: Interview with researcher José Juan Flores Martínez
- The fish-eating bat (Myotis vivesi) catches fish and crustaceans thanks to its long legs, hook-shaped claws and waterproof fur.
- The species is found only on islands in Mexico’s Gulf of California; it’s considered endangered under Mexican law.
- Invasive species such as cats and rats threaten the bats.
- Researcher José Juan Flores Martínez has been studying fish-eating bats for more than 25 years, and discusses his fascination with the species and the threats it faces.

How are California’s birds faring amid ever more frequent wildfires?
- Long-term research in California shows that many bird populations increase after wildfires and can remain more abundant in burned areas for decades, especially following moderate fires.
- Although some bird species are adapted to fire and benefit from low to moderately severe blazes, megafires in California are becoming more frequent.
- Megafires, scientists say, are unlikely to benefit most bird species and harm those that depend on old-growth forests.
- Wildfire smoke poses a serious threat to birds’ health, with evidence linking heavy exposure to particulate matter in smoke to reduced activity, weight loss and, possibly, increased mortality.

Investor Dick Bradshaw took a long view of conservation
- Conservation philanthropy often rewards urgency.
- Dick Bradshaw took a longer view, funding research, fellowships, and land protection with an emphasis on permanence rather than campaigns.
- His support helped steady conservation science in Canada by investing in people and institutions built to last.
- Bradshaw died in December 2025.

A small preserve leads a big effort to save native plants in the Bahamas
- The Leon Levy Native Plant Preserve is a 12-hectare (30-acre) estate on Eleuthera, an island in the Bahamas, dedicated to conserving and educating people about the island-nation’s native plants.
- Since 2009, resident botanist Ethan Freid has led a local restoration effort prioritizing native plants of the Bahamas’ subtropical dry forest ecosystem.
- The Levy preserve also offers a summer internship for university students interested in environmental science and biology, which teaches them about native plant taxonomy — filling a generational knowledge gap.
- Though small in scale, the project provides a haven for the Bahamas’ native plants; has a herbarium of plant specimens for research; and manages an online digital database of Caribbean plant species.

Andy Mahler, advocate for public forests in America
- Forest conservation in the eastern United States often depended on persistence rather than decisive victories, shaped by slow regulatory processes and fragmented governance that rewarded those willing to keep showing up after attention faded.
- Out of this context grew a form of grassroots activism grounded in local knowledge and personal trust, skeptical of hierarchy and resistant to the idea that extractive outcomes were inevitable or natural.
- Andy Mahler embodied that approach through decades of work protecting public forests, most notably as a central figure in Heartwood, a decentralized network built on sustained relationships rather than efficiency or scale.
- He favored patient, place-based engagement over professionalized advocacy, believing that lasting protection came from continued involvement and shared responsibility rather than fixed outcomes or abstract measures.

In California’s redwoods, scientists rebuild lost ecosystems high up in the canopy
- Roughly 95% of California’s old-growth redwood forests have been logged at least once, leaving mostly young trees and making the overall ecosystem less diverse.
- Fern mats — spongy masses of leather-leaf ferns and decomposed plant matter that build up high in the canopy — are an important part of that system, providing critical habitat for plants and animals in California’s redwood forests.
- Now, a pilot project is trying to restore fern mats to the canopies of particularly robust redwood trees.
- Scientists are finding that manually planting fern mats is also an effective buffer in a warming climate: they mitigate forest temperatures for salmon, birds and a host of other animals.

How ‘Adventure Scientists’ provide pioneering data for conservation
Gregg Treinish didn’t start out as an outdoor enthusiast, but found solace and purpose in nature during his youth. After years of enjoying the outdoors, he was left feeling a need to give something back to the world. He found fulfillment by using his passion for outdoor adventures to gather critical data that researchers need […]
Century-old corals reveal the Pacific Northwest is acidifying faster than expected
- When compared with historical samples, corals show that the Salish Sea and California Current System are acidifying faster than anticipated because of greenhouse gas emissions. Models indicate that at this rate, carbon dioxide levels in the oceans will continue rising faster than concentrations in the atmosphere.
- Increasingly acidic seas pose growing risks to sensitive marine life, from clams and oysters to any organism with a spine, as well as economically important fisheries and the communities that depend on them.
- British marine ecologist Stephen Widdicombe calls the threat existential. Our continued failure to cut emissions can only lead to “a world where uncontrolled climate change including ocean acidification leaves us with an ocean that is less productive, less diverse and less able to provide humans with the wealth of services that we currently all benefit from,” he said.

Statewide survey aims to put California’s fungi on the conservation map
- A state-funded survey has sampled and collected fungi species from across California, identifying hundreds of new-to-science species.
- It’s part of a statewide effort to protect biodiversity, which has yielded thousands of specimens and is the first of its kind in North America.
- Fungi are often neglected compared to the attention given to plants and animals, yet they play an important role in maintaining ecological health by supporting plant growth and storing carbon.
- Understanding fungi’s role in nature has implications for conservation and for forest restoration as wildfires grow larger and more frequent. Other researchers in California are working on putting fungi to use cleaning up polluted areas.

Zombie urchins & the Blob: California sea otters face new threats & ecosystem shifts
- Southern sea otters living along California’s coast are struggling in warmer seas, with new threats and changing food sources. They, like the other two sea otter subspecies, are classified as endangered.
- Human disturbance, especially in Monterey Bay, is limiting the otters’ ability to forage, impacting mother and pup survival. Meanwhile, sharks are expanding their range as waters warm, with increasing attacks on otters.
- Following a mass die-off of the purple sea urchin’s predators — sunflower and ochre sea stars — the urchins decimated kelp forests, which are important sea otter habitat. Mussels then proliferated, replacing urchins in the otter’s diet, and invasive green crabs are now also on the menu.
- Otter numbers seem to be dropping, but a definitive census has not been conducted since 2019. A new population estimate based on data and statistical modeling is due to be released soon.

New study splits giraffe experts on future wild captures for zoos
- Hybridization of captive giraffes in North American zoos may impact conservation, given the recent scientific consensus that giraffes are four distinct species, not a single species as previously thought.
- The study recommends international collaboration in future breeding programs, in which giraffes would be captured from the wild in Africa and moved to North American zoos to essentially start a captive-breeding program of genetically pure individuals.
- But giraffe conservationists say the study’s recommendations would be detrimental to wild conservation, arguing that capturing giraffes for zoos would deplete wild populations.

Earth’s freshwater fish face harsh new climate challenges, researchers warn
- Climate change is rapidly altering freshwater ecosystems — raising temperatures, altering flood pulses and oxygen levels — and driving complex, region-specific changes in how fish grow, migrate and survive.
- Long-term U.S. data show sharp declines in cold-water fish as streams and lakes warm, while warm-water species gain only slightly. Some cold-adapted species are now disappearing as deep waters cease being a cold refuge.
- From Africa to the Arctic, impacts are emerging, including stronger lake stratification, declining fisheries and rivers turning orange as thawing permafrost releases toxic metals. Declining freshwater fisheries increasingly put food security at risk, especially affecting diets and health in traditional and Indigenous communities.
- Scientists say management and conservation techniques rooted in past conditions no longer work. New approaches must anticipate shifting baselines as climate change rapidly accelerates.

Mexico is inflating its climate spending by billions of dollars. Here’s how.
- Mexican President Claudia Sheinbaum took office last year touting her climate science background, yet continues to neglect renewable energy and conservation while subsidizing state-owned oil company Pemex.
- Funds her government earmarked for climate change and a renewable energy transition are actually going to infrastructure, oil and gas, and other projects unrelated to the environment, a review of the 2026 budget shows.
- In one case, more than $40 million for a train line is counted twice but only spent once, misrepresenting how much money the government is dedicating to the environment.

Choosing coexistence over conflict: How some California ranchers are adapting to wolves
- California’s expanding gray wolf numbers — a conservation success for an endangered species — have worried ranchers in recent years as wolf-related livestock kills mount.
- Some ranchers are adapting to the changing landscape, using short-term nonlethal deterrents, some of which are funded by a state compensation program.
- A few ranchers are exploring long-term approaches, such as changing their ranching practices and training their cattle to keep them safe from wolves.
- While change is hard, ranchers acknowledge that learning to live with the new predator is the only way forward, and it pays to find ways to do so.

Boom in burning waste for fuel could put human health and environment at risk
- Refuse-derived fuel (RDF) — conglomerated waste often composed of up to 50% plastic — is being burned globally in waste-to-energy incinerators, cement kilns, paper mills, and by other industries.
- Proponents say RDF reduces fossil fuel use and produces cleaner energy, while diverting waste from landfills.
- Critics say a lack of monitoring often hides RDF’s true environmental and human health footprint, and that when burned alongside fossil fuels, the technology can significantly worsen pollution. Health issues potentially connected to RDF contaminants range from cancer to hormone disruption.
- That’s a major concern as RDF ramps up, with countries in the Global South especially starting to use and dispose of waste in this way. Burning RDF and the incineration of plastic waste has been linked to greenhouse gas emissions and also extremely toxic pollutants such as dioxins.

The last of the Vaquita Porpoise (cartoon)
With an estimated less than 10 individuals alive, the vaquita porpoise of the Gulf of California is on the brink of extinction. Entanglement in gill nets used for fishing totoaba fish in the Sea of Cortez has been the prime threat to vaquitas, and while bans are already in place, the lack of enforcement leaves […]
‘Silent epidemic of chemical pollution’ demands radical regulatory redo, say scientists
- An international team of 43 scientists has called for a “paradigm shift” in toxicology and chemical regulation globally after having found severe lapses in current regulatory systems for evaluating the safety of pesticides and plastics derived from petrochemical byproducts.
- The researchers note that the full commercial formulations of common petrochemical-based pesticides and plasticizers have never been subjected to long-term tests on mammals. Only the active ingredients declared by chemical companies have been assessed for human health risks, while other ingredients have not.
- The scientists found that synthesized pesticides and plasticizers contain petroleum-based waste and heavy metals such as arsenic that can make them “at least 1,000 times more toxic” than the active ingredients alone, posing chronic disease and health threats, especially to children — claims that the chemical industry denies.
- Researchers urge lowering the admissible daily intake, or toxicity threshold, for already approved chemical compounds; long-term testing on the full formulations of new pesticides and new plasticizers; and requiring all toxicological data and experimental protocols for approved commercial compounds be made public.

Jean Beasley, who turned her young daughter’s dying wish into a mission to save sea turtles, has died
- After the death of her daughter Karen in 1991 and her dying wish to “do something good for sea turtles,” Jean Beasley committed herself to sea turtle conservation on Topsail Island, North Carolina.
- She founded the state’s first sea turtle rehabilitation center, beginning in a cramped 900-square-foot space and growing it into a respected 13,000-square-foot hospital and public education facility in Surf City.
- Beasley valued both direct action and education, believing that saving one turtle mattered but inspiring others—especially children—to care about the ocean could save many more.
- Her decades of work helped protect more than 3,000 nests and rehabilitate at least 1,600 turtles, while also motivating future conservationists and proving that a daughter’s dying wish could become a movement of hope.

First state-authorized killings mark escalation in California’s management of wolves
- California’s wildlife department killed four gray wolves in the Sierra Valley in late October, in a dramatic escalation of tactics to address growing predation of cattle by the canids and despite protection under state and federal endangered species laws.
- The department says the wolves killed at least 88 cattle in Sierra and Plumas counties and continued to target livestock despite months of nonlethal deterrents deployed to drive them away.
- The state employed lethal action despite its compensation program, which pays ranchers for cattle killed by wolves, and additional federal subsidies paid to the livestock industry at large.
- The state wildlife agency confirmed a new pack –– the Grizzly pack–– earlier this week with two adults and a pup. Though the state’s wolf population remains small and vulnerable, ranchers are increasingly concerned about livestock deaths.

Are wolves scared of us?
The “big bad wolf,” as portrayed in popular culture, still has a healthy fear of humans, a new study reveals. As wolves return to parts of their historical ranges in Europe and North America, there’s growing concern that the predators are becoming less fearful of people. But a recent study from Poland shows that wolves […]
It’s ‘whack-a-mole’: Alarming rise in pet trade fuels wildlife trafficking into California
- California has become a wildlife trafficking hotspot in the U.S., with a notable spike in live animals smuggled across the southern border to be sold as pets, from monkeys and exotic birds to venomous snakes.
- The state has three high-traffic border crossings with Mexico and millions of tons of cargo shipped through some of the nation’s busiest airports and seaports. With limited staff, resource-strapped agencies face serious challenges in policing the illegal import of protected plants and animals into California.
- Poachers also target California’s native plants and reptiles, threatening local species. Meanwhile, some imported animals get loose and become invasive species that destroy ecosystems or may carry diseases, creating public health risks.
- As traffickers exploit new technologies and follow market demand for different animals, enforcement officials struggle to control the influx of illegally traded species.

‘Forever chemical’ contamination could undermine sea otters’ fragile recovery in Canada
- Sea otters living along the coastline of Canada’s British Columbia province are exposed — and absorb — forever chemicals, a new study shows.
- Each of the 11 sea otters tested carried residues PFAS chemicals, with concentrations higher for those living near dense human populations or shipping lanes.
- The Canadian government released an assessment earlier this year recommending that PFAS be classed as toxic and is moving toward adopting tighter rules for these chemicals. Environmentalists support the initiative.

Inside California’s race to document its insects: A conversation with Chris Grinter
- Christopher C. Grinter, Senior Collection Manager of Entomology at the California Academy of Sciences, discussed his work documenting California’s insect diversity through the California All-Taxa Biodiversity Inventory (CalATBI).
- He described how DNA barcoding and voucher specimens together form a lasting record of life, helping scientists track species and environmental change across the state.
- Grinter reflected on both the urgency of discovery amid biodiversity loss and the promise of new technologies and collaborations that make large-scale insect research possible.
- He spoke with Mongabay founder and CEO Rhett Ayers Butler in October 2025.

Scientists slam Canada-US proposal to lower trade protections for peregrine falcons
- Peregrine falcons, the world’s fastest and most widespread raptors, recovered spectacularly after pesticides that nearly drove them to extinction were banned and captive-bred birds were rewilded, making the effort a remarkable conservation success story.
- Although the species is no longer endangered, international commercial trade in this bird, coveted by falconers, is banned for wild-caught specimens and highly regulated for captive-bred ones. Canada and the U.S. propose loosening those restrictions, a proposal that will be voted on at the upcoming meeting of CITES, the global wildlife trade treaty.
- Some raptor scientists have concerns. The Canada-U.S. downlisting proposal includes population estimates of just a few subspecies; many others are understudied. Some populations have declined in recent years and illegal trade continues.
- Until there are safeguards against unsustainable trade and accurate assessments for all subspecies, conservationists say lowering protections could undo the efforts that have brought this bird back from the brink.

Trade in marine fish for aquariums includes threatened species, lacks oversight: Study
- A new study of major U.S.-based online retailers of marine fish bound for aquariums found that nearly 90% of traded species are sourced exclusively from the wild, including a number of threatened species, and that the trade is poorly tracked.
- The study raises concerns about the ecological impact of the trade on marine ecosystems, including around coral reefs, in countries such as Indonesia and the Philippines, where the fish are caught.
- Experts called for more work to develop sustainable fisheries and aquaculture in coastal communities in the Global South, and for building consumer awareness and establishing eco-certification schemes.

From waffle gardens to terraces, Indigenous groups revive farming heritage in America’s deserts
- Native American farmers in the southwestern United States have long deployed weather-adaptive techniques to grow crops such as corn and beans in high-desert environments only occasionally visited by rain.
- In recent years, a variety of tribal groups have arisen to train the next generation of Native American farmers as a means of promoting cultural identity and improving self-sufficiency, health and well-being while using farming strategies that have worked for centuries on arid lands.
- The techniques range from hillside terracing and “waffle” gardening, to water conservation and leveraging microclimates on a piece of land.
- During Native American Heritage Month in November, Mongabay spoke with the leaders of these groups about their traditional farming techniques and how they can be replicated in increasingly dry regions around the world.

Scientists & nuns unite to save Mexico’s rare achoque salamanders
For the last 20 years, Dominican nuns in a Mexican monastery have cared for the largest known captive population of the critically endangered achoque salamander. Now scientists from Chester Zoo in the U.K. are collaborating with the sisters and Mexican conservationists to test a microchipping method that they hope will help them monitor the species’ […]
Massive turtle bust in Mexico reveals ‘Wild West’ of wildlife trafficking
- A sting by Mexican authorities in September uncovered more than 2,300 live, wild-caught freshwater turtles and other valuable wildlife products. Three men were arrested and charged with wildlife crimes.
- Vallarta mud turtles, the world’s smallest and the most imperiled in the Western Hemisphere, were among the eight species seized by authorities. All are in high demand as pets, and were headed for the U.S. and Asia.
- Smuggled under horrific conditions, nearly half of the turtles seized in this raid died; the rest are being cared for at Guadalajara Zoo.
- This operation highlights rampant turtle smuggling in Mexico, home to the second-most turtle species on the planet. Conservationists urge officials to tighten law enforcement and intelligence gathering to combat trafficking that threatens the survival of the country’s wildlife.

Photos: Drones help First Nations track down cold-water havens for salmon amid warming
- Indigenous fisheries association and river guardians, representing several Mi’kmaq nations in eastern Canada, have launched a drone-based thermal-mapping campaign to locate and protect cold-water refuges vital for threatened Atlantic salmon.
- Warming temperatures are pushing the Atlantic salmon beyond their ideal thermal tolerance, compounding existing pressures on the species, such as overfishing.
- Warming waters and declining river flows during droughts are impacting both the fisheries and the cultural lifeblood of Mi’kmaq society.
- Indigenous river guardians hope the project will pre-emptively shield cool-water habitats before key spawning and migration corridors become unviable.

Iguanas on Mexico’s Clarion Island likely native, not introduced by people: Study
Researchers have long speculated that humans introduced spiny-tailed iguanas to Mexico’s remote Clarion Island about 50 years ago. However, a recent study suggests the Clarion iguanas are likely native to the island, arriving long before human colonization of the Americas. Clarion Island is the westernmost and oldest of a small group of islands in Mexico’s […]
What Central Park’s Squirrel Census says about conservation tech: Interview with Okala’s Robin Whytock
- At the end of New York Climate Week this year, ecologist Robin Whytock spent a few hours in Central Park counting squirrels.
- His mission was to prove how scalable tech solutions could help make biodiversity monitoring easier and more efficient.
- Whytock, who runs AI-powered nature monitoring platform Okala, said that while data-gathering tools have become easily accessible, analyzing massive amounts of biodiversity data still remains a challenge.

Turning outdoor exploration into environmental discovery: Gregg Treinish and the rise of Adventure Scientists
- Gregg Treinish, founder of Adventure Scientists, has built a global network of trained volunteers who collect high-quality environmental data for researchers, agencies, and conservationists. His organization bridges the worlds of outdoor adventure and scientific rigor.
- From microplastics and illegal timber to biodiversity mapping, Adventure Scientists’ projects have filled crucial data gaps and influenced policy, research, and corporate practices around the world.
- In California, Treinish’s team is partnering with the California All-Taxa Biodiversity Inventory (CalATBI) to help catalog the state’s immense diversity through thousands of insect and soil eDNA samples collected by volunteers.
- Treinish spoke with Mongabay founder and CEO Rhett Ayers Butler in October 2025 about scaling trust-based citizen science, the value of human observation in nature, and why adventure remains a powerful gateway to environmental action.

Night dives reveal hidden alliances between young fish and larval anemones
- A new study, drawing on nighttime underwater photography, documented previously unknown “symbiotic associations” between juvenile fish and larval anemones, with some fish staying close to the anemones, and others carrying them around.
- The study suggests the fish may gain protection from predators by associating with the toxic anemones, while the anemones could benefit from being transported by the fish to new parts of the ocean.
- An outside expert also proposed that anemones might receive additional benefits, such as nutrients from the fish’s excretions or from food scraps left behind.
- All of the experts emphasized that more research is needed to fully understand the dynamics of these relationships.

California’s grand insect census
- Austin Baker and his team at the Natural History Museum of Los Angeles County are leading an ambitious effort to DNA-barcode every insect species in California as part of the statewide CalATBI initiative to “discover it all, protect it forever.”
- The project combines traditional specimen collection with modern genetic sequencing to build a comprehensive biodiversity library, revealing surprising hotspots of insect life—from foggy coasts to the species-rich Mojave Desert.
- By creating a genetic baseline of California’s insect diversity, the team hopes to track future ecological change, inform conservation priorities, and preserve the record of countless species that might otherwise vanish unnoticed.
- Baker was interviewed by Mongabay’s Rhett Ayers Butler in October 2025.

Drax pellet mill wins appeal to raise pollution limits in small Mississippi town
- Industrial forest biomass wood pellet mills now dot rural areas around the globe, with plants concentrated in the U.S. Southeast, and other major facilities found in Canada, the EU, Russia, Vietnam, Indonesia and elsewhere. The EU, Japan and South Korea burn most of the wood pellets currently being produced.
- Pellet mills have increasingly come under fire from rural communities who accuse large-scale manufacturers like the U.K.’s Drax and Enviva in the U.S. of air pollution, dust and noise violations, which harm residents’ health and quality of life. A 2023 study found that pellet mills in the U.S. Southeast release 55 hazardous pollutants.
- In a rare victory last April, the town of Gloster, Mississippi, won a major pollution permitting battle against Drax’s Amite BioEnergy pellet mill — one of the largest in the world. But at an October appeal meeting, the Mississippi Department of Environment Quality reversed itself, giving Drax permission to pollute more today than previously.
- The Drax plant has been fined more than $2.75 million since 2016 for exceeding toxic emissions limits. Drax says it has invested millions in pollution mitigation technology to prevent future pollution. A law firm representing Gloster citizens is filing a federal lawsuit alleging Drax has been violating the Clean Air Act since opening the Gloster plant in 2015.

Mexico adopts protections for Atlantic sharks
Mexico recently adopted national regulations protecting several threatened shark species in the Atlantic from being caught or retained as bycatch. Shark conservationists welcome the protections but say they are long overdue, coming years after the country’s commitments to a multilateral fishery regulator. Mexican fisheries catch a significant number of various shark species in the Atlantic […]
Chris Allnutt, negotiator who helped protect the Great Bear Rainforest, died on September 21st
- Chris Allnutt, a veteran labor negotiator, brought the same patience and moral clarity that defined his union leadership to the campaign that protected British Columbia’s Great Bear Rainforest.
- As head of the Hospital Employees’ Union in the 1990s, he led thousands of mostly immigrant women through an illegal strike against government privatization—losing his job but later vindicated by a Supreme Court ruling.
- Afterward, he became project director of the Rainforest Solutions Project, guiding environmental groups, industry, governments, and First Nations toward the landmark 2016 agreement safeguarding 85% of the rainforest’s old growth.
- Friends remembered him as calm, principled, and quietly forceful—a man who believed fairness could be negotiated, that empathy was strength, and that even in the hardest fights, listening was a radical act.

Radar study shows when offshore turbines pose greatest risks to migrating birds
- A new study looks at bird migration patterns over open ocean in an attempt to assess how much risk offshore wind turbines and other marine infrastructure might pose to them.
- The authors used radar data from U.S. coastal weather stations to find that hundreds of millions of birds migrate over tight windows of time in the spring and fall while flying at slightly lower elevations on average than over land.
- This puts a proportion of them at risk of being killed by wind turbines, but that risk could be mitigated with dynamic management that accounts for their patterns, according to the study.
- The Trump administration, in office since January, says it doesn’t support offshore wind development, but the research has long-term implications and could be used more immediately for mitigating the impact of offshore oil and gas projects.

Booming sea otters and fading shellfish spark values clash in Alaska
- In Alaska, a state brimming with iconic wildlife — from grizzly bears to king salmon, humpback whales to harbor seals — the charismatic, densely coated sea otter stands out as perhaps the state’s most hotly debated, controversial species.
- Sea otters were nearly hunted into extinction a century ago for their luxurious pelts. But they have been surging in population in the Gulf of Alaska, bringing both benefits to nearshore ecosystems and drawbacks to the shellfish economy (due to the otters’ voracious caloric needs).
- Described by commercial shellfish harvesters and Native Alaskans as pillagers of clams and crabs, sea otters are seen by many marine biologists as having positive impacts on kelp forests — important for biodiversity and carbon storage. Scientists stress that shellfish declines are complex, with sea otters being just one among multiple causes.
- Native Alaskans are the only people given free rein to hunt sea otters. But long-standing federal regulations stipulating who qualifies as Native Alaskan make it illegal for most to manage their own waters. Tribes are fighting for regulatory changes that would enable them to hunt and help balance booming sea otter populations.

As wolves roam California, livestock losses remain low, yet ranchers’ fears grow
- In California, as wolf numbers grow — a remarkable return after a century — livestock producers are increasingly worried as these predators occasionally take down cattle.
- Gray wolves are an endangered species, protected under both federal and state laws, complicating the balance between conservation and economic losses, though livestock kills remain low.
- California introduced a compensation program that pays ranchers for direct and indirect losses from wolves as a way to mitigate conflicts, but ranchers say this program isn’t scalable with expanding wolf numbers. The livestock industry also receives substantial taxpayer-funded subsidies.
- Wolves were extirpated from California a century ago, so ranchers haven’t lived alongside them for generations and are pushing to remove all protections for the species. Conservationists argue coexistence is the only way forward.

Drone surveys offer early warnings on whale health and survival
- Scientists have deployed drones and are using photogrammetry to determine how climate change is impacting the health of whale populations.
- By collecting the measurements of whales, scientists are able to track how environmental factors impact the growth and reproduction of right whales off the coast of New England and orcas in Alaska.
- Using the data, they found that a marine heat wave in 2013 reversed the revival of the population in Alaska that had plummeted after the Exxon Valdez oil spill in 1989; they also noticed that the whales didn’t grow as much as they should have.
- The method also enabled scientists to detect pregnant whales well in advance, allowing them to monitor if the pregnancy was successful or not.

Warmer climate could slash threatened whitebark pine territory within decades: Study
- A study published Sept. 2 in the journal Environmental Research Letters forecasts an 80% reduction in the area with suitable climates for whitebark pine by the mid-21st century.
- This long-lived, high-elevation tree plays a critical role in mountain ecosystems in western North America, providing food for wildlife and regulating water supplies.
- But a disease-causing fungus has ravaged whitebark and other pine species, compounded by other threats, such as wildfire, mountain pine beetles and climate change.
- The research, which identifies areas that will likely be climatically suitable for whitebark pine in the future, could help guide restoration efforts to save the species.

Death toll from torrential rains in Mexico rises to 64 as search operations expand
POZA RICA, Mexico (AP) — The death toll from last week’s torrential rains in Mexico jumped to 64 on Monday, as searches expanded to communities previously cut off by landslides. Another 65 people were missing following the heavy rainfall in central and southeastern Mexico that caused rivers to top their banks, Civil Defense Coordinator Laura Velázquez Alzúa said […]
Uphill battle to save California’s endangered mountain yellow-legged frog
- Conservation organizations released 350 mountain yellow-legged frogs earlier this year, marking another step in an intensive, long-running reintroduction project for this highly endangered species in Southern California.
- Once abundant across its range, populations have declined drastically because of invasive fish species, climate change impacts, and the deadly chytrid fungus that is wiping out amphibians worldwide.
- Conservationists are testing out new ways to boost survival rates of released frogs. Though it’s hoped the species may one day recover, today they are locked in a fight against extinction.

Will California’s marine mammal conservation success come undone?
- With protection, many of California’s marine mammals — including whales, sea lions and seals — have made remarkable recoveries over the last half-century since bipartisan passage of the U.S. Marine Mammal Protection Act.
- However, climate-linked changes have now pushed the gray whale population into a state of collapse.
- Despite comebacks, marine mammals face a plethora of threats from pathogens, pollutants — including oil and plastic — disappearing food and more.
- In California, people and institutions are fighting for marine mammals and ocean biodiversity, but federal protections could be substantially weakened if proposed amendments to the Act move ahead.

Wildfire smoke could kill 71,000 people per year in the US by 2050, study warns
- A new Nature study projects wildfire smoke will cause 71,000 excess deaths annually in the U.S. by 2050, representing $608 billion in damages that exceed all other estimated climate costs combined.
- Researchers linked climate conditions to fire emissions, smoke concentrations and mortality using historical death records and satellite data, finding that approximately 41,000 annual deaths already occur from wildfire smoke.
- More than half of projected deaths occur in Eastern U.S. states due to population density and long-range smoke transport, with health impacts lasting up to three years after exposure.
- Even if nations dramatically cut emissions, more than 60,000 Americans will still likely die annually from wildfire smoke by 2050 because Earth’s climate system takes decades to respond to changes, making adaptation strategies like air filters and forest management critical despite their limitations.

Women in Mexico step up to protect the island farms traditionally inherited by men
- In Mexico, traditionally women did not inherit chinampas, island farms first built by the Aztecs thousands of years ago. The farming on such islands, which sit in Mexico City, has also traditionally been done by men.
- Today, women are buying up chinampas and doing sustainable farming, along the way helping to maintain ecosystems that are threatened by urbanization and water pollution.
- This wetland system is the last remnant of what was once the great Tenochtitlan, the capital of the Aztec Empire built on the lakes that once filled the Valley of Mexico.
- What remains of Xochimilco today represents only 3% of the original extension of those lakes. However, the chinampas are still key to the stability of the city.

Northeast Pacific endures fourth-largest marine heat wave on record
The Northeast Pacific ocean, off the U.S. West Coast, is experiencing its fourth-largest marine heat wave since record-keeping began in 1982. “The extent of the current Pacific marine heatwave should be surprising … but unfortunately, record breaking heat is our new norm,” Chris Free, a marine scientist at the University of California, Santa Barbara, told […]
Grue jay or Bleen jay? Researchers confirm hybrid between blue and green jays
Researchers have for the first time confirmed that a blue jay and a green jay have mated in the wild to produce a rare hybrid with mixed features. Spotted by a birder named Donna in her backyard in San Antonio in the U.S. state of Texas, this hybrid may have resulted from the two jay […]
From Chile to Greece, ‘ghost gear’ from fish farms haunts the seas
- Studies and NGOs have documented lost or abandoned gear from open-net aquaculture operations in coastal areas across cold and temperate latitudes, where fish farming in the sea expanded rapidly in the 1980s and ’90s.
- In Chile, Greece and Canada, for example, observers have reported finding disused buoys, sections of rusting platforms, expanded polystyrene, net cages and other debris washed up on shorelines, or sunk in the water.
- Guidelines published by the Global Ghost Gear Initiative (GGGI), a worldwide alliance of groups seeking solutions to fishing gear pollution, say neglected or mismanaged aquaculture gear can disperse in the environment and break down into debris of various sizes, posing risks such as entrapping marine life, damaging habitats or contributing to microplastic pollution.
- Some industry groups say current regulations and practices suffice to prevent ongoing pollution and they are working to resolve legacy contamination.

Alaskan rivers turn orange as permafrost thaws, threatening fish and communities
- A new study found that 75 streams in Alaska’s Brooks Range have turned orange due to thawing permafrost, which releases metals like iron, aluminum and cadmium that exceed U.S. Environmental Protection Agency safety thresholds for aquatic life.
- The contamination threatens fish populations, with aluminum concentrations at one location reaching nearly five times the safe limit, and the study suggests this may help explain recent crashes in chum salmon returns that Indigenous communities depend on for food and income.
- The pollution flows hundreds of miles downstream to coastal communities like Kivalina, where residents who rely on traditional fishing face threats to food security as some tributaries of rivers like the Wulik have begun turning orange.
- Scientists warn that this climate change impact is irreversible and spreading across the Arctic, with no cleanup options, as these remote watersheds contain hundreds of contamination sources.

Ocean acidification threatens planetary health: Interview with Johan Rockström
- The newly published 2025 Planetary Health Check report confirms transgression of the ocean acidification planetary boundary — the seventh Earth system threshold crossed, putting a “safe operating space for humanity” at risk. Oceans act as a key climate stabilizer, resilience builder and Earth life-support system.
- Marking the launch of the 2025 Planetary Health Check, Mongabay speaks with report co-author and renowned Earth system scientist Johan Rockström about how the transgression of planetary boundaries is eroding environmental justice — the right of every human being to life on a stable, healthy planet.
- Rockström, who led the international team of scientists who originated the 2009 planetary boundary framework, also speaks about the failure to achieve a U.N. plastics treaty in August and the challenge of accomplishing planetwide sustainability in a time of widespread armed conflict and political instability.
- He likewise emphasizes the need to bring the U.S. back to the negotiating table at COP30, the U.N. climate summit scheduled for November, in Belém, Brazil, and addresses the importance of inserting the planetary boundaries framework into those talks.

When does beaver reintroduction make sense?
- California has recently relocated beavers from spots where they were causing problems, like flooding, to tribal lands in Northern and Southern California.
- Many advocates say that relocating beavers to areas where they once existed brings back “ecosystem engineering” benefits to the landscapes they live in.
- But experts also caution that while beavers can help with fire resilience and improve water quality, they are only part of broader solutions to climate change and watershed restoration.
- Beaver advocates also note that learning to coexist peacefully with beavers is critical, both for the recovery of the species and for the ecosystem services they provide.

Timing, not traits, helps California’s jewelflowers adapt to diverse landscapes
- California’s native jewelflowers, a group of plants that belong to the mustard family, grow in widely diverse landscapes and microclimates across the state. But until now, scientists didn’t understand what allowed their wide distribution.
- To understand this, researchers analyzed information from nearly 2,000 specimens; dug into climate and geological databases; and amassed field observations to understand the climatic conditions that 14 species of jewelflowers need to grow and reproduce.
- Their study found that, despite living in different landscapes, from desert to valleys and mountains, jewelflowers prefer hotter and drier climates, timing their sprouting and flowering accordingly. Even those species growing in colder regions adjust their life cycle to flower later in the summer and seek drought-prone soils.
- The research shows how plants distributed across vast geographies may require specific microclimates and habitats to survive, which are potentially at risk in a warming world.

The return of the axolotl (cartoon)
Axolotls may enjoy celebrity status among pet owners, but their wild populations have been dealt huge blows by habitat loss, water pollution, invasive species and the pet trade. Now, the success of reintroduction programs in their native ranges in Mexico — where they have tremendous cultural significance — brings new hope for their comeback.
