After historic 2024 coral bleaching, hope remains for Mesoamerican Reef
- The Mesoamerican Reef, the longest barrier reef in the Western Hemisphere, stretches 1,000 kilometers (620 miles) along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras.
- The latest instalment of the Mesoamerican Reef Report Card, a periodic health assessment, finds that in 2024, the worst coral bleaching event on record reduced the reef’s coral cover.
- Although the overall health of the Mesoamerican Reef remains “poor,” according to the report, its health actually improved for the first time in five years.
- The report attributes this positive development to an increase in fish populations due to effective enforcement of fisheries rules by regional authorities.

That Cuban rodent species you never knew about? Turns out it’s two species
- New genetic research of museum specimens has found that the large rodents known as hutias on Cuba are two distinct species, not one as previously thought.
- ‘Capromys pilorides’ inhabits the eastern part of the island, and ‘Capromys geayi’ is found in the west, split by nearly 2 million years of evolution, likely due to a once-deep water channel that also divided Cuba.
- Scientists say the conservation status of both these is least concern, but threats such as deforestation, poaching and invasive predators remain.
- The eastern species may be a candidate for rewilding in the Cayman Islands, whose native hutia was closely related to Desmarest’s hutia and went extinct after the arrival of Europeans.

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.

Why are Canadian moose declining? Interviews with Indigenous communities offer new clues
- Ecologists are unclear why moose populations in Ontario, Canada, have declined by 20 percent in the last two decades.
- University researchers and Indigenous community biologists combined peer-reviewed field studies and extensive interviews with First Nations tribal members to explore the possible reasons.
- Both sets of data pointed to climate change as the key factor, but stories and observations from tribal members offered many other potential causes overlooked by Western science.

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.

Nations should redirect 1% of military spending towards reforestation, Mexico proposes
- Mexico President Claudia Sheinbaum proposed to the world’s biggest economies to allocate 1% of their annual military spending, a total of about $24 billion, to support massive reforestation around the world.
- If carried out successfully, the effort could reforest an area equivalent to the surface of Guatemala, Belize and El Salvador combined.
- The President’s proposal comes at the same time as in Mexico the congress plans to cut funding for conservation in other government agencies.

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.

Court throws out permits for controversial Baja California hotel project
- The Tres Santos hotel project in Baja California Sur will have to conduct new environmental impact studies in order to obtain permits that it failed to comply with when breaking ground nearly a decade ago.
- Over the last decade, residents said the environmental impact became worse than what had originally been described to them. Some wetlands were filled in and rivers and streams were being diverted.
- Earlier this year, a court found that the original environmental impact study didn’t justify the development that was carried out. It should have been rejected and done again before construction even started.

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.

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.

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.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

At Mexico’s school for jaguars, big cats learn skills to return to the wild
- In Oaxaca, southern Mexico, a multidisciplinary team is launching a program to return rescued wildcats to their natural habitat.
- The program is run by the foundation Jaguares en la Selva (Jaguars in the Wild) at the Yaguar Xoo sanctuary, where two wildlife enclosures have been designed for jaguars and pumas to learn to hunt and survive on their own.
- In 2021, the program successfully released two jaguars and is currently working to reintroduce two more jaguars and three pumas back into their natural habitats.

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.

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.

In Mexico, Totonac spiritual guides work with scientists to revive ecosystems
- Abuelos de Tajín, spiritual guides from Totonac communities in Mexico, say people are losing their traditional beliefs and ancestral knowledge as their connection with a fast-degrading environment rupture.
- Totonac spirituality is strongly connected to the surrounding ecosystem: Losing biodiversity can precipitate the decline of traditional beliefs, and this loss of traditional spirituality further ruptures values and duties to protect the ecosystem.
- To assess and tackle the state of biodiversity loss and contamination in their environment, the spiritual guides are working with researchers from the National Autonomous University of Mexico City. Preliminary results show the deforestation rate increased by 44.4% from 1986 to 2023 in one region.
- Spiritual guides are trying to restore and “renovate” their rituals, spirituality and community identity as a way to strengthen their connection to their environment, conserve it and live abundant lives.

‘Mermaids’ dive to study and protect Mexican fishing grounds
- For more than 20 years, a fishing cooperative in the community of Isla Natividad, in Baja California Sur, Mexico, has been working to adapt and to be more resilient to climate-change impacts like tropical storms, marine heat waves, hypoxia and loss of kelp forests; these latter shelter species that help feed the community but have experienced mass mortality, such as the abalone.
- The community has invested in diversifying their economic activities and have established volunteer-run marine reserves. Their aim is to help affected fish stocks recover.
- A group of citizen scientist divers known as the Sirenas de Natividad was founded in 2019; this all-women team is made up of five homemakers, all wives and daughters of fishers, who are monitoring fishery resources and the volunteer-run marine reserves.

Celestún refuge fights illegal fishing & helps revive species in Mexico’s Yucatán
- In 2019, the Celestún fishing community in Yucatán, Mexico, established a 324-square-kilometer (125-square-mile) Fishing Refuge Zone (FRZ), the largest in the Gulf of Mexico.
- The area was created in response to the overfishing of sea cucumbers, a species that had been in rapid decline, which caused social strife in the community.
- Local fishers have been trained to monitor the refuge to help the species recover and protect other species of commercial interest, like octopus and lobster. The participation of women has been an important part of the process, as they help lead community monitoring efforts.

In Mexico, scientists race to save Marietas Islands’ corals from ocean warming
- Temperatures in the Pacific Ocean broke records in 2023 as climate change and El Niño destroyed a large part of Mexico’s Islas Marietas National Park.
- Only a fifth of the coral coverage registered in 1995 still survives, experts say.
- But scientists working on the islands have discovered individual corals that can resist higher temperatures, creating hope that the corals can recover.

Mexico loses phosphate mining lawsuit in controversial arbitration process
- Odyssey Marine Exploration, a deep-sea mining company based in Florida, sued Mexico after rejecting environmental permits for a phosphate mining project off the coast of the state of Baja California Sur.
- The company brought Mexico to arbitration through an obscure legal process known as an investor-state dispute settlement, which allows foreign companies to directly sue countries they’ve invested in.
- Investor-state dispute settlements have been criticized for their lack of transparency and public participation, offering few guaranteed rights to affected communities.

As logging intensifies forest fires, Wet’suwet’en fight to protect old growth
- Members of Wet’suwet’en Nation in British Columbia want to conserve a pristine old-growth watershed, Caas Tl’aat Twah, in its traditional territory. The nation has obtained a logging deferral for Caas Tl’aat Twah and is planning how to protect it permanently.
- Scientists have shown that industrial logging can increase fire intensity in forests by drying out the land. Conserving remaining intact forests such as Caas Tl’aat Twah can prevent fires from getting even worse, they say.
- After decades of large-scale industrial logging only 20% of old growth forests remain in British Columbia. In 2020, the province reported that one-quarter of remaining forests were at high risk for logging and pledged to pause cutting while making land use decisions.
- But four years on, less than half has been deferred — and the province could ultimately authorize logging it.

Lab-grown corals resisted bleaching during Caribbean’s worst marine heat wave
- In 2023, the Caribbean Sea experienced unprecedented heat: Beginning in March, sea surface temperatures throughout the region ranged from 1°-3°C (1.8°-5.4°F) warmer than normal.
- This unprecedented heat brought the worst coral bleaching event in the Caribbean’s recorded history, bleaching 60-100% of some reefs, and killing many patches.
- A new study found that certain species of coral propagated in the lab and then outplanted to restore reefs in five countries showed few signs of bleaching despite the prolonged marine heat wave, faring better than wild corals or corals propagated from fragments.

Lack of research as contaminated Yaqui River poses health risks
- Amid a water crisis, Yaqui communities in the northwestern Mexican state of Sonora lack safe drinking water due to contamination by arsenic, salinity and heavy metals as unveiled by several studies over the years.
- The water crisis, driven by decades of overexploitation, unequal water distribution and drought, intensifies contamination, particularly affecting coastal areas with saltwater intrusion and surpassing safe limits in certain regions.
- Members of the Yaqui tribe blame mining operations and agribusiness for the contamination, but there are few studies to confirm their source.
- They argue contamination has led to diabetes and health complications among community members, as well as cultural impacts.

A Mexican marine park shelters giant manta rays: Interview with Madalena Pereira Cabral
- For more than four years, marine biologist Madalena Pereira Cabral has been dedicated to investigating and understanding the movements of giant manta rays (Mobula birostris) in Revillagigedo National Park in the Mexican Pacific.
- Using satellite tags, the expert aims to describe these animals’ routes through the ocean and the reasons behind the fact that almost all the individual manta rays she has been studying end up leaving the marine protected area. Leaving this area exposes them to fishing pressure, which puts them at risk.
- One of the scientist’s most important findings is that giant manta rays’ movements and the groups they form are influenced by the El Niño phenomenon. This information is crucial for the conservation of this little-understood species.

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.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

In Mexico, avocado suppliers continue sourcing from illegally deforested land
- Suppliers Calavo Growers, Fresh Del Monte Produce, Mission Produce and West Pak Avocado purchased avocados from land where forests have been cleared illegally, according to a recent investigation.
- Climate Rights International and Mexican NGO Guardián Forestal looked at Mexican avocado shipping records from 2023 and the first trimester of 2024, finding 60 instances of companies buying avocados from deforested land.
- The states of Michoacán and Jalisco produced over 2 million avocados last year, making it one of the area’s top industries. But residents there complain of water shortages and other environmental impacts.

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.

On Canada’s West Coast, clam gardening builds resilience among Indigenous youth
- The Nuu-chah-nulth Youth Warrior Family, also known as the Warrior Program, fosters leadership skills in boys and young men across several Indigenous Nuu-chah-nulth nations on the west coast of Vancouver Island in British Columbia, Canada.
- This youth-led program involves taking younger community members into ancestral lands for a variety of traditional activities, among them building and reviving clam gardens, an ancient maricultural method.
- Clam gardens consist of terraced rock walls built across small coastal bays that allow tidal sediment to accumulate and transform rocky or steep shores into flat, productive areas for clams.
- Clam garden construction and care, along with other cultural practices, such as hunting, spearfishing and medicinal-plant foraging, serve as rites of passage, helping Warrior Program youth reconnect with their heritage.

Mexican fishing industry rep killed after denouncing illegal fishing
- Minerva Pérez Castro, the Baja California representative for the Mexican fishing industry’s main trade group, was killed in July after speaking out against the presence of organized crime in the fishing industry.
- Sophisticated organized crime groups have long participated in illegal fishing in northern Mexico, one of the most important producing areas for the country’s prominent fishing industry.
- The residences of several suspects have been searched, according to the Attorney General of the State of Baja California.

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.

Biomass power grows in Japan despite new understanding of climate risks
- New biomass power plants continue to come online in Japan, requiring an ever-greater quantity of imported fuel. The government’s feed-in tariff scheme, which has been tweaked but not canceled, incentivized these projects.
- Although understanding of forest biomass’s negative environmental and climate impacts is growing in Japan, policy advocates say operators of existing biomass power plants need to pay back construction bank loans, and the government’s refusal to admit its mistake is keeping biomass plants running.
- A major biomass fuel type is wood pellets, which in Japan is presently primarily sourced from plantation forests in Vietnam and primary forests in British Columbia, Canada. While BC ecologists have spoken out against wood pellets, and found allies in Vietnam, the biomass issue has proved challenging for Japan’s forest advocates.
- Though historically a small source of wood pellets for Japan, the growing popularity in Indonesia of pellets for both export and domestic use risks tropical forests there being cleared to make way for biomass energy plantations, NGOs warn.

In Sonora, communities fight mining to defend their water
- Since June 2, protesters have blocked mining company Grupo México from extracting water in the Sonoran town of Bacoachi, in northwest Mexico.
- Locals say the company has overexploited water resources during a regional drought, putting their livelihoods and public health at risk.
- The company owns the rights to more than half of the watershed’s total volume, according to a government analysis published in 2023.
- The ongoing protest comes as local advocacy groups are preparing to mark the 10th anniversary of an infamous waste spill from the same mine in August 2014.

Conservationists look for new ways to fight oil pipelines in southern Mexico
- Pipelines currently under construction in southern Mexico have become controversial because of threats of chemical spills, their contribution to climate change and the alleged lack of consultation with local communities.
- The projects include the Southeast Gateway Gas pipeline and Tuxpan-Tula pipeline, both constructed by the Federal Electricity Commission and the Canadian company TC Energy.
- A 2018 injunction against the Southeast Gateway Gas Pipeline was struck down after a court ruled the project was a matter of national security. Now, local communities and conservation groups are working to develop alliances with international groups to come up with a different legal strategy.

After 2-year wait, Sonoran wilderness protection law gets closer to reality
- In June 2022, the northwest Mexican state of Sonora’s Congress unanimously voted to create the country’s first easement system to protect privately owned wilderness spaces from development.
- For more than two years, the law was not published in the state’s legal register, so it never came into effect. In that time, at least two private conservation areas with the highest existing level of protection have been threatened by development.
- The law was finally published earlier this month, possibly with up to another year before the government publishes guidelines and the first easement is declared. At least two reserves plan to apply, and advocates hope their example will encourage other Mexican states to legislate easement designations.

Loss of water means loss of culture for Mexico’s Indigenous Yaqui
- The sacred waters of the Yaqui tribe in the northwestern Mexican state of Sonora have dried up after decades of overexploitation, unequal water distribution and drought.
- This poses serious threats to Yaqui culture, which previously used certain sections of the Yaqui River for traditional ceremonies.
- It has also led to the decline of plant and tree species, such as the alamo (Ficus cotinifolia) and the giant reed (Arundo donax), which are used to build traditional structures in Yaqui villages.
- Important features of the Yaqui ritual dance, known as the pascola and deer, rely on the cocoons of the four-mirror butterfly, an endemic species that depends on the Yaqui River for its survival and is in decline.

A year after toxic tar sands spill, questions remain for affected First Nation
- Canada’s tar sands are the fourth-largest oil deposit in the world, but separating the bitumen creates large volumes of toxic wastewater, which is stored in tailings ponds that now cover 270 km² (104 mi²). Many experts warn that contaminants from mining and the tailings ponds are entering the environment
- In 2023, 5.3 million liters (1.4 million gallons) of industrial wastewater breached a tailings pond at a tar sands site in Alberta province, raising fears in an Indigenous downstream community. Then the town learned a second tailings pond had been leaking toxic wastewater for at least nine months.
- In March 2024, the Athabasca Chipewyan First Nation sued the Alberta Energy Regulator over its poor handling of the spills along with alleged regulatory failures. The case is ongoing.
- The incident highlights continuing concerns about the impacts of the tar sands industry on human health and the environment. Experts say government and industry plans for tailing pond cleanup and landscape restoration are far behind schedule, with no viable options now on the table to deal with the fast-growing volume of stored toxic wastewater.

As drought parches Mexico, a Yaqui water defender fights for a sacred river
- In the northwestern Mexican state of Sonora, Mario Luna Romero faces constant threats to his life for fighting to protect his community’s rights to its water in the region.
- Within the Yaqui Territory are the remnants of the Yaqui River, which is sacred to the Indigenous tribe and has been drained of all its water after decades of overexploitation, unequal water distribution and droughts.
- Luna was arrested in 2014 and spent a year and 11 days in a maximum-security prison; meanwhile, other colleagues have been harassed by government officials or killed by criminals.
- Mexico, including the Yaqui Valley, is experiencing a deadly heat wave, drought and water shortages.

It’s the bee’s needs: Study finds best plants for bee health, conservation
- A new study analyzed pollen from 57 North American plant species, identifying those most nutritionally beneficial for bees, which could inform conservation efforts and wildflower restoration projects.
- Based on their findings, the researchers recommend emphasizing roses (Rosa sp.), clovers (Trifolium sp.), red raspberry (Rubus idaeus), tall buttercup (Ranunculus acris), and Tara vine (Actinidia arguta) in wildflower restoration projects, citing their ideal protein-to-lipid ratios in pollen for wild bee nutrition.
- The research found that bees require a diverse diet from multiple plant sources to obtain a balanced intake of fatty acids and essential amino acids, as no single plant species provides the optimal nutrition.
- With many bee species facing significant threats, the researchers say they hope these findings can inform conservation efforts from policy changes to individual actions like planting native flowers and reducing pesticide use.

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.

The Wixárika community’s thirteen-year legal battle to stop mining in their sacred territory
- Wirikuta is the most important sacred place for the Indigenous Wixárika people in the state of San Luis Potosí, Mexico.
- In 2010, the communities discovered that mining companies were threatening this place, which is of great importance for biodiversity and culture.
- Since then, they have been fighting a legal battle to expel the 78 contracts threatening the site’s existence.
- Although mining activity is currently suspended thanks to a protection order obtained by the Indigenous community, there is still no definitive resolution. In 2024, they hope this will finally change, and the Mexican judicial system will rule in their favor.

The health impacts of escalating megafires are everyone’s problem
- Increases in extreme wildfires in many parts of the world are fueling concerns over the impacts of smoke on human health, with global warming, forest management and land-use change the primary drivers of increasing wildfires.
- Similar to other types of air pollution, wildfire smoke is associated with a wide range of short-term health impacts, especially for vulnerable groups such as the elderly and people with preexisting medical conditions.
- Wildfire smoke is increasingly adding to the cumulative air pollution burden experienced by modern industrial societies — even in remote or rural areas.
- Emerging evidence also suggests wildfire smoke may have long-term health impacts and contribute to increased risk of chronic conditions.

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.

Canada’s 2023 wildfires outsmoked global aviation, yet emissions go uncounted
- Canada’s 2023 wildfires burned an area nearly the size of Ireland, releasing emissions equivalent to four times the global aviation sector.
- Climate change creates longer, more severe fire seasons, leading to a dangerous feedback loop of increasing emissions.
- Canada’s emissions accounting method excludes wildfire emissions from U.N. reports, a practice questioned by some experts.
- Wildfires disproportionately impacted First Nations and Indigenous communities, whose traditional fire management practices could help mitigate risks.

Photos: Exploring Mexico City’s Aztec-era farms, the chinampas
- Chinampas are part of an agricultural system developed during the Aztec Empire in shallow lakes or marshes in the southern valley of what is today Mexico City.
- The system consists of elevated, narrow platforms used as fields that are surrounded by water canals, and is considered one of the most intensive and productive farming systems ever developed.
- However, for decades, chinampas have faced increasing threats due to urbanization, the overexploitation of water resources, water contamination and unregulated tourism, as well as the growing rejection of chinampa culture by traditional farmers and the loss of ancestral knowledge.

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.

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.

Indigenous communities make clean energy drive work for, not against, them
- Indigenous peoples have been steadily warning about the impacts of renewable energy development on their lands and communities, but some see a way to harness this trend for the positive.
- Experts say Indigenous communities can play a leading role in the clean energy transition through partnerships that allow them to produce and benefit from renewable energy projects.
- In Canada, policy initiatives like the feed-in tariff program in Ontario province have encouraged Indigenous participation in renewable energy by providing incentives for Indigenous ownership in projects, making them a growing shareholder in Canada’s clean energy transition.
- While there are examples to be taken from Canada’s approach, barriers remain, including limited capacity within communities, access to capital, and governance structures supporting such partnerships.

Alaska’s Arctic rivers turn rusty orange as permafrost thaws
- Numerous rivers and streams in Alaska’s remote Brooks Range are turning orange due to the thawing of permafrost, which is releasing previously frozen minerals into the water.
- Water samples from the affected streams show higher acidity and higher concentrations of sulfates and trace metals, which can have significant ecological consequences, such as the disappearance of fish species and a decline in aquatic insect diversity.
- These water quality changes could severely impact Arctic fish populations, as many of the affected streams serve as crucial spawning grounds and nurseries for salmon and other fish species that are essential to the ecosystem and local subsistence fisheries.
- Researchers emphasize the need for further studies to understand the long-term implications of this issue, highlighting that the abrupt changes in water chemistry observed in the Brooks Range are a unique and concerning consequence of climate change in the Arctic.

Scientists and farmers restore Aztec-era floating farms that house axolotls
- In 1987, UNESCO declared the Xochimilco wetland area in southern Mexico City a World Heritage Site, recognizing in particular its chinampas, an ancient agricultural system in use since the time of the Aztecs.
- In the past few decades, Xochimilco’s levels of production and of biodiversity have shifted: people have changed the purpose of many chinampas, and the population of axolotl salamanders, an iconic species endemic to the area, has decreased drastically.
- Scientists from the Ecological Restoration Laboratory at the National Autonomous University of Mexico and farmers from the area are promoting a comprehensive restoration program to conserve this group of chinampas and all the living things that depend on it.

Elusive jaguarundi inspires biologists to share data across Latin America
- The jaguarundi (Herpailurus yagouaroundi) is a little-known small felid with a range extending from northern Argentina to Mexico. The last confirmed sighting in the United States was in 1986.
- H. yagouaroundi is found in a variety of habitats, but is thought to occupy mostly rugged areas with good shrub cover, including near agricultural lands. Unlike most other felids, the jaguarundi is active during the day, which can easily bring it into conflict with farmers who don’t appreciate its habit of raiding chicken coops.
- Like most small, noncharismatic cat species, there’s little funding to learn more about the jaguarundi. But researchers are developing new tools, for example pooling sparse “bycatch” data gathered by many biologists from camera traps in widely scattered places and modeling it to predict habitat use and population size.
- An ongoing IUCN jaguarundi assessment is using a Google Forms questionnaire to reach out widely to researchers, governments and NGOs, while also using easily shared social media tools. A detailed understanding of jaguarundi behavior is needed to assure it is conserved both inside and outside protected areas.

Yucatán Peninsula’s hidden underground life tracks changes at the surface
- Scientists from Northwestern University in the U.S. led a series of underwater expeditions collecting water samples from the deep web of caves and sinkholes in the Yucatán Peninsula.
- The southeastern region of Mexico is crisscrossed by numerous flooded and interconnected tunnels, functioning as subterranean rivers — crucial arteries that maintain ecosystems and support millions of people, and connecting directly to the sea.
- Any disruptions to the microbial communities in these waters could have significant consequences for both humans and marine ecosystems.
- This research is crucial for assessing the potential environmental impacts of large-scale agriculture or major projects like the building of the Tren Maya railway line.

What’s at stake for the environment in Mexico’s upcoming election?
- On June 2, in addition to president, Mexico will choose all 500 deputies in the lower house of Congress and all 128 seats in the Senate.
- The main presidential candidates are left-wing Claudia Sheinbaum and right-wing Xóchitl Gálvez, with center-left Jorge Máynez representing a third, dark-horse option.
- Both Sheinbaum and Gálvez want to invest more in renewable energy, but disagree about some controversial infrastructure projects.

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.
