San Gabriel Mountains National Monument expanding by more than 100,000 acres

Thursday, May 2, 2024

President Biden on Thursday will expand the San Gabriel Mountains National Monument by nearly a third in an action that is being widely praised by the Indigenous leaders, politicians, conservationists and community organizers who had long fought for the enlargement of the protected natural area that serves as the backyard of the Los Angeles Basin.The president will also sign a proclamation expanding the Berryessa Snow Mountain National Monument by adding the 13,696-acre Molok Luyuk, or Condor Ridge, to the 330,000-acre swath of rolling oak woodlands, lush conifer forests and dramatic rock formations along Northern California’s inner Coast Range. Aggressive and impactful reporting on climate change, the environment, health and science. Biden’s actions put in place stronger federal protections for areas that were left out when each monument was initially set aside by then-President Obama, in 2014 in the case of the San Gabriel Mountains, and the following year for Berryessa Snow Mountain. Advocates say the designations will expand underserved communities’ access to open space and better preserve sacred and historic Indigenous cultural sites. The move also came as the commander in chief has sought to boost his conservation record heading into the presidential election.“It’s a huge deal on so many levels,” said Sen. Alex Padilla, who had previously introduced legislation that would have expanded both national monuments. That legislation remains active, but lacks the Republican support in Congress to bring it to the finish line, he said.As a result, Padilla and Rep. Judy Chu of Monterey Park last year urged Biden to bypass Congress and instead issue a presidential proclamation under the Antiquities Act of 1906, which the president is expected to do Thursday. “I’m exceptionally proud to have worked in Congress with Sen. Padilla, other local, state, and federal elected officials, and many local advocacy groups for over a decade to highlight the significance of the San Gabriel Mountains to our environment, economy and health,” Chu said in a statement. Millard Falls, at the base of the San Gabriel Mountains near Altadena, is part of the expanded national monument. (Mel Melcon / Los Angeles Times) The expansion of each monument was the culmination of years-long grassroots campaigns by conservation organizations, community groups and tribes, Padilla said.“A lot of work went into the initial monument designations under President Obama, but the areas that are being added now were part of the initial vision, just not included in the initial designation,” he said. “So it’s finally completing the vision.”The move adds nearly 106,000 acres to the 346,000-acre San Gabriel Mountains National Monument, which sits within an hour’s drive of 18 million people, extending its boundaries to the edge of San Fernando Valley neighborhoods including Sylmar and Lakeview Terrace, as well as the city of Santa Clarita. Those are some of the hottest regions within L.A. County, and home to communities of color that have historically lacked access to nearby green spaces, said Belén Bernal, executive director of Nature for All, a coalition of environmental and community groups that has long campaigned for more parks and safe outdoor opportunities, including the expansion of the monument.“As a Latina, I believe that we, people of color, given our income status and that a lot of our family members are immigrants to this country, we have been deprived of nearby nature in our neighborhoods,” Bernal said.Stretching from Santa Clarita to San Bernardino, the San Gabriel Mountains watershed provides Los Angeles County with 70% of its open space and roughly 30% of its water. Already, the Angeles National Forest attracts nearly 4.6 million visits a year — more than Grand Canyon or Yosemite National Park. The added protections will help ensure equitable access to the San Gabriels’ cool streams and rugged canyons, while also preserving clean air and water, Bernal said.Leaders of Indigenous groups — including the Fernandeño Tataviam Band of Mission Indians and the San Gabriel Band of Mission Indians Gabrieleno/Tongva — were part of the coalition that pushed for the expansion. “Expanding the monument helps protect lands of cultural importance to my people, who are part of this nation’s history and who have cared for these lands since time immemorial,” said Rudy Ortega Jr., president of the Fernandeño Tataviam Band of Mission Indians, in a statement heralding the announcement. “It also further protects areas that are critical for our environment and the wildlife and plants that depend on this landscape.”The expansion will protect Bear Divide, a slot in a ridgeline overlooking Santa Clarita that is used by thousands of migrating birds as they make their way from Central America toward the Arctic. It will also preserve habitat for black bears, mountain lions, coyotes and mule deer, along with rare and endangered species, including Nelson’s bighorn sheep, mountain yellow-legged frogs and Santa Ana suckers.

As part of the agreement, the ridge will be officially renamed from Walker Ridge to Molok Luyuk, which means Condor Ridge in the Patwin language.The expansion provides the Patwin tribes with the opportunity to co-steward Molok Luyuk with the Bureau of Land Management, which manages the monument, Anthony Roberts, tribal chairman of the Yocha Dehe Wintun Nation, said in a statement.“Notably, the renaming of Walker Ridge to Molok Luyuk recognizes the Patwin ancestry of this area of California, whose traditional territory stretches south from these hills to the shores of San Pablo Bay and east to the Sacramento River,” he said. “It also highlights the restoration effort being made by our Tribes to reintroduce the California Condor to the ridge,” he said.Molok Luyuk was initially left out of the 2015 monument designation because of multiple attempts to put a wind energy project on the ridge. The project was eventually shelved over a variety of issues, said Sandra Schubert, executive director of Tuleyome, a conservation nonprofit that has been trying to win protections for the piece of land for more than 20 years.As the spot where two tectonic plates meet, Molok Luyuk has unique soils, plants and geological features that make it a popular spot for scientists to study, Schubert said.“Think of walking like 100 yards, and you’re literally walking through millions of years of history because of the geology,” she said. “That unique geology also leads to unique, rare species, especially of plants.”Although Molok Luyuk makes up about 0.2% of California’s acreage, it supports a staggering 7% of the state’s native plant diversity, including rare plants like the adobe lily and Purdy’s fritillary, as well as the world’s largest known stand of MacNab cypress, said Jun Bando, executive director of the California Native Plant Society, which was also key in pushing for the expansion.The designation also paves the way for the piece of land to be included in Berryessa Snow Mountain’s national monument plan, which helps ensure it is adequately protected, she said.“Molok Luyuk is an area that is sacred to the local tribes and it’s also really unique in terms of the degree of biodiversity that it supports,” Bando said.Vice President Kamala Harris said in a statement that she fought for public land protections as a U.S. senator from California and thanked both Biden and local advocates for making the expansions a reality.“These expansions will increase access to nature, boost our outdoor economy and honor areas of significance to tribal nations and Indigenous peoples as we continue to safeguard our public lands for all Americans and for generations to come,” she said.Big picture, the national monument designations are key to the goal — put forward by a team of international scientists and adopted by California — of protecting 30% of lands and coastal waters by 2030, Bando said. “This goal isn’t a ‘nice to have,’” she said. “It’s part of urgent international action to address the intertwined crises of climate change and extinction.”

The Biden administration added to the Southern California monument that was established by President Obama in 2014, and also expanded the Berryessa Snow Mountain National Monument in Northern California.

Costa Rica Probes Osa Permits in Fila Costeña Amid Eco Concerns

Costa Rica’s Comptroller General of the Republic (CGR) has accepted a complaint and sent it to its oversight unit for review. The focus is on construction permits issued by the Osa Municipality in the Fila Costeña, a mountainous area in the southern Pacific region. The move follows claims of unchecked real estate growth in fragile zones. The complaint came from the Community Alliance Commission (CAC), linked to the Paso de la Danta Biological Corridor’s local committee, with support from the Frente Amplio party’s legislative group. They argue that the municipality approved building projects without solid scientific backing to protect the environment. In a December 17 letter, referenced as DFOE-DEC-9527, the CGR confirmed it would include the issue in its audit planning. Fila Costeña, also called the Brunqueña Range, stretches along the Pacific coast from the Savegre River to the Térraba River. It covers about 82,000 hectares in the Paso de la Danta Biological Corridor, linking coastal habitats to inland rainforests. The area features steep slopes, heavy rains, and diverse wildlife, making it a key spot for conservation. Real estate development has picked up since the early 2000s, leading to forest loss, habitat breakup, and more sediment flowing into marine areas. This has harmed water sources and weakened the corridor. The CAC points out that residential projects over the last 20 years have cut forest cover, strained natural springs that supply drinking water to local towns, and boosted runoff to coastal zones. Biologist Jorge Lobo, a retired professor from the University of Costa Rica (UCR), has tracked the region for years. He links the damage mainly to tourism-driven real estate, with homes built for foreign buyers on land sold by locals. Lobo notes the trend sped up after 2005, spreading to higher elevations and the Maritime Terrestrial Zone (ZMT). Through aerial photos and small plane surveys, Lobo has mapped expanding access roads from the coastal highway, creating a web across the hills. These show earthworks, terraces, and supports on steep land for new homes. He lists three main effects: biodiversity loss on land and sea from broken forests; higher erosion risks in clay soils during strong rains, raising landslide chances; and reduced water flow. Changes to the land disrupt how water soaks into aquifers, cutting supplies for nature and people. The CGR’s review will check if permits followed environmental rules and land use plans. This includes assessments by the National Environmental Technical Secretariat (SETENA). A recent CGR report on SETENA found that 90% of projects get approved without field checks, highlighting risks of oversight gaps and conflicts. The complaint also notes missing data: details on water capacity in Fila Costeña springs, current forest health, and protection zones. Dozens of springs start here, feeding places like Dominical, Palmar Norte and Sur, Uvita, Ojochal, and Bahía Ballena. At least 60 water uses are handled by 18 community water and sewer groups (ASADAS). These sources support local life and tourism growth in the canton. Environmental groups call for quick steps, such as a freeze on new permits, an updated local zoning plan, a special protection category for the range, and public talks. Support grew at the 2025 Ocean Festival, where attendees pushed for accountability from the Osa Municipality. Communities and experts stress the need to safeguard this area for water security and ecology in the southern Pacific. The CGR will share findings with those who filed the complaint after the review ends. For now, the push continues to balance growth with protection in this vital region.

Pumas Are Snacking on Penguins in Argentina—and the Abundant Birds Are Changing the Prowling Cats' Behavior

Mountain lions are adapting to their defenseless, predictable prey, which return to Patagonia seasonally to nest and breed, new research suggests

Pumas Are Snacking on Penguins in Argentina—and the Abundant Birds Are Changing the Prowling Cats’ Behavior Mountain lions are adapting to their defenseless, predictable prey, which return to Patagonia seasonally to nest and breed, new research suggests Sarah Kuta - Daily Correspondent December 18, 2025 10:45 a.m. Magellanic penguins are easy prey for the large cats. Tompkins Conservation / Rewilding Argentina Roughly a century ago, European sheep herders began settling Argentina’s Patagonia region and killed off as many potential predators as possible to protect their flocks. Pumas, also known as mountain lions and cougars, mostly disappeared from the landscape, which allowed other creatures—including Magellanic penguins—to thrive. In recent decades, however, pumas have started to rebound. And the cats’ return has led to some unexpected ripple effects: Mountain lions, which are typically solitary animals, are now congregating near seasonal Magellanic penguin colonies to feast upon the little black and white birds, scientists report in a paper published December 17 in the journal Proceedings of the Royal Society B. The researchers set up 32 trail cameras to gather photos and videos of the interactions. Tompkins Conservation / Rewilding Argentina Once pumas were extirpated from the region in the early 20th century, the Magellanic penguins started to move in from nearby islands. Without four-legged predators roaming around, they apparently felt safe and comfortable enough to start breeding on the mainland. Today, their coastal colonies can include tens of thousands of nests. In 2004, Argentina established Monte León National Park to protect a large swath of coastal Patagonia. The creation of the park helped pumas regain their foothold in the region and led to a novel predator-prey relationship between the large cats and the mid-sized penguins. Did you know? Pumas aren't "big cats" Despite their large size, mountain lions aren’t considered “big cats” by scientists. That name technically refers to members of the genus Panthera, which includes lions, tigers, jaguars, leopards and snow leopards. Pumas are the only living members of the Puma genus. Scientists knew mountain lions were snacking on Magellanic penguins—anecdotal reports started popping up around 2007, study co-author Emiliano Donadio, science director at the Fundación Rewilding Argentina, tells BBC Wildlife Magazine’s Graeme Green. But Donadio and his colleagues wanted to learn more about how this new food source was affecting the predators’ behavior and movements. Penguins spend part of the year on the coast, during their breeding season, and the rest of the year at sea foraging, so the natural conditions were ideal for research. Did pumas behave differently when the penguins were present versus when the birds were absent? Researchers put GPS collars on 14 pumas within the park, then tracked their movements from September 2019 to December 2023. They also set up 32 wildlife cameras to watch the cats’ behavior and estimate their numbers when penguins were present versus when they were absent. Researchers put GPS tracking collars on 14 pumas in the park. Tompkins Conservation / Rewilding Argentina The data showed clear evidence that the pumas had adapted to their new prey. When the penguins showed up and started nesting, the pumas shrank their territories, the study revealed. And when the birds returned to the water at the end of the breeding season, the cats expanded their territories once again. Regardless of the penguins’ presence, about 13 pumas roamed per 39 square miles, the team found. That’s the largest density of pumas ever documented at one site, which is roughly double the density of the past record-holding location. This means the solitary cats were interacting with each other more often—and doing so relatively peacefully. The results suggest mountain lions are more tolerant of each other when there’s a smorgasbord of defenseless, predictable, easy-to-snatch prey around—similar to how bears typically congregate without incident along northern rivers during the annual salmon run. Mountain lions are spending more time near each other when the penguins are nesting. Tompkins Conservation / Rewilding Argentina “We tend to think of pumas as extremely aggressive and intolerant,” Donadio tells National Geographic’s Meghie Rodrigues. “But when food is abundant and concentrated, there’s no need to defend it.” The findings weren’t necessarily surprising to the researchers, as mountain lions are an “incredibly resilient species,” says study co-author Mitchell Serota, an ecologist at Duke Farms, a center of the Doris Duke Foundation, to ABC News’ Julia Jacobo. They inhabit a wide range, from Canada to nearly the southern tip of South America, and they thrive in a variety of ecosystems, including forests, grasslands, shrublands and deserts. They’re also known to have diverse diets and seem willing to take advantage of whatever prey is available—whether that’s tiny mice or enormous elk. Jake Goheen, a wildlife ecologist at Iowa State University who was not involved with the research, agrees, telling the New York Times’ Alexa Robles-Gil the findings represent “an extraordinary example of how flexible large carnivores can be.” Scientists don't know how many penguins the pumas are killing. Tompkins Conservation / Rewilding Argentina For now, the study authors say their research has only scratched the surface. They don’t know the long-term effects on the penguins’ numbers, although recent surveys suggest the birds’ population is growing. And mountain lions in the region usually hunt guanacos, a four-legged relative of the llama, so how might their seasonal penguin feasts affect their predation of these creatures? Moreover, the findings demonstrate the complexity of animal reintroduction and environmental restoration efforts. Contrary to popular belief, reintroducing large carnivores doesn’t mean an ecosystem will revert to its historic state. “When we start to rewild the land, the species that are coming back might find a system that is a bit different from the one that they used to inhabit 100 years ago—and they adapt to it,” Donadio tells National Geographic.

California wildlife officials quietly shift on killing a high-profile predator

California wildlife officials are now allowing mountain lions to be killed to protect endangered bighorn sheep, changing a nearly decade-long practice of just moving them.

In a move that reverses nearly a decade of practice, California wildlife officials have quietly begun to allow killing mountain lions in order to protect another iconic native — bighorn sheep.Though limited to the Eastern Sierra — the steep, rugged home of a rare type of the wild sheep — it marks a sea change for California, where legislators and voters have heaped protections on the big, charismatic cats that suffered decades of persecution.It’s a complex story — a lesson in ecosystems that involves three linked species and efforts to do right by all of them.While some are thrilled, many are dismayed. Some think it’s the wrong tack while others say it doesn’t go far enough to safeguard yet another beloved animal: deer. The policy change came into relief recently. In the craggy Sierra Nevada mountains, late last year, a male lion hunted down several bighorn. They GPS-collared him and he killed another sheep.He was young enough that he hadn’t started breeding or fully established a home range, so wildlife officials caught him and hauled him to what was supposed to be his new home.But about six months later, he wandered back to sheep country and killed again.So this summer they put him down by lethal injection, according to Tom Stephenson, who leads the Sierra Nevada bighorn recovery program for the California Department of Fish and Wildlife.How we got hereThe moment lies at the intersection of politics and biology. And it wouldn’t have happened without an important Eastern Sierra contingent — hunters.In February of last year, Brian Tillemans submitted a petition to the California Fish and Game Commission spotlighting concerns about dwindling numbers of Eastern Sierra mule deer, as well as bighorn sheep. The local hunter, who is also a former watershed resource manager for the L.A. Department of Water and Power, told commissioners the mountain lion population had “exploded” in the region. Hundreds of area residents signed the petition. Brian Tillemans, a hunter and former watershed resource manager for the L.A. Department of Water and Power, sits outside the town of Bishop, near Mt. Tom, in an area where Sierra Nevada bighorn visit. (Jason Armond / Los Angeles Times) “The emotional biopolitics of protecting mountain lions is leading to the demise of two iconic species,” Tillemans told commissioners. His plea hit a nerve. It sparked a series of discussions that led the state to revise its approach to managing lions.Mountain lions in California are a “specially protected species” and it’s illegal to hunt them for sport. But they can be lawfully killed in limited situations. One is when the hefty cats are threatening Sierra Nevada bighorn, one of two subspecies of the sheep that live in the Golden State. (The other type, desert bighorn, prefer the arid Mojave Desert and mountains of Southern California over snowy Sierra peaks.) California lawmakers gave that right to state wildlife officials in 1999, the same year Sierra Nevada bighorn landed on the federal endangered species list.In 2017 though, wildlife officials stopped killing lions preying on sheep and began relocating them instead, Stephenson said. That has turned out to be successful for female lions and young ones. But males that have already established a home range proved tougher. They try their darndest to return to their mates. In what would become a highly publicized fail, two male lions from the Eastern Sierra died after being trucked more than 200 miles to a remote area of the desert.Bighorn, it seemed, were left vulnerable. Sierra Nevada bighorn began to recover after being listed as federally endangered in the late 1990s, but recent severe winters knocked the population down. At such low numbers, lions can take a heavy toll on them. (Stephen Osman / Los Angeles Times ) By the time bighorn sheep were listed under the Endangered Species Act, they had been driven to the brink of extinction by decades of hunting and diseases spread by domestic sheep. Once protected, they began to make gains. But several severe winters starting in 2016 knocked the fragile population down. At such low numbers, hungry lions can devastate herds. Their total population was about 400 last year. The lions in the Eastern Sierra area, meanwhile, are doing well for themselves. There are about 70 to 80 roaming the craggy mountains, which Stephenson described as a “relatively large” number. They feed on wild horses that roam the region, which may boost their ranks. Moving lions will still be the primary protection tool when feasible. But with bighorn in a precarious way, “we just recognize that we need to do everything we can to try to get this animal recovered,” Stephenson said. So lethal removal was put back on the table.John Wehausen, an applied population ecologist who has studied bighorn for more than half a century, is thrilled by the recent policy changes. He expects the bighorn to start to bounce back. Data support the effectiveness of removing lions to help the sheep, he said.He said it’s key for the agency to act quickly to move or euthanize a lion that’s feeding on sheep, to prevent it from harming more. He believes the agency was previously sluggish, but is now moving efficiently.“I’ve as much as said to them, ‘I don’t really care how you get [the lions] out of there. You just need to get them out of there in a timely way to protect these sheep because that’s what your job is,’” he said.But Beth Pratt, California regional executive director for the National Wildlife Federation, questions whether killing lions to protect sheep makes sense. Beth Pratt, of the National Wildlife Federation, hikes just outside the eastern entrance of Yosemite National Park, near the town of Lee Vining. (Jason Armond / Los Angeles Times) “Do you keep blowing away an animal for being an animal, when it’s clearly just not working?” she said. Many people “understand that predators have a place in healthy ecosystems.”Pratt wonders if there are creative solutions, such as bolstering the sheep population by bringing in animals raised elsewhere or stationing guard dogs around the herds.Disappearing deerFor Eastern Sierra natives such as Danny McIntosh, of Bishop, a small community about a four-hour drive north of Los Angeles beloved by hunters, climbers and hikers, deer represent a way of life.McIntosh has watched mule deer since he was a kid. He’s “infatuated” with bucks, which battle each other during mating season. Around his teen years, he started photographing the animals, named for their large, mule-like ears. He’s an avid hunter and also enjoys collecting “sheds,” antlers dropped annually by deer and elk.After the severe winter of 2018, he noticed a marked decline in the deer population that he said has only worsened.That observation largely tracks with state Department of Fish and Wildlife findings. According to a 2023 paper, what’s known as the Round Valley herd dropped 33% from 2016 to 2022. “What disheartens me the most is that my children will never get to experience, on the same level as I did, flourishing deer herds and the numerous traditional activities that surround them,” McIntosh told state wildlife commissioners during a meeting in June 2024.He largely blames lions and black bears, and isn’t satisfied with the state’s willingness to kill the big cats on behalf of bighorn. Though he acknowledged it will help the sheep, it’s not expected to have a meaningful impact on deer. “It’s still not enough,” McIntosh said. “Our deer were the healthiest and the herds were the strongest when there was trapping going on and there were no restrictions.”State wildlife officials don’t have the authority to control lions for the benefit of deer. Hunters want more deer, “and if someone can’t snap their fingers and make that happen, it’s frustrating” for them, said Stephenson, the state Department of Fish and Wildlife bighorn recovery leader. “There’s a limit to how many knobs we can turn to effect any sort of rapid change. It’s a long, slow process.”According to Stephenson, it’s complicated. Yes, bears and lions snack on deer. But fires can wipe out vegetation they rely on for food, too. Harsh winters, punctuated by drought, also take a toll.When there are so many factors, it’s hard to know which are most important in influencing the population, he said.Mule deer are dwindling not just here but across the West. In September, animal tracks dot the mud in a wildlife crossing installed under Highway 395 near the Eastern Sierra community of Bridgeport. (Jason Armond / Los Angeles Times) “We’re not concerned that the deer population is going to disappear over here,” Stephenson said. “I think it’s a concern from the perspective of a hunter who wants hunting opportunities, and who has seen that hunting opportunity change over the decades.”The promise of crossingsThere may be one solution everyone can get behind — something that could offer a lifeline to mule deer without the need to knock out lions. Hunters and conservationists alike support building a wildlife crossing in the top roadkill hot spot in the Eastern Sierra — a deadly stretch of Highway 395 that runs past the Mammoth Yosemite Airport. Car collisions are the second highest cause of death for deer, not counting unknown causes. On a sunny morning in September, a dead doe lay on the side of a small road just off 395, as cars whizzed by on the artery that connects communities along the Eastern Sierra.Scavengers had so far only ripped into her backside. Tillemans, the hunter from Bishop, who provided a tour of the area, said it meant she hadn’t been dead long.From 2002 to 2018, about 675 vehicles collided with deer in less than nine miles of roadway. It’s smack dab in the middle of the migration routes for the Round Valley and Casa Diablo herds, according to a recent study.A project is underway to build safe passage for fauna here. As envisioned, two overcrossings and two undercrossings would function as bridges across four lanes of traffic. But its future depends on lining up money — a lot of it. Additional planning and construction is estimated to cost more than $65 million, according to the California Department of Transportation, which is leading the effort. Ben Carter, a senior environmental scientist with the state Department of Fish and Wildlife, looks at animal tracks at a recently completed wildlife crossing in Bridgeport called the Sonora Junction Shoulders Project. (Jason Armond / Los Angeles Times) It could save the lives of untold deer. And it may be more plausible than allowing a lion hunting season, as some would like. That would require a change in state law.“If there’s ever a spot for a deer crossing, it’s up here,” Tillemans said while driving to the proposed project area.A recently completed crossing about 70 miles to the north may offer an example of what the other one could provide.In early fall, Ben Carter checked a camera positioned to capture the goings-on in a corrugated metal tunnel installed beneath a breathtaking stretch of the 395 north of the town of Bridgeport.Carter, a senior environmental scientist with the state Department of Fish and Wildlife, had pulled the SD card for the first time to see what critters might have been early adopters of the new wildlife undercrossing — one of two constructed as part of a shoulder-widening project.Tracks told their own tale. Cloven hooves had pressed into the soft mud. Deer had been there.

Colorado has wolves again for the first time in 80 years. Why are they dying?

Wildlife officials release five gray wolves on public land in northwestern Colorado on December 18, 2023. | Jerry Neal/Colorado Parks and Wildlife On a sunny morning two years ago, a group of state officials stood in the mountains of northwestern Colorado in front of a handful of large metal crates. With a small crowd watching them, the officials began to unlatch the crate doors one by one. Out of each came a gray wolf — arguably the nation’s most controversial endangered species.  This was a massive moment for conservation.  While gray wolves once ranged throughout much of the Lower 48, a government-backed extermination campaign wiped most of them out in the 19th and 20th centuries. By the 1940s, Colorado had lost all of its resident wolves.  But, in the fall of 2020, Colorado voters did something unprecedented: They passed a ballot measure to reintroduce gray wolves to the state. This wasn’t just about having wolves on the landscape to admire, but about restoring the ecosystems that we’ve broken and the biodiversity we’ve lost. As apex predators, wolves help keep an entire ecosystem in balance, in part by limiting populations of deer and elk that can damage vegetation, spread disease, and cause car accidents.  In the winter of 2023, state officials released 10 gray wolves flown in from Oregon onto public land in northwestern Colorado. And in January of this year, they introduced another 15 that were brought in from Canada. Colorado Parks and Wildlife (CPW) — the state wildlife agency leading the reintroduction program — plans to release 30 to 50 wolves over three to five years to establish a permanent breeding population that can eventually survive without intervention.  “Today, history was made in Colorado,” Colorado Governor Jared Polis said following the release. “For the first time since the 1940s, the howl of wolves will officially return to western Colorado.” Fast forward to today, and that program seems, at least on the surface, like a mess. Ten of the transplanted wolves are already dead, as is one of their offspring. And now, the state is struggling to find new wolves to ship to Colorado for the next phase of reintroduction. Meanwhile, the program has cost millions of dollars more than expected.  The takeaway is not that releasing wolves in Colorado was, or is now, a bad idea. Rather, the challenges facing this first-of-its-kind reintroduction just reveal how extraordinarily difficult it is to restore top predators to a landscape dominated by humans. That’s true in the Western US and everywhere — especially when the animal in question has been vilified for generations.  Why 10 of the reintroduced wolves are already dead One harsh reality is that a lot of wolves die naturally, such as from disease, killing each other over territory, and other predators, said Joanna Lambert, a wildlife ecologist at the University of Colorado Boulder. Of Colorado’s new population, one of the released wolves was killed by another wolf, whereas two were likely killed by mountain lions, according to Colorado Parks and Wildlife.  The changes that humans have made to the landscape only make it harder for these animals to survive. One of the animals, a male found dead in May, was likely killed by a car, state officials said. Another died after stepping into a coyote foothold trap. Two other wolves, meanwhile, were killed, ironically, by officials. Officials from CPW shot and killed one wolf — the offspring of a released individual — in Colorado, and the US Department of Agriculture killed another that traveled into Wyoming, after linking the wolves to livestock attacks. (An obscure USDA division called Wildlife Services kills hundreds of thousands, and sometimes millions, of wild animals a year that it deems dangerous to humans or industry, as my colleague Kenny Torella has reported.)  Yet, another wolf was killed after trekking into Wyoming, a state where it’s largely legal to kill them. Colorado Parks and Wildlife has, to its credit, tried hard to stop wolves from harming farm animals. The agency has hired livestock patrols called “range riders,” for example, to protect herds. But these solutions are imperfect, especially when the landscape is blanketed in ranchland. Wolves still kill sheep and cattle.  This same conflict — or the perception of it — is what has complicated other attempts to bring back predators, such as jaguars in Arizona and grizzly bears in Washington. And wolves are arguably even more contentious. “This was not ever going to be easy,” Lambert said of the reintroduction program.  Colorado is struggling to find more wolves to ship in  There’s another problem: Colorado doesn’t have access to more wolves.  The state is planning to release another 10 to 15 animals early next year. And initially, those wolves were going to come from Canada. But in October, the Trump administration told CPW that it can only import wolves from certain regions of the US. Brian Nesvik, director of the US Fish and Wildlife Service, a federal agency that oversees endangered species, said that a federal regulation governing Colorado’s gray wolf population doesn’t explicitly allow CPW to source wolves from Canada. (Environmental legal groups disagree with his claim). So Colorado turned to Washington state for wolves instead.  But that didn’t work either. Earlier this month, Washington state wildlife officials voted against exporting some of their wolves to Colorado. Washington has more than 200 gray wolves, but the most recent count showed a population decline. That’s one reason why officials were hesitant to support a plan that would further shrink the state’s wolf numbers, especially because there’s a chance they may die in Colorado.  Some other states home to gray wolves, such as Montana and Wyoming, have previously said they won’t give Colorado any of their animals for reasons that are not entirely clear. Nonetheless, Colorado is still preparing to release wolves this winter as it looks for alternative sources, according to CPW spokesperson Luke Perkins.  Ultimately, Lambert said, it’s going to take years to be able to say with any kind of certainty whether or not the reintroduction program was successful.  “This is a long game,” she said.  And despite the program’s challenges, there’s at least one reason to suspect it’s working: puppies. Over the summer, CPW shared footage from a trail camera of three wolf puppies stumbling over their giant paws, itching, and play-biting each other. CPW says there are now four litters in Colorado, a sign that the predators are settling in and making a home for themselves.

We’re working towards success.”

Selfies as William begins Brazil visit for environment prize

The prince has key environmental work planned with the Earthshot Prize and a speech at the COP30 summit - but started with a cable car trip up Sugarloaf Mountain.

As he came down again, he posed for selfies with several of the people who had waited to catch a glimpse of him.He is visiting Brazil for the first time with two key environmental missions. On Wednesday he is presenting the Earthshot Prize, the annual award from the charity he set up himself.The following day he will travel to Belem, in the Amazon rainforest, where he is scheduled to deliver a speech as part of COP30, the annual UN climate meeting where governments discuss how to limit and prepare for further climate change.PA MediaThe prince received the award of the keys to Rio from Mayor Eduardo Paes at a helipad platform on Sugarloaf Mountain...PA Media...but it is only a wider shot of the same moment that shows the majestic background of the city those symbolic keys represent.It is the first time that Prince William has travelled internationally for a COP summit, as his father, King Charles, has previously led the way for the royals, making several keynote speeches to world leaders over the years.Prince William did attend, along with his father, when it was held in Glasgow 2021, two weeks after the first Earthshot Prize.The prize annually awards a £1m grant in five different categories for projects that aim to repair the world's climate - and Prince William has committed himself to it for10 years, with Rio marking a halfway point for the venture.This year's shortlist includes an upcycled skyscraper in Sydney, the entire island of Barbados and a Bristol based company that filters microplastics from washing machines.When he announced the nominees, the prince spoke of the optimism and courage he was looking for."The people behind these projects are heroes of our time, so let us back them. Because, if we do, we can make the world cleaner, safer and full of opportunity - not only for future generations, but for the lives we want to lead now."PA MediaPrince William's first visit to Brazil was scheduled for five days to give him the chance to carry out other engagements before his more formal duties later in the weekAfter the ceremony, Mayor Paes said Prince William has been "amazed with the beauty of the city" and he joked: "So he's got the keys, he can do whatever he wants in the next 72 hours. The city belongs to Prince William. I'm still the king, but it will belong to him!"Prince William's visit to Rio de Janeiro is the most significant royal engagement he will make this year and also mark the first time he will be seen representing the Royal Family since the crisis surrounding his uncle Andrew.There has been speculation that Prince William was heavily involved in the King's announcement last week to sanction Andrew by removing his remaining titles and asking him to leave his home in Windsor - but those close to the situation say that was not the case. Although William would have had a powerful, influential voice as the future monarch, the decision was ultimately the King's working with his private team of advisers and in conjunction with the government.PA MediaCafu lined up 142 times for his national team and moved to Italy to play for Roma and AC Milan in the second half of his illustrious careerThe visit to Brazil will include the two key environment-based events but will also allow him to take in some of Rio's other famous sights.As an avid football fan and chairman of the English Football Association, it was no surprise that a pilgrimage was arranged on his first day to the Maracana Stadium, the stage of some of the football-mad nation's most famous moments.Once there, he was greeted by the player who wore the yellow and green kit more than any other, Brazil's most capped-star Cafu, who presented him with a signed number 2 Brazil shirt.The legendary right back, who is the only player in history to appear in three World Cup finals, was scheduled to join the prince leading training drills involving local children. Cafu has also agreed to be one of the star presenters of the Earthshot Prize, alongside former F1 driver Sebastian Vettel, Olympic gymnast Rebeca Andrade and Brazilian environmental activist Txai Suruí.
