Tell Congress: Stop the Border-Wall Assault

The Trump administration is moving fast along the southern border — bulldozing walls, roads, and other infrastructure through some of the United States' most spectacular and ecologically important landscapes.

In Big Bend National Park, Texas, the administration just broke ground and may soon blast canyon walls and block public access to the Rio Grande. In California it's building border barriers in the San Diego borderlands, endangering Tecate Peak, a sacred mountain for the Kumeyaay people. In Arizona multiple wall projects threaten the Tohono O’odham Nation; critical migration corridors for wild cats and other species in the San Rafael Valley; and Quitobaquito Springs, a desert oasis in Organ Pipe Cactus National Monument home to critically endangered Sonoyta mud turtles and Quitobaquito pupfish. And in New Mexico border construction is sucking up precious groundwater.

U.S. environmental and cultural-protection laws should safeguard the wild — but the Trump administration has waived many of them to limit environmental review, accountability, and public participation for its border-wall projects.

Congress has the power to shut down this border-wall blitz. Tell your legislators to step in immediately.

Suit Takes on Arizona Sport-Hunts of Puma Kittens

Sport hunters killed almost 2,000 mountain lions in Arizona from 2018 to 2024. Among those killed 54% were kittens under a year old or juveniles under 2. On top of that, 41% were females — and killing more than 20% of adult females can sharply reduce lion populations.

So last week the Center for Biological Diversity sued the Arizona Game and Fish Department and Commission challenging their lion quotas as unsustainable. We asked the court to stop issuing sport-hunting permits for them until the population recovers. Puma-hunting season begins Aug. 21.

“Arizona’s state-sanctioned killing of kittens and juvenile mountain lions is beyond cruel,” said Robin Silver, one of the Center’s cofounders. “It’s time to end this slaughter and ensure mountain lions continue to roam the wilds of Arizona in the future.”

Greater Sage Grouse Need Your Help

The U.S. Bureau of Land Management and utility company NV Energy are trying to ram a 235-mile transmission line called Greenlink North through central Nevada — mostly to power data centers.

The project will spell disaster for greater sage grouse if it bulldozes some of the best sagebrush habitat around — and the BLM is pushing that by creating massive exemptions to rules protecting the species. These beloved birds need intact sagebrush for their “leks,” or mating grounds, where they congregate each spring to enchant the world with their mesmerizing mating dances. Sadly those leks are becoming less and less lively as the birds’ habitat dwindles due to development, off-road vehicles, and other threats.

Tell the feds to reject Greenlink North and find a less harmful route for a transmission line. Greater sage grouse depend on it.

New Jaguar Videos Out of Arizona

As border-wall construction infringes more and more on a critical movement corridor for jaguars and other creatures of the U.S.-Mexico border, our remote cameras north of the San Rafael Valley have captured new footage of the male jaguar nicknamed Cinco.

After moving across the border from Mexico, he was first documented in the region by University of Arizona researchers in late 2025.

“Each new video of Cinco is a glaring reminder that jaguars need to move freely between U.S. and Mexico and that Trump’s border wall is a deadly threat to their continued existence in Arizona,” said the Center’s Russ McSpadden.

In 2022 the Center petitioned the U.S. Fish and Wildlife Service to reintroduce jaguars in Arizona and New Mexico.

Animation: Where Red Wolves Once Roamed

Red wolves once lived throughout the eastern half of the United States, from the Southeast to Texas and parts of the Midwest. But they were driven to near-extinction, and now, living wild only on a coastal peninsula in North Carolina, they’re the most endangered canines in the world — and the subject of an inspiring new Center campaign.

On the occasion of International Wolf Day, check out our new animation of red wolves’ historic range.

The Revelator: Tea and Salamanders

The hills of Darjeeling hold more than world-famous tea gardens. They’re also home to ancient Himalayan salamanders — known locally as pani kukur or “water dogs” — and the people working to save them from disappearing.

That’s Wild: 8,000 Newly Discovered Species

It’s not too rare to hear about a new species being described, but 8,000 of them in one blow?

Researchers working on Ecuador’s Chocó Andino region just announced the genetic ID’ing of 8,000 species of insects who have yet to be described. The specimens, mostly flies, wasps, and butterflies, were gathered in a protected area that was named a World Biosphere Reserve eight years ago and is a hotspot of both biodiversity and environmental resistance to destructive activities like mining.
