They utilize science, legal action, and creative media to combat extinction and promote a sustainable future for all species. Learn more at biologicaldiversity.org.

Once abundant in Eastern North America, red wolves now have only one wild population left in North Carolina's Albemarle Peninsula, which had 22 individuals before several litters were born in 2026. To ensure their survival, additional populations are urgently needed.

The Center for Biological Diversity is a nonprofit organization based in Tucson, Arizona. We believe that human welfare is closely tied to nature and the diversity of wild animals and plants. Our mission is to secure a future for all species at risk of extinction, as their loss diminishes society.

Border-wall construction is threatening the movement corridor for jaguars and other wildlife along the U.S.-Mexico border. Recent remote camera footage has captured Cinco, a male jaguar first documented in late 2025 by University of Arizona researchers after crossing from Mexico. Russ McSpadden from the Center for Biological Diversity emphasizes that each sighting of Cinco highlights the urgent need for jaguars to move freely between the two countries, as the border wall poses a significant threat to their survival in Arizona.

Wyoming's wolf-hunting season opens this September, threatening the life of Yellowstone's oldest living wolf, 1090F, and her family. Mollie's pack, the last remaining from Yellowstone's historic wolf reintroduction, has significantly contributed to scientific understanding of wolves.

These wolves deserve protection, not unnecessary death. You can help by urging the Wyoming Game and Fish Commission to close Hunt Area 1 to wolf hunting. Take action at the link in our bio.

Gopher tortoises are critically endangered, yet federal wildlife officials deny them protections under the Endangered Species Act across most of their range. The Center for Biological Diversity has filed a lawsuit to challenge this decision, bolstered by new research advocating for their protection.

These tortoises are keystone species, with their burrows supporting over 360 other species. Unfortunately, habitat destruction has reduced their longleaf pine habitat to less than 3% of its original size, leading to an 80% population decline over the past 120 years.

Meet the Cacti, a native species of the Mojave Desert, where a data center is proposed on public land. This fragile ecosystem supports wildlife, including desert tortoises and various desert species.

The planned data center in southern Nevada threatens to industrialize public lands, strain Colorado River Basin water resources, and disrupt habitats that have existed for generations. Public lands should serve wildlife, people, and the desert, not accommodate industrial development.

Red wolves in North Carolina have welcomed four litters of pups, with 16 surviving their first few months. This new generation offers hope for the future of red wolves, whose population currently consists of only 22 adults.

The Trump administration is considering a data center in southern Nevada, the first on public land, approved without public input or environmental review. Boulder City residents are concerned about potential air quality degradation, wildlife habitat destruction, and increased water consumption in the drought-stricken Colorado River Basin.

This project could set a troubling precedent for future developments on public lands. The Center for Biological Diversity has filed an appeal against this development and urges you to take action. Demand that the Trump administration halt permits for data centers on public lands, which should be preserved for wildlife and recreation, not exploited by Big Tech. Take action here.

A proposed data center in Southern Nevada could be the first built on public land, approved without public notification, involvement, or environmental review.

This project threatens precious water resources in the drought-stricken Colorado River Basin, harms wildlife habitat, and worsens air pollution. If approved, it may set a precedent for more data centers on public lands nationwide.

Public lands should be preserved for wildlife, biodiversity, and future generations, not exploited for corporate profit. The Center for Biological Diversity plans to appeal this development. Support our efforts to protect public lands by donating at this link.

BREAKING: Our attorneys at @centerforbiodiv have filed an emergency injunction to prevent SpaceX from privatizing 727 acres of the Lower Rio Grande Valley National Wildlife Refuge.

South Texas has limited public land, with only 5 percent of native habitat remaining in the Rio Grande Valley, and even less is publicly accessible. The local communities, wildlife, and Indigenous nations should not have to sacrifice more land for the profit of one of the wealthiest corporations.

Stay tuned and follow us for updates on this ongoing public lands fight.

The Center for Biological Diversity is taking legal action against the Trump administration for attempting to weaken crucial habitat protections under the Endangered Species Act. Without these protections, endangered species face increased risks of extinction, as the administration downplays the impact of habitat destruction on wildlife.

The Trump administration's changes to the Endangered Species Act have removed crucial habitat protections for endangered wildlife by redefining "harm" and rescinding the blanket rule that offered equal protections for threatened species. This rule, which prohibited actions that could kill or injure these species or destroy their habitats, was initially repealed in 2019 and reinstated in 2024.

We need your voice to urge Congress to restore these essential protections. This fight extends beyond endangered wildlife; it encompasses the environmental laws that safeguard us all. Habitat destruction is the leading cause of extinction, and we cannot save species without protecting their homes. At the Center, we are committed to defending our environmental laws and will not back down.

Endangered species need habitats to survive, yet the Trump administration has weakened protections under the Endangered Species Act by removing the definition of "harm." This change threatens the survival of over 1,000 species, including wolves, grizzly bears, and bald eagles.

The Center for Biological Diversity is fighting this decision in court to protect the Act and the species it supports. Without these protections, activities like logging and mining could more easily invade the last homes of vulnerable wildlife.

We are suing the Trump administration for attempting to weaken crucial habitat protections under the Endangered Species Act. Without these protections, endangered species face increased risks of extinction.

The administration's claims that habitat destruction does not harm wildlife, such as spotted owls and whooping cranes, are misleading and ignore scientific evidence. We have successfully defended this law in the past and are prepared to do so again. Join us at the link in our bio.

The Trump administration has significantly weakened the Endangered Species Act, posing a severe threat to already vulnerable species. Habitat destruction, the primary cause of extinction, is exacerbated by the removal of these vital protections, which have historically preserved forests, rivers, and essential habitats for wildlife.

This rollback paves the way for increased logging, mining, and drilling in critical areas for endangered species. The Center for Biological Diversity is committed to challenging this decision in court, advocating for the protection of wildlife and natural ecosystems for future generations.
