Mexican gray wolves, also known as lobos, are a highly endangered subspecies. The Center for Biological Diversity, a 501c3 nonprofit, spearheaded their reintroduction to Arizona’s Apache National Forest in 1998. Since then, we have worked tirelessly to protect these unique wolves from persecution and boost their declining genetic diversity.

Today, 241 lobos roam wild in Arizona and New Mexico, with 380 in captive-breeding programs. Despite this progress, they remain among North America’s most endangered mammals. We are committed to their full recovery, believing that human welfare is deeply linked to the vast diversity of wild animals and plants.

The Center has filed a notice of intent to sue the U.S. Fish and Wildlife Service (FWS) for refusing to develop a national gray wolf recovery plan under the Endangered Species Act (ESA). This challenges the Trump administration's finding that ESA protection for the gray wolf is "no longer appropriate" and its decision to forgo an updated recovery plan. This action comes two years after a similar successful lawsuit.

Collette Adkins, a senior attorney, affirmed, "We’re challenging the Trump administration’s unlawful decision to once again abandon wolf recovery, and we’ll win." She stressed that the FWS must follow science and law, demanding a comprehensive national recovery plan. Past delistings resulted in hundreds of wolves being hunted, underscoring the critical need for consistent federal protections.
