Tell Congress to Oppose Efforts to Derail Mexican Wolf Recovery

Mexican Wolf Family

On Wednesday, September 3, 2025, the House Natural Resources Water, Wildlife, and Fisheries Subcommittee will consider a bill that would prematurely remove Endangered Species Act protections for Mexican gray wolves, the most genetically distinct subspecies of gray wolf in the United States and one of the most imperiled wolves in the world.

H.R. 4255, misleadingly named the “Enhancing Safety for Animals Act of 2025”, would threaten the safety of Mexican gray wolves. The bill relies on incorrect data and blatant misinformation when making the claim that Mexican gray wolves have met recovery criteria. They have not yet recovered.

Oppose Anti-Wildlife Riders in Final FY2026 Interior Appropriations Bill

Dear [Decision Maker],

I urge you to oppose H.R. 4255, which would remove Mexican gray wolves from the federal threatened and endangered species list and set in motion their path to extinction. Just 286 Mexican gray wolves live in the United States, with fewer than 24 in Mexico, and they face continued threats from poaching and high levels of inbreeding.

Independent scientists say the U.S. needs to have at least 750 Mexican wolves in three connected subpopulations to be truly recovered. If H.R. 4255 passes, Mexican gray wolves will prematurely lose the protections they so desperately need.



The Endangered Species Act is a landmark piece of legislation that institutionalized our national commitment to conservation, science-backed recovery plans, and the protection of imperiled species. A recent survey found that support for the ESA has remained consistently high over the last three decades, at about 84%, and support is consistent among people living in urban, suburban, and rural environments.

Science, not politics, should determine endangered species recovery.

Please reject this legislation and support Mexican gray wolf recovery efforts that are rooted in the best available science.

Sincerely,
