The Mexican gray wolf breeding program is managed for the U.S. Fish & Wildlife Service (USFWS) by the Association of Zoos and Aquariums' Mexican Gray Wolf Species Survival Plan.
Mexican gray wolves are the rarest and most genetically distinct subspecies of North American gray wolves. If not for the recovery program, they would likely be extinct in wild.
The US Fish & Wildlife Service first listed the Mexican gray wolves on the Endangered Species List in 1976. Currently 248 wolves live in 55 institutions in the US and Mexico.
As of 2014, 110 wolves are living in the wild in Apache and Gila National Forests in Arizona and New Mexico as a part of reintroduction program.
