Mexican Wolf Recovery    

The Mexican wolf is the rarest subspecies of gray wolf in North America. Once common throughout portions of the southwestern United States, the Mexican wolf was all but eliminated from the wild by the 1970s. In 1977, the U.S. Fish and Wildlife Service initiated efforts to conserve the species. In 1998, Mexican wolves were released to the wild for the first time in the Blue Range Wolf Recovery Area within the Mexican Wolf Experimental Population Area. Missing from the landscape for more than 30 years, the howl of the Mexican wolf can once again be heard in the mountains of the southwestern United States.

Wild Population of Mexican Wolves Grows for Fifth Consecutive Year

March 2021
The wild population of Mexican wolves in the United States saw its fifth consecutive year of growth in 2020. According to the recent count, the U.S. population of Mexican wolves has increased by 14% since last year, raising the total number of wolves in the wild to a minimum of 186 animals.

From November 2020 through January 2021, the Interagency Field Team (IFT) conducted ground counts in Arizona and New Mexico that concluded with aerial counts of Mexican wolves in January and February. According to the IFT, the 186 wolves are distributed with 114 in New Mexico and 72 in Arizona. In 2019, the team documented a minimum of 163 wolves, which was a 24% increase from 2018. This population has nearly doubled in size over the last five years.
