From the United States Fish and Wildlife Service:
The wild population of Mexican wolves in the United States continued to grow in 2021. According to the 2021 annual count, the U.S. population of Mexican wolves has increased by 5 percent since the previous year, raising the total number of wolves in the wild to a minimum of 196 animals. This marks the sixth consecutive year of growth in the wild population.
From November 2021 through February 2022, the Interagency Field Team (IFT) conducted ground and aerial counts of Mexican wolves in Arizona and New Mexico. According to the IFT, the population is distributed with 112 wolves in New Mexico and 84 in Arizona. In 2020, the team documented a minimum of 186 wolves. The slower growth in 2021 is attributed to low pup recruitment in the wild population.
