Growth slows for endangered Mexican gray wolf population

ALBUQUERQUE, N.M. (AP) — There are now more Mexican gray wolves roaming the southwestern U.S. than at any time since the federal government started to reintroduce the endangered species, wildlife managers said Wednesday.

The results of the latest annual survey of the wolves show there are at least 196 in the wild in New Mexico and Arizona — the sixth straight year that wolf population has increased.

But officials with the U.S. Fish and Wildlife Service said the population's growth in 2021 was tempered by higher than average pup mortality. Life was made more difficult for the wolves because of a persistent drought that has resulted in low precipitation and scant snowpack, the officials said.

Fewer than 40% of pups survived through the end of the year, though more breeding pairs were recorded in 2021.

“We are happy to see the wild population of Mexican wolves continue to grow year after year,” said Brady McGee, coordinator of the Mexican gray wolf recovery program. “The service and our partners remain focused on recovery through improving the genetic health of the wild population and reducing threats, while also working to minimize conflicts with livestock.”

Ranchers continue to have concerns about livestock killed by the wolves, saying efforts to scare the predators away from livestock — by horse riders, nonlethal shots fired from guns and flags put up on fences near cattle — have not been effective enough. Feeding caches for the wolves loaded with elk meat or road kill are also set up by officials to lure wolves away from livestock.

Unlike wolf reintroductions in Yellowstone National Park and elsewhere in the northern U.S., wildlife managers in the Southwest must deal with a climate that has encouraged a year-round livestock calving season, meaning wolves can prey on...
