Albuquerque, New Mexico (AP) – Twenty-two captured Mexican wolf puppies were placed in wild burrows in the southwestern United States and bred by surrogate packs, the US Fish and Wildlife Service announced on Monday.

The agency called this year’s crossbreeding season a success and said endangered predators who have participated in foster parent programs over the past six years have helped increase the genetic diversity of wild populations. New Mexico And Arizona.

Over the past two months, nine puppies have been raised in three different herds in eastern Arizona, and 13 have been placed in five herds in western New Mexico, officials said. Last year, 20 puppies. Was put into a wild burrow.

Jim Devos, coordinator of the Mexican wolf in the Arizona Game Fish division, said in a statement that the breeding program is based on a partnership with a private sector that is part of a national capture and breeding activity. ..

The captive puppies came from littermates at facilities in New Mexico, Texas, and Missouri.

“Without this important partnership, gene recovery is essentially impossible,” he said. “Importantly, we are now seeing raised Mexican wolves giving birth to themselves.”

Mating is the placement of puppies <14 days old from captive breeding populations into wild burrows and raising puppies of similar age as wild wolves. According to authorities, the survival rate of crossbred puppies is about 50% of that of wild-born puppies and the first year of life.

According to the wolf recovery team, at least 12 of the wolves raised over the years have survived in the wild. Seven of these wolves reached the breeding season, after which four gave birth in the wild.

Authorities said the puppies were too young to record their time of care, so they were more likely to survive because they could confirm that only the recaptured puppies were alive.

Some environmentalists questioned these numbers and said that crossbreeding was not enough to get the species on track for recovery. The Center for Biodiversity told wildlife managers. We are asking you to release a breeding pair with your puppy as a protected family pack.

Biodiversity Center of America Michael Robinson suggested that captive, well-cohesive, wild-fed herds had lower mortality and disappearance rates than crossbred offspring. He also expressed concern about the illegal killing, noting that the fate of many of the 50 puppies housed in the wild between 2016 and 2020 is unknown.

“Apart from the short-term sick hybrid offspring (of the Fish and Wildlife Service), no matter how they are released, unless they deal with the illegal killings (of the Fish and Wildlife Service). It will cast a shadow over the genetic protection of the released wolves. “

A recent study of Mexican wolves found that at least 186 wolves were distributed between New Mexico and Arizona. Over the last five years, wild populations have almost doubled.

Meanwhile, ranchers in the recovery area say they continue to see more livestock killed by wolves, despite efforts to scare them. They have voiced against the following wolf releases: Planned At Ted Turner Ranch in southwestern New Mexico.
