“For us, for the people in this room, wolves are not some romanticized concept. ... For those of us on the ground, they’re a very real daily threat,” said Tom Paterson, a rancher and president-elect of the New Mexico Cattle Growers’ Association. He’s worried about his grandson playing on the deck, just 100 yards (90 meters) from where wolves killed a steer in February.County commissioners issued a warning to residents last week to be aware of their surroundings when outdoors and maintain constant supervision of children and pets.

The concerns stretch beyond New Mexico, as officials in parts of Oregon and Northern California say gray wolves — the larger, more common cousins of Mexican gray wolves — seem brazen and are killing more livestock. Two California counties declared emergencies in recent weeks and the sheriff in another requested help from state wildlife officials.Ranchers in New Mexico and Arizona have been at odds with the reintroduction of Mexican gray wolves since the first release in the late 1990s. Despite limited programs for reimbursing certain losses, ranchers say wolves pose a threat to their way of life, which is already challenged by prolonged drought and rising prices.Environmentalists argue that Mexican wolves should have a place in the Southwest, often criticizing the U.S. Fish and Wildlife Service for not releasing more captive wolves to ensure genetic diversity among the wild population. They contend there’s no incident in recorded history of a Mexican wolf attacking or injuring a person.

While fatal attacks are rare in North America, Catron County Sheriff Keith Hughes said there’s danger in not removing Mexican wolves that frequent developed areas. He said one was spotted Wednesday in the community of Reserve.There are at least 286 Mexican wolves in Arizona and New Mexico, but federal officials acknowledged Thursday that they don’t know how many actually are on the landscape. They also say livestock kills are decreasing, with 100 confirmed in 2024. Ranchers argue that for every confirmed kill, there are likely five more where investigators don’t have enough evidence left to add them to the list or the animals are never found.

Wildlife managers conducted 290 successful hazing operations last year to scare wolves away from rural homes and livestock, and the Fish and Wildlife Service reiterated its commitment Thursday to minimizing conflicts and reducing the economic effects on ranchers.

In the resolution, Catron County states the culture and customs of residents have been compromised by the reintroduction of Mexican wolves. It requests emergency financial aid from the state and asks the governor to order the New Mexico National Guard into service to support county authorities as needed.Pisano is recovering well, the NYU team announced Wednesday. She’s only the second patient ever to receive a pig kidney -- following a landmark transplant

– and the latest in a string of attempts to make animal-to-human transplantation a reality.This week, the 54-year-old grasped a walker and took her first few steps.

“I was at the end of my rope,” Pisano told The Associated Press. “I just took a chance. And you know, worst case scenario, if it didn’t work for me, it might have worked for someone else and it could have helped the next person.”Dr. Robert Montgomery, director of NYU Langone Transplant Institute, recounted cheers in the operating room as the organ immediately started making urine.
