Endangered Mexican gray wolves are making more strides, as more breeding pairs and pups have been documented since reintroduction efforts began in the southwestern U.S. more than two decades ago, federal wildlife managers said Tuesday.
Since the first wolf release in 1998, the program has had its share of fits and starts due to illegal killings, a lack of genetic diversity and legal wrangling over management. The rarest subspecies of gray wolf in North America, Mexican wolves were listed as endangered in the 1970s and a U.S.-Mexico captive breeding program was started with the seven remaining wolves in existence.
“By every possible measure, progress was made," he said, pointing to 31 breeding pairs that produced 121 pups, about two-thirds of which survived to the time of the count. The survival rate for pups in their first year is typically around 50%.
