More diverse gene pool key to wolves

Last month, the U.S. Fish and Wildlife Service shot the last captive-born Mexican gray wolf in the wild for “escalating nuisance behavior” after it came too close to Catron County neighborhoods. It was a fairly routine kill, but the take of Mexican gray wolf No. 1130 marked a shift in the program to recuperate the endangered species: Today all 110 wolves roaming the wild of eastern Arizona and southwestern New Mexico were born in the wild. On the surface, that sounds like a milestone. Just crossing the 100 mark for wild wolves sounds significant, especially for a program that began with just seven known wolves left in the species. The authors of the original 1982 Mexican gray wolf recovery plan – which badly needs an update – set 100 as a goal but could hardly imagine ever reaching such numbers. Shouldn’t wolf advocates be celebrating, then? Shouldn’t ranchers, many of whom oppose the reintroduction of a top predator, be able to say enough is enough? New Mexico Game Commissioner Ralph Ramos posed a question to the federal Fish and Wildlife Service at a recent commission meeting in Farmington. With more than 100 wolves successfully reproducing and surviving in the wild, he asked, “Why don’t we support their natural breeding? Why do we want to keep adding more?” Here’s why: Because the Mexican gray wolf population isn’t nearly as strong as its numbers suggest. Maggie Dwire, the Fish and Wildlife Service’s assistant wolf recovery coordinator, said most of the animals in the wild are related to one another – too closely related to ensure the survival of the species, the goal of the reintroduction program...more
