Jaguars Win Critical Habitat in U.S.

Jaguars, the third-largest cats after lions and tigers—and the biggest in the Western Hemisphere—used to live here. During the 18th and 19th centuries they were spotted in Arizona, New Mexico, California and Texas. Sometimes the cats roamed as far east as North Carolina and as far north as Colorado. As humans encroached on their territory, the endangered cats' range shifted south. Today it stretches from northern Argentina into Mexico's Sonoran Desert. But jaguars cross into the American Southwest frequently enough for some conservationists to argue that they deserve critical habitat protection. Now, after years of legal wrangling, the U.S. Fish and Wildlife Service (FWS) has agreed. In a  plan (pdf) published yesterday, the agency proposed designating 838,232 acres—an area larger than Rhode Island—as critical jaguar habitat. That means federal agencies cannot fund or authorize any activities that might "adversely modify" the earmarked land, which covers four stretches of mountain in southeastern Arizona, a section of the Peloncillo Mountains on the Arizona–New Mexico border, and a tiny piece of New Mexico's San Luis Mountains. It includes the site of a proposed copper mine in Arizona's Santa Rita Mountains, which will have to be carefully evaluated for its potential impact on jaguar habitat if the proposal is approved later this year, following a period of peer review, public comment (pdf) and economic analysis...more
