A Divide as Wolves Rebound in a Changing West Sheltered for many years by federal species protection law, the gray wolves of the West are about to step out onto the high wire of life in the real world, when their status as endangered animals formally comes to an end early this year. The so-called delisting is scheduled to begin in late March, almost five years later than federal wildlife managers first proposed, mainly because of human tussles here in Wyoming over the politics of managing the wolves. Now changes during that time are likely to make the transition even more complicated. As the federal government and the State of Wyoming sparred in court over whether Wyoming’s hard-edged management plan was really a recipe for wolf eradication, as some critics said, the wolf population soared. (The reworked plan was approved by the federal government in November.) During that period, many parts of the human West were changing, too. Where unsentimental rancher attitudes — that wolves were unwelcome predators, threatening the cattle economy — once prevailed, thousands of newcomers have moved in, buying up homesteads as rural retreats, especially near Yellowstone National Park, where the wolves began their recovery in 1995 and from which they have spread far and wide. The result is that there are far more wolves to manage today than there once would have been five years ago — which could mean, biologists say, more killing of wolves just to keep the population in check. And that blood-letting might not be quite as popular as it once was....
