From this story in the New York Times:
Federal officials have denied the state's request to hunt endangered gray wolves in response to the predators' increasing attacks on livestock and big-game herds. The state hoped to use a loophole in the federal Endangered Species Act and hold a "conservation hunt" for up to 186 wolves this fall. Daniel Ashe, United States Fish and Wildlife Service deputy director, denied the request on Thursday, saying that his agency supported sport hunting of wolves, but that it would not expect approval of Montana's proposal to survive a legal challenge. A federal judge in August restored wolves in Montana and Idaho to the endangered species list after a lawsuit from environmentalists.
