There is ample evidence to support the delisting of the gray wolf Canis lupus from the Endangered Species Act. In 2009, the U.S. Fish and Wildlife Service (USFWS) published a rule in the Federal Register to delist the species in a portion of North American states. The rule reports that a healthy, distinct population segment of the gray wolf within the Northern Rocky Mountains (NRM) supports the revision of the gray wolf’s listing in the states that the NRM encompasses (Washington State, Oregon, Utah, and Idaho) except Wyoming (FWS 2009).
