Successful Recovery Efforts Prompt Service Proposal to Delist Gray Wolf
Four decades of work by the U.S. Fish and Wildlife Service and its partners to protect and recover the gray wolf (Canis lupus) have successfully brought the species back from the brink of extinction in the western Great Lakes and Northern Rocky Mountains. As a result of these successful efforts to ensure that the gray wolf is no longer threatened with extinction as a species, the U.S. Fish and Wildlife Service has proposed to remove it from the list of threatened and endangered species throughout the United States and Mexico, while maintaining protection for the Mexican wolf (Canis lupus baileyi) in the Southwest.
The Service will continue federal protection and expand recovery efforts for the Mexican wolf in the Southwest by proposing to designate the Mexican wolf as an endangered subspecies under the Endangered Species Act and to modify existing regulations governing the nonessential experimental population. Outside of that recovery area, management and protection of wolves would be returned to state wildlife management agency professionals, following approved wolf management plans in states where wolves occur or are likely to occur in the future.
NOTE: The comment period on these proposals will open when the proposals publish in the Federal Register (scheduled the week of June 10). At that time, the Fish and Wildlife Service will publicly announce the opening of the comment period and provide instructions on this web page and through other channels.
