Gray Wolf. The gray or timber wolf's story is one of the most compelling tales of American wildlife. Once, the wolf was widespread across most of North America, but it was hunted ruthlessly and extirpated over most of its range. Today, the wolf is making a successful comeback in some of its former habitat due to strong conservation efforts.
The timber wolf (Canis lupus), also known as the gray wolf, was once prominent in the United States. The breed was hunted to near extinction, though, and has become the subject of conservation efforts. The U.S. Fish and Wildlife Service estimates 5,443 grey wolves inhabit the continental United States, using data from December 2012 and Spring 2013. An additional 7,700 to 11,200 timber wolves are believed to be in Alaska.
