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 gray wolf (Canis lupus) is a native species that was likely extirpated from California in the 1920s, and from most of its range in the United States by the mid-1930s. A small population began naturally recolonizing northwestern Montana, reaching about 65 wolves by 1994.
