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.
Subspecies of gray wolves in North America include the Arctic wolf (Canis lupus arctos), northwestern wolf (Canis lupus occidentalis), Great Plains wolf (Canis lupus nubilus), Mexican wolf(Canis lupus baileyi) and the eastern timber wolf (Canis lupus lycaon), which is debated by some as a distinct species, the eastern wolf (Canis lycaon).
