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.
Habits & habitat. Wolves are found in North America, Europe, Asia and North Africa. They tend to live in the remote wilderness, though red wolves prefer to live in swamps, coastal prairies and forests.
