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 most common wolf is the Gray Wolf, or called he American Timber Wolf, as we know it. It's found in most of Canada, but Minnesota Zoo has let some free in Amethyst Mountain â¦ , Yellowstone National Park and Slough Creek, Yellowstone National Park to save them from extinction of the species.
