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.
Packs of gray wolves maintain home ranges which vary in size. In open habitats, such as tundra, they may range over 13,000 square kilometers. In forested areas the home range may be only 130-1300 square kilometers. During a day gray wolves may travel as much as 75 kilometers.
