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.
Wolves once ranged over almost all of North America north of Mexico City, except possibly parts of California. Extirpation of gray and red wolf populations began shortly after European settlement. In the United States the range, population and legal status of wolves varies by state and region.olves once ranged over almost all of North America north of Mexico City, except possibly parts of California.
