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.
Gray wolves can survive in many biomes as long as food is plentiful and the climate is relatively cold. The Siberian Taiga, one of the habitats they are best suited to, is a boreal forest with long, cold winters and short summers.n Canada and Alaska, the gray wolf population is stable. In most of North America, however, they are an endangered species. In Europe, Asia, and Africa, the remaining wolf populations are tiny. The largest wolf population in Europe and Asia is found in Russia, which includes the Siberian Taiga.
