The Gray Wolf (Timber Wolf) in Wisconsin

The sound of a howling gray wolf is becoming a more common event in Wisconsin. A growing population of wolves now live in Wisconsin, one of about a dozen states in the country where gray wolves exist in the wild. Gray Wolves, also referred to as Timber Wolves, are the largest wild members of the dog family.

Wolves are social animals, living in a family group, or pack. A wolf pack's territory may cover 20-120 square miles, about one tenth the size of an average Wisconsin county. This species has been state delisted since 2004 and has been listed as a "Protected Wild Animal" by the Wisconsin DNR U.S. Fish and Wildlife Service. They have also been federally delisted since March 12, 2007, with no current federal designation.
