Wisconsin’s gray wolf record reads like a map of the north woods. Of 193 records, Burnett County holds 27 and Bayfield 15, with Oneida, Vilas, and Ashland stacked through the northern tier and a second cluster in the central forest around Juneau and Jackson counties.

The recovery that needed no release trucks

Wisconsin’s wolves came back the old way, on foot. As Minnesota’s protected population grew, dispersers began crossing the St. Croix and the upper Mississippi in the mid-1970s, and the first new packs denned in the northwest. From there they spread through the big public forests, the country of the Chequamegon-Nicolet National Forest, Northern Highland State Forest, and Crex Meadows Wildlife Area, and eventually into the sandy central forest. Recent winter counts put the state near a thousand wolves, one of the strongest recoveries anywhere in the species’ range. For all that, wolves keep to themselves: most people who live, hunt, and hike in Wisconsin wolf country have never laid eyes on one.

June pups, November travelers

The calendar has two humps, June with 30 records and November with 21, and both make wolf sense. Spring pups leave the den for rendezvous sites as summer opens, and pack activity around those sites runs high; by November the year’s young wolves are traveling with the pack, some are striking out on their own, and early snow writes their routes across the north woods.

Status in Wisconsin

NatureServe ranks the gray wolf S4, Apparently Secure, in Wisconsin, and the species is native to the state. USGS NAS does not list it as nonindigenous here.
