Gray Wolf Distribution Map

The map below depicts gray wolf territories for Wisconsin in 2009. Visit the Aquatic and Terrestrial Resources Inventory WebMapping Demonstration Site (exit DNR) for a dynamic map that will allow you to zoom in on a particular pack for more information.

Wolf Territories determined by radio tracking: These represent the outer boundaries or polygon of radio location points obtained on one or more radiocollared pack members, usually from mid April through mid April. Most territories were determined from 20 to 50 radio locations obtained by aerial radio telemetry. Isolated radio locations of >5km (>3.1 miles) from other locations were assumed to be extra-territorial moves, and were not included with the designation of the territory boundary of the pack.

Approximate Wolf Territories: These represent approximate territory boundaries based on observations of field sign, (scats, tracks, urinations, kills, beds, howls and sometimes dens), as well as agency and public reports of wolf observations. These territories represent areas of similar size and habitat conditions observed in radio tracked packs.
