Wolf Territories

The map below depicts gray wolf territories for Wisconsin in 2011. A PDF map and report listing all verified wolf threats and depredations for 2010 & 2011, including livestock are available below.

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.

Wolf Depredations and Threats

Reports & Maps

In 2010, wolf depredation to livestock occurred on 47 farms. Total livestock depredation in 2010 included: 63 cattle killed (47 calves), 5 cattle injured, 6 sheep killed (4 lambs), 1 goat injured, and 6 farm deer killed. A total of 25 to 27 packs and 2 to 4 loners/dispersers were involved in depredation on livestock. The enclosed map shows locations of all depredations on livestock (injured or killed), and verified threats or harassment of livestock. For the purpose of depredation management, game farm deer are considered livestock. Non-livestock depredation include attacks on pets, and human safety situations with wolves.
