Winter wolf survey results indicate healthy population

The Wisconsin DNR has announced that the 2021-22 overwinter number of pack-associated wolves, is estimated between 812 and 1,193 within the pack-occupied range, with the most likely estimate of 972 wolves in a number of packs estimated to be between 243 and 352 packs, with a most likely value of 288 packs.

While the wolf population estimate is lower than the previous winter, the current population remains nearly as large and widespread as it has been in recent years. The observed decline does not indicate a wolf population in biological jeopardy.

Multiple population indicators point toward a healthy, secure wolf population in Wisconsin. The distribution of wolves and the estimated number of packs in the state, was similar to past years. The average home range size of wolves this year, was estimated at 66 square miles, which is also similar to recent years.

The winter tracking surveys did show a decrease in average pack size in all zones from the previous winter. This decrease is consistent with observations, following previous wolf hunting and trapping seasons in Wisconsin.

The DNR uses data from multiple sources to monitor wolves in Wisconsin. These science-based techniques include winter snow tracking surveys, GPS-collared wolves, assessment of mortalities and public observation reports. The data collected annually, is a result of a significant amount of on-the-ground monitoring, which the department will continue, as it is a critical part of maintaining a sustainable population into the future.

A draft of the updated wolf management plan is in the works. A public review and comment period will follow release, once it is available.

The public is encouraged to check the DNR’s wolf management plan webpage for the most recent information on the plan. The draft plan is anticipated to be ready for public review this fall.
