MADISON, Wis. (WRN) — Help the Wisconsin Department of Natural Resources track the state’s black bear population.

The DNR is asking for the public to report any black bear den locations as part of an ongoing statewide study on black bear reproduction and population. The survey will improve the accuracy of population models, as well as help researchers as they investigate a connection between consumption of human food and bear reproduction.

If you come across a black bear den, note its GPS coordinates, take a photo from a safe distance, and describe the site and surrounding area. More info can be found on the DNR’s website.
