MADISON, Wis. (WRN) — You can help the Wisconsin Department of Natural Resources with its black bear studies.

The DNR is asking you to report any black bear den locations you might come across. The Black Bear Litter and Diet Survey will generate new estimates of black bear reproductive rates within each of the state’s bear management zones.

DNR investigators are also using the study to investigate a connection between consumption of human food sources and bear reproduction.

If you think you’ve come across a bear den you should log its GPS coordinates, take photos, and describe the site and any signs of bear activity. More info can be found on the DNR’s website.
