The Wisconsin DNR encourages the public to report any black bear den locations they find in Wisconsin. This is to help with an ongoing statewide study on black bear reproduction and population. The DNR’s bear den team has begun surveying dens for the season, but welcomes additional den reports. The Black Bear Litter and Diet Survey will generate new data within each bear management zone, which will improve the accuracy of population models. The public is encouraged to report as much information about occupied black bear dens as possible without approaching or disturbing the dens.
