Wisconsin DNR says bear den survey in full swing

Den survey season is in full swing, and the DNR’s bear research team is still searching for publicly reported den locations. If you’re outdoors this winter and hear a frequent squeaking, humming or sucking sound, be sure to take note because it could be denning cubs!

Den location reports play a vital role in the data collection efforts for the ongoing Black Bear Litter and Diet Survey, which aims to improve the accuracy of state population models and inform bear management decisions across the state.  

If you suspect the location of an active den and would like to report it to the DNR, please maintain a safe distance of at least 30 yards and then follow these steps: 

  1. Take note of your surroundings. Are there any visible tracks, scratch marks on trees, scat or damaged vegetation nearby? Have there been recent bear sightings in the area? Do you hear any noises coming from the den? 
  2. Drop a pin in your phone to record the GPS coordinates of your location. If this is not possible, try to remember a detailed description of where you were on the property in question.  
  3. If you have a camera or phone with a camera function, take a photo where the den is visible.  
  4. Learn more about the study and submit your den location report to us online.

Please note that due to staffing capacity, the bear research team may not be able to contact you about your report; reports with information suggesting the den is active will be prioritized to meet research study requirements.
