From an MDNR news release
Be alert for black bear dens this winter and if one or more are sighted the Michigan Department of Natural Resources asks residents to report those locations to the agency.
“Finding winter den locations is an important component to managing black bear populations, and we need hunter, trapper and landowner assistance to add new den sites to the program in the Upper Peninsula and northern Lower Peninsula,” Mark Boersen, wildlife biologist at the DNR Roscommon Customer Service Center, said.
He added that six bears are currently being monitored using radio tracking equipment on the ground and in aircraft.
According to the MDNR, bears usually enter dens in November and December, depending on where in the state they’re located. Den locations offer shelter from the elements and vary widely. Some include areas with dense vegetation. Other sites include rock crevices, fallen trees or excavated holes.
A news release from the agency stated: “Bear dens may look like brush piles covered in snow or excavated holes in the ground, both having an icy opening to vent fresh air.”
Don’t approach a bear den
The MDNR offers the following suggestions to those spotting a bear den or dens.
If you’re in the vicinity of a potential den site, stay quiet and listen for any sounds coming from within. You may be able to hear cubs nursing or crying.
If you believe you have found a bear den, keep a safe distance away and avoid disturbing the den or the bears inside. Remember: It is illegal to disturb a bear’s den or a bear in its den.
Record the location, using GPS coordinates if possible, and report the information to one of the following DNR staffers:
- Upper Peninsula: Cody Norton at 906-202-3023 or NortonC3@Michigan.gov.
- Northern Lower Peninsula: Mark Boersen at 989-275-5151 or BoersenM@Michigan.gov.
DNR biologists will determine if the denned animal is a candidate for joining the agency’s project. If it is, the bear will be sedated and its sex, weight, body measurements and reproductive history will be collected. A small tooth, which serves no function, will be removed to determine the bear’s age and also retrieve a DNA sample. The bear will receive ear tags and be fitted with a collar before being returned to its den. See a short video of this bear examination process.
