Michigan Requested Public Reports of Bear Dens

Live Poll

Should you report wildlife den locations to state authorities when you find them?

The Michigan Department of Natural Resources has asked residents to report the locations of black bear dens across the state. Biologists aim to evaluate these sites for potential inclusion in a long-term bear research study.

Why it matters

Identifying den locations allows researchers to study bear populations more effectively and gather critical biological data. This data helps state experts monitor the health and behavior of bears residing in Michigan.

Michigan has an estimated total population of 12,800 black bears, with 11,000 residing in the Upper Peninsula. Reports can be made by calling 906-202-3023 for the Upper Peninsula or 989-275-5151 for the Northern Lower Peninsula.

The players

Michigan Department of Natural Resources

This state agency is responsible for managing Michigan's natural resources and protecting the state's wildlife populations.

The details

Biologists visit reported dens to evaluate bears for research, where they sedate the animals to attach ear tags and collars. The team collects biological data and a nonfunctional tooth for DNA analysis before returning the bears to their dens undisturbed.

Black bears enter their winter dens during October and November.

Culture Shift

This effort follows a pattern established by the Michigan Department of Natural Resources bear research project to improve species management. It reflects a growing shift toward citizen-led wildlife monitoring in modern conservation efforts.

Residents in the Upper Peninsula and Northern Lower Peninsula should note that it remains illegal for the public to disturb a bear den. Those who spot a den should report the location to the Department of Natural Resources rather than approaching the site.

The takeaway

Public involvement helps state researchers gather necessary biological insights for bear conservation. Always prioritize safety and refrain from approaching dens if you encounter one in the wild.
