Here’s a few of the many Michigan Black Bear Facts available from the DNR:

What is the status of black bear in Michigan?

Approximately 15,000 – 19,000 black bears (including cubs) roam the hardwood and conifer forests of northern Michigan. About 90 percent of the bear live in the Upper Peninsula, while the remaining ten percent are mainly found in the northern Lower Peninsula. However, it is becoming increasingly common to see bear in the southern half of the Lower Peninsula. During the past twenty-five years, the status of the Michigan black bear has been elevated from pest to prized game species. Today, Michigan’s only bear species is protected by law and managed by the Department of Natural Resources (DNR).

What are the physical characteristics of the black bear?

Most black bear in Michigan have dark black fur. Brown color variations are more common in western states. The size of a bear depends on its age, sex, diet, and season of the year. Adult female bear are generally smaller than adult males. In Michigan, female bear range from 100-250 pounds, while adult males weigh between 150-400 pounds. Adult black bear measure about three feet high when on all four feet and about five feet when standing upright. A bear is considered an “adult” when it is capable of reproducing, which generally occurs at three to four years of age in Michigan. In the wild, bear can live 20 to 30 years.

What is the home range of a black bear?

A bear’s home range is the area that provides sufficient food and cover for the animal to survive. Black bear are solitary animals, but family groups such as a sow and her cubs may be observed. Male black bear live in an area about 100 square miles in size, while females live in smaller areas of 10-20 square miles. Home range size is affected by food availability, the number of other bear in an area, and human development. As more people move to northern Michigan, the amount of undeveloped bear habitat declines.

What is the diet of the black bear?

In one word – everything. Black bear are considered opportunistic feeders, taking advantage of many seasonally available foods. Bear eat succulent, new green vegetation in the spring after they leave their dens. Colonial insects, such as ants and bees, may make up over half of their diet in late spring and early summer. Black bear experience rapid weight gain in years when wild berries, which are high in sugars and other carbohydrates, are available beginning in mid summer. Nuts and acorns, because they are high in fats and protein, are the best fall foods for bear when preparing for their winter’s sleep. If given the chance, black bear will supplement their natural diet with human garbage, pet foods, birdseed, or any foods placed to feed or attract other wildlife.
