Did you know Yellowstone has partnered with Montana State University to study what grizzly bears eat? While meat is important to grizzlies, most of their diet consists of plants. In 1982, Yellowstone instituted Bear Management Areas (BMA) to restrict human access to areas thought to hold good food resources for grizzly bears. Today, biologists use GPS collars to assess when, where, and most importantly, what grizzlies are eating to ensure BMA's still encompass areas with good food resources.
