Both black bears and grizzly bears are commonly found in the Rocky Mountains.

In the Rocky Mountains, black bears and grizzly bears are the two prevalent bear species. Black bears are more widespread, inhabiting forests and lower elevations where they find abundant food. Grizzly bears, however, are typically found in more remote, higher-elevation areas, particularly in the northern Rockies. These bears differ in size, behavior, and habitat preferences, with grizzlies being larger and requiring larger territories. While black bear populations are generally stable, grizzlies are considered more vulnerable due to habitat loss and human interactions, making conservation efforts critical for maintaining healthy ecosystems where both species thrive.
