Mammals of Crater Lake National Park

The abundant and diverse vegetation of the park constitutes a large block of relatively undisturbed habitat that supports various populations of native wildlife species. The park has significant populations of Roosevelt elk, black tail deer, pronghorn, coyote, and porcupine. Periodic sightings of black bear, pine marten, weasel, and mountain lion are reported in the summer months. A variety of other small animal species are seen in the backcountry of the Park.
