The elk, or wapiti (Cervus canadensis), is the second largest species of deer in the world, and one of the largest mammals in North America and eastern Asia. Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves and bark.
The largest of the subspecies is the Roosevelt elk, found west of the Cascade Range in the U.S. states of California, Oregon and Washington, and in the Canadian province of British Columbia. Throughout their range, they live in forest and in forest edge habitat, similar to other deer species. In mountainous regions, they often dwell at higher elevations in summer, migrating down slope for winter.
