Dall's sheep are alpine adapted and mostly non-migratory. They are sensitive to environmental changes including harsh weather events, long-term environmental change, nutrition, predation and hunting, parasites, and disease. They are also an important subsistence resource, especially when caribou are scarce, as well as highly valued by sport hunters and wildlife enthusiasts. The National Park Service monitors Dall's sheep populations to understand the condition of the species and protect them in parks.
