Local rural residents have the opportunity to harvest for a subsistence way of life on federal public lands. In 1980, the Alaska National Interest Lands Conservation Act (ANILCA) added a purpose to Arctic Refuge to "provide the opportunity for continued subsistence uses by local residents." Subsistence includes the harvest of plants, fish, and wildlife for food, clothing, and/or shelter. Laws such as ANILCA protect traditional and customary subsistence activities and define who can legally participate. For more information about subsistence visit http://www.doi.gov/subsistence.
