The Tongass National Forest is the largest National Forest in the nation, encompassing some 17 million acres of land in Southeast Alaska. Numerous towns and villages lie in and adjacent to the forest, and many Alaska Native and other residents regularly undertake fishing, hunting, and other subsistence activities within its boundaries. As required by NEPA, timber development potentially occurring on National Forest lands must be preceded by an environmental impact assessment process and, in some cases, steps must be taken to mitigate any potentially deleterious development-related impacts on persons and groups who use the lands for recreation, subsistence, or certain other uses. This study contributed to the EIS process and assessment of subsistence uses in advance of prospective timber development on remote Prince of Wales Island in southernmost Alaska.
