Haines Distinguished Lecture at the Fifth Biennial Scientific Conference on the Great Yellowstone Ecosystem, National Park Service, Yellowstone National Park, WY, October 11-13, 1999.Includes bibliographical references (page 276).Yellowstone's mission is clarified by analysis of the "natural" and the "unnatural." "Wild nature" denotes, outside culture, evolutionary and ecological natural history present on the landscape, jeopardized by numerous human influences, including exotic species. Natural processes can be preserved because of, rather than in spite of, park management. Yellowstone provides an opportunity to encounter and to conserve nature as an end in itself, past, present, and future.born digitalarticleseng©2001 Brigham Young University.Copyright and other restrictions may apply.
