The Seventh World Wilderness Congress met in Port Elizabeth, South Africa, in 2001. The symposium on science and stewardship to protect and sustain wilderness values was one of several symposia held in conjunction with the Congress. The papers contained in this proceedings were presented at this symposium and cover seven topics: state-of-knowledge on protected areas issues in South Africa; traditional and ecological values of nature; wilderness systems and approaches to protection; protection of coastal/marine and river/lake wilderness; spiritual benefits, religious beliefs, and new stories; personal and societal values of wilderness; and the role of science, education, and collaborative planning in wilderness protection and restoration.
