Wild Forests: Conservation Biology And Public PolicyIsland Press, 05.03.2013 - 323 Seiten Wild Forests presents a coherent review of the scientific and policy issues surrounding biological diversity in the context of contemporary public forest management. The authors examine past and current practices of forest management and provide a comprehensive overview of known and suspected threats to diversity. In addition to discussing general ecological principles, the authors evaluate specific approaches to forest management that have been proposed to ameliorate diversity losses. They present one such policy -- the Dominant Use Zoning Model incorporating an integrated network of "Diversity Maintenance Areas" -- and describe their attempts to persuade the U.S. Forest Service to adopt such a policy in Wisconsin. Drawing on experience in the field, in negotiations, and in court, the authors analyze the ways in which federal agencies are coping with the mandates of conservation biology and suggest reforms that could better address these important issues. Throughout, they argue that wild or unengineered conditions are those that are most likely to foster a return to the species richness that we once enjoyed. |
