Evaluating areas of high conservation value in Western Oregon with a decision-support model.

摘要: The Northwest Forest Plan was implemented in 1994 to protect habitat for species associated with old-growth forests, including Northern Spotted Owls (Strix occidentailis caurina) Washington, Oregon, and northern California (U.S.A.). Nevertheless, 10-year monitoring data indicate mixed success meeting the ecological goals of plan. We used ecosystem management decision-support model evaluate terrestrial aquatic habitats across landscape on basis objectives Plan, which included maintenance late-successional forest, recovery, Pacific salmon (Oncorhynchus spp.), viability Owls. Areas that contained characteristics supported these were considered high conservation value. condition each 36, 180 township range sections study area.
