Uncertainty can take many forms, can be represented in many ways, and can have important implications in decision-making and policy development. This book provides a rigorous scientific framework for dealing with uncertainty in real-world situations, and provides a comprehensive study of concepts, measurements, and applications of uncertainty in ecological modeling and natural resource management. The focus of this book is on the kinds and implications of uncertainty in environmental modeling and management, with practical guidelines and examples for successful modeling and risk analysis in the face of uncertain conditions and incomplete information. Provided is a clear classification of unc...
These proceedings include 41 papers focusing attention on the need to integrate management of snags - dead or deteriorating trees critical to needs of cavity-dependent wildlife - with other resource uses and demands. Sessions concentrated on management, habitat and species requirements, and monitoring and modeling.
The Bruce G. Marcot Spotted Owl Collection consists of materials assembled or generated by research wildlife biologist Bruce G. Marcot pertaining to the spotted owl, management of its habitat, and its status as an endangered species. The Collection includes publications, reports, and studies created by various agencies and organizations including the U.S. Forest Service, OSU Fisheries and Wildlife Department, U.S. Department of the Interior, the Louisiana-Pacific Corporation, the National Council for Air and Stream Improvement, and the Interagency Spotted Owl Scientific Committee. The Collection also includes correspondence between Marcot and others involved in the spotted owl research and management as well as student theses. While the bulk of the collection pertains to the Pacific Northwest (Oregon, Washington, northwestern California, and British Columbia), it also includes materials pertaining to the spotted owl in the Sierra Nevada of California and the southwestern United States.
Some ecosystem management plans established by state and federal agencies have begun to shift their focus away from single-species conservation to a broader goal of protecting a wide range of flora and fauna, including species whose numbers are scarce or about which there is little scientific understanding. To date, these efforts have proved extremely costly and complex to implement. Are there alternative approaches to protecting rare or little-known species that can be more effective and less burdensome than current efforts? Conservation of Rare or Little-Known Species represents the first comprehensive scientific evaluation of approaches and management options for protecting rare or little...
