Book Description
This report is the fourth in a series of ongoing investigations of large sockeye salmon escapements in the Kenai River system and in Rad and Akalura lakes on Kodiak Island. The overescapement event resulted from over abundance of juvenile salmon rearing in lakes caused by presence of Exxon Valdez oil on the fishing grounds in Cook Inlet and the Kodiak area in 1989.

Book Description
Shifting Baselines explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems. Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public. While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.

Book Description
In North America, concepts of Historical Range of Variability are being employed in land-management planning for properties of private organizations and multiple government agencies. The National Park Service, U.S. Fish & Wildlife Service, Bureau of Land Management, U.S. Forest Service, and The Nature Conservancy all include elements of historical ecology in their planning processes. Similar approaches are part of land management and conservation in Europe and Australia. Each of these user groups must struggle with the added complication of rapid climate change, rapid land-use change, and technical issues in order to employ historical ecology effectively. Historical Environmental Variation in Conservation and Natural Resource Management explores the utility of historical ecology in a management and conservation context and the development of concepts related to understanding future ranges of variability. It provides guidance and insights to all those entrusted with managing and conserving natural resources: land-use planners, ecologists, fire scientists, natural resource policy makers, conservation biologists, refuge and preserve managers, and field practitioners. The book will be particularly timely as science-based management is once again emphasized in United States federal land management and as an understanding of the potential effects of climate change becomes more widespread among resource managers.
