In diverse regions around the country, impending crises over dwindling natural resources and conflicts over land use have given birth to a new approach to environmental management and policymaking. Known as bioregional assessment, the approach gives science and scientists a crucial role in the policymaking process, bringing together experts on a range of issues to assess existing ecological and social conditions and to provide a base of knowledge from which to develop policy options and management decisions.

A number of high-profile assessments have been conducted, and while much has been written on individual projects, little has been done to compare assessments or integrate the lessons they provide. Bioregional Assessments synthesizes the knowledge from many regions by examining the assessment process and detailing a series of case studies from around the country. Each case study, written by knowledgeable leaders from the region, features a detailed description of the project followed by reviews from the perspectives of science, management, and policy.

Case studies examined are the Forest Ecosystem Management Assess ment Team (FEMAT) Assessment; the Great Lakes-St. Lawrence River Basin Assessments; the Everglades-South Florida Assessments; the Northern Forest Lands Assessments; Southern California Natural Community Conservation Planning (NCCP); the Interior Columbia Basin Ecosystem Management Project; and the Sierra Nevada Ecosystem Project.

In addition, the book features introductory chapters that examine the challenges inherent in the assessment of complex regional systems, and the role of science in the assessment process. The concluding chapter provides a synthesis and analysis of the assessment process.

Bioregional assessments are quickly becoming an essential part of ecosystem management. This book provides a unique look at the theory and practice of bioregional assessments, and is an essential volume for resource managers, scientists, policymakers, and anyone involved with formulating or implementing strategies for regional planning and ecosystem management.

Tree sitters. Logger protests. Dying timber towns. An iconic species on the brink. The Timber Wars consumed the Pacific Northwest in the late 1980s and early1990s and led political leaders to ask scientists for a solution. The Northwest Forest Plan was the result.  

For most of the twentieth century, the central theme of federal forest management in the Pacific Northwest had been logging old-growth forests to provide a sustained yield of timber. During the 1970s and 1980s, however, a series of studies by young scientists highlighted the destructive impact of that logging on northern spotted owls, salmon, and the old-growth ecosystem itself.  

Combining this new science with newly minted environmental laws like the Endangered Species Act, environmental activists obtained court injunctions to stop old-growth logging on federal land, setting off a titanic struggle in the Pacific Northwest to find a way to accommodate conservation imperatives as well as the logging that provided employment for tens of thousands of people. That effort involved years of controversy and debate, federal courts, five science assessments, Congress, and eventually the president of the United States. It led to creation of the Northwest Forest Plan, which sharply and abruptly shifted the primary goal of federal forestry toward conserving the species and ecosystems of old-growth forests.   Scientists went from spectators to planners and guides, employing their latest scientific findings and expertise to create a forest plan for 20 million acres that would satisfy the courts. The largest upheaval in federal forest management in history had occurred, along with a precipitous decline in timber harvest, and there was no going back.  

In this book, three of the scientists who helped craft that change tell the story as they know it: the causes, development, adoption, and implementation of the Northwest Forest Plan. The book also incorporates personal reflections from the authors, short commentaries and histories from key figures— including spotted owl expert Eric Forsman—and experiences from managers who implemented the Plan as best they could. Legal expert Susan Jane M. Brown helped interpret court cases and Debora Johnson turned spatial data into maps. The final chapters cover the Plan’s ongoing significance and recommendations for conserving forest and aquatic ecosystems in an era of megafires and climate change.
