This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
Summarizes the science of climate change and impacts on the United States, for the public and policymakers.
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
This report provides a detailed snapshot of our nation's passion for wildlife and nature. It serves as a road map to guide efforts to reach more Americans to provide them with opportunities to hunt, fish, and enjoy America's wildlife and wild places. Bird/wildlife watching, hunting, fishing are not just favorite pastimes, but they share revenues from sale of licenses and tags, as well as excise taxes paid by hunters, anglers, and shooters to continue to support vital wildlife and habitat conservation efforts in every state. The report outlines the details for compilation of information and surveys to different populations and provides highlights along with statistical information represented in tables from the data collected.

"Biodiversity." As argument over environmental and conservation policy grows more heated in California and throughout the nation, the term has become a buzzword. But what does biodiversity really mean? What really threatens it? Why should we care? In Our Own Hands offers a readable, scientifically sound view of California's biological diversity and what must be done to preserve it. The book will be an invaluable resource for environmental and natural resource specialists, educators, and general readers. Local and global forces threaten California's wetlands, dunes, oak woodlands, and riparian forest habitats--all declining habitats in a rapidly urbanizing, culturally heterogeneous, and politically turbulent state. Always a bellwether, California will be a model for the rest of the United States in its scientific and political solutions to conservation problems. This book proposes the first steps toward a unified national conservation policy for the twenty-first century. "Biodiversity."

The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits. In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective. The committee provides an overview of what scientists know about extinctionâ€"and what this understanding means to implementation of the ESA. Habitatâ€"its destruction, conservation, and fundamental importance to the ESAâ€"is explored in detail. The book analyzes: Concepts of speciesâ€"how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESAâ€"how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts. It will be useful to policymakers, regulators, scientists, natural-resource managers, industry and environmental organizations, and those interested in biological conservation.
