DOWNLOAD EBOOKThe 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.

The Alaska Fisheries Science Center is the research branch for marine life and coastal oceans off parts of the U.S. west coast and Alaska. This includes the Eastern Bering Sea where some the worlds most important commercial fishing takes place. Their mission is to develop and maintain scientific exploration to help understand and manage that region's environment. Over the years there have been many reports published which discuss their findings; this is one of them.
