註釋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 extinction--and what this understanding means to implementation of the ESA. Habitat--its destruction, conservation, and fundamental importance to the ESA--is explored in detail.
The book analyzes
  • Concepts of species--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 ESA--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.
