Science And The Endangered Species Act

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.

The complex regulations of the Endangered Species Act can be challenging for environmental professionals who must comply with them or assist clients in compliance. This volume discusses the Act using clear scientific prose that all professionals can readily comprehend. It explores the history and the basic scientific theory underlying the Act. It provides an overview of its key provisions and examines the Act in the context of other key environmental planning statutes. The book also details the regulatory processes faced by other government agencies and private developers who must routinely ensure that their actions are in compliance.

This handbook is a guide to the federal Endangered Species Act, the primary U.S. law aimed at protecting species of animals and plants from human threats to their survival. It is intended for lawyers, government agency employees, students, community activists, businesspeople, and any citizen who wants to understand the Act--its history, provisions, accomplishments, and failures.

In The Science of Conservation Planning, three of the nation's leading conservation biologists explore the role of the scientist in the planning process and present a framework and guidelines for applying science to regional habitat-based conservation planning. Chapters consider history and background of conservation planning efforts, criticisms of science in conservation planning, principles of conservation biology that apply to conservation planning, detailed examination of conservation plans, and specific recommendations for all parties involved. The Science of Conservation Planning will serve as a model for the application of conservation biology to real-life problems, and can lead to the development of scientifically and politically sound plans that are likely to achieve their conservation goals, even in cases where biological and ecological information is limited.

The new model of policy design theory frames the discussion regarding the frequently analyzed Endangered Species Act (ESA) in this historical perspective. Since the 1970s, the Endangered Species Act (ESA), by virtue of its regulatory impact, has been a frequent subject of policy analysis. In this comprehensive history and critique of the ESA, Brian Czech and Paul R. Krausman incorporate the new model of policy design theory to frame a larger discussion about conservation biology and American democracy. Czech and Krausman provide a historical background of endangered species policy that integrates natural history, socioeconomic trends, political movements, and professional developments. Outlining the controversies surrounding the ESA, they find a connection between challenges to species conservation and challenges to democracy. After an assessment of ESA analyses that have been performed from traditional perspectives, they engage policy design theory to review the structural logic of the ESA, analyzing each clause of the legislation for its application of the fundamental elements of democracy. To address the technical legitimacy of ESA, they propose two new genetic considerations—functional genome size and molecular clock speed—to supplement phylogenetic distinctiveness as criteria with which to prioritize species for conservation. Next, they systematically describe the socioeconomic context of ESA by assessing and classifying the causes of species endangerment. A hybrid of policy analysis and ecological assessment, The Endangered Species Act: History, Conservation Biology, and Public Policy will appeal to scholars and students in the fields of natural resource policy and law, conservation biology, political science, wildlife ecology, and environmental history, and to professionals at agencies involved in wildlife conservation.
