The Endangered Species Act of 1973 (ESA) is one of the most cherished and reviled laws ever passed. It mandates protection and preservation of all the nation’s species and biodiversity, whatever the cost. It has been a lightning rod for controversy and conflicts between industry/business and environmentalists. The year 2023 marks the 50th anniversary of this law, and provides an opportunity for a measured and thorough evaluation thereof. We cannot know today’s challenges and opportunities without understanding their histories. This book is the most comprehensive history of the ESA ever published, and the first to consider the entire history of the law from all angles in a single volume. The history of the ESA has been one of increasing impact, complexity, and controversy. In 1978, the Supreme Court declared that Congress intended for the U.S. government to save all species at any cost, and thereafter application of the ESA became steadily more controversial, as seen in the example of the northern spotted owl and the timber wars in the Pacific Northwest in the late 1980s and early 90s, and then everywhere as the ESA became a political football in the highly partisan environment of the late 1990s and amendments to the law ceased. This book is not only a history, but a call to action. It will take more conservation, more funding, and more innovative solutions if we are to save our wildlife and biodiversity. It will take the engagement to every American to muster the collective will to meet this challenge. The hope of this book is that we will be able to look back and say that we accomplished more in the second 50 years of the ESA than we did in the first.

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.
