Few Endangered Species Act (ESA) species reintroductions have been as controversial as that of the gray wolf. Sweeping in scope, rich in details, this volume offers the first comprehensive chronological review of gray wolf reintroduction and recovery in the northern Rocky Mountains. This incisive analysis of the efficacy and impact of public law litigation provides a superb tool for anyone—students, professors, wildlife managers, individuals—working within the public law sector. An eminent environmental law expert, Fitzgerald begins by examining the role of the US courts in resolving public policy issues and the powerful nexus of science, policy, and politics that took the gray wolf from extirpation to recovery. Ensuing chapters offer accounts of each successive presidential administration’s interpretation of public law for this species and elucidate how western states' opposition to federal wolf policy enabled politics to prevail over science. Fitzgerald's penetrating insights on agency and court responses to challenging concepts such as taxonomical issues, the distinct population segment concept, and the congressional delisting of this species via an appropriations rider illustrate that this compelling book goes beyond wolves—it is about the battle over the ESA. Summing Up: Essential. All readers.
