In 1968 the residents of Lovell, Wyoming, began the work of saving the Pryor Mountain Mustang, a breed of horse with a genetic link dating back to the sixteenth-century Spanish conquistadores’ horses. In this moving case study, Christine Reed shows how, through a grassroots campaign, these residents championed the creation of the first federal public wild horse range. Crucial to this provocative analysis of local-federal cooperation is the relationship that grew between the Lovell advocates, the Bureau of Land Management, and the National Park Service. Long before there were federal laws passed to protect wild horse herds across the western states, the Pryor Mountain Mustang was preserved through the cooperative efforts of local residents and federal officials. Saving the Pryor Mountain Mustang explores the unique and ongoing relationship between locals and the federal government, highlighting the Lovell citizens’ philosophy of cooperation instead of the typical mistrust that exists between wild horse advocates and federal agencies. The book provides a rich analysis of how a determined group of people saved an endangered wild horse herd. The book will have wide appeal to wild horse activists, scholars of local and federal governance, and western history enthusiasts.
