Hutto is living in a tent at twelve thousand feet, where blizzards occur in July and where human wants become irrelevant and human needs can become a matter of life and death—to study the Rocky Mountain bighorn sheep. The population of these rare alpine sheep is in decline. The lambs are dying in unprecedented numbers. Hutto’s job is to find out why. For months at a time, he follows the bighorn herds, meets mountain lions and bears, weathers injury and storms, and beautifully observes the incredible splendor of the Rocky Mountains. Hutto has a deep connection to Wyoming, having managed a large cattle ranch in his past. He weaves Wyoming’s history of the cowboy, mountain ecology, and the lives of the bighorn sheep into a beautiful flowing narrative. Ultimately, he discovers that the lambs are dying of cystic fibrosis due to selenium deficiency, which is caused by acid rain—a grim ecological disaster caused by human pollution. Here is a new twist on a cautionary tale, and a new voice, eloquently expressing the urgency that we mend our ways.

Mountain sheep epitomize wilderness for many people because they occupy some of the most inaccessible and rugged habitats known to man, from desert crags to alpine mountains. But of all hoofed mammals in North America, wild sheep present the greatest management problems to biologists. This book is a major reference on the natural history, ecology, and management of wild sheep in North America. Written by wildlife biologists who have devoted years of study to the animals, it covers Dall's and Stone's sheep and Rocky Mountain, California, and desert bighorn and examines a variety of factors pertinent to their life histories: habitat, diet, activity, social organization, reproduction, and population dynamics. Additional chapters consider distribution and abundance, adaptive strategies, and management guidelines. Discussions on diseases of wild sheep present a wealth of information that will be of particular use to wildlife biologists, including detailed clinical descriptions of conditions that threaten sheep populations, from pasteurellosis to capture myopathy. An appendix reviews the cytogenetics and genetics of wild sheep. North American wild sheep may face extinction in many areas unless critical questions concerning their management are answered soon. Prior to the publication of this book, there was no single reference available in which one could find such a synthesis of information. Mountain Sheep of North America provides that source and points toward the preservation of these magnificent wild creatures.

The foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance. While there was great understanding of how to manage wildlife in Europe, where wildlife management was an old, mature profession, Continental methods depended on social values often unacceptable to North Americans. Even Canada, a loyal colony of England, abandoned wildlife management as practiced in the mother country and joined forces with like-minded Americans to develop a revolutionary system of wildlife conservation. In time, and surviving the close scrutiny and hard ongoing debate of open, democratic societies, this series of conservation practices became known as the North American Model of Wildlife Conservation. In this book, editors Shane P. Mahoney and Valerius Geist, both leading authorities on the North American Model, bring together their expert colleagues to provide a comprehensive overview of the origins, achievements, and shortcomings of this highly successful conservation approach. This volume • reviews the emergence of conservation in late nineteenth–early twentieth century North America • provides detailed explorations of the Model's institutions, principles, laws, and policies • places the Model within ecological, cultural, and socioeconomic contexts • describes the many economic, social, and cultural benefits of wildlife restoration and management • addresses the Model's challenges and limitations while pointing to emerging opportunities for increasing inclusivity and optimizing implementation Studying the North American experience offers insight into how institutionalizing policies and laws while incentivizing citizen engagement can result in a resilient framework for conservation. Written for wildlife professionals, researchers, and students, this book explores the factors that helped fashion an enduring conservation system, one that has not only rescued, recovered, and sustainably utilized wildlife for over a century, but that has also advanced a significant economic driver and a greater scientific understanding of wildlife ecology.
