Book Description
Rocky Mountain bighorn sheep (Ovis canadensis canadensis) were reported to occur in all mountain ranges in and around Yellowstone National Park (YNP) in the late 1800's (Mills 1937). European expansion into the upper Yellowstone River Valley during the 19th century caused bighorn sheep numbers to drastically decline from competition with livestock, introduction of livestock disease, hunting, and loss of habitat. The establishment of YNP, other management areas, and hunting regulations protected remaining bighorn populations. Although some populations were eliminated, others increased and reestablished into historic ranges (Buechner 1960, Keating 1982).

CHAPTER 2: Habitat-use models for wildlife reintroductions are important management tools. Such predictive models can save managers time and money by ensuring animals are released into suitable habitats. We tested predictive winter and lambing habitat-use models constructed by Whiting et al. (2004) for Rocky Mountain bighorn sheep (Ovis canadensis canadensis) on Mount Nebo, Utah. We used ArcGIS 9.2 to determine the number of bighorn sightings observed in predicted habitats. Additionally, we documented which variables were violated for bighorn sightings outside of modeled habitats. Our results showed that bighorns used predicted slopes, elevations, and vegetation cover types only 40% to 60% of the time during both seasons. Furthermore, only 14% of winter sightings (n=70) and 18% of lambing sightings (n=55) occurred within habitats predicted by Whiting et al. (2004). Finally, we offer suggestions to improve both models, which will aid in the restoration and conservation of bighorns in Utah.

Book Description
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.
