This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1982 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: A herd of California bighorn sheep (Ovis canadensis californiana), re-introduced to the area of Hell Creek on the Sheldon National Wildlife Refuge in northwestern Nevada, was studied from 15 June 1978 to 20 August 1980. Major vegetation and physiographic types were delineated and described. Habitat preferences were determined from field observations of sheep use of both vegetation and physiographic habitat components. Sheep displayed preference in their use of habitat components during all seasons; greatest selection was shown by the ewe/ lamb band for physiographic types associated with escape cover in spring, and for vegetation types associated with quality forage in winter. Rams generally displayed less selective habitat use than did the ewe/lamb band. The population was relatively stable at 30-35 individuals, following the initial post-introduction period of rapid growth. It was hypothesized that high quality lambing terrain was limited in quantity within the present ewe/lamb range, and that expansion of the ewe/lamb range to include the nearby Boulder Spring and Virgin Canyon areas would promote substantial population increase. Water was available during all seasons. Spring use of mineral licks may have been related to seasonal mineral deficiency associated with tissue and/or milk production. Activity patterns suggested that sheep adapted their daily activities to fit local, seasonal situations.

This book was released on 2004 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-elevation habitats may pose problems for reintroduced bighorn sheep where fire suppression and human presence have altered the landscape. Because male and female bighorn segregate for much of the year, habitat use may differ and impose new management strategies for restoring and maintaining populations of bighorn in these unique habitats. Seasonal, sex-specific habitat use was studied in a northwest Nebraska population of bighorn sheep from January- August, 2002 and 2003. Close proximity to escape terrain was a significant component of habitat selection models for all group types in all seasons, except winter 2002 for mixed-sex groups. Elevation was also important in habitat selection by all group types in all seasons, except males in spring 2003, with bighorn sheep found at lower elevations than random points. Slope was an important component during most seasons with all groups selecting areas with steeper slopes. Although not important in habitat selection by males, aspect was an important component of habitat selection by females and mixed-sex groups in 2003. Habitat type was important to males and females in spring and summer, but not for mixed-sex groups. Mixed-sex groups and female groups in winter and spring were found farther from water than expected. Distance to disturbance, although not important to mixed-sex groups, only appeared important to females in summer, when they were found closer to disturbance, and males in spring 2002, when they were found farther than expected from disturbance features. Sex differences in habitat use included female bighorn using areas closer to escape terrain and disturbance features, and lower in elevation than male bighorn. Although segregation of male and female bighorn sheep occurred during the spring and summer seasons, use of habitat types did not differ. Visibilities did not differ between male and female locations. When segregated, habitat use by male and female bighorn in the Pine Ridge appears to be regulated primarily by escape terrain with habitat type, slope, and elevation also being important factors. Continued survival and expansion of bighorn sheep in the Pine Ridge should focus on protection of current areas of use from disturbance and identification and enhancement of similar habitats.
