This data set represents statewide migration corridors or routes for bighorn sheep (Ovis canadensis) within the state of Wyoming. The original data was compiled by the Wyoming Game & Fish Department and produced on mylar map overlays which corresponded to U.S. Bureau of Land Management 1:100,000 scale quadrangle maps. Wyoming Open Spaces Initiative at the University of Wyoming digitized this hardcopy data to develop the original GIS layers in 2002. These have since been updated and continue to be maintained by the Wyoming Game and Fish Department.

Seasonal forages of desert bighorn sheep (Ovis canadensis nelsoni) were analyzed for dry matter, crude protein, in vitro digestibility, and cell wall content. Qualitative nutrient intake was estimated by combining chemical analyses with diet-composition data. Composite diets were also analyzed for the above parameters as well as for phosphorus and calcium. Dietary quality generally declined from spring to winter. Diet digestibility was good to excellent year-round, indicating that desert bighorn were receiving adequate energy. Protein levels were high in spring but were probably deficient for lactating ewes and young lambs in summer and fall. Diets were deficient in phosphorus in all seasons. Forbs had higher protein...
The single greatest obstacle to the restoration of large, healthy, populations of bighorn sheep (Ovis canadensis) in the western United States is epizootic outbreaks of bronchopneumonia that may kill 20–100% of the animals in populations. Although the species is capable of rapid initial growth rates following restoration into new habitat (λ = 1.23–1.30 have been observed), these rates of increase are typical only a few years following the release of a population, and then most populations either decline to extirpation or remnant status (<30 animals) or remain at <100 individuals. We studied the fecundity and survivorship of three increasing, and three declining and suspected diseased, populations of bighorn...

These data are an extraction of Bighorn sheep (Ovis canadensis) from the California Wildlife Habitat Relationship (CWHR) system dataset.The following information describes, and should always accompany, the California Department of Fish and Game's California Wildlife Habitat Relationship System (CWHR) species distribution data.The data is organized into four folders according to the four major taxonomic groups in CWHR: amphibians, reptiles, birds and mammals.  Each species is represented by a single shapefile and is named according to its 4 digit alpha-numeric CWHR ID code.  The file lookup.xls contains a record for each species including its CWHR ID, scientific name, common name, and  range map revision history.Each...
