Ecological investigation of Dall sheep (Ovis dalli dalli, Nelson) and their habitat on Sheep Mountain, Kluane National Park, Yukon Territory, Canada

A stable population of approximately 200 Dall sheep (Ovis dalli dalli) on Sheep Mountain, Kluane National Park, Yukon Territory, Canada, was observed from 1969 to 1973. The study revealed detailed population dynamics, including natality and mortality rates, sex ratios, and productivity, while also analyzing the sheep's range use patterns and forage selection across different biogeoclimatic zones. Environmental variables such as temperature, wind, and snow depth were found to influence sheep behavior. A population structure model was developed, providing valuable insights for sustainable management practices, including calculating allowable harvests. The research combined geographical, geological, glaciological, and phytosociological data with detailed demographic analysis.
