Summer Habitat Use by Mountain Sheep

Abstract
Summer habitat use by mountain sheep (Ovis canadensis mexicana) was examined in the Pusch Ridge Wilderness (PRW), Santa Catalina Mountains, Arizona, during 1982 and 1983. Diurnal sheep activity was concentrated in areas ≤50 m of escape terrain. Sheep selected nonprecipitous open oak (Quercus spp.) woodland associations. Slopes of 59-79% and elevations of 1,098-1,341 m were selected on upper slopes of drainages or on the tops of ridges or mountains. Ewe-juvenile groups selected more precipitous areas than ram groups and mixed groups. Groups with lambs used steeper and lower areas than groups without lambs.
