Tbc winter distribution of prongborn over a 142-km2 area on the Desert Experimental Range was significantly related to sheep grazing during the current winter, presence of black sagebrush, and topographic characteristics. Even moderate sheep use during the dormant period left grazing units relatively unfavorable for pronghom until spring regrowth-at least on ranges where key pronghom forage plants were in short supply. Winter use areas preferred by pronghom were above the valley bottoms in
