Responses of Desert Bighorn Sheep to the Removal of Anthropogenic Water Sources
Wildlife managers have assumed for years that the availability of free-standing water was a primary factor limiting the distribution, productivity, and recruitment of desert ungulates in the southwestern United States. As a result, wildlife management agencies and sportsman's organizations hav...
