Desert Bighorn Sheep in the Dominguez-Escalante National Conservation Area, Colorado.

Responses by large herbivores to human disturbance can result in a change in their habitat use, movements, and increased vigilance and decreased foraging time. Increased movements and reduced foraging time result in higher energetic costs and lower energetic gains, potentially decreasing fitness. The goal of this project is to determine potential impacts of increasing recreational activities on desert bighorn sheep in the Dominguez-Escalante National Conservation Area, Colorado and develop management recommendations as appropriate to mitigate negative effects of recreation on desert bighorn sheep herds.
