Cover Requirements

The pronghorn is the fastest North American mammal, reaching speeds of up to 70 km an hour (50mph) (Davis and Schmidly 1994). A pronghorn uses this speed to put distance between itself and its predators. Pronghorn therefore require open cover, either grassland or grassland interspersed with low shrubs that provides long-range visibility (Hailey and DeArment 1972). The mean height of vegetation cover where pronghorn typically occupy is 15 inches (Boyd, Cooperrider, Lent, and Bailey 1986). During fawning, does will seek areas with greater than average shrub cover and height (Autenrieth 1976). Fawns under 3 weeks old tend to stay in their birthing area (Alldredge, Deblinger, and Peterson 1991), using the tallest vegetation in the area for cover (Autenrieth 1978).
