A Pass for Antelope in Sheep-Tight Fences

Abstract

A Wyoming study has resulted in development of an inexpensive, easily installed pass structure that facilitates movement of pronghorn antelope through fences and retains livestock. Patterned after the common cattleguard, the antelope pass consists of a 5 1/2 × 6-foot lightweight grill installed on timbers over a 15-inch pit with earth ramps on each end. Proper location and installation are essential to obtain use by antelope. Adjustment and learning through experience and association are important factors in the effectiveness of pass structures. Total cost including installation, is less than $100 per unit.
