Abstract

Data have been collected from 05-86 to 11-87 to aid in the development of a management program for Rocky Mountain bighorn sheep (Ovis canadensis canadensis) at Bighorn Canyon National Recreation Area (BICA). The purpose of this report is to summarize progress toward completing the following Objectives: 1. Determine the size, and age/sex composition of the sheep herd at BICA; determine the general health of the herd. 2. Analyze the seasonal food habits of sheep and wild horses; analyze the dietary overlap of these species; analyze the foraging behavior of sheep in habitats occupied exclusively by sheep and compare with the foraging behavior of sheep in habitats used in common with horses and/or humans. 3. Analyze seasonal habitat use throughout the annual cycle; analyze activity patterns during all daylight hours and relate to habitat use; identify and describe sensitive use areas for consideration in future sheep management programs. 4. Determine the total habitat potential of BICA.
