Interactions between Mule Deer and Cattle on Big Sagebrush Range in British Columbia

Abstract

Interaction between deer and cattle took various forms. The potential for direct competition was greatest in spring. Both deer and cattle selected bluebunch wheatgrass and crested wheatgrass while Sandbergs bluegrass was most often used by deer. Evidence of indirect interaction was observed. Moderate or heavy fall grazing by cattle made the spring forage more attractive to deer by removing mature forage. Light grazing did not exert any appreciable effect on deer distribution.
