Technical Abstract: Livestock grazing has been indirectly related to sage grouse declines in the western United States and southern Canada; however, there is a lack of scientific research that directly relates the two. An 18-day trial was conducted to determine the level of utilization at which cattle begin to access herbaceous vegetation under the canopy of sagebrush plants; these herbaceous plants can provide important screening cover for nesting sage grouse. Our results suggest that cattle use of understory plants was minimal until pasture utilization exceeded about 35% utilization (by weight). These results can be used to help land managers develop grazing plans which minimize the impacts of grazing livestock on herbaceous cover important to nesting sage-grouse.
