AbstractControl of low sagebrush in northern Nevada increased productivity of understory grass species. On fair condition sites, climax dominant species such as Idaho fescue, bluebunch wheatgrass, and Thurber needlegrass gave a yield response but the response was not obtained for 2 years after treatment. However, the rapid response of Sandberg bluegrass resulted in a significant total perennial grass response the year after treatment. On poor condition sites, squirreltail gave a smaller response and the response was not obtained for 2 to 4 years after treatment. Dense stands of annual species gave a large yield response the year after treatment and suppressed the response of squirreltail. Scattered stands of annuals did not respond until 4 years after treatment. Soil moisture relations explained differences in total yield. However, differences in early spring growth were attributed to soil nitrogen.
