ubiquitous invader of sagebrush rangelands, cheatgrass (Bromus tectorum) had the highest <br />cover for any species at 12.7 percent (90 percent frequency). Kentucky bluegrass had the third <br />highest cover at 2.7 percent (43 percent frequency) and blue grama (Bouteloua gracilis), <br />crested wheatgrass (Agropyron desertorum), hairy goldenaster (Heterotheca villosa), broom <br />snakeweed (Gutierrezia sarothrae) all had approximately 1 percent cover. The remaining <br />species generally contributed less than one half percent cover to the mean total vegetative <br />cover. <br />Herbaceous production totaled 20.0 g/m2 or 178.4 pounds/acre (Table 2.04.10-12). The <br />perennial grass component contributed the highest value at 13.6 g/m (242.4 pounds/acre) <br />followed by perennial forbs at 5.4 g/m2 (96.2 pounds/acre). While the contribution of annual <br />grasses 2 and forbs was low (0.2 and 0.8 g/m2, respectively), their actual contribution to annual <br />production is most likely higher. In order to sample the perennial species at the peak of their <br />production, many of the earlier maturing annual species were senescent or were already gone <br />from the stand. <br />February 2015 (TR -66) 2.04.10-43 <br />
