1 <br />Grass species were dominated by Bromus japonicus/tectorum at 14.4 % mean cover <br />' (54.6°6 relative cover). Subdominant species included ,ggropyron cristatum at 3.646 <br />mean cover (13.6% relative cover), and Agropyron smithii, and Agropyron <br />' trachycaulum (Slender Wheatgrass), each accounting for 2.8% mean cover and 11.4% <br />relative cover. <br />' Forb species included the annuals Lepidium montanum (Pepperweed) at 1.2% mean <br />cover (4.6% relative cover) and Dlescuramia Sophia (Flixweed) at 0.4% mean cover <br />(1.5% relative cover). These forb species represent annual introduced species <br />' characteristic of disturbed areas. <br />The single woody plant represented in cover sampling was Atriplex canescens (Four <br />' Wing Saltbush) at 0.4% mean cover and 1.5% relative cover. Four Wing Saltbush is a <br />long-lived native shrub characteristic of dry areas in the west. <br />' Herbaceous Production <br />' Total herbaceous production on this treatment plot was 63.4 g/mz (564.26 Ib/ac). The <br />perennial grass Agropyron cristatum dominated herbaceous production with 21.78 g/mz <br />or 34.346 of total production. Bromus japonicus/tectorum was next in dominance with <br />' 19.92 g/m2 or 31.4% of total production. The perennial grasses Agropyron smithii, <br />~ropyron trachycaulum, and a Festuca species accounted for the remaining perennial <br />grass production of 19.38 g/m2 (30.6 %) of the total production. Five annual forts <br />' produced 2.3g/mz for 3.6% of the herbaceous production. Table 6 lists herbaceous <br />production results for this treatment. <br />t Woody Plant Density and Drmeasious <br />Fifteen woody plants were counted on this plot for a density of 218/acre. Five species <br />' were present. Predominant was Atriplex confertifolia, followed by Chrysothamnus <br />nauseosus, Atriplex canescens, Sarcobatus r~ermiculatus, and Artemesia tridentate. The <br />largest woody plant was a Chrysothamnus nauseosus individual measuring 92 cm high <br />' by 127 cm in diameter. <br />' Species Diversity <br />On this treatment, five lifeforms were represented. They included four perennial <br />' grasses, one annual grass, two annual forts, one woody plant, and one cryptogam. Of <br />these, only three perennial grasses, one annual grass, and one annual forb represented <br />species with greater than three percent relative cover. <br />' 31 <br />
