3.3.3 Test. Plot 2: 24" <br />Cover <br />' The total vegetation cover for this treatment plot was 47.240. Graminoids accounted <br />for 28.0% mean cover, while forbs and woody plants were represented by 5.2% and <br />' 14.0% mean cover each. Litter provided 24.8% total cover, rock 0.4%, and bare <br />ground 27.6%. Cover results for this treatment are found in Table 15. <br />Grass species were dominated by Bromus japonicus/tectorum with 23.6°!o mean cover <br />(49.296 relative cover). Additional grass species included Agropyron cristatum at 2.8% <br />mean cover (5.3% relative cover) and Elymus junceus (Russian Wildrye) with 1.69b <br />' mean cover and 3.0% relative cover. <br />Forts were represented by Descurainia sophia comprising 4.846 mean cover (9. I %O <br />1 relative cover) and Chorispora tene/la with 0.4% mean and 0.8% relative cover. <br />Both are annual introduced species characteristic of disturbed and/or open areas. <br />Woody plants were represented in cover sampling by three species. Atriplex <br />confertifolia accounted for 10.4% mean and 23.9% relative cover. Sarcobatus <br />' rrrmiculatus represented 2.0% mean cover (4.6% relative cover), while Atriplex <br />canescens accounted for 1.6% mean cover and 4.2% relative cover. <br />Herbaceous Production <br />Total herbaceous production on this treatment plot was 115.46 g/m2 (1O27.61b/acre). <br />Agropyron cristatum was the dominant species, accounting for 63.38 g/mz and 54.9% <br />of the total herbaceous production. Bromus japonicus/tectorum produced 36.42 glm2 <br />for 31.5% of total production. Agropyron smithii and Elymus junceus were minor <br />contributors to perennial grass production at 5.98 g/mz . Two annual forbs accounted <br />for 8.4% of total production. Table 16 presents the results of herbaceous production <br />sampling for this treatment. <br />' Woody Plant Density and Dimensions <br />' There were 113 woody plants counted on this plot for a density of 1070/acre. Four <br />species were present with Atrip/ex confertifiiia dominating, followed by Atriplex <br />' canescens, Chrysotharnnus nauseosus, Sarcobatus vermicu/atus, and Artemesia <br />tridentate. In this plot the largest woody plant was an Atriplex canescens individual <br />measuring 153 cm high by 167 cm in diameter, making it the sewnd largest woody <br />' plant in the test plots. Woody Plant information for all plots is presented in Tables 29 <br />and 30. <br />37 <br />
