1 <br />Species Diversity <br />This treatment plot had the fewest species of all areas sampled. Four lifeforms were <br />represented on this treatment plot. They included one perennial grass, one annual <br />grass, two annual forbs, and one woody plant. Of these, one annual grass, one annual <br />fort, and one woody plant represented species with greater than three percent relative <br />cover. <br />' 3.4.2 Test Plot 3: 12" <br />Cover <br />Total vegetation cover for this treatment was 54.0%. Graminoids accounted for 49.6% <br />mean cover, forbs 2.830 mean cover, and woody plants 1.2% mean cover. Litter <br />' accounted for 20.0% total cover, rock 1.2%, and bare ground 24.8%. Table 19 <br />represents the results of cover sampling in this treatment. <br />Bromus japonicus/tectorum at 44.4% mean cover (81.5% relative cover) was the <br />predominant grass. Subdominant grasses included Elymus junceus at 2.430 mean cover <br />' (4.330 relative cover) and .~gropyron cristatum with 2.0% mean cover (3.6% relative <br />cover). Agropyron smithii accounted for 0.8% mean cover and 1.4% relative cover. <br />' Chorispora tenella was the dominant fort with 2.436 mean and 5.0% relative cover. <br />Ceratocephala orthoceras and Cardaria pubescens (Whitetop) each accounted for 0.4% <br />mean cover and 1.136 relative cover. <br />' The single woody plant represented in cover sampling was Amp/ex confertilvlia at <br />1.2% mean cover and 2.1% relative cover. <br />' Herbaceous Production <br />Total herbaceous production for this treatment was 193.08 g/m2 (1718.41 16/ac). <br />Bromus japonicus/fectorum dominated the herbaceous production with 123.76 g/mz or <br />64.1% of total production. Agropyron cristatum accounted for 31.8 g/m2 and 16.5% <br />of total production, and all perennial grasses accounted for 18.6% of total production. <br />Chorispora tenella accounted for 27.46 g/mz total production. Mnual forbs (including <br />Chorispora tenella) produce,i 33.38 g/m2 to represent 17.3% of the total herbaceous <br />production. Table 20 contains herbaceous production results for this treatment. <br />39 <br />
