<br />Woody plants were represented in cover sampling by three species. Atriplex <br />' confertifolia accounted for 5.2% mean and 17.6% relative cover. Atrip/ex canescens <br />represented 3.2% mean cover (10.5% relative cover), while Chrysothamnus vicidilllorus <br />' (Douglas Rabbitbrush) accounted for 0.4% mean cover and 1.39b relative cover. <br />Herbaceous Production <br />Total herbaceous production for the South Area was 64.40 g/m2 (573.16 lb/ac). <br />Bromus japonicas/tectorum dominated production with 31.90 g/mz and 49.5% of total <br />production. Agropyron cristalum accounted for the majority of perennial graminoid <br />production with 22.32 g/m2 representing 34.6% of total production. Medicago satires <br />was a minor contributor to production (0.54 glm2). Only one annual forb was present. <br />' Descurainia Sophia comprised 9.9% of total production. Table 26 wntains South Area <br />herbaceous production sampling results. <br />' Woody Plant Density and Dimensions <br />There were 34 woody plants counted on this plot for a density of 510/acre. Four <br />' species were present with Atrip/ex confertifolia dominating, followed by Atriplex <br />canesmns, Chrysothamnus nauseosus and Chrysothamnus vicidi6orus. The largest <br />' woody plant was an Atrip/ex canescens individual measuring 60 cm high by 73 cm in <br />diameter. <br />' Species Diversity <br />There were four lifeforms represented on this treatment plot. Perennial and annual <br />grasses were each represented by one species, annual (orbs by two species, and woody <br />plants by three species. Of these lifeforms, those representing greater than three <br />' percent relative cover included perennial and annual grasses each with one species and <br />annual forts with two species. <br />' 3.7 Shadscale Sbrubland Reference Area <br />Cover <br />' Sample adequacy for cover sampling was achieved after five samples in the Reference <br />Area. To secure additional representation of minor species within the Reference Area, <br />and additional five cover transects were taken. Sample adequacy was achieved with the <br />' ten cover transects also. Vegetation cover for the reference area was_36.0%;Of that <br />total, graminoids comprised 30.4% mean cover, forts 2.2°!o mean cover, succulents <br />0.2°l0, and woody plants 3.2°6 cover. Litter provided 22.8% total cover, rock 26.0%, <br />' and baze ground 15.2%. Table 27 presents cover results for this treatment. <br />43 <br />
