3.3 #3 - Roadside SP Liaht Use Road #1 (South) <br />Ground cover of monitoring area #3 - Roadside SP Light Use Road #1 (South) consisted of 78.6% <br />live vegetation, 5.2% rock, 6.4% litter, and bare ground exposure of 9.8% (Table 3). Perennial cover <br />across the unit averaged 3.9% with annual and biennial cover averaging 74.7 %. Dominant taxa were <br />cheatgrass, annual wheatgrass, and thickspike wheatgrass (Elymus /anceo /atus var. /anceo /atus) with <br />68.7 %, 3.6 %, and 2.4% average cover, respectively. Current total herbaceous production in monitoring <br />area #3 - Roadside SP Light Use Road #1 (South) totaled 830 pounds per acre with perennials <br />contributing 73 pounds per acre (Table 5). Woody plant density averaged 89 shrubs per acre and was <br />dominated by four -wing saltbush with occasional greasewood and Wyoming big sagebrush (Table 6). <br />This unit passes the two cool- season grass diversity standards and the total herbaceous production <br />standard (Table 1). Qualitative analysis indicates that this revegetated area exhibits poor overall <br />condition and aside from a small cool - season grass component, is nearly all cheatgrass. Monitoring area <br />#3 - Roadside SP Light Use Road #1 (South) will possibly require remediation to successfully pass <br />revegetation standards during the expected bond release timeline. Remediation might include herbicide <br />treatment (Plateau) of the cheatgrass stand followed by supplemental seeding. <br />3.4 #4 - Substation A <br />Ground cover of monitoring area #4 - Substation A consisted of 55.5% live vegetation, 4.4% rock, <br />25.1% litter, and bare ground exposure of 15.0% (Table 3). Perennial cover across the unit averaged <br />12.8% with annual and biennial cover averaging 42.7 %. Dominant taxa were cheatgrass, four -wing <br />saltbush, and thickspike wheatgrass with 40.4 %, 6.7 %, and 4.3% average cover, respectively. Current <br />total herbaceous production in monitoring area #4 - Substation A totaled 529 pounds per acre with <br />perennials contributing 352 pounds per acre to the total (Table 5). Woody plant density was 285 shrubs <br />per acre comprised mostly of four -wing saltbush (Table 6) with greasewood and shadscale scattered <br />throughout the unit. <br />This unit passes six of the ten revegetation standards, failing the warm- season grass diversity, <br />woody plant density, and total herbaceous production standards (Table 1). Qualitative analysis indicates <br />the revegetation in this unit is in average condition overall. However, shrub density, forb establishment, <br />and warm - season grass populations are limited in monitoring area #4 - Substation A. <br />3.5 Greasewood Reference Area <br />The Greasewood Reference Area was established as a new comparison area in 1999 and is located <br />adjacent to the BLM Bookcliffs access road and an ephemeral drainage.
