3.1 #1 - Conveyor Crossing <br />Ground cover of monitoring area #1 - Conveyor Crossing consisted of 75.4% live vegetation, 0.0% <br />rock, 20.1% litter, and bare ground exposure of 4.5% (Table 3). Perennial cover across the unit <br />averaged 30.4% with annual and biennial cover averaging 45.0 %. Dominant taxa were cheatgrass <br />(Anisantha tectorum), four -wing saltbush (Atnp/ex canescens), and greasewood (Sarcobatus <br />vermicu /atus) with 40.1 %, 18.4 %, and 10.0% average cover, respectively. Current total herbaceous <br />production in monitoring area #1 - Conveyor Crossing totaled 665 pounds per acre with perennials <br />contributing 105 pounds per acre (Table 5). Woody plant density was 3,450 shrubs per acre and was <br />primarily comprised of four -wing saltbush and greasewood (Table 6). Shadscale (Atrip /ex confertifo /ia) <br />and Wyoming big sagebrush (Seriphidium tridentatum var. wyomingensis) were also occasionally <br />encountered within the unit. <br />This unit passes many revegetation success criteria excepting perennial grass diversity standards <br />and total herbaceous production (Table 1). Qualitative analysis indicates the revegetation in this unit is <br />in average condition overall. Shrub density and forb establishment are excellent throughout the unit; <br />however perennial grass populations are diminished. Aggressive invasive species, although not detected <br />in cover sampling, were observed invading from surrounding areas. These species include knapweed <br />(Centaurea sp.) and whitetop (Cardaria draba) on the south edge of the unit and jointed goatgrass <br />(Aegi /ops cy /indrica) along the road. <br />3.2 #2 - Roadside SP Liaht Use Road #1 (North) <br />Ground cover of monitoring area #2 - Roadside SP Light Use Road #1 (North) consisted of 38.6% <br />live vegetation, 34.9% rock, 13.4% litter, and bare ground exposure of 13.1% (Table 3). Perennial cover <br />across the unit averaged 15.1% with annual and biennial cover averaging 23.5 %. Dominant taxa were, <br />greasewood, cheatgrass, and annual wheatgrass (Eremopyrum triticeum) with 11.6 %, 7.9 %, and 7.7% <br />average cover, respectively. Current total herbaceous production across monitoring area #2 - Roadside <br />SP Light Use Road #1 (North) totaled 531 pounds per acre with perennials contributing 44 pounds per <br />acre (Table 5). Woody plant density averaged 3,950 shrubs per acre and was dominated by greasewood, <br />shadscale, and four -wing saltbush (Table 6). <br />This unit passes six of the ten proposed revegetation success criteria (Table 1). The standards not <br />successfully met are: the warm - season grass diversity standards, one cool- season grass standard, and <br />total herbaceous production. Qualitative analysis indicates that monitoring area #2 - Roadside SP Light <br />Use Road #1 (North) has excellent shrub establishment and promising perennial forb growth, but has few <br />perennial grasses. Annual species still dominate the area, but odds are reasonable they will diminish over <br />the next several years. <br />CEDAR CREEK ASSOCIATES, Inc. <br />Page 17 Snowcap - Revegetation Evaluation - 2011 <br />Monitoring <br />
