are no planted species with greater than 70% relative cover. However, the present relative cover of <br />perennial warm-season grasses (1.7 %) and perennial forbs or sub-shrubs (0%) is insufficient to pass the <br />required minimum values (2.0% and 0.5%, respectively). This unit has shown improvement, however, <br />from the last sampling effort in 2006, when the relative cover of perennial, warm-season grasses was <br />0%. <br />Qualitative analysis indicates that the Cameo RDA No. 1 area is in average condition overall. This <br />area displays great diversity between species and layering of vegetation. Grass diversity is excellent <br />within this unit. The invasive weed jointed goatgrass (Cylindropyrum cylindricum) was observed on the <br />east portion of the unit. <br />3.9 Cameo RDA No. 2 - 2002 Seeding <br />Ground cover of the 2002 seeding of the Cameo RDA No. 2 consisted of 53.3% live vegetation, <br />14.9% rock, 14.4% litter, and bare soil exposure of 17.4% (Table 3b). Perennial cover across the unit <br />averaged 25.3% (up from 15.4% in 2006) with annual and biennial cover averaging 28.0% (up from <br />23.7% in 2006). Dominant taxa were cheatgrass, fourwing saltbush, greasewood, and forage kochia <br />with 27.1%, 19.3%, 2.6%, and 2.0% average cover, respectively. <br />This unit passes the revegetation success criterion of 90% of the Shadscale Reference Area value <br />when both annual and perennial cover values are combined. It also passes when only perennial cover is <br />compared (Table 1). <br />The 2002 seeding of the Cameo RDA No. 2 currently passes only two of the four diversity standards. <br />There is sufficient cover of perennial forbs or sub-shrubs to pass the required minimum values, and there <br />are no planted species with greater than 70% relative cover. However, the present relative cover of <br />perennial warm-season grasses (0%) and perennial cool-season grasses (0%) is insufficient to pass the <br />required minimum values (2.0% and 0.5%, respectively). <br />Qualitative analysis indicates that the Cameo RDA No. 2 area is in average condition overall. Shrub <br />density and diversity was higher on the flat areas than the slopes. <br />3.10 Roadside Refuse Borrow <br />Ground cover of the Roadside Refuse Borrow Area consisted of 34.1% live vegetation, 3.1% rock, <br />31.3% litter, and bare soil exposure of 31.5% (Table 3b). Perennial cover across the unit averaged 8.4% <br />(up from 7.7% in 2006) with annual and biennial cover averaging 25.7% (down slightly from 25.9% in <br />CEDAR CREEK ASSOCIATES, Inc.
