saltbush, and intermediate wheatgrass with 18.4%, 13.9%, and 2.6% average cover, respectively. This <br />unit fails the revegetation success critedon of 90% of the Shadscale Reference Area value when both <br />annual and perennial cover values are combined. However, it passes when only perennial cover is <br />compared. <br />The 2002 Seeding of the Cameo RDA No. 1 currently passes only two of the four diversity <br />standards. There is sufficient cover of perennial cool-season grasses to pass the required minimum <br />values, and there are no planted species with greater than 70% relative cover. However, the present <br />relative cover of perennial warm-season grasses (0.25%) and perennial forbs or sub-shrubs (0%) is <br />insufficient to pass the required minimum values (2.0% and 0.5%, respectively). <br />3.14 Cameo RDA No. 2 - 2002 Seeding <br />Ground cover of the 2002 Seeding of the Cameo RDA No. 2 consisted of 39.1% live vegetation, <br />10.5% rock, 31.4% litter, and bare soil exposure of 19.0%. Perennial cover across the unit averaged <br />15.4% (down from the 29.2% observed in 2001 from the RDA slopes) with annual and biennial cover <br />averaging 23.7% (up from 15.1% in 2001 -also from the slopes). Dominant taxa were cheatgrass, <br />founving saltbush, and greasewood with 23.1%, 11.2%, and 2.8% average cover, respectively.

Perennial cover across the unit averaged 10.1% (down slightly <br />from 10.3% in 2004) with annual and biennial cover averaging 26.5% (up from 7.3% in 2004). <br />Dominant taxa were cheatgrass, fourwing saltbush, and snakeweed with 25.4%, 4.2%, and 2.3% <br />average cover, respectively.
