Qualitative analysis indicates this revegetation is in average condition overall. Shrub density is <br />excellent throughout the unit; however forbs and grass populations are patchy. <br />3.2 Cameo Borrow Area No. 2 <br />Ground cover of the Cameo Borrow Area No. 2 consisted of 56.5% live vegetation, 6.9% rock, <br />21.4% litter, and bare soil exposure of 15.2% (Table 3a). Perennial cover across the unit averaged <br />25.8% (up from 22.1% in 2006) with annual and biennial cover averaging 30.7% (up from 22.1% in <br />2006). Dominant taxa were cheatgrass, fourwing saltbush, and forage kochia (Kochia prostrata) with <br />30.6%, 19.1%, and 4.3% average cover, respectively. <br />This unit passes the revegetation success criterion of 90% of the Greasewood 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 Cameo Borrow Area No. 2 currently passes only two of the four diversity standards. There is <br />sufficient cover of perennial forbs or sub-shrubs to pass the required minimum values, and there are no <br />planted species with greater than 70% relative cover. However, the present relative cover of perennial <br />warm-season grasses (0%) and perennial cool-season grasses (0.4%) is insufficient to pass the required <br />minimum values (2.0% and 0.5%, respectively). <br />Qualitative analysis indicates that the Cameo Borrow Area No. 2 was in fair to average overall <br />condition. Cheatgrass was pervasive throughout the area, contributing to minimal bare ground exposure <br />and a low vegetative diversity. <br />3.3 Cameo Topsoil Piles <br />Ground cover of the Cameo Topsoil Piles consisted of 64.1% live vegetation, 5.9% rock, 20.8% <br />litter, and bare soil exposure of 9.2% (Table 3a). Perennial cover across the unit averaged 29.4% (up <br />from 17.5% in 2006) with annual and biennial cover averaging 34.7% (down from 36.5% in 2006). <br />Dominant taxa were cheatgrass and fourwing saltbush with 33.1%, and 29.2% average cover, <br />respectively. <br />This unit passes the revegetation success criterion of 90% of the Greasewood 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 Cameo Topsoil Piles currently passes only one of the four diversity standards: there are no <br />planted species with greater than 70% relative cover. The present relative cover of perennial warm- <br />CEDAR CREEK ASSOCIATES, Inc. Page 17 Snowcap Coal Co. - 2008 <br />Revegetation Evaluation
