• Species Diversity PCC evaluated the species diversity success standard during 2001. The evaluation, presented in Appendix 14-7, also recommends a remedial revegetation treatment for CRDA-2. In accordance with the evaluation, PCC will apply remedial revegetation treatments, during November 2001, to the south and west facing slopes of CRDA-2 which appear unlikely to meet final success criteria. The following species diversion standard is based on the evaluation and consultation with the DMG: Item Relative Cover - Total perennial cool season grass species > 0.5 % - Total perennial warm season grass species > 2.0 % - Total perennial (orbs and suffrutescent species > 0.5 % - No reclaimed azea shall have a single species that represents > 70 % Revegetation Success Reference Areas The baseline vegetation study taken in 1982 and included in Appendix 10- • 1, Tab Section 10, established 3 reference areas. These areas aze shown on Exhibit 49 and include a west facing hillside designated as a Shadscale reference area, a drainage bottom designated, as a Greasewood reference area and a southwest facing hillside and drainage bottom designated as a Greasewood/Shadscale reference area. During construction of CRDA 2, a major portion of the GreasewoodJShadscalereferevice area (primarily the Shadscale vegetation type) was disturbed and is no longer available for comparison purposes. The remaining portion, approximately 6 acres, represents the Greasewood vegetation type which occurs in the upland drainage of the permit area. A new reference azea was established during 1999 which represents the Greasewood vegetation type. This reference area is located approximately 1,500 feet northwest of the Cameo Refuse Disposal Area No. 1 along the east-facing colluvial toe slope adjacent to the BI1vI Bookcliffs access road and the ephemeral drainage. • 14-24 (Rev. 10/01) "jQ <38"
