3.0 RESULTS <br />Tabular compilations of raw data and summaries for the aforementioned sampling efforts are <br />presented in Appendix A on Tables 2 through 7 and Charts 8 and 9. Summaries of the success <br />comparison for the two units individually are provided on the following pages in Table 1 and Charts 1 <br />through 7. Table 1 gives a quick indication of the overall success of the revegetation units compared <br />with reference area data and /or standards. Charts 1 through 7 provide a visual display of the same <br />comparisons. <br />With regard to perennial lifeform ground cover, Substation G passed the success criterion (90% of <br />the reference area value) with 24.0% cover, whereas the CDRA #1 Road and Top does not pass with <br />5.4% cover. Both of these units should exhibit increased perennial cover as both grasses and shrubs <br />mature in the coming years. With regard to diversity, both revegetated areas passed the four relative <br />cover standards, achieving a relative cover of >_0.5% for perennial cool - season grass species, >_0.5% for <br />perennial warm - season grass species, and >_0.5% for forbs and suffrutescent (sub- shrub) species, as well <br />as not having a single species that represents > 70% relative cover. Both units passed the standards of <br />having at least two perennial cool- season grass species and two perennial forb and subshrub species <br />present. However, both units failed the standard of having at least two perennial warm- season grass <br />species present, with only a single species observed in each unit. A more extensive evaluation of these <br />units in future monitoring efforts will likely reveal additional warm- season grass taxa. An evaluation of <br />the remaining variables of production and woody plant density was not undertaken in 2013 due to the <br />youth of the revegetation. <br />3.1 CDRA #1 Road and Top <br />Ground cover of the CDRA #1 Road and Top consisted of 36.1% live vegetation, 4.6% rock, 26.7% <br />litter, and bare ground exposure of 32.6% (Table 3). Perennial cover across the unit averaged 5.4% with <br />annual and biennial cover averaging 30.7% and noxious weed cover averaging 0.0 %. Dominant taxa <br />were annual wheatgrass (Eremopyron triNceum), cheatgrass (Anisantha tectorum), and saltlover <br />(Haiogeton giomeratus) with 18.7 %, 4.2 %, and 2.7% average cover, respectively. <br />This unit passed most of the revegetation success comparisons excepting plant cover of perennial <br />lifeforms and the diversity standard of the number of perennial warm- season grass species present <br />(Table 1). This unit is exhibiting fair to good revegetation after four years with the flat reclamation on <br />top showing better perennial plant germination than the slopes. Annual grasses are still the dominant <br />lifeform although patches of grasses and shrubs are emerging. With favorable precipitation patterns, <br />CEDAR CREEK ASSOCIATES, Inc.
