Achieve annual herbaceous production levels of >_ 90% of 400 pounds per acre (360). <br />Achieve the same species diversity standards as the West Mine Unit. <br />Success evaluations involve a direct comparison and, where necessary, statistical testing of the ground <br />cover parameter. A total of perennial, biennial and annual (non- noxious) vegetation cover is stated as the <br />approved success standard, however there is a limitation to the amount of annual and biennial cover that <br />can be included in this total. According to guidance provided by CDRMS, annuals and biennials can only <br />contribute 10% relative cover to the comparison. Implementation of this method initially requires noxious <br />weeds to be removed from total cover. Next, annual and biennial absolute cover must be converted into <br />relative cover. Any annual and biennial cover exceeding 10% relative cover must be removed from the <br />total cover data set. The result of this calculation is absolute perennial cover with 10% allowable relative <br />cover of annual and biennial vegetation. The resulting data can then be used in a direct comparison against <br />a standard. <br />In 2013, Cedar Creek was able to make direct comparisons between the Phase II sampling effort and <br />standard (because of statistically adequate sampling), thus a standard statistical t -test was not required. <br />CEDAR CREEK ASSOCIATES, INC.
