• choice, the reclaimed areas would qualify for bond release. For cover, the total <br />herbaceous cover mean of 39.8% dearly exceeds 36.0%. Table 9 demonstrates that <br />the 35.7% perennial, non-noxious cover mean is also equivalent to the target standard <br />with 90% statistical confidence. For herbaceous production, both the total and the total <br />perennial, nun-noxious values of 2414 and 2294 pounds per acre respectively exceed <br />the target value of 1440. <br />Table 4 shows that no species exceeds the 60% relative cover cutoff value. <br />Seven species contribute greater than 3% relative cover. Four are caul season grasses <br />(E[ymus truc'hycuulis, Lophopyrum clongutunt, Puscapyrum smithir, and Pou prutensis), <br />two are perennial ti~rbs (Astrugulus cicer and Eucephulus glaucus), and one is the <br />biennial forb Me[itotus ofjicinutis. Combined, the six perennial species add up to less <br />than 80% cover, the maximum allowable value for hre species. Therefore, the cover <br />• data indicates that the site has exceeded the species diversity success requirements. <br />Sample Adequacy Calculations: <br />On August 11, all cover vansects were sampled. Sample adequacy for those <br />transacts was calculated to be 17.0. Therefore, since the number of transacts sampled <br />(19) exceeds the calculated sample adequacy value, the mine area can he considered to <br />have been adequately sampled for this parameter. Table 7 summarizes the calculation <br />of the cover sample adeyuacy value. <br />Between August 12 and 14, 120 production plots were clipped. These samples <br />were allowed to air-dry for a week and were then weighed in order [u allow a <br />preliminary calculation of sample adequacy. The sample adeyuacy value t<~r the 120 <br />samples was 152.0, requiring that additional production samples he collected. On <br />August 19, the site was again 'visited, with an additional 35 samples being collected in <br />• order to satisfy sample adeyuacy requirements. The preliminary sample adeyuacy <br />value calculated for the combined 155 samples was 131.4, indicating that adeyuacy had <br />7 <br />
