3. The reclamation standards (90°6 of the acreage weighted means) were <br />compazed to the reclaimed azea means. If the reclaimed area mean is <br />greater than the adjusted mean then the azea is adequately reclaimed for that <br />parameter. <br />The results of the statistical evaluations using the described steps on each <br />parameter required are provided in Table 7. This data indicates that the reclamation <br />on the H-G Mine is acceptable under all cover and production pazameters analyzed for <br />the 1996 sampling yeaz. <br />The shrub density formula recommended by the CDMG was: <br />><=X^O <br />Sx <br />Where: <br />4 = Calculated t Value <br />X = Sample Means <br />Q = 90 % of the Standard (180) <br />Sx = Standard Error of Mean <br />This formula was used to determine if the shrub density standazd of 200 stems per <br />acre was met even though the data collected did not meet sample adequacy. This <br />formula is cone-tailed t-test evaluated at 90% percent co~dence and the results <br />demonstrated that the standard of 200 stems per acre was indeed met. <br />7.0 SUMMARY <br />The fact this reclaimed azea met the required statistical criteria for all cover, <br />production and shrub density parameters shows the area has been adequately reclaimed <br />for those parameters. Species diversity appears to be good and approaches that of the <br />18 <br />
