Hany Ranney <br />Mazch 1, 2002 <br />Page 4 <br />Post Mining Success Demonstration <br />Post mining demonstration of revegetation success for vegetative cover and herbaceous production <br />within the reclaimed areas will be determined through use of the One-Sample T-Test (Equation 3). <br />This statistical test is used only when the reclaimed area sample mean is less than 90 percent of the <br />reference azea mean value. <br />(3) <br />t = Q-x <br />Sx <br />Where: <br />k = Calculated t value <br />Q = 90% of the standard <br />x = Bond release block sample mean <br />s= = Standard error of the mean (s/fin) <br />s = Sample standard deviation <br />n = Sample size <br />The null hypothesis being tested is that the bond release block mean (u) is greater than or equal to <br />90% of the standazd (H°: u? Q). If k is less than or equal to the 1-tailed t table value for alpha error <br />probability of .10, at the appropriate degrees of freedom, then H° is not rej ected, and revegetation is <br />deemed successful for the parameter tested. <br />Species Diversity <br />The diversity ofplant species present in the three reclaimed areas and the two reference azeas will be <br />evaluated using data acquired from the point-intercept transects. Data from the transects will be <br />analyzed by implementing Equation 4 to determine the relative cover of each species detected. <br />
