4.0 SUCCESS COMPARISON <br /> 4.1 Ground Cover <br /> A direct comparison between the Phase II bond release block and the weighted reference area <br /> data could be made because sample size adequacy was met in the Phase II sampling block (n=40, <br /> Nmin=20.52; Table 2). Chart 2 displays the results from ground cover sampling and reveals that the <br /> Phase II Bond Release Block exceeds the weighted reference area comparison with 39.78% herbaceous <br /> perennial cover versus the 14.36% herbaceous perennial cover standard (90% of 15.95%) (Table 2). <br /> Chart 2 <br /> as.00 <br /> Perennial Herbaceous Ground Cover-success Comparison <br /> 40.00 <br /> a, <br /> 35.00 <br /> C <br /> a <br /> 07 30.00 <br /> C <br /> 0 <br /> 25.00 <br /> a <br /> = 20.00 <br /> m <br /> c <br /> 15.00 <br /> at <br /> a <br /> v 10.00 <br /> a, <br /> a <br /> 5.00 <br /> 0.00 son <br /> Phase II Success Standard Weighted Reference Area Mtn Shrub R.A.
