cam.�c a.�nc <br />Cedar Creek Associates, Inc. (Cedar Creek) conducted an equivalency comparison between the Aspen <br />community in the Danforth Study Area and Collom Aspen Reference Area (2005). This comparison occurred <br />as Colowyo cannot control nor manage the Aspen Reference Area (1984) in a manner consistent with the <br />approved post mine land use throughout the bond liability period (Rule 3.02.3). This is because the Aspen <br />Reference Area (1984) is located on BLM property not controlled by Colowyo [Rules 4.15.7(3)(ii) and <br />4.15.7(3)(d)]. Therefore, Colowyo cannot use the Aspen Reference Area (1984) to demonstrate <br />revegetation success for South Taylor reclamation. Based on the success of demonstrating comparability <br />to the Aspen Community in the Danforth Baseline Study, Colowyo will use the Collom Aspen Reference <br />Area (2005). The table below demonstrates that the Collom Aspen Reference Area (2005) is a suitable <br />replacement, as it shows comparability for both total cover and production against the Danforth Baseline <br />Study. <br />Reference Area Statistical Comparison <br />Danforth Baseline vs. <br />Collom Aspen RA <br />Danforth <br />Baseline <br />Collom RA <br />(2005) <br />PASS/ <br />FAIL <br />Total Cover <br />Estimated Mean (% cover) <br />Sample Variance <br />Sample Size Collected <br />Pooled Variance <br />Calculated t -statistic (t*) <br />Tabular Value fort 0.95,n1 +n2-2 <br />66.9 <br />149.1 <br />15 <br />72.1 <br />62.6 <br />20 <br />PASS <br />6.62 <br />4.96 <br />1.5035 <br />2.0345 <br />Production <br />Estimated Mean (g/m7) <br />Sample Variance <br />Sample Size Collected <br />Pooled Variance <br />Calculated t -statistic (t*) <br />Tabular Value fort 0.95 n1+n2-2 <br />129.1 <br />1236.7 <br />13 <br />124.4 <br />924.5 <br />30 <br />PASS <br />78.14 <br />33.86 <br />0.4522 <br />2.0195 <br />1 <br />
