4.2 Diversity <br />Colowyo's proposed diversity standard for older reclamation is replacement of 2 perennial grasses <br />with between 3% and 50% relative cover (composition) and total perennial forb relative cover between <br />1% and 50% in each target reclamation unit. As indicated on Charts 5 & 6 and Table 7 evaluation of <br />diversity on the Phase III bond release area revealed 7 perennial grasses (between 3% and 50% relative <br />cover) and perennial forb composition of 22.1 %. <br />In Summary, Phase III areas addressed by this document strongly surpass the success <br />standard for diversity. <br />4.3 Woody Plant Densi <br />According to TR -72, the woody plant density success criterion within pre -2008 reclamation at <br />Colowyo's operations is proposed to be 150 live stems oer acre on approximately 3% (or more) of the <br />reclaimed surface. Tables 5 and 7 and Charts 7 and 8 display the results from the woody plant <br />populations enumerated in 2006 and 2008 on Phase III bond release areas. Based on evaluations to <br />date (10 of 11 shrub patches that account for 16.8 of 17.13 acres) shrub density has been determined to <br />be an average of 879.7 stems per acre. The acreage of these shrub patches is 8.4% of the total acreage <br />assessed for Year 1 - Phase III evaluations. In addition, table 6 displays the results from woody plant <br />density belt transects collected at each sample point in 2008. Perusal of this table reveals that an <br />average of 148.4 woody plants per acre were encountered in the non - shrubland portion of the Phase III <br />bond release area. <br />In Summary, Phase III areas addressed by this document pass the success standard for <br />woody plant density. <br /> 0• <br />Cedar Creek Associates, Inc.
