value of 732.5 woody stems per acre surpassed the required 90 stems per acre in the <br />"background" reclamation area. PSC measured 2703.3 stems per acre in concentrated <br />shrub areas within BRB in 2011. The concentrated shrub areas comprised 229.2 acres, or <br />22.3% of the BRB acreage. Woody stem density did not achieve sample adequacy in the <br />concentrated shrub areas in 2012, but PSC collected a minimum of 50 transects, and <br />conducted a reverse -null calculation to validate the 2011 concentrated shrub success. <br />The Division fmds the data and calculations acceptable, and fmds the woody stem density <br />establishment successful for 2011 in the BRB. <br />Species Diversity <br />PSC uses four different tests to determine species diversity success. The first test A, is <br />mandatory, and requires that no single plant species may exceed 60% relative cover. <br />Two of the remaining tests, B, C, or D must be met to achieve diversity success. For <br />2010 vegetation data the BRB was successful for tests A, C, and D. The Division finds <br />the 2010 data successful for species diversity. The 2011 vegetation data for the BRB was <br />successful for tests A, C, and D. The Division finds the 2011 data successful for species <br />diversity. <br />
