Species diversity success was determined from vegetative cover data. The species diversity success <br />standard on rangeland areas of the Trapper mine consists of a minimum of four cool season perennial <br />grass species and one forb species. Each of the contributing species needs to contribute at least 3 <br />percent relative cover but no more than 50 percent relative cover. No four species may contribute <br />greater than 80 percent relative cover. The table included below shows that each of the bond release <br />blocks meet these criteria. <br />The woody plant density (WPD) success standard is composed of two components. The first <br />component is comprised of 400 stems per acre measured during the cover data collection. The <br />second component is comprised of concentrated shrub clumps. Three shrub clumps, SC-A-94, SC-D- <br />94 SC-H-94, were included in the lands requested for Phase III bond release. The shrub clumps are <br />composed of transplanted shrub pads. If pads exhibit 10 or more live shrubs per pad, the pad is <br />considered alive. Iffifty-percent or more of the shrub pads within a clump are considered alive, the <br />clump is considered successful. The 2004 sample data found 77.4% live pads within the clumps, <br />white the 2005 sample data recorded 77.2% live pads within the clumps. The shrub clumps and <br />woody plant densities were considered successful for A, D& H Pits RS A&B 93-95 bond release <br />block. This is the only bond release block in the SL-07 application that has a woody plant density <br />standard. <br />Bond Release Blocks Species >3% but Top 4 species rel.

Although considered a species of concern <br />throughout the western United States, Columbian Sharptail Grouse have returned in healthy numbers to <br />the reclaimed rangelands on the mine site and have reestablished stmtting leks. <br />Trapper Mine, SL-07 Findings 8 May 16, 2006 <br />
