The locations of the 30 shrub density transects sampled on this site are shown on Map 2, Trapper <br />Mine - Vegetation Transect Area (D-Pit), Map 3, Trapper Mine - Vegetation Transect Area (H- <br />Pit) and on Map 4, Trapper Mine - Vegetation Transect Area (A-Pit). Copies of the individual <br />field data sheets for the woody plant density sampling of this site are found in Exhibit C - Copies <br />of Rangeland Reclamation Block AD&H-AB - 96-98 - Shrub Density Field Data Sheets. <br />Examination of the sample adequacy calculations in Table 2, Trapper Mine Sample Adequacy <br />Calculations, reveals the number of samples required to describe the shrub density on this area at <br />the 90 percent confidence interval was 123.1 transects. Since the actual shrub density counts on <br />this reclaimed site (771.6 stems per acre) exceeds the approved standard (400 stems per acre), <br />using Section 4.15.11(2) of the Division's regulations, monitoring requirements are achieved <br />using the reverse null equation with 30 transects. <br />Species Diversity. The percent relative composition or cover values in Table 3, Rangeland <br />Reclamation Block AD&H-AB - 96-98 - Plant Cover, documents a total of seven perennial <br />species possessing a relative cover of greater than 3 percent. Included in this number are five <br />cool season perennial grasses and two species of perennial forbs. <br />The revegetation success standard for species diversity for these revegetated areas is that they <br />are to be dominated by a minimum of at least four cool season perennial grasses and one forb <br />species each possessing at least 3 percent relative cover. On this reclaimed site, there are five <br />cool season grasses and two forb species, which satisfy this species diversity standard. The <br />Permit requires that the maximum allowable contribution by a single species cannot exceed 50 <br />percent relative cover and no four species can contribute more than 80 percent of the relative <br />cover. Application of these criteria documents that the maximum contribution in terms of <br />relative cover for a single species is 16.38 percent with the four most dominant species on this <br />site contributing only 52.31 percent of the total relative cover on this site. The revegetation. <br />monitoring data from this site confirm that the species diversity standards for this area have been <br />satisfied. <br />SHRUB CLUMP EVALUATION <br />A total of three shrub clumps, which are located in Rangeland Reclamation Block AD&H-AB - <br />96-98, were sampled to determine if at least half of the pads within these clumps possessed at <br />least ten live shrub stems per pad. The locations of the three shrub clumps evaluated are shown <br />on the enclosed maps. Two shrub clumps, (SC-D-98 and SCD-99) are shown on Map 2, Trapper <br />Mine - Vegetation Transect Area (D-Pit) and the location of the third shrub clump evaluated <br />(SC-A-99) is shown on Map 4, Trapper Mine - Vegetation Transect Area (A-Pit). The results of <br />this sampling are summarized in Table 6, Shrub Clump - Shrub Survival Summary. <br />The revegetation success standard is for at least half of the transplanted shrub pads to possess 10 <br />live woody plant stems or more. As soon as at least half of the pads had been counted, it was <br />possible to determine whether this standard had been satisfied. As summarized in this table, the <br />survival of shrubs in these individual clumps ranged from 23.81 percent to 96.15 percent with an <br />overall average of 67.09 percent. <br />Copies of the individual field data sheets used to calculate the shrub density for the Shrub <br />Clumps are found in Exhibit D - Copies of Shrub Clump - Shrub Survival Field Data Sheets. <br />6
