• herbaceous cover and up to 19% litter. Examination of Table 5, Rangeland Reclamation Block AD&H- <br />AB-93-95 -Plant Cover, reveals that the total "allowable cover" on this site averaged 65. 11 percent. <br />Since the actual "allowable cover" value (65.11 %) for this reclaimed site excceds the revegetation <br />success standard for this site (52%), it can be concluded that the "allowable cover" in this reclamation <br />block satisfies the revegetation success standard. <br />Perennial grasses dominated the seeded vegetation on this site. Western Wheatgrass, Intermediate <br />Wheatgrass, Smooth Bromegrass, and Great Basin Wildrye were the most wmmonly encountered <br />grasses, contributing 12.62, 12.24, 6.65 and 4.05 percent, respectively, of the total relative cover found on <br />this site. Alfalfa and Cicer Milkvetch were the most commonly enwuntered perennial forbs on this site, <br />wntributing 16.28 and 6.26 percent of the total relative cover, respectively. <br />The locations of the 20 cover transecsts sampled on this site are shown on Map 2, Rangeland <br />Reclamation -Vegetation Transect Location Map. Copies of the individual field data sheets for the plant <br />cover sampling of this site are found in Exhibit C -Copies of Rangeland Reclamation Block AD&H-AB- <br />93-95 -Plant Cover Field Data Sheets. The sample adequacy calculations in Table 2, Trapper Mine <br />Sample Adequacy Calculations, document that the number of samples required to describe this site at the <br />90 percent confidence interval was detemvned to equa13.2 samples. <br />Production. The results of the 30 production transects on this area are summarized in Table 6, Rangeland <br />Reclamation Block AD&H-AB-93-95 -Production. The average forage production on this site averaged <br />137.35 gN2mz. Perennial grasses contributed 95.17 g/1/2m2 or 69.29 percent and perennial forbs, <br />contributed 42.18 g/1l2m2 or 30.71 percent of the forage production on this area The revegetation <br />• forage production success standard for this area is 62.39 g/mZ. Since this site averaged 274.70 g/mZ, it <br />can be concluded that this area satisfies the revegetation success standard with respect to forage <br />production. <br />The locations of the 30 production hansects sampled on this site are shown on Map 2, Rangeland <br />Reclamation -Vegetation Trat~sect Location Map. Copies of the individual field data sheets for the <br />forage production sampling of this site are found inExhibit D -Copies of Rangeland Reclamation Block <br />AD&H-AB-93-95 -Production Field Data Sheets. The sample adequacy calculations in Table 2, <br />Trapper Mine Sample Adequacy Calculations, documents that the number of production iransects <br />required to characterize this site at the 90 percent confidence interval was 51.2. Since the reclaimed area <br />production value (274.70 gJmz) excceds the revegetation success standard of 62.39 g/mZ with 30 <br />transects, as allowed in the DMG's proposed reverse null approach, it can be concluded that this area was <br />sufficiently sampled with reslxct to forage production. <br />Shrub Deusilv. The shmb density counts obtained from the 30 belt tiar>.sects taken in this area are <br />swnrnarized in Table 7, Rangeland Reclamation Block AD&H-AB-93-95 - Shmb Density. The average <br />shrub density was detemvned to equa120.70 shnrbs per one hundred square meters or 837.7 shrubs per <br />acre. Bitterbrush, Mountain Snowbeny, and Big Sagebnrslr were the most commonly enwuntered <br />shrubs. The revegetation shnrb density success standard for this area is 400 stems per acre. Since this site <br />averaged 837.7 stems per acre, it can be concluded that this area satisfies the revegetation success <br />standard with respect to shmb density. <br />• <br />
