relative plant cover. <br />The locations of the 15 cover transects sampled on this site are shown on Map 5, 1999 <br />Reclamation - 2010 Vegetation Transect Location Map. The sample adequacy calculations in <br />Table 2, Marr Mine - 2010 Statistical Summary and Sample Adequacy Calculations, document <br />that the number of transects required to characterize the plant cover on this site at the 90 percent <br />confidence interval was 7.5 transects. <br />When IME sampled this site in 2005, total plant cover averaged 33.27 percent and litter cover <br />averaged 27.27 percent. When sampled in 2009, IlVIE reported that the total plant cover on this <br />site averaged 33.94 percent and litter cover averaged 34.41 percent. <br />Table 6, 1999 Reclamation - 2010 Plant Cover, documents that "total plant cover" on this <br />reclaimed site averaged 42.80 percent. Since this "total plant cover" value from this reclaimed <br />site exceeds the total plant cover value of 37.60 percent obtained from the sampling of the Alkali <br />Sagebrush Reference Area, then this value (37.60 %), would be the corresponding revegetation <br />success standard for the 1999 Reclamation site. Since sample adequacy was achieved for plant <br />cover sampling on both reference areas and this reclaimed site, and the "total plant cover" on the <br />reclaimed area exceeds the corresponding reference area standard, it can be concluded by direct <br />comparison that the "total plant cover" for the 1999 Reclamation Block satisfies the revegetation <br />success standard with respect to "total plant cover." <br />Production. The results of the 30 production transects sampled on this area are summarized in <br />Table 7, 1999 Reclamation - 2010 Production. This table shows that the average total herbaceous <br />forage production was found to be 42.34 g/1 /4 m or 1,509.0 pounds or air -dry forage per acre. <br />Perennial grasses contributed 40.92 g/1 /4 m or 96.65 percent of the herbaceous forage produced <br />on this area. Perennial forbs, contributed 1.42 g/1 /4 m or 3.35 percent of the herbaceous forage <br />production on this area. <br />The revegetation forage production standard for this area is 7.40 g/1 /4m or 263.7 pounds of air - <br />dry forage per acre which is the value obtained from the sampling of the Alkali Sagebrush <br />Reference Area. Since the 1999 Reclaimed site averaged 42.34 g/1 /4m or 1,920.2 pounds or <br />air -dry forage per acre, and this value exceeds that produced on the Alkali Sagebrush Reference <br />Area, it can be concluded by direct comparison that the 1999 Reclaimed site satisfies the <br />revegetation success standard with respect to total herbaceous forage production. <br />In 2005, HVIE reported that total herbaceous forage production on this site averaged 53.88 <br />g/IAm' or 1920.3 pounds of air -dry forage per acre. When sampled in 2009, IlVIE reported that <br />this reclaimed site produced a total of 30.81 g/1 /4m or 1,098.1 pounds of air -dry forage per <br />acre. <br />The locations of the 30 production transects sampled on this site are shown on Map 2, 1999 <br />Reclamation - 2010 Vegetation Transect Location Map. The sample adequacy calculations in <br />Table 2, Marr Mine - 2010 Statistical Summary and Sample Adequacy Calculations, document <br />that the number of samples required to describe this site at the 90 percent confidence interval <br />was 144.3 transects. <br />s <br />
