Table 13, 1996 Reclamation -Plant Cover, <br />documents that the "total plant cover" on the 1996 reclamation averaged 38.13 percent. Since <br />this "total plant cover" value exceeds the revegetation success standazd (31.56 %), and sample <br />adequacy was achieved for plant cover for the two reference areas and this reclaimed site, it can <br />be concluded by direct wmparison that the "total plant cover" for the 1996 Reclamation Block <br />satisfies the revegetation success standard with respect to "total plant cover." <br />Perennial cool season grasses dominated the seeded vegetation. Russian Wildrye and Western <br />Wheatgrass were the most commonly encountered grasses on this site, contributing 29.89 and <br />9.62 percent, respectively, of the total relative cover on this area. The most dominant forb <br />species growing on this site was Lewis Flax which contributed 10.32 percent of the total relative <br />plant cover. The most dominant shrub was Wyoming Big Sagebrush which wntributed 5.77 <br />percent of the total relative cover on this reclaimed site. <br />When ESCO sampled this site in 1999, they reported that the total plant cover averaged 32.5 <br />percent and the four do*ninant species were Westem Yarrow, Lewis Flax, Flixweed <br />Tandymustard and Small Bumet which contributed 38.41, 28.26, 7.61 and 5.43 percent, <br />respectively, of the total relative cover on this site. In the 2005 sampling, total plant cover on this <br />site averaged 32.73 percent. <br />The locations of the 15 cover transects sampled on this site are shown on Map 5, 1996 <br />Reclamation -Vegetation Transect Location Map. Copies of the individual field data sheets for <br />the plant cover sampling of this site are found in Appendix L - Copies of 1996 Reclamation - <br />Plant Cover Field Data Sheets. The sample adequacy calculations in Table 2, Man Mine Sample <br />Adequacy Calculations, document that the number of transects required to describe this site at <br />the 90 percent confidence interval was 9.5 samples. <br />• Production. The results of the 30 production transects sampled on this area are summarized in <br />Table 14, 1996 Reclamation -Production This table shows that the average total herbaceous <br />forage production on this site equaled 21.31 g/1/4 mZ or 759.5 pounds of air dry forage per acre <br />Perennial grasses contributed 16.13 g/1/4 m' or 75.69 percent of the herbaceous forage produced <br />on this area. Perennial forbs, contributed 5.11 g/1/4 mz or 23.98 percent of the herbaceous forag <br />production on this area and annuals, contributed 0.07 g/1/4 m2 or 0.33 percent of the herbaceous <br />forage production on this area. <br />In the 2005 sampling of this reclaimed site, total herbaceous forage production was found to <br />average 37.90 g/1/4 m2 1,350.8 pounds of air-dry forage per acre. <br />e <br />The revegetation forage production standard for this area is 6.11 g/1/4m2. Since this site <br />averaged 19.18 g/1/4mZ, this area satisfies the revegetation success standazd with respect to total <br />herbaceous forage production. <br />The locations of the 30 production transects sampled on this site are shown on Map 5, 1996 <br />Reclamation -Vegetation Transect Location Map.
