this site, contributing 20.05, 13.28 and 10.27 percent, respectively, of the total relative cover on <br />this area. <br />When IME sampled this site in 2005 total plant cover was determined to equal 25.27 percent. <br />The locations of the 15 cover transects sampled on this site are shown on Map 3, Tipple <br />Reference Area - Vegetation Transect Location Map. The sample adequacy calculations in <br />Table 2, Kerr Mine Sample Adequacy Calculations, document that the number of vegetation <br />transects required to characterize the total plant cover on this site at the 90 percent statistical <br />confidence interval was 11.6 transects. <br />Production. The results obtained from the sampling of the 30 production transects on Tipple <br />Reference Area are presented in Table 11, Tipple Reference Area - Production. Total herbaceous <br />forage production on this location averaged 4.64 g/l /4m Perennial grasses averaged 3.26 <br />g/1 /4m and contributed 70.26 percent of the total herbaceous forage and perennial forbs, <br />contributed an average of 1.38 g/1 /4m or 29.74 percent of the forage produced on this site. No <br />annuals or noxious weeds were encountered in the productions sampling of this site. <br />When IME sampled this site in 2005, they reported that total herbaceous forage production <br />averaged 3.78 g/1 /4m or 134.7 pounds of air -dry forage per acre. Perennial grasses contributed <br />2.90 g/1 /4m or 76.72 percent of the total forage production and perennial forbs contributed 0.01 <br />g/1 /4m or 23.28 percent of the total forage production <br />The locations of the 30 production transects sampled on this area are shown on Map 3, Tipple <br />Reference Area - Vegetation Transect Location Map. Examination of Table 2, Kerr Mine <br />Sample Adequacy Calculations, reveals that sample adequacy at the 90 percent confidence <br />interval was equal to 11.6 transects. <br />Species Diversity. The forage quality index calculations for this site are found in Table 12, <br />Tipple Reference Area - Forage Quality Index Calculations. An exact copy of this table was <br />submitted by KCC in connection with TR -25. As are documented in these calculations, the <br />forage quality index value for the Tipple Reference Area at the Marr Mine as sampled in 2009 is <br />210.18. <br />TIPPLE RECLAMATION <br />Plant Cover. The results obtained from the sampling of the 20 plant cover transects on this site <br />are presented in Table 13, Tipple Reclamation - Plant Cover. Total plant cover on this site <br />averaged 32.85 percent and litter averaged 25.45 percent (Table 13, Tipple Reclamation - Plant <br />Cover). <br />Seeded cool season perennial grasses were the most dominant plant life form encountered in the <br />vegetation sampling of this site and contributed a total of 16.10 percent of the total cover and <br />49.02 percent of the total relative cover on this site. Seeded and invading shrubs and subshrubs <br />were the second most dominant plant life form on this site contributing 9.75 percent of the total <br />cover or 29.68 percent of the total relative cover on this reference area. Perennial forbs were the <br />10 <br />
