Species Diversity. The forage quality index calculations for this site are found in Table 12, <br />Tipple Reference Area - 2010 Forage Quality Index Calculations. An exact copy of this table <br />was submitted by KCC to the CDRMS in connection with TR -25. The forage quality index <br />value for the Tipple Reference Area as sampled in 2010 equaled 189.23 <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 - 2010 Plant Cover. Total plant cover on this site <br />averaged 39.67 percent and litter averaged 35.80 percent (Table 13, Tipple Reclamation - 2010 <br />Plant Cover). <br />Seeded cool season perennial grasses were the most dominant plant life form encountered and <br />contributed a total of 17.87 percent of the total cover and 45.05 percent of the total relative cover <br />on this site. Seeded and invading shrubs and subshrubs were the second most dominant plant <br />life form on this site contributing 11.00 percent of the total cover or 27.73 percent of the total <br />relative cover on this reference area. Perennial forbs were the third most dominant plant life <br />form and contributed 8.53 percent of the total plant cover or 121.51 percent of the total relative <br />cover on this site. Annuals and biennials were the third most common plant life form <br />encountered, and contributed 2.07 percent of the total plant cover or 5.21 percent of the total <br />relative plant cover found on this site. <br />Russian Wildrye was the most dominant grass plant species encountered on this site followed by <br />Great Basin Wildrye which contributed 9.24 and 7.39 percent, respectively, of the total relative <br />cover found on this site. Shrubs were found to be the subdominants on this site, with Rubber <br />Rabbitbrush and Wyoming Big Sagebrush being the most commonly encountered shrubs on this <br />site, contributing 18.99 and 6.55 percent of the total relative cover, respectively. Forbs were <br />found to be the least abundant life form on this site, with Western Yarrow and Cicer Milkvetch <br />being the most commonly encountered perennial forbs on this site, contributing 10.08 and 6.89 <br />percent of the total relative cover, respectively. <br />When HAE sampled this site in 2005 total plant cover averaged 29.24 percent and litter averaged <br />30.04 percent. The 2009 sampling of this site, revealed that total plant cover averaged 32.85 <br />percent and that litter averaged 25.45 percent. <br />The locations of the 15 cover transects sampled on this site are shown on Map 4, Tipple <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 vegetation transects required to characterize the total plant cover on this site <br />at the 90 percent statistical confidence interval was determined to equal 13.2 transects. <br />The revegetation success standard for this site corresponds to the Tipple Reference Area total <br />cover value which averaged 33.93 percent total plant cover. Examination of Table 13, Tipple <br />Reclamation - 2010 Plant Cover, reveals that the "total plant cover" on this reclaimed site <br />averaged 39.67 percent. Since the actual "total plant cover" on this reclaimed site (39.67 %) <br />11 <br />
