78.06 percent of the total herbaceous forage and perennial forbs, contributed an average of 0.61 <br />g/1 /4m' or 29.94 percent of the forage produced on this site. No annuals or noxious weeds were <br />encountered during the production plot sampling. <br />Table 26 of the Kerr Permit states that total herbaceous production in 1980 on this site averaged <br />7.18 g/1 /4m or 255.7 pounds of air -dry forage per acre. In 1996, RMR reported that the total <br />herbaceous production averaged 3.64 g/1 /4m or 129.7 pounds of air -dry forage per acre. In <br />1999, ESCO reported that the total herbaceous forage production averaged 10.6 g/1 /4m or 377.8 <br />pounds of air -dry forage per acre. In 2005, HvIE reported that total herbaceous forage production <br />averaged 6.61 g/1 /4m or 235.6 pounds of air -dry forage per acre. When sampled in 2009, HVIE <br />reported that total herbaceous forage production averaged 2.78 g/1 /4m' or 99.1 pounds of air -dry <br />forage per acre. <br />The locations of the 30 production transects sampled on this area are shown on Map 1, Alkali <br />Sagebrush Reference Area - 2010 Vegetation Transect Location Map. Examination of Table 2, <br />Marr Mine - 2010 Statistical Summary and Sample Adequacy Calculations, reveals that sample <br />adequacy at the 90 percent confidence interval was equal to 10.3 transects. <br />Species Diversity. The forage quality index calculations for this site are found in Table 5, <br />Alkali Sagebrush Reference Area - 2010 Forage Quality Index Calculations. An exact copy of <br />this table was submitted by KCC to the CDRMS in connection with TR -25. As are documented <br />in Table 5, Alkali Sagebrush Reference Area - 2010 Forage Quality Index Calculations, the <br />forage quality index value for the Alkali Sagebrush Reference Area at the Marr Mine as sampled <br />in 2009 is 199.38. <br />1999 RECLAMATION <br />Plant Cover. The results obtained from the sampling of the 15 plant cover transects on this <br />reclaimed site are presented in Table 6, 1999 Reclamation - 2010 Plant Cover. Total plant cover <br />on this site averaged 42.80 percent and litter cover averaged 30.00 percent (Table 6, 1999 <br />Reclamation - 2010 Plant Cover). <br />Seeded cool season grasses dominated the plant cover on this site, contributing 33.27 percent of <br />the total cover or 77.73 percent of the total relative cover on this reclaimed site. Native shrubs <br />were the second most common plant life for, contributing a total of 4.20 percent of the total <br />cover and 9.81 percent of the total relative cover on this site. Perennial forbs contributed a total <br />of 4.20 percent of the total plant cover or 9.81 percent of the total relative cover on this site. <br />Annuals - Biennials and Noxious Weeds contributed a total of 1.14 percent of the total cover or <br />2.65 percent of the total relative cover on this site. <br />Russian Wildrye was the dominant species followed by Great Basin Wildrye and Western <br />Wheatgrass which contributed 36.13, 21.03 and 15.73 percent, respectively, of the total relative <br />cover on this area. The most dominant shrub was Wyoming Big Sagebrush which contributed <br />8.26 percent of the total relative cover on this reclaimed site. The most dominant forb species <br />growing on this site was Rocky Mountain Penstemon which contributed 7.00 percent of the total <br />
