Plant Cover. Total plant cover on this site averaged 92.13 percent and litter averaged 6.74 <br />percent (Appendix Table 2.04.10 -15, Intensively Managed Irrigated Pasture - Plant Cover.) <br />�1,Perennial grasses dominated the plant cover on this site, contributing 56.33 percent of the total <br />I e 1 ,t- cover or 61.36 percent of the total relative cover on this site. Perennial forbs contributed 34.33 <br />6 percent of the total cover and contributed 37.27 percent of the total relative cover on this site. <br />a <br />Z r Noxious weeds contributed 1.27 percent or 1.37 percent of the total relative cover on this site. <br />A � s s 6 ' No annuals or biennials were encountered in the plant cover sampling on this site. <br />r G k„ Tall Fescue, an introduced planted pasture grass, was the dominant plant species growing on this <br />,yo- ( 1 , ' site, contributing 39.29 percent of the total relative cover on this site. Alfalfa, Orchard Grass, <br />G � �? Alsike Clover, and Kentucky Bluegrass were the other dominant species on this site, contributing <br />\�` r s 21.27, 10.34, 9.48 and 6.95 percent, respectively, of the total relative cover on this area. <br />G• 1 <br />The locations of the 15 cover transects sampled on this site are shown on Map 2.04.10 -1, - <br />Permit Area Vegetation Map. The sample adequacy calculations in Appendix Table 2.04.10 -2, <br />New Horizon North Mine Area - Sample Adequacy Calculations, document that the number of <br />samples required to describe the parameter of total plant cover on this site at the 90 percent <br />confidence interval was 0.3 transects. <br />Production. The results obtained from the 30 production transects sampled on this site are <br />presented in Appendix Table 2.04.10 -16, Intensively Managed Irrigated Pasture - Production. <br />The average total production on this site was determined to equal 179.21 g/1 /4m or 6,387.0 <br />pounds of air -dry forage per acre. Perennial grasses contributed an average of 102.33 g/1 /4m or <br />57.10 percent of the total herbaceous forage production. Perennial forbs, contributed an average <br />of 76.88 g/1/4m or 42.90 percent of the total herbaceous production. <br />Appendix Table 2.04.10 -2, Sample Adequacy Calculations, documents that forage production on <br />this site at the 90 percent confidence interval was determined to equal 4.1 transects. The <br />locations of the 30 production transects are shown on Map 2.04.10 -1, Permit Area Vegetation <br />Map. <br />Shrub Density. As documented in Appendix Table 2.04.10 -17, Intensively Managed Irrigated <br />Pasture - Shrub Density, there were no shrubs or woody plants encountered in the sampling of <br />the fifteen cover transects. The average shrub density on this site is zero and as shown in <br />Appendix Table 2.04.10 -2, Vegetation Sample Adequacy Calculations, sample adequacy at the <br />90 percent confidence interval was achieved at zero transects. <br />WETLAND <br />This vegetation type is primarily located in the bottoms of the drainages which flow across this <br />site, such as Chiles Draw, located on the northwestern portion of the site, Meehan Draw which <br />flows across the north - central portion of the property and on other areas that receive irrigation <br />Section 2.04.10 <br />Page 17 November 2011 <br />
