• <br />The locations of the 15 shrub density transects sampled on this site are shown on Map 2.04.10 -1, <br />Permit Area Vegetation Map. Examination of the sample adequacy calculations in Appendix <br />Table 2.04.10 -2, New Horizon North Mine Area - Sample Adequacy Calculations, reveals the <br />number of samples required to describe the shrub density on this area at the 90 percent <br />confidence interval was 115.8 transects. Since the DRMS informed WFC that it was not <br />necessary to sample adequacy with respect to shrub density sampling, it can be concluded that <br />this area satisfies the sample adequacy requirements with respect to shrub density. <br />INTENSIVELY MANAGED IRRIGATED PASTURE <br />This vegetation type is only found on the western portions of the Garvey property. It is <br />distinguished from irrigated pasture, in that these areas are intensively irrigated, with the water <br />being changed twice a day and these areas routinely receive supplemental fertilizer, whereas the <br />irrigation water on the irrigated pasture is often not moved for days or weeks at a time and has no <br />history of being fertilizer. This vegetation type is the fifth largest plant community type found <br />within the proposed NHN Mine permit area (Map 2.04.10 -1 - Permit Area Vegetation Map). <br />This vegetation type covers an area approximately 37.11 acres in size and accounts for nearly <br />11.52 percent of the proposed permit area. <br />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 />Perennial grasses dominated the plant cover on this site, contributing 56.33 percent of the total <br />cover or 61.36 percent of the total relative cover on this site. Perennial forbs contributed 34.33 <br />percent of the total cover and contributed 37.27 percent of the total relative cover on this site. <br />Noxious weeds contributed 1.27 percent or 1.37 percent of the total relative cover on this site. <br />No annuals or biennials were encountered in the plant cover sampling on this site. <br />Tall Fescue, an introduced planted pasture grass, was the dominant plant species growing on this <br />site, contributing 39.29 percent of the total relative cover on this site. Alfalfa, Orchard Grass, <br />Alsike Clover, and Kentucky Bluegrass were the other dominant species on this site, contributing <br />21.27, 10.34, 9.48 and 6.95 percent, respectively, of the total relative cover on this area. <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 />• Section 2.04.10 Page 16 April 2011 <br />
