The total area of the Drainage Channel vegetation type as shown on Map 2.04.10 -1, Permit Area <br />Vegetation Map, is 0.07 acres and this type accounts for 0.22 percent of the proposed mine <br />permit area. <br />REFERENCE AREA VEGETATION SAMPLING <br />IRRIGATED PASTURE REFERENCE AREA <br />The Irrigated Pasture Reference Area sampled in connection with the proposed NHN Mine area <br />is the currently approved reference area for the Irrigated Pasture vegetation type for the existing <br />NH2 Mine Permit Area and is located immediately to the southeast of the New Horizon Mine <br />office. This site was sampled in expectation that the existing vegetation characteristics of this <br />site would be similar to those associated with the Irrigated Pasture predisturbance areas <br />associated with the proposed NHN Mine permit area. <br />Plant Cover. The results obtained from the sampling of the 15 plant cover transects on the <br />Irrigated Pasture Reference Area are presented in Appendix Table 2.04.10 -21, Irrigated Pasture <br />Reference Area- Plant Cover. Total plant cover on this site averaged 76.60 percent and litter <br />averaged 17.33 percent (Appendix Table 2.04.10 -21, Irrigated Pasture Reference Area - Plant <br />Cover). <br />Five plant life forms were encountered in the cover sampling of this site. Native perennial <br />grasses and grasslikes were the dominant plant life form encountered on this site, contributing <br />61.80 percent of the total plant cover and 80.69 percent of the total relative cover found on this <br />site. Perennial forbs were the second most dominant plant life form, contributing 7.47 percent of <br />the total plant cover and 9.74 percent of the total relative cover found on this site. Noxious <br />Weeds contributed 5.07 percent of the total plant cover and 6.61 percent of the total relative <br />cover found on this site. Annuals and biennials contributed 2.27 percent of the total plant cover <br />and 2.96 percent of the total relative cover found on this area. Only one woody plant the tree, <br />Russian Olive, a state listed noxious weed was found growing on this site. <br />Tall Fescue, a planted introduced pasture grass was the most dominant plant species <br />encountered, contributing 25.33 percent of the total relative plant cover found on this site. The <br />other dominant plants encountered were: Kentucky Bluegrass, Baltic Rush, Meadow Fescue and <br />Spreading Bentgrass contributed 14.97, 14.19, 10.62 and 6.88 percent, respectively, of the total <br />relative cover on this area. <br />The locations of the 15 cover transects sampled in the Irrigated Pasture Reference Area are <br />shown on Map 2.04.10 -3 - Irrigated Pasture Reference Vegetation Area.
