t� <br />EXHIBIT 5 <br />quantitative vegetation sampling of the plant cover, perennial herbaceous forage production and <br />shrub density are presented below. <br />Plant Cover. The results obtained from the sampling of the 25 plant cover transects on this <br />area are presented in Table 2.04.10 -3, Greasewood Predisturbance Area - Plant Cover. Total <br />plant cover on this site averaged 18.76 percent and litter cover averaged 18.16 percent. <br />Native perennial fortis were the dominant plant life form encountered on this site, contributing <br />10.16 percent of the total plant cover and 54.16 percent of the total relative cover found on this <br />site. Native shrubs were the second most dominant plant life form, contributing 7.12 percent of <br />the total plant cover and 37.95 percent of the total relative cover. Annuals and biennials <br />contributed 1.24 percent of the total plant cover and 6.61 percent of the total relative cover. <br />Native perennial grasses contributed 0.24 percent of the total plant cover and 1.28 percent of <br />the total relative cover found on this area. <br />Gray Molly, a native perennial forb was the dominant plant species encountered, contributing <br />54.16 percent of the total relative plant cover found on this site. The other dominant plants <br />encountered were: Greasewood, Halogeton, and Peppergrass which contributed: 7.12, 0.76 and <br />0.44 percent, respectively, of the total relative cover on this area. <br />• The locations of the 25 cover sampled in the Greasewood Predisturbance Area are shown on <br />Map 3, Permit Area Vegetation Map. The sample adequacy calculations in Table 2.04.10 -2, <br />Loadout Area - Sample Adequacy Calculations, document that the number of samples required <br />to describe this site with respect to plant cover at the 90 percent confidence interval was 20.6 <br />transects. <br />Production. The results obtained from the sampling of 50 production transects on this area are <br />summarized in Table 2.04.10 -4, Greasewood Predisturbance Area - Production. The average <br />total herbaceous forage production equaled 13.39 g /1/4 m or 477.2 pounds of air -dry forage <br />per acre. Perennial forbs contributed 11.69 g /1/4 m or 87.33 percent of the herbaceous forage. <br />Annual forbs, contributed 1.61 g /1/4 m or 12.02 percent of the herbaceous forage production. <br />Native perennial grasses, consisting entirely of Desert Saltgrass, contributed 0.10 g /1/4 m or <br />0.74 percent of the herbaceous forage production. <br />The locations of the 50 production transects sampled on this site are shown on Map 3, Permit <br />Area Vegetation Map. The sample adequacy calculations in Table 2.04.10 -2, Loadout Area - <br />Sample Adequacy Calculations, document that the number of samples required to describe this <br />site in terms of total herbaceous forage production at the 90 percent confidence interval was <br />93.3 transects. <br />Shrub Density. The shrub density counts obtained from the 15 belt transects sampled in this <br />area are summarized in Table 2.04.10 -5, Greasewood Predisturbance Area - Shrub Density. <br />The average shrub density was determined to equal 17.84 shrubs per one hundred square <br />r� <br />
