percent (204.3 pounds per acre) of the total production is attributable to annuals (mostly <br />grasses). <br />Perusal of Table E5-20 indicates that the estimated woody plant density in this area was <br />1,280 woody plants per acre with shrubs accounting for 833 of the plants and trees accounting <br />for the remaining 447 plants per acre. Mountain Snowberry was the dominant woody species <br />with 696 plants per acre followed by Utah Juniper with 257 plants per acre. <br />3.1.3 Old Juniper Woodland Reference Area <br />The old Juniper Woodland reference area is located along the southern border of the permit <br />boundary (see Map E5-1) within the newly proposed disturbance footprint. Review of Table E5- <br />12 and Chart E5-1 indicates that the average vegetation cover of the old Juniper Woodland <br />reference area was 44.9%. Bare ground exposure and rock provided an average of 6.65% and <br />0.55% of the ground cover, respectively, while litter covered a significant 47.9%. The dominant <br />plant species were cheatgrass, mountain snowberry, and mountain pepperweed (Lepidium <br />montanum) with 22.75%, 7.85% and 3.7% of the ground cover, respectively. Perennial plants <br />contributed 41% of the composition (18.2% average cover) while annual species contributed <br />55% of the composition. Remaining composition was comprised of noxious weeds. Perusal of <br />Table E5-8 indicates that a total of 4 perennial species contributed at least 3% relative cover or <br />composition. Three of these species were forbs and one was a shrub. <br />Review of Table E5-17 and Chart E5-3 indicates that the average herbaceous production of <br />this area in 2006 was 180.3 pounds per acre, oven-dry weight. Twenty-four percent (43.3 <br />pounds per acre) of the total herbaceous production is attributable to perennials, with grasses <br />contributing 0.2 Ibs/acre, forbs 14.6 Ibs/acre, and sub-shrubs providing 28.5 Ibs/acre. Seventy- <br />six percent (137 pounds per acre) of the total production is attributable to annuals (mostly <br />grasses). <br />Perusal of Table E5-21 indicates that the estimated woody plant density in this area was <br />2,486 woody plants per acre with shrubs accounting for 1713 of the plants and trees accounting <br />for the remaining 773 plants per acre. Mountain Snowberry was the dominant woody species <br />with 1,582 plants per acre followed by Utah Juniper with 520 plants per acre. <br />3.1.4 Study Area -Reference Area Comparability <br />Review of Table E5-1 indicates that only total production for the Juniper Woodland baseline <br />study area is statistically comparable to the values obtained from the New Juniper Woodland <br />reference area. Total cover for this same comparison statistically °failed". Similarly, both total <br />,~ <br />~~~~ (C~~~ A~~®cn~~s, INC. 9 Exhibit 5 -Vegetation Resources <br />
