Substation B totaled 260 pounds per acre, with the perennials contributing 216 pounds to forage <br />production (Table 5b). Woody plant density averaged 1,059 shrubs per acre comprised mostly of <br />shadscale and greasewood with lesser amounts of fourwing saltbush, big sagebrush, and prickly pear <br />cactus scattered throughout the unit (Table 6b). <br />This unit passes all of the proposed revegetation success criteria except the total herbaceous <br />production which fell well below the standard of 558 pounds per acre due to lack of cheatgrass (Table 1). <br />Qualitative analysis indicates that this revegetation is in very good condition overall. This unit exhibits <br />good shrub establishment and diversity of forbs, shrubs, and perennial grasses. <br />3.18 Greasewood Reference Area <br />The Greasewood Reference Area was established as a new comparison area in 1999 and is located <br />approximately 1,500 feet northwest of the Cameo Refuse Disposal Area No. 1 along the east-facing <br />colluvial toe slope adjacent to the BLM Bookcliffs access road and an ephemeral drainage. Ground cover <br />in this area consisted of 54.3% live vegetation, 2.6% rock, 31.2% litter, and bare soil exposure of 12.0% <br />(Table 3a). Perennial cover across the unit averaged 16.3% (down from 19.4% in 2008) with annual and <br />biennial cover averaging 38.0% (down from 42.3% in 2008). The dominant taxa were cheatgrass, <br />greasewood, galleta, and annual wheatgrass with 35.3%, 9.0%, 2.9%, and 2.2% average cover, <br />respectively. Current annual production on the Greasewood Reference Area totaled 530 pounds per acre, <br />with the perennials contributing 132 pounds to forage production (Table 5a). <br />3.19 Shadscale Reference Area <br />The Shadscale Reference Area is located near the Roadside South Portal on the west-facing slope <br />(see Map 1). Ground cover in this area consisted of 50.8% live vegetation, 23.3% rock, 14.1% litter, and <br />bare ground exposure of 12.0% (Table 3b). Perennial cover across the unit averaged 7.1% (down from <br />8.3% in 2008) with annual and biennial cover averaging 43.2% (up from 36.4% in 2008). The dominant <br />taxa were cheatgrass, shadscale, and galleta with 41.4%, 2.6%, and 1.8% average cover, respectively. <br />The noxious weeds, whitetop and bindweed, were also present in the Shadscale Reference Area <br />contributing 0.5% ground cover. Current annual production on the Shadscale Reference Area totaled 621 <br />pounds per acre, with the perennials contributing 94 pounds to forage production (Table 5b). <br />CEDAR CREEK ASSOCIATES, Inc.
