EXHIBIT J <br /> (B) Relationship Of Present Vegetation Types To Soil Types <br /> Table J.(B).1 presents the current vegetation types and their correlation with specific soil types across the West Side Placer <br /> project area. This table illustrates the influence of soil composition on plant distribution and the ecological characteristics <br /> of each soil unit. For example,Eghelm loamy fine sand (0-3%slopes)primarily supports basin big sagebrush(Artemisia <br /> tridentata ssp. tridentata) and Great Basin wildrye (Leymus cinereus),while Fonce sandy loam(1-8%slopes)provides a <br /> foundation for Wyoming big sagebrush(Artemisia tridentata ssp. wyomingensis) and prairie sandreed(Elymus lanceolatus <br /> ssp. lanceolatus). <br /> Additionally,Grimm-Ustic Torriorthents soils(15-45%slopes) and Ruedloff sandy loam(1-8%slopes) contribute to the <br /> diversity of vegetation with a mix of gravelly green river and Great Divide Basin species,further detailed in 6.4.10 EXHIIT <br /> J-Range Production,which illustrates the spatial distribution of these soils.Notable shrubs and grasses in these areas <br /> include rubber rabbitbrush(Chrysothamnus viscidiflorus) and western wheatgrass (Pascopyrum smithii),all of which con- <br /> tribute to the resilience and biodiversity of the site's sagebrush steppe ecosystem. <br /> For a comprehensive view of these soil types and their ecological relevance,see Map 6.4.3 EXHIBIT C- Soils ,which pro- <br /> vides additional details on soil units and their distribution across the project area. <br /> TABLE J.(B).1 <br /> DominantMap Unit Map Unit Name Component Name(Percent) Ecological Site <br /> 62 Eghelm loamy fine sand, Eghelm(90%) R034BY009UT—Loamy Shrub 40.5 5.0% <br /> 0 to 3 percent slopes Natrargids(5%) Bottom(Basin Big Sagebrush) (1)Artemisia tridentata ssp. <br /> Youngston(5%) tridentata <br /> Herbaceous <br /> (1)Leymus cinereus <br /> 75 Fonce sandy loam,1 to Fonce(90%) R034AY424CO—Loamy Shrub 102.0 12.6% <br /> 8 percent slopes Soils with sandy loam upper subsoils(5%) 7-10 PZ (1)Artemisia tridentata ssp. <br /> Soils with less than 15 percent calcium carbonate(3%) wyomingensis <br /> Soils with very gravelly upper subsoils(2%) <br /> Herbaceous <br /> (1)Elymus lanceolatus ssp. <br /> lanceolatus <br /> (2)Achnatherum hymenoides <br /> 92 Grimm-Ustic Grimm(50%) R034AY112WY—Gravelly 76.4 9.5% <br /> Torriorthents,shallow Ustic Torriorthents,shallow(40%) Green River and Great Divide <br /> complex,15 to 45 Moderately deep soils(10%) Basins(Gr) <br /> percent slopes <br /> 154 Quealman sand,0 to 3 Quealman(90%) R034BY012UT—Sandy Herbaceous 15.7 1.9% <br /> percent slopes Medium textured soils(5%) Bottom(Fourwing salbush) Not specified <br /> Soils with loamy sand and sand substratums(5%) Not specified <br /> (1)Achnatherum hymenoides <br /> (2)Hilariajamesii <br /> 168 Ruedloff sandy loam,1 Ruedloff(85%) R034AY150WY—Sandy 304.1 37.7% <br /> to 8 percent slopes Gravelly surfaced soils on sloping to moderately steep break Green River and Great Divide <br /> (5%) Basins(Sy) <br /> Kandaly(5%) <br /> Tresano(5%) <br /> 74 <br /> HARDROCK/METAL MINING REGULAR(112)APPLICATION Au Pt Industries LLC I PO Box 1424-Edwards,Colorado 81632 1970 306 1 784 <br />
