The Barx soil is classified as afine-loamy, mixed, Mesic Ustollic Haplargid. <br />It is a deep, well drained sandy loam located on mesas and terraces and formed <br />in sandstone derived alluvium. Typically, the Al horizon is brown fine sandy <br />loam 2 inches thick. The A2 horizon is a reddish brown loam 3 inches thick. <br />The upper part of the B horizon is yellowish red or light reddish brown sandy. <br />clay loam 18 inches thick. The lower 15 inches of the B horizon is pinkish <br />white loam. The upper 13 inches of the C horizon is very pale brown loam and <br />the lower part to a depth of 74 inches or more is pink loam. In some areas <br />the surface layer.is loam or sandy clay loam. <br />Permeability of the Barx soil is moderate. Available water capacity is high. <br />Effective rooting depth is 60 inches or more. Runoff is slow and the hazard <br />of water erosion is slight. An average of 13 to 23 inches of suitable topsoil <br />is available for salvage from Barx soil areas. <br />The Progresso loam is classified as a fine, loamy, mixed, Mesic Ustollic <br />Haplargid. These soils are located on old terraces and mesas, and are <br />moderately deep and well drained soil formed in alluvium derived predominantly <br />from sandstone. Typically, the surface layer is reddish brown loam 7 inches <br />thick. The subsoii is reddish brown clay loam 17 inches thick. The <br />substratum is whitish sandy loam 12 inches thick. Hard sandstone is at a <br />depth of 36 inches. In some areas the surface layer is fine sandy loam. <br />Permeability of the Progresso soil is moderate and available water holding <br />capacity is moderate. Effective rooting depth is 20 to 40 inches. Runoff is <br />rapid and the hazard of water erosion is high. An average of between 9 and <br />13 inches of suitable topsoil is available for salvage from Progresso soil <br />areas. <br />The Pinon loamy are classified as loamy, mixed, Mesic lithic Ustollic <br />caiciorthids. These 5011 are located on edges of mesas, benches and <br />escarpments and is a shallow and well drained soil formed in residuum derived <br />from interbedded sandstones and shales. Typically, the surface layer is brown <br />loam about 5 inches thick. The underlying material to a depth of 16 inches is <br />pinkish white loam. Hard sandstone is at a depth of i6 inches. <br />Permeability of Pinon soil is moderate and the available water holding <br />capacity is very low. Effective rooting depth is 10 to 20 inches, runoff is <br />moderate and the hazard of water erosion is high. An average of between 9 and <br />14 inches of suitable topsoil is available for salvage from Pinon soil areas. <br />Paradox fine sandy loam is located on alluvial fans and narrow alluvial valley <br />floors. This deep, well drained soil is formed in alluvium derived dominantly <br />from sandstone. Typically, the surface layer is red fine sandy loam 5 inches <br />thick. The upper 14 inches of the underlying material is red fine sandy <br />loam. The lower part to a depth of 60 inches is red loam. <br />An average of between 23 and 66 inches of suitable topsoil is available for <br />salvage in the Paradox soil areas. <br />Vegetation, Wildlife and Land Use <br />Four vegetation communities are presently found in the proposed permit area: <br />Upland sagebrush, Juniper-Pinon woodland grassland and disturbed grassland. <br />The Native Grassland reference areas will apply to all of the Native Grassland <br />-5- <br />
