The Progresso loam is classified as a fine, loamy, mixed, Mesic Ustollic Hapiargid. These soils are located on old terraces and mesas, and are moderately deep and well drained soil formed in alluvium derived predominantly from sandstone. Typically, the surface sayer is reddish brown loam 7 inches thick. The subsoil is reddish brown clay loam 17 inches thick. The substratum is whitish sandy loam 12 inches thick. Hard sandstone 1s at a depth of 36 inches. In some areas the surface layer is fine sandy loam. Permeabillty of the Progresso soil is moderate and available water holding capacity is moderate. Effective rooting depth is 20 to 40 inches. Runoff is rapid and the hazard of water erosion is high. An average of between 9 and 13 inches of suitable topsoil is available for salvage from Progresso soil areas. The Pinon loams are classified as loamy, mixed, Mesic lithic Ustollic calciorthids. These soil are located on edges of mesas, benches and escarpments and is a shallow and well drained soil formed in residuum derived from interbedded sandstones and shales. Typically, the surface layer 1s brown loam about 5 inches thick. The underlying material to a depth of 16 inches is pinkish white loam. Hard sandstone is at a depth of 16 inches. Permeabillty of Pinon soil is moderate and the available water holding capacity is very low. Effective rooting depth is 10 to ZO inches, runoff 15 moderate and the hazard of water erosion is high. An average of between 9 and 14 inches of suitable topsoil is available for salvage from Pinon soil areas. Paradox fine sandy loam is located on alluvial fans and narrow alluvial valley floors. This deep, well drained soil is formed in alluvium derived dominantly from sandstone. Typically, the surface layer is red fine sandy loam 5 inches thick. The upper 14 inches of the underlying material is red fine sandy loam. The lower part to a depth of 60 inches is red loam. An average of between 23 and 66 inches of suitable topsoil is available for salvage 1n the Paradox soil areas. Vegetation, Wildlife and Land Use Four vegetation communities are presently found in the proposed permit area: Upland sagebrush, Juniper-Pinyon woodland grassland and disturbed grassland. The upland sagebrush community dominates the area by occupying 417 acres or 62 percent of the proposed permit area. The Juniper-pinyon woodland vegetation community occupies 175 acres or Z6 percent of the proposed permit area. Grassland occupies 76 acres or 11 percent of the area while disturbed grassland occupies 9 acres or 1 percent. Total vegetation cover in the sagebrush area averages 18.4 percent; in the Juniper-Pinyon woodland cover averages 1'9.7 percent; in the grassland cover averages 20.4 percent. The upland sagebrush Community is dominated by big sagebrush (Artemesia tridentata>, needle-and-thread grass (Stipa comata) and blue grams (Bouteloua gracilis). Other grasses include sand dropseed (Sporobolus cryptandrus>, squirrel-tall (Elymus elvmoides>, Indian ricegrass (Oryzoosis hymenoides) and galleta (Hilaria amesii>. -9-
