2.04.9 <br />These soils have limited potential for habitat for blue grouse. <br />Encouragement of pinyon and juniper on suitable sites can lead to <br />establishment of a browse -grass plant community beneficial to livestock and <br />mule deer. Pinyon and juniper trees provide cover that is vital habitat <br />requirement of mule deer and should be considered in management. <br />74 — Torriorthents - Haplargids complex, very stony. <br />The soils in this complex are nearly level to strongly sloping and are on toe <br />slopes and small fans and in narrow winding valleys. They are forming in an <br />accumulation of locally transported stony materials derived from a variety of <br />rock. Slopes are 0 to 12 percent. <br />Included with these soils in mapping are areas of Fluvents, flooded, that <br />make up 5 percent of this map unit. <br />Torriorthents are deep and well drained. They have little or no profile <br />development. The surface layer ranges from sandy loam to clay loam and it <br />very stony. The underlying layers are sandy loam, loam, or clay loam and <br />have cobbles, stones, and boulders. Content of rock fragments in the profile <br />exceeds 35 percent. <br />Permeability of the Torriorthents is rapid to moderately slow. Available water <br />capacity is moderate to low. Roots penetrate to a depth of 60 inches or <br />more. Surface runoff is moderate. The stony surface layer helps to prevent <br />erosion. Some areas are subject to rare flooding. <br />Haplargids are deep and well drained. These soils are highly variable, and <br />profile development is weak to moderate. In some areas a thin, dark colored <br />surface layer is forming. The surface layer most commonly is loam or sandy <br />loam and is very stony. The subsoil is loam, clay loam, or light clay and has <br />cobbles and stones. Content of rock fragments exceeds 35 percent. <br />Permeability of Haplargids is moderate to moderately slow. Available water <br />capacity is moderate to low. Rooting depth is 60 inches or more. Surface <br />PR -14 2.04-108- 03/14 <br />
