• This soil is used for winter range by mule deer. Big sagebrush, <br />mountainmahogany, and bitterbrush are important browse species which can <br />be managed for optimum production. <br />If this soil is used for urban development, the main limitations are <br />depth to bedrock and corrosivity. If it is used for septic tank <br />absorption fields, permeability is also a limitation. The limitations <br />can be overcome by the use of proper design and construction methods. <br />This soil is in capability subclasses IVe, irrigated, and VIe, <br />nonirrigated. <br />Torriorthents-Haplargids complex, very stony. <br />The soils in this complex are nearly level to strongly sloping and are <br />on toe slopes and small fans and in narrow, winding valleys. They are <br />forming in an accumulation of locally transported stony materials <br />• derived from a variety of rock. Slopes are 0 to 12 percent. <br />Torriorthents make up about 55 percent of this complex and are lower on <br />the toe slopes than Haplargids and are in the bottom of small <br />drainageways. Haplargids make up about 40 percent. They are more <br />sloping than Torriorthents and are on toe slopes and fans. <br />Included with these soils in mapping are areas of Fluvents, flooded, <br />that 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 <br />is very stony. The underlying layers are sandy loam, loam, or clay loam <br />and have cobbles, stones, and boulders. Content of rock fragments in <br />the profile exceeds 35 percent. <br />• Permeability of the Torriorthents is rapid to moderately slow. <br />Avoidable water capacity is moderate to low. Roots penetrate to a depth <br />
