In general, these soils are difficult to revegetate. The Razor soil in particular often requires pitting in order to recover very well. These areas • support little wildlife, mainly quail, rabbits, and occasionally pronghorn. When revegetating the Schamber soil, it is useful if the water holding capacity can be increased by removing some of the coarse material and replacing the remaining material as a topsoil. STONEHAM SANDY LOAM: This soil (Figure 3) formed from medium textured, calcareous sediment on upland locations. This soil, although of small quantity on this site, according to the S.C.S. soil survey report, is a much better soil than the more common Schamber soil. Plants root deeply and the available water capacity is high. The native vegetation is mainly blue grams with the addition of various wheatgrasses, needleandthread, and other less abundant species. This soil is much better suited to wildlife than the more common (on this site) Schamber soil. It revegetates rather easily, but may require much fertilizer to produce • rich growths. Wind erosion can be a problem with unprotected soils. KIM LOAM: This soil (Figure 9) is a rich, deep, well drained soil with a high available water capacity. The native vegetation is similar to the Stoneham soil as well as the typical use of the soil which is for rangeland. One distinctive feature of this soil when subjected to overgrazing is the development of incredibly thick stands of prickly pear cactus, however, dense stands of this species are not necessarily an indicator of the soil type. On this site, the soil, according to the S.C.S. soil survey, occurs only in areas below the elevation of the gravel deposit and therefore would only be affected by various other activities such as roads. MAN2ANOLA CLAY LOAM: Like the Kim loam, this soil (Figure 5) is found on areas below the level of the gravel and therefore will only be affected by • page 3 of 7 Exhibit I
