In favorable years mature Gambel oaks produce acorns, which are used by <br />Merriam turkey. <br />25 — Cochetopa stony loam, 10 to 40 percent slopes <br />This is a deep, well drained soil. It formed in landslide deposits and alluvium <br />and is on uplands, fans, and side slopes of valleys and mountains. Elevation <br />ranges from 8,000 to 9,800 feet. Average annual precipitation is about 22 <br />inches, average annual air temperature is about 39 degrees F, and the <br />average frost -free season is about 75 days. <br />Permeability is slow, and available water capacity is high. Effective rooting <br />depth is 60 inches or more. Surface runoff is medium to rapid. The hazard <br />of erosion from wind is slight and from water is moderate to high. <br />Included with this soil in mapping are a few small areas of Delson, Fughes, <br />and Curecanti soils. Also included are areas of steep, stony soils and <br />Fluvaquents, flooded. In some areas the surface layer is stony clay loam or <br />is free of stones. In some small areas the soil has a higher content of stones <br />and cobbles. <br />The native vegetation on this soil are in noncommercial forest and are used <br />for limited grazing of livestock and wildlife and for recreational purposes. <br />Because of surface stoniness and slope, this soils is unsuited to crops. <br />Seedbed preparation and drilling of seed for pasture plantings on depleted <br />native range or in cleared areas generally are not practical because of <br />surface stoniness. A limited degree of success can be expected by <br />broadcasting seed late in summer or early in fall. Intermediate wheatgrass, <br />smooth brome, and crested wheatgrass are adapted species. Good pasture <br />management must be practiced to protect the soils from erosion and to <br />provide grazing for livestock. <br />The potential plant community consists mainly of fescues, needlegrasses, <br />and wheatgrasses. As range condition deteriorates, these grasses <br />PR -14 2.04-91- 03/14 <br />
