<br />may he needed to insure sun•ival. Trees that are be
<br />suited and have good sun•ieal are Rocky Mountain j~
<br />viper, eastern redcedar, ponderosa pine, and Siberian elr
<br />Shrub; that are best suited are skunkbush sumac ar
<br />lilac.
<br />These soils are poorly suited to wildlife habitat. Tht
<br />are typically used as habitat for rangeland wildlife, sw
<br />xs scaled quail and antelope. Livestock grazing mutt
<br />cen• carefully managed if wildlife is to satisfy most of
<br />habitat requirements.
<br />The main limitation for construction on the Schamb
<br />soil is steep slopes. because of rapid permeability, the
<br />is a hazard of pollution if this soil is used for septic to
<br />absorption fields. The high content of coarse fragmen
<br />may cause problems with excavations, mainly because c~t{{
<br />banks cave in. Special designs for buildings and road; arb
<br />necesexr}' to offset the limitation o[ slope. The Razor soil'
<br />i. limited by depth to shale, slow permeability, limited
<br />abilitt• to support a load, shrink-swell potential, and slope.
<br />Both soils are limited by frost-action potential. Special
<br />designs for buildings and roads are needed to overcome
<br />thr<r limitations. Capability subclass VIIe.
<br />86-Stoneham sandy loam, 3 to 8 percent slopes. This
<br />deep, well drained soil formed in medium textured, cal-
<br />cazeous sediment on uplands. Elevation ranges from 5,100
<br />to 6,500 feet. The average annual precipitation is about 14
<br />inches, the average annual air temperature is about ~9
<br />degrees F, and the average frost-free period is about I-15
<br />da}•s.
<br />Typically, the surface layer is pale brown sandy loam
<br />about 4 inches thick The subsoil is pale brown sandy clay
<br />loam about 7 inches thick The substratum is very pale
<br />brown loam to a depth of 60 inches. The lower part of the
<br />.ubsoil and the substratum have visible soft masses of
<br />lime.
<br />[nclutled with this soil N mapping are small area_a of
<br />Fort Collins loam, 0 to 3 percent slopes; Keith silt loam, 0
<br />to 3 percent slopes; and Wiley silt loam, 1 to 3 percent
<br />slopes.
<br />Permeability of this Stoneham soil is moderate. Effec-
<br />tive rooting depth is 60 inches or more. Available water
<br />capacity is high. Surface runoff is medium, and the hazard
<br />of erosion is moderate.
<br />Most areas of this soil are used as rangeland, but a few
<br />small areas are used for sorghum. This soil is also used
<br />for wildlife habitat.
<br />This soil is suited to the production of native vegetation
<br />suitable for grazing. The rangeland vegetation is mainly
<br />blue grams, which has a typical bunchgrass growth form
<br />and makes up one-third to one-half of the cover. Other
<br />species are sand dropseed, needleandthread, side-0ats
<br />grams, and buckwheat. Western wheatgrass, little
<br />bluestem, and junegrass are also present where this soil
<br />occurs in the northern part of the survey area
<br />Seeding is a good practice if the range has deteriorated.
<br />Dative grasses should be used. If the range is severely
<br />eroded and blowouts have developed, fertilizing the new
<br />seeding is a good practice.
<br />Brush control and grazing management help to improve
<br />the depleted range. Grazing should be managed so that
<br />enough forage is left standing to protect the soil from
<br />blowing, to increase the infiltration of water, and to catch
<br />and hold snow.
<br />R'indbreaks and environmental plantings are generally
<br />well suited to this soil. Summer fallow a year prior to
<br />planting and continued cultivation for weed control are
<br />needed to insure establishment and survival of plantings.
<br />Trees that are best suited and have good survival are
<br />Rocky Mountain juniper, eastern redcedar, ponderosa
<br />pine, Siberian elm, Russian-olive, and hackberry. Shrubs
<br />that are best suited are skunkbush sumac, lilac, Siberian
<br />peashrub, and American plum.
<br />This soil is suited to wildlife habitat. It is best suited to
<br />habitat for openland and rangeland wildlife. In cropland
<br />areas, habitat favorable for ring-necked pheasant, mourn-
<br />ing dote, and many nongame species can be developed by
<br />establishing areas for nesting and escape cover. For
<br />pheasant, undisturbed nesting cover is vital and should be
<br />provided for in plans for habitat development. Rangeland
<br />wildlife, such as pronghorn antelope, can be encouraged
<br />by developing livestock watering facilities, properly
<br />managing livestock grazing, and reseeding range where
<br />needed.
<br />This soil is well suited to urban development. The main
<br />limitation for [roads and streets is potential frost-heave
<br />damage. Access roads moat be designed to minimize this
<br />limitation. Capability subclass Vie.
