• Typically the surface layer of the Beenom soil is gray-
<br />ish brown loam about 4 inches thick. The subsoil is dark
<br />brown clay loam about 5 inches thick. The substratum is
<br />very pale brown channery loam. Sandstone is at a depth
<br />of about 14 inches. _ _
<br />In the Beenom soil, permeability is moderate and avail-
<br />able water capacity is low. Effective rooting depth is
<br />about 14 inches. Surface runoff is rapid. The hazard of
<br />erosion from wind is slight and from water is high.
<br />On the Beenom soil the native vegetation consists
<br />mainly of Gambel oak, serviceberry, big sagebrush, and
<br />snowberry. Whealgrasses, pine needlegrass, and need-
<br />leandthread are common grasses.
<br />The potential plant community on the Beenom soil
<br />consists mainly of bluebunch wheatgrass and other
<br />wheatgrasses, muttongrass, and Junegrass. As range
<br />condition deteriorates, the wheatgrasses, muttongrass,
<br />and Junegrass decrease, forbs and woody shrubs in-
<br />crease, and undesirable weeds and annual plants invade
<br />and become more abundant.
<br />Seeding can be done on the Beenom soil if range is in
<br />poor condition, but sleep slopes and surface stoniness
<br />are limitations. Western wheatgrass and bluebunch
<br />wheatgrass are suitable for seeding. Grasses that meat
<br />the seasonal requirements of livestock should be select-
<br />• ed. Preparing a seedbed and drilling the seed, where
<br />possible, help to obtain the best results. Seeded areas
<br />should be fenced.
<br />The Beenom soil is used for winter range by mule
<br />deer. At the high elevations it is used for winter range by
<br />elk. Some important plant species which can be man-
<br />aged for optimum production are big sagebrush, bitter-
<br />brush, serviceberry, low rabbitbrush, and wild rose.
<br />It the Beenom soil is used for urban development, the
<br />main limitations are slope, depth to bedrock, and shrink-
<br />swell potential. If it is used for septic tank absorption
<br />fields, permeability is also a limitation. The limitations
<br />can be overcome by the use of proper design and con-
<br />struction methods.
<br />The Absarokee soil is well drained and overlies bed-
<br />rock at a depth of 20 to 40 inches. It formed in locally
<br />transported sediment derived from sandstone and inter-
<br />bedded shale.
<br />Typically the surface layer of the Absarokee soil is
<br />dark grayish brown loam about 7 inches thick. The sub-
<br />soil is brown clay about 18 inches thick. The substratum
<br />is light brown channery clay loam. Sandstone is at a
<br />depth of about 30 inches.
<br />In the Absarokee soil, permeability is moderately slow
<br />and available water capacity is tow. Effective rooting
<br />depth is about 30 inches. Surface runoff is rapid. The
<br />• hazard of erosion from wind is slight and from water is
<br />moderate to high.
<br />On the Absarokee soil the five vegetation consists
<br />mainly of Gambel oak, service arty, big sagebrush, and
<br />snowberry. Whealgrasses, re dropseed, needie-
<br />grasses, brome, and needla ~dthread are common
<br />grasses.
<br />Most areas of this associatir are used for grazing by
<br />livestock and wildlife and for rc national purposes.
<br />Because of steepness of slc ~, the Absarokee soil is
<br />unsuited to crops and reseed; I of depleted or burned
<br />areas in native vegetation is nc feasible by conventional
<br />methods. A fair degree of suc :ss can be expected by
<br />broadcasting seed for nonirrig =d plantings of grasses
<br />in spring or fall. Smooth brom pubescent wheatgrass,
<br />and crested wheatgrass are ac >ted species. Good pas-
<br />ture management should be acticed to maintain the
<br />grasses.
<br />The potential plant commur. on the Absarokee soil
<br />consists mainly of Gambel oe mountain brome, nod-
<br />ding brome, slender wheatgr :s, and elk sedge. As
<br />rahge condition deteriorates, ~untain brome, nodding
<br />brome, slender wheatgrass, d elk sedge decrease,
<br />forbs and woody shrubs in =_ase, and undesirable
<br />weeds and annual plants in de and become more
<br />abundant.
<br />Seeding is advisable on the ~sarokee soil it range is
<br />in poor condition. Slender ~eafgrass and western
<br />wheatgrass are suitable Tor se Ping. Grasses that meet
<br />the seasonal requirements of I stock should be select-
<br />ed. Where possible, preparing seedbed and drilling the
<br />seed help to obtain the best re Its.
<br />On some sites, control of coy Feting shrubs is required
<br />to improve range condition. :ded or brushed areas .
<br />should be Tenced.
<br />The Absarokee soil is used ~r winter range by mule
<br />deer and elk. Some important lant species_ which can
<br />be managed for optimum pr auction are bitterbrush,
<br />mountainmahogany, Gambel c :, serviceberry, and elk
<br />sedge. Berry-producing shrubs .re an important habitat
<br />element for black bear. This oil provides habitat for
<br />Merriam turkey, blue grouse, jband-tailed pigeon. In
<br />favorable years mature Gamt oaks produce acorns,
<br />which are used by IJierriam Curl ~.
<br />If the Absarokee soil is usE for urban development,
<br />the main limitations are depth ~ bedrock and slope. li
<br />this soil is used Tor septic tanF bsorption fields, perme-
<br />ability is also a limitation. ThE imitations can be over-
<br />come by the use of proper asign and construction
<br />methods.
<br />This association is in capab y subclass Vlle, nonirri-
<br />gated.
