from pasture plantings of nonirrigated grasses in spring, late in summer, and
in fall to protect the soil from erosion and to provide grazing for livestock.
Good pasture management must be practiced to maintain the grasses.
Crested wheatgrass, pubescent wheatgrass, and smooth brome are adapted
species.
The potential plant community on this soil consists of wheatgrasses,
bluegrasses, and needlegrasses. As range condition deteriorates,
wheatgrasses and needlegrasses decrease, (orbs and woody shrubs
increase, and undesirable weeds and annual plants invade and become
more abundant.
This soil is used for winter range by mule deer and elk. Some important
plant species which can be managed for optimum production are bitterbrush,
mountainmahogany, Gambel oak, serviceberry, and elk sedge.
Berry-producing shrubs are an important habitat element of black bear. This
• soil provides habitat for Merriam turkey, blue grouse, and band-tailed pigeon.
In favorable years mature Gambel oaks produce acorns, which are used by
Merriam turkey.
A soils survey was performed on July 18, 2003 for the area to be disturbed
by the new gob pile. The soils report is presented in Volume III, Tab 7. The
survey area is within the Torriorthents-Haplargids complex, very stony.
Haplargids are deep and well drained. These soils are highly variable, and
profile development is weak to moderate. In some areas a thin dark colored
surface layer is forming. The surface layer most commonly is loam or sandy
loam and is very stony. The subsoil is loam, clay loam, or light clay and has
cobbles and stones. Content of rock fragments exceeds 35%.
(1)(c) A soils map or enlarged aerial photo of the same scale as the permit area map shall
be provided.
A Soils Map (Map 4) is presented in Volume II Maps.
