within the community. Serviceberry occurs on the drier, shallow soil habitats, and
oak occurs on the moist, deeper soil sites.
Aspen stands occur on north slopes at the higher elevations as small
communities amid the mountain shrub community type in the high moisture habitats.
They typically occur in depressions at the head of drainages and in snow accumula-
tion sites.
A pinon-juniper (Pinus edulis-Juniperus spp.) community occurs on the
very dry southern slopes at the lowest elevation of the permit azea in localities
where the bedrock is often close to the surface. Soils in such habitats are coazse,
porous, very shallow, and often non-existent.
The mine plan azea historically has been used for grazing livestock. hs
recent yeazs sheep have been grazed during late summer. Some of the wet meadows
• aze mowed and the forage stored for winter livestock usage. Introduced grasses
have been planted in the flatter portion of a few of the drainage bottoms. These
fields aze used to produce hay or aze grazed by livestock.
The proposed resource development would directly affect only three of
the mine plan area plant community types. They include: meadow, big sagebrush
and mountain shrub. Each of these communities was quantitatively sampled for
vegetation cover, shrub density and above ground net productivity. The entire mine
plan azea, however, has been mapped. The following sections provide a discussion of
the results of the quantitative analysis.
Exhibit K-1 illustrates the plant community types on the proposed mine
plan azea and the azea to be affected by the intended development. Table K-1
identifies the acreage of each plant community type in the proposed Mine Plan area
and in the area that would be directly affected.
