The occurrence of specific vegetative communities within a particular area or
region are the direct result of various abiotic factors such as climate, soils,
topography and time. A climatic description of the proposed mine plan area and
the Craig region in general has already been detailed in Section 2.1 of the per-
mit application. Likewise, soils are described in Section 2.6. A comparison of
the 4800 scale soils maps and vegetation maps will demonstrate the general rela-
tionship between soils and vegetation. A detailed description and table of dom-
inant species response to various abiotic influences is presented in Section
2.3.1.3 , Table 2.3-8.
The fourth factor, time, cannot be addressed in this application since no quanti-
tative information is available as to the time sequence for natural succession in
this area.

2.3.1 Species Inventory, Dominance and Habitat Descriptions
A list of plant species identified within the proposed mine plan area is provided
in Table 2.3-1. Dominance and habitat descriptions are based on 1979 and 1980
cover data.
2.3.1.1 Species Inventory
The species inventory
was developed
from plant collections
made
by Ecology

1975). This is
explainable by
the fact that SCS range site descriptions are
of the "Environmental
based
on descriptions
of climax communities. The areas within the proposed mine
plan
area designated
pinyon -juniper
have suffered the effects of fire and exten-
sive
domestic and wildlife grazing
that may have prevented pinyon pine from
establishing.
