• transplants used in revegetation efforts will be taken from this listing of
plant species. The list of plant species contained in Table 9.4-1 may be
added to as additional species adapted to our region become available
commercially. Detailed descriptions of the attributes of the plant species
selected for use, based on the P.I.N. information, are contained in
Appendix 4.9-A. For those species selected which are introduced, Appendix
4.9-A contains information addressing requirements concerning their use.
SEED MIXTURES
This subdivision contains descriptions of the permanent and temporary
seed mixtures to be used in the revegetation program, including procedures
to be used to procure regulatory approval when changes are made in their
composition. Each seed mixture is described separately below. Species
selected for use in the seed mixtures have been chosen for their ability to
accomplish specific revegetation goals based on the type of revegetation
that needs to be established.
Permanent Seed Mixtures-Overview
• Permanent revegetation seed mixtures have been formulated to address
both short-term and long-term goals. In the short-term, permanent
revegetation seed mixtures need to provide for the rapid establishment of
vegetation which is capable of stabilizing replaced soil materials. Long-
term goals include the establishment of a stable, self-sustaining rangeland
or riparian plant community capable of supplying food and cover for
domestic livestock, and providing wildlife habitat and browse. It is
anticipated that permanent revegetation efforts will increase available,
palatable forage on the reclaimed rangeland (A.U.M. ratings should improve
from 12 acres to five or six acres based on past monitoring at the mine
site). Since wildlife habitat is a secondary land use, permanent
revegetation seed mixtures are also formulated to supply forage, meet
nutritional needs, provide cover and create beneficial edge effects for
wildlife.
Rhizomatous grasses are the plants that are most efficiently adapted
for rapid, effective soil stabilization. Currently, there are commercially
available a number of native, rhizomatous grasses that occur in Routt
County within the elevational ranges of the Edna Mine. The permanent
rangeland seed mixture relies heavily on these grasses, in combination with
• perennial, native clump grasses, to achieve topsoil stabilization. Various
forbs are included in the seed mixtures in an effort to diversify the
