REVEGETATION
The goal of the revegetation efforts is to reclaim the affected areas in such a way as to establish a
diverse, effective and long lasting vegetative cover, compatible and consistent with the native cover.
This vegetation should be consistent with the natural surroundings and be capable of self- regeneration
without continued dependence on irrigation, soil amendments or fertilizer.
Seeding
A standard reclamation grass seed mix approved by the U.S. Department of Agriculture, Natural
Resource Conservation Service, for this area will be used for reclaimed areas of the New Access Road.
The seed mix recommended is easily obtainable from a reputable local seed supply company such as
Western Native Seed.
Seed will be broadcast by machine, hand or hydro seed method on to the prepared disturbed surface.
Rate of broadcast for seed will be 10.4 PLS pounds per acre (see table below for details). Ideally, trees
and shrubs should be planted first to avoid disruption of the seed during these plantings. If a broadcast
method is used to place the seed mix, the surface should be lightly raked after seed broadcast to
incorporate the seed into the top 1/2 inch of soil.
* PLS = pure live seed
** Rate is doubled from NRCS rates per recommendation to account for broadcast method.
SCHEDULE
It is anticipated that the New Access Road will be utilized throughout the mining process. Therefore,
reclamation of the road will not occur until mining activities are complete. Timing of the reclamation
efforts for the New Access Road should take into account the time necessary for plant and seed
establishment. Grading operations to reclaim the New Access Road should not start if there is not ample
time to allow the new vegetation that is part of this Reclamation Plan to begin growing and, in the case
of the seed mix, allow for a proper stand to occur before snow is anticipated.
Typically, the best time to plant is in the late spring (after the spring thaw) or in early fall (late August to
early October). Plantings of shrubs and trees will take between four and six weeks to establish, while the
seed mix will take between two and three months to grow to a good stand. Because it will be difficult to
