- Topsoil stockpile #2 was graded and broadcast seeded with
the following stabilizing seed mix:
Species pls lbs/acre
Winter Rye 20
San Luis Wheatgrass 3
Jose Tall Wheatgrass 3
San Luis and Jose Tall Wheatgrasses were substituted for
Crested Wheatgrass at the suggestion of the Soil
Conservation Service office in San Luis. The San Luis
species was developed in the San Luis Valley and has
successfully been used at several highway reclamation sites
in the area.
- The first lift of waste Rock Area D (16 acres), then first
lift of the East Pit Backfill (10 acres), and the Pink
Gneiss Area-Northwest Corner of the West Pit (6 acre:;) were
graded to a 3H:1V slope, topsoiled, and broadcast seE~ded
with the following seed mix:
Species pls lbs/acre
Winter Rye 20
San Luis Wheatgrass 3
Mountain Brome 3
Jose Tall Wheatgrass 2.5
Western Wheatgrass 2.5
Cicer Milkvetch 1.5
Sheep Fescue 1.5
Indian Ricegrass 2
Small Burnet 2
Mountain Mahogany 0.5
Mountain Muhly 1
4-Wing Saltbrush 1
Yellow Sweet Clover 1
Blue Flax 0.5
Yarrow 0.25
Blue Grama and Winterfat seeds were not available. 4iinter
Rye, San Luis Wheatgrass, Jose Tall Wheatgrass, Sheel>
Fescue, and Small Burnet were added to the grasses seeded to
improve the first year stand for stabilizing the sloFse.
4-wing Saltbrush was substituted for Winterfat for a
browsing plant. Yellow Sweet Clover, Blue Flax, and Yarrow
were added to the seed mix as a range wildflower variety.
- The first lift of Waste Rock Area B (15 acres) had been
graded, topsoiled, and seeded in 1991; however, the :seeding
had limited success. In November 1992, this area wars again
seeded to improve the vegetative cover. The same seed mix
as applied to the East Pit Backfill and Waste Rock D was
used for the overseeding of Waste Rock B.
