The mix is to be seeded at 15 lbs./acre drill seeding. If a seed drill cannot be used, <br /> then the mix should be seeded at 25 lbs. per acre broadcast seeding or 35 lbs./acre hydroseeding. The <br /> seed should be planted no more than '/4 inch deep. A seed drill with different seed boxes especially one <br /> for fluffy seed is recommended so that the Blue Grama is properly planted. <br /> Irrigation: Irrigation is not necessary for establishment; however, it does shorten the <br /> establishment period, and may be needed if plantings fail. The grasses can be established within a <br /> growing season with proper irrigation. Without irrigation establishment should take 3 years with normal <br /> or above normal precipitation. Without irrigation and no drought, the grass cover should be close to <br /> baseline coverage in 5 years. <br /> Weed control: The reclaimed area shall be maintained in compliance with the Chaffee <br /> County Noxious Weed Management Plan and Colorado Noxious Weed Act. Annual weeds, Kochia <br /> (Bassia scoparia),Russian Thistle(Salsola spp)Tumblemustard(Sisymbrium altissimum) and Cheatgrass <br /> (Bromus tectorum) should be mowed right before seed set to reduce spread or controlled with herbicides <br /> early in the growing season. Kochia and cheatgrass should be controlled to prevent takeover of the site. <br /> Weed growth is to be expected during the first year and should be monitored. There will be native weeds <br /> that do not present long term problems and should be allowed to grow and replenish their seed banks. All <br /> noxious weeds as well as the above annual weeds should be controlled through mowing and/or herbicides <br /> and affected areas replanted afterwards. Weeds will always exist on site since wind deposited seed cannot <br /> be prevented, however, weed cover should not exceed 15% of total plant cover after the establishment <br /> period. <br /> Milestones: Vegetative cover should be within 5-10%of the baseline cover by year 5. If this <br /> goal has not been met, then the site should be overseeded with the Permanent Seed Mix. Vegetative <br /> cover in years 1-4 will depend on precipitation. Monitoring the vegetation should occur at least once a <br /> growing season so that problems can be addressed in a timely manner. <br /> Prepared by: <br /> Alex Tonnesen <br /> Western Native Seed <br /> PO Box 188 <br /> Coaldale CO 81222 <br /> ACA Products, Inc•702 Gregg Drive; PO Box 1887• Buena Vista,CO 81211 <br /> Phone 719-395-3790• Fax 719-395-3794 <br />
