<br /> <br />• The proposed seed mix and application rates in pounds of pure live seed per acre are <br />described on the following pages. <br />• Weed control practices will be implemented as required. <br />The above procedures may be modified as conditions dictate. If a significant invasion of noxious <br />weeds occurs, the area will be mowed periodically for control. Weeds will be mowed before they <br />go to seed during the first growing season. Mechanical control will be used as a first priority. <br />Chemical methods will be used only if no other alternative produces acceptable results. <br />Marsh and aquatic plants are expected to establish themselves along the shoreline of the post- <br />mining pond. The species of plants anticipated to establish themselves naturally along the pond <br />shoreline include cattails, willows, cottonwoods, and bulrushes. The existing riparian areas along <br />the Cache la Poudre River would function as a seed bank for the pond area. These plants should <br />minimize shore erosion potential. The following are the proposed seed mixtures to be used on site <br />where appropriate. However, availability may dictate the need for variety substitution. <br />Seed Mix for Upland Areas <br /> <br />Common Name <br />Scientific Name <br />Variety % of <br />Mix PLS` <br />Application <br />Rate lbs/ac <br />Western Wheatgrass Agropyron smithii Arriba 17.0% 1.74 <br />Sideoats Grama Bouteloua curtipendia Butte 17.5% 1.80 <br />Mountain Brome Bromus marginatus Bromar 17.0% 1.74 <br />Prairie Sandreed Calamovilfa longifolia Goshen 1.0% 0.48 <br />Switchgrass Panicum virgatum Pathfinder 7.0% 0.67 <br />Alkali Sacaton Sporobolus airoides 1.0% 0.10 <br />Needle and Thread Stipa comata 13.0% 1.29 <br />Northern Sweetvetch Hedysarum boreale Timp. 10.0% 1.02 <br />Rocky Mountain Penstemon Penstemon strictus Bandera 5.0% 0.46 <br />Scarlet Globemallow Sphaeralcea coccinea ARS2936 3.0% 0.26 <br />Prairie Wildrose Rosa Arkansana 8.5% 0.87 <br />Totallbs/ac 100% 10.43 <br />i Pure Live Seed pounds per acre; rates shown are for drill seeding; double rates for broadcast <br />seeding. <br />Greeley 35'" Avenue Pit (M-1977-036) <br />DRMS 112 Reclamation Permit Amendment Application <br />Page E3 of E4
