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 />Western Wheatgrass <br />Sideoats Grama <br />Mountain Brome <br />Prairie Sandreed <br />Switchgrass <br />Alkali Sacaton <br />Needle and Thread <br />Northern Sweetvetch <br />Rocky Mountain Penstemon <br />Scarlet Globemallow <br />Prairie Wildrose <br />Agropyron smithii <br />Bouteloua curtipendia <br />Bromus marginatus <br />Calamovilfa longifolia <br />Panicum virgatum <br />Sporobolus airoides <br />Stipa comata <br />Hedysarum boreale <br />Penstemon strictus <br />Sphaeralcea coccinea <br />Rosa Arkansana <br />Arriba <br />Butte <br />Bromar <br />Goshen <br />Pathfinder <br />Timp. <br />Bandera <br />ARS2936 <br />17.0% <br />17.5% <br />17.0 % <br />1.0% <br />7.0% <br />1.0% <br />13.0% <br />10.0% <br />5.0% <br />3.0% <br />8.5% <br />2.55 <br />2.63 <br />2.55 <br />.15 <br />1.05 <br />.15 <br />1.95 <br />1.50 <br />.75 <br />.45 <br />1.28 <br />Total lbs /ac <br />100% <br />15.01 <br />1 Pure Live Seed pounds per acre; rates shown are for drill seeding; double rates for broadcast <br />seeding. <br />Iverson Mine <br />DRMS 112 Reclamation Permit Application <br />Page E3 of E4 <br />
