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 /> <br />Common Namc Scientific Name /? of <br /> <br />Varier) <br />PLS <br />_ pIdication <br />Rate Obs/ac) <br />Western Wheatgrass Agropyron smithii Arriba 17.0% 2.55 <br />Sideoats Grama Bouteloua curtipendia Butte 17.5% 2.63 <br />Mountain Brome Bromus marginatus Bromar 17.0% 2.55 <br />Prairie Sandreed Calamovilfa longifolia Goshen 1.0% .15 <br />Switchgrass Panicum virgatum Pathfinder 7.0% 1.05 <br />Alkali Sacaton Sporobolus airoides 1.0% .15 <br />Needle and Thread Stipa comata 13.0% 1.95 <br />Northern Sweetvetch Hedysarum boreale Timp. 10.0% 1.50 <br />Rocky Mountain Penstemon Penstemon strictus Bandera 5.0% .75 <br />Scarlet Globemallow Sphaeralcea coccinea ARS2936 3.0% .45 <br />Prairie Wildrose Rosa Arkansana 8.5% 1.28 <br />Totallbs/ac 100% 15.01 <br />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
