In areas that are peripheral to the post-mining lake, marsh and aquatic plants are expected to <br />establish themselves. The species of plants anticipated to occur naturally along the lake shoreline <br />include cattails, willows, cottonwoods, and bulrushes. These plants should minimize shore erosion <br />potential. The following are the proposed seed mixtures to be used on site where appropriate. <br />However, availability may dictate the need for variety substitution. <br />Seed Mix for Upland Areas <br /> <br />Common Name <br />Scientific Name <br />Variety <br /> <br />-- - of <br /> <br />Mix <br />- -- PLS1 <br />ApplicationI <br /> <br />'Rate (lbs/act ? <br />Western Wheatgrass Agropyron smithii Arriba 17.0% 1.74 <br />Sideoats Grama Bouteloua curti endia 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 />1 Pure Live Seed pounds per acre; rates shown are for drill seeding; double rates for broadcast <br />seeding. <br />Seed Mix for Transitional Zone/Water's Edge <br /> <br /> <br />Common Name <br /> <br />Scientific Name <br /> <br />Variety <br /> <br />of <br />Mix PI'S <br />I <br />Application <br /> <br />Rate Ibs/ac <br />Western Wheatgrass Agropyron smithii Arriba 10.6% 1.45 <br />Side Oats Grama Bouteloua curti endia Butte 9.2% 1.24 <br />Canada wildrye Elymus canadensis Mandan 18.1% 2.47 <br />Basin wildrye Elymus cinereus Magnar 9.8% 1.34 <br />Switchgrass Panicum virgatum Pathfinder 5.7% 0.78 <br />Sand dropseed S orobolus cryptandrus 0.2% 0.03 <br />Scarlet Globemallow Sphaeralcea coccinea ARS2936 3.8% 0.52 <br />American vetch Vica americana 42.6% 5.81 <br />Totallbs/ac 100% 13.64 <br />Parsons Mine <br />DRMS 112 Reclamation Permit Application <br />Page E6 of E8
