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 />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 />( OIIlI110I1 Nallle <br /> <br />i <br />Western Wheatgrass -_ - _ _ <br />Scientific Nai11C <br /> <br /> <br />Agropyron smithii - - <br />N arlet. <br /> <br /> <br />Arriba <br /> <br />t <br />/ <br />N fix <br />17.0% PLS <br />pF <br />licatioll <br />Rate (Fbs/ac) <br />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 />Notes: <br />1.
