6.4.5 Exhibit E - Reclamation Plan <br />be completed as the quality soils and availability of water should facilitate the <br />rapid establishment of perennial grasses. <br />Following revegetation, weed management strategies will be implemented to <br />facilitate and achieve native grassland. Years 1 thru 5 following revegetation will <br />include an aggressive mowing program to prevent the growth and establishment <br />of weeds, specifically, eight noxious weeds including: Canada thistle (Cirsium <br />arvense), Dalmation toadflax (Linaria dalmatica), diffuse knapweed (Centaurea <br />diffusa), leafy spurge (Euphorbia esula), musk thistle (Carduus nutans), Russian <br />knapweed (Centaurea repens), spotted knapweed (Centaurea maculosa) and <br />Yellow toadflax (Linaria vulgaris) as mandated by Colorado State Law (35- <br />5.5CRS1990, 1996). If needed, herbicide application will be applied as needed <br />to further control these weeds. Herbicides will also be used to control salt cedar <br />(Tamarix spp.) if it becomes established in the reclaimed area. Table 6 presents <br />recommended herbicides, application rate, and time of application for each of the <br />9 species. It may be necessary to replant treated areas. <br />Table 6.4.5-6.
