The above procedures may be modified as conditions dictate. Russian Olives existing prior to mining will not be removed by Lafarge. If a significant invasion of noxious weeds occurs, the area will be mowed periodically for control. Weeds will be mowed before they go to seed during the first growing season. Mechanical control will be used as a first priority. Chemical methods will be used only if no other alternative produces acceptable results. Marsh and aquatic plants are expected to establish themselves along the shoreline of the post- mining pond. The species of plants anticipated to establish themselves naturally along the pond shoreline include cattails, willows, cottonwoods, and bulrushes. The existing riparian areas along the Cache la Poudre River would function as a seed bank for the pond area. These plants should minimize shore erosion potential. The following are the proposed seed mixtures to be used on site where appropriate. However, availability may dictate the need for variety substitution.
