Establishment <br />failure can occur for a variety of reasons, including compacted soil conditions, flooding, drought, and <br />extensive weed competition. Depending on the reason(s) for failure, recommendations may be provided <br />to adjust species in the re-seeding mix to better accommodate growing conditions in the specific area. <br />6.3 Seed Establishment Techniques (Establishment Phase) <br />A variety of vegetation establishment techniques should be implemented on the Site. Methods will be <br />selected to provide the best control possible of noxious, invasive, and woody species while minimizing <br />impacts on seeded species. <br />6.3.1 Control and Prevention of Invasive Species <br />Noxious, invasive, and undesirable plant species will be controlled, including all species listed on the <br />state noxious weed list maintained by the MDA in accordance with State of Minnesota noxious weed <br />rules and regulations. Invasive plant species as listed by MN DNR may be controlled as appropriate for <br />Project objectives. During the establishment phase, efforts to prevent and control the spread of invasive <br />species will likely require a combination of herbicide use and mechanical mowing. Prescribed burning <br />or other methods described in Section 6.4 may also be considered.
