NST believes that there is a great opportunity to create natural shoreland buffers. This could be conducted in a way that would not compromise the play on Hole #5. The proposed upland buffer areas currently consist of manicured turf. Along the shore, there are small patches of native vegetation — manna grass, spike rush, , arrowhead, and at least two native sedge species. Site preparation would � consist of treating all turf areas, and working around all substantial patches of native vegetation along the shore. The goal is to preserve these remnant plants. After the site is tilled, we would use a mix of native seed and plants (form 3" to 1- gallon containers) to begin the revegetation process. The seed mix would be a custom blend that would take into account course site conditions and height considerations. After seeding, all restoration areas would be covered with a high quality, bio-degradable, erosion control blanket. Plant plugs would then be planted through the blanket. In the buffer design, we would introduce lower growing shoreland species along the pond adjacent to the fairway, e.g., common rush, sedge, and blue flag iris. Between the pond and drink stand (please see attached photo), we would establish a more diverse natural buffer, averaging 15' in width. All plants used in our restorations are Minnesota native species grown at our Maple Plain nursery. All plants carry a one-year warranty. In order to keep people and animals out of the restoration, a temporary fence would be installed. We use a green vinyl coated wire fencing that blends with the buffer areas. We also recommend that the site be monitored and maintained by our staff. We will closely monitor plant establishment and identify and remove invasive weed species.
