MN 55391 Dear Lili; I have reviewed your plans for wetland enhancement for your site at 1275 Lyman Avenue in Orono It is my opinion that your efforts will result in improved wildlife habitat The .vetland also will not affect the area of wetland outside of your property. The wetland wildlife habitat will be improved through an increase in open water. A mix of open water and wetland vegetation provides cover and access to food, such as Duckweed, and is optimal waterfowl habitat. The design of the pond also lends to increased habitat dweisity. The edge of the open water is irregularly shaped, as recommended by Department of Natural Resources guidelines. The undulating bottom also provides enhanced habitat for amphibious species. Your plan to eliminate exotic and invasive plant species will increase the habitate value of the entire wetland. Purple Loosestrife is a dominant species in the interior of the wetland. Reed Canary Grass is common along the margins of the wetland. Prairie Restoration's. Inc. is. experienced in eliminating and controlling these species. Purple Loosestrife and Reed Canary Grass have out competed native species and reduced the quality of large portions of the wetland. Prairie Restoration's mix of naiive grasses will reduce the ability of Reed canary Grass to colonize this area of the wetland. In addition, restoration of native grasses in the adjacent upland, as planned, will control any non-point source run-off from entering into the wetland. It will also increase tfia biological diversity and value of this non-wetland area. Finally, the entire wetland is apprximately 30 acres in area. The excavation of .12 acres in a 30 acre v;etland will have virtually no affect upon the hydrology of this area. Mapping Inventories Delineations Permits
