In recent years people's attitudes regarding wetlands have changed a great deal. Wetlands are no longer thought of as wastelands and producers of disease. The reason for this dramatic change in attitudes is the recognition of the important role they play in our environment. The importance of wetlands can be summarized as follows: 1) Wetlands affect the quality of water by acting as a filter and storing organic materials in the leaves of aquatic plants. 2) Wetland areas are also important as a natural ponding bases. These areas help recharge the water table and reduce peak storm water runoff flows, thereby reducing the flooding potential. 3) Wetlands provide an essential breeding, nesting, and feeding ground for wildlife. 4) Marshes occurring in upland depressional areas can reduce soil erosion by dissipating the velocity of the runoff. The size and location of wetlands are important in determining the value in maintaining water quality, minimizing flood damage, and preserving wildlife habitat. Prior ~o completion of a community storm water runoff plan, or wet- land study, all areas of 5 acres or more should be preserved because of their ability to perform those functions. The City of Ramsey has far more potential for using wetlands as part of their storm sewer system, however, all three communities should adopt regulations prohibiting the dredging or filling of wetlands without a permit. WOODLANDS A woodland differs from a forest because of its smaller land area and it also includes farm woodlots, shelterbelts, and windbreaks. A forest is a large expanse of trees consisting of wooded vegeation and related wildl.ife. A general tree cover includes the scattered trees in urban areas. While larger tracts of trees are protected by Federal and State preserves, a significant amount of our woodland areas are subject to the potential threat of urban develop- -13-
