Managing Moist Soil Areas

Managing Moist Soil Areas. . , Refuge Wetlands Set the Table for Wildlife , The Neosho River floodplain was once covered with hundreds of shallow wetlands. As wetlands dried from spring into summer, seed-producing plants would grow. Fall rains recharged the water supply to these wetlands, providing waterfowl with the food and cover they need during migration., Although most of these natural wetlands are gone, the Refuge has built new wetlands, called moist soil units, that are managed to mimic the natural wet and dry cycle that once existed., How Does It Work? , Moist soil units are managed intensively through a series of levees, pumps, and water control structures. In the fall, wetlands fill with rainwater or with water pumped from the Neosho River and Eagle Creek. In the late spring, water is slowly released to allow wetland plants like smartweed, pigweed, and bidens to grow and produce seeds. The wetlands are filled again the next fall. When flooded, these plants and their seeds give waterfowl the high-energy food they need for their journeys between their wintering and breeding grounds., Moist soil plants produce the most seeds early in their life cycle. Discing, mowing, and prescribed fire are used to remove older plants and stimulate new growth as well as discourage tree growth in these areas., Buffet for Wildlife , Many wildlife species take advantage of the rich benefits these wetlands provide. Frogs and small fish are food for hawks, egrets, and herons, while beetles and snails provide a vital source of protein for shorebirds. The food these wetlands produce gives many birds the essential protein needed for migration and to produce young.
