In less than a day and with just a steel-tired tractor and a push blade, the Nebraska Department of Roads created undulated surfaces on 50 acres of the Tarnov Wetland Bank Site near Platte City, Nebraska. The small rises and declines - from six inches above to six inches below the design elevation - helped set up the specific moisture conditions needed for diverse vegetation that would appeal to a wide variety of aquatic insects and wildlife species. In just two growing seasons, the site changed from bare ground to a canopy of sedges, cattails, duckweed, spikerush and other wetland plants. The wetland attracts such wildlife species as deer, snow geese, white egrets, great blue herons, and mallard and blue-wing teal ducks.
