When you think of a wetland, what comes to mind? A grassy, freshwater marsh with flocks of ducks, geese, and other waterbirds…coastal marshes filled with fishes… brackish channels lined with mangroves. Wetlands include all of these habitats and more such as swamps, bogs, fens, prairie potholes, and even seasonal wetlands like vernal pools. A wetland is an area that is saturated or covered by water at least part of the year. Wetlands provide vital habitat, food, and water for thousands of plant and animal species. Humans also rely on wetlands for food, to replenish groundwater, for improving water quality, for flood control, to prevent soil erosion, and for recreation. In this issue of Land, Sea & Air you and your class can take a virtual field trip to explore the world of wetlands.
