Wetlands, in a wide variety of forms, are found throughout the country. The various values of these areas have been increasingly recognized in recent years, but the remaining acreage has been disappearing rapidly. When European settlers first arrived, total wetland acreage was more than 220 million acres in the lower 48 states, according to estimates by the U.S. Fish and Wildlife Service. By 1980, total wetland acreage was estimated to be 104 million acres. Losses continue, although the rate of loss hasslowed considerably during the past decade. Recent losses have been concentrated in the lower Mississippi River Valley, the upper Midwest, and the Southeast.
