"The U.S. Fish and Wildlife Service is the primary federal agency that provides information on the state of the country’s wetlands, and this site provides extensive geospatial data on their current extent and location." Highly productive ecosystems, wetlands are so important in providing habitat and renewal of groundwater. There is a "Wetlands Mapper" and images from Google Earth. Digital wetlands data is downloadable by state or quadrant.
