National Wetlands Inventory

The National Wetlands Inventory (NWI) is a program led by the U.S. Fish and Wildlife Service that maps and assesses wetland areas across the United States. Wetlands, which include swamps, marshes, and bogs, play a crucial role in protecting water quality, providing wildlife habitats, and absorbing floodwaters. The NWI helps inform conservation efforts, land-use planning, and resource management by providing detailed information about the location, type, and condition of wetlands. This inventory supports research and awareness of the importance of wetlands in maintaining ecological balance and promoting sustainability.
