What Is the National Wetlands Inventory?
In 1974, the U.S. Fish and Wildlife Service (USFWS) established a nationwide inventory of wetlands (National Wetlands Inventory [NWI]) with the intention to provide information on the distribution and type of wetlands that can be found in the U.S. This inventory of wetlands can be used by federal, state and local governments, private industry, and non-profit organizations as baseline information for wetland regulation and management decisions, land use and conservation planning, environmental impact assessments, and natural resource inventories. Along with the NWI providing insight for decision-making, this data is also available to the public and can be accessed nation-wide through the National Map.
