Wetland Inventory (NWI) Maps
The maps use a hierarchical classification structure to identify wetland and deepwater habitats according to system, subsystem, class, subclass and modifiers as defined by the U.S. Fish and Wildlife Service.
For a free NWI index map brochure that shows all of the NWI map location superimposed over a map of the state, please call or e-mail us your name and address.
If you know the NWI title of a particular map (also known as the "quad" or "quadrangle"), it can be ordered via the web. Enter the name of the map in the search box below and click the button.
Note: These maps are custom made and are not returnable.
