The U.S. Fish and Wildlife Service established the National Wetlands Inventory (NWI) in the mid-1970s to map the nation's wetlands and deepwater habitats. Since then, the NWI has completed at least one phase of mapping for all northeastern states, except New York where roughly three-quarters of the state has been inventoried. For most areas, NWI maps have been converted to digital geospatial data which facilitates generation of acreage summaries of the NWI findings. State reports have been published for several states (Rhode Island, Connecticut, New Jersey, Delaware, and Maryland) and acreage summaries published for most other northeastern states. Since these reports were published, NWI data have been updated for many areas. This report summarizes current NWI data (as of September 2090) for each state from Maine through Virginia and the District of Columbia.
