Book Description
The NWI Program mapped about 2.04 million acres of wetlands and over 1 million acres of deepwater habitats, excluding marine waters. The wetland mapping is conservative due to limitations of the photointerpretation techniques employed. Considering NRCS hydric soil data and the results of a wetland map assessment done for the LURC region, the actual extent of wetlands in Maine is likely somewhere between 3.28 and 3.75 million acres, representing 17-19% of the state's land area.

Book Description
The U.S. Fish and Wildlife Service (FWS) has been conducting a nationwide survey of wetlands and deepwater habitats since the mid-1970s through its National Wetlands Inventory Program (NWI). This survey is accomplished using traditional photointerpretation techniques to produces map and digital geospatial data on the status of wetlands. The U.S. Geological Survey topographic maps serve as the base data upon which boundaries of wetlands and deepwater habitats are delineated.

Book Description
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.
