This map is a product of the U.S. Fish and Wildlife Service's National Wetlands Inventory (NWI) Program, Northeast Region. It was compiled from data derived through photointerpretation of 1991 and 1995 aerial photographs using Massachusetts state wetland data as the foundation. The effective date of the updated inventory is 1995. U.S. Geological Survey (USGS) Digital Line Graphs (1 :24,000-scale) were used to create a more complete data set. U.S.D.A. Natural Resources Conservation Service digital county soil survey data, USGS Digital Raster Graphics, and original NWI data were also used as collateral information.

The map was produced with the intent that it be used or displayed at a scale of 1 :45,000. There are no warranties as to the fitness of this map for any unlisted purpose or reproduction at any other than the original scale. NWI data are posted on the web at: http://wetlands.fws.gov.
