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.
