Wetland complexes were constructed from the National Wetlands Inventory (NWI) base layer completed by US F&WS in the mid-1980's. This derived coverage was created by constructing wetland complexes from the individual NWI wetland polygons in accordance with the 2010 "Method for the Comparative Evaluation of Nontidal Wetlands in New Hampshire" (NH Method). Complexes bisected by large roads and rivers were split into seperate wetland complexes. Once the complexes were created, an Assessment Unit ID (AUID) was assigned to each fresh water and estuarine wetland complex acording to the primary hydrologic unit boundary at the subwatershed (12-digit) level that it resided in.
