Description:

Abstract:

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.

Purpose:

This base layer is intended to act as a starting point for anyone applying the NH Methods. The layer provides a unique code to each wetland complex in New Hampshire, for use in assessing water quality and other attributes of wetland complexes.

Use_Constraints:

The New Hampshire Department of Environmental Services, Watershed Management Bureau, Water Quality Planning Section, should be acknowledged as the data source in products derived from these data. The US F&WS should be acknowledged as the originators of the NWI.

This data set is to be used as a primary reference source. This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application. Federal, state, or local regulatory bodies are not to reassign to the New Hampshire Department of Environmental Services any authority for the decisions they make.

Photographic or digital enlargement of these maps to scales greater than that at which they were originally delineated can cause misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the small scale. Digital data files are periodically updated, and users are responsible for obtaining the latest version of the data.
