Description:
Abstract:
The dataset delineates emergent tidal wetlands within the coastal zone of NH, including the Atlantic coastline from the Massachusetts to the Maine border, the NH side of the Pisquataqua River, Great Bay and its tributaries up to the head of tide, and the NH Isles of Shoals. In general the cover types are based on the US Fish and Wildlife’s wetland classification system developed by Cowardin et al. in 1979. The purpose of the project was to map all emergent tidal wetlands, with an emphasis on the invasive Phragmites (Phragmites australis) and purple loosestrife (Lythrum salicaria). Cattail (Typha angustifolia and occasionally T. latifolia) were delineated in large stands.
Purpose:
The New Hampshire Coastal Program requested an inventory and analysis of tidal wetlands compatible with NH GRANIT.

Data_Quality_Information:
Logical_Consistency_Report:
The current mapping effort used aerial photographs flown between August 4 and 9, 2004 by Sewall Co, Old Town, ME. The aerials are true-color positive transparencies, have a scale of 1:9600, and were flown during the lower half of the tide cycle. The transparencies are generally very high quality, although in some cases, the photos were taken early or late enough in the day that shadows prohibit detection of vegetation near the tree line. The delineations were made on acetate overlays which were then scanned, rubber-sheeted to fit 2003 orthophotos of the area, digitized, and analyzed using ArcView 9.1. Quality control was implemented at all stages of the process, including almost 100% QC of the photointerpretation, groundtruthing to verify representative cover types, and 100% of the digitizing and edit reviews for all changes in GIS. The QC was documented in hard copy whenever possible. The minimum map unit was typically 0.25 acres, although when smaller features were clearly visible, polygons less than 0.25 acres were created. In general the cover types are based on the US Fish and Wildlife’s wetland classification system developed by Cowardin et al. in 1979. Stands dominated by Phragmites (Phragmites australis), purple loosestrife (Lythrum salicaria), and cattail (Typha angustifolia and occasionally T. latifolia) were delineated and cover typed by species. Because of the brackish nature of these species and the salinity gradients in the study area, no attempt was made to determine whether they were Palustrine or Estuarine; they were simply recorded by species. Stands that consisted of several cover types or species are indicated by stripes of the appropriate colors.
