Tidal wetland systems are important transitional habitats between the ocean and land. Salt marshes in particular provide essential functions and values from a human perspective. They support healthy fisheries, protect shorelines from erosion, reduce flooding, protect water quality, and provide essential fish and wildlife habitat. This data set is intended to establish a baseline to document statewide tidal wetland change over time. It focuses on salt marsh system response to relative sea level rise, documenting both changing quality and quantity of this habitat. Data was derived from high resolution multispectral orthoimagery collected on August 24, 2013 through the Piscataqua Region Estuaries Partnership and LiDAR data collected through the LiDAR for the NorthEast project (2011). Draft maps were created in 2015 and accuracy assessments continued until 2018. These data are currently not available to download from the GRANIT website. |
