Accruate mapping of tidal wetlands is vital for effective conservation and restoration of these valued habitats, and good mapping is key to strategic planning for coastal resilience. Tidal wetlands are defined by regular inundation by the tides; therefore, mapping of tidal wetlands should be based on knowledge of tidal water levels and the land areas inundated by the tides. We developed this tidal wetland mapping following that principle. Briefly, we used a method developed in Oregon that combines NOAA’s extreme water level models with high-resolution LIDAR digital elevation models (DEMs) to map areas subject to tidal inundation. We refined the mapping using additional data sources such as the National Wetland...
