| Notes | “Geographic Information Systems (GIS) layers of current, and likely former, tidal wetlands in two Oregon estuaries were generated by enhancing the 2010 National Wetlands Inventory (NWI) data with expert local field knowledge, Light Detection and Ranging-derived elevations, and 2009 aerial orthophotographs. Data were generated for two purposes: First, to enhance the NWI by recommending revised Cowardin et al. (1979) classifications for certain NWI wetlands within the study area; and second, to generate GIS data for the 1999 Yaquina and Alsea River Basins Estuarine Wetland Site Prioritization study…. The GIS products of this project improve the accuracy and utility of the NWI data, and provide useful tools for estuarine resource management.” (from the Abstract) Color maps. Appendix A includes excellent color photographs of wetland sites and plants. |
