Coastal Classifications


The maps provided in this section provide a graphical depiction of three habitat categories. Tidal creeks are defined as those estuarine water bodies that intersect marsh habitat and are less than 100 m in width from marsh bank to marsh bank. Open water habitats include all other water bodies. Shallow habitats represent portions of the state's coastal waters that are too shallow to sample at low tide or are otherwise physically unavailable to station visits by boats. These areas are excluded from the station selection process. Each habitat was defined using one or more of the following Geographic Information System (GIS) coverages: Hydrography Digital Line Graphs (DLG), National Wetland Inventory (NWI) 1994 database, USGS Digital 7.5' Topographic Quadrangle Maps (1994), and the Coastal Change Analysis Program (CCAP) 1995 database.

Disclaimer: Due to the size and complexity of South Carolina's estuarine wetlands, both SCDNR and SCDHEC staff recognize that some areas may be misclassified. Areas where sampling is attempted, but is unsuccessful, will be modified periodically with respect to habitat designation. The map products provided in this section were created solely for the purpose of conducting the South Carolina Estuarine and Coastal Assessment Program (SCECAP). Their accuracy and the habitat designations depicted do not necessarily reflect the views of, or represent the official position of the SCDNR, SCDHEC or the State of South Carolina with respect to the use of these habitat classifications for other purposes.
