Baylands Habitats

The baylands form the transition between the uplands and the Bay. They consist of two major habitat types: tidal flats and tidal marsh (including the marsh channels that drain at low tide). The transition from tidal marsh to adjacent upland plant communities is a “fuzzy boundary” between the usual high water line and the maximum inland extent of tidal influence. Such transitions, or ecotones, are especially rich with native plants and animals.
