BD - Beach Dunes

Beach

IZ - Intertidal zone

Unconsolidated shoreline, unconsolidated substrate, beach, tidal flat.

MOL - Oyster reefs

Mollusk reef, oyster bed

FL - Intertidal flats

Unconsolidated substrate, saltflats, mudflats, tidal flats.

DV - Developed

Urban, developed sites.

EMm - Managed marsh

The marshes surrounding these open water sites have been impacted by the flooding regimes and saltwater exchange allowed in these areas. Most recently, a significant amount of cattail (Typha spp.) was reduced by humans as a result of flood management projects.

UBm - Managed open water

The vegetation, predominately submerged vegetation, will be impacted as flooding regimes and salinities change with management activities.
