A wide range of habitats includes the pinelands, lowland swamps, freshwater marshes, salt and freshwater tidal marshes, barrier islands (sandy beaches and dune habitats), shallow bays and the coastal ocean. Little more than one percent of this reserve has been subject to human development. The area is one of the least disturbed estuaries in the densely populated urban corridor of the northeastern United States.
