Maritime Forests and Dunes
Live Oak Forests and Maritime Scrub Thickets
General Description The evergreen oaks, shrubs, and other vegetation, along with their symbionts, are typically thought to be associated with barrier islands, making up the Maritime Forest natural community type. While there is a strong concentration of these habitat in the Tidewater region of the state, most of the members of this habitat type extend inland to some extent, with some reaching as far west as Robeson, Bladen and Cumberland Counties in the Inner Coastal Plain.

All are associated with sandy habitats and as barrier island species must cope with at least some degree of salt spray and the damage caused by hurricanes. Inland examples occur along rivers in the form of evergreen hammocks, again on sandy substrates. Some of the species are also found on the xeric sand rims of Carolina Bay, with a few species in this group extending into the Fall-line Sandhills.
