Exotic/Invasive Species
There are occurrences of exotic plant species within the park.  Privet is found in abundance, primarily in the forested buffer zone in the southern portion of the property.  Other escaped cultivars are likely to be present in this area as well.  Chinese Tallow (Sapium sebiferum) is present at the park in small numbers along the marsh edge and within the freshwater wetland areas of the moats and to the north.

Habitats & Communities
Three main habitats have been identified at Ft. Frederica:  Salt Marsh, Live Oak/Magnolia Forests, and Pine Successional Forests. 

Salt Marsh:  To the west of the Frederica River is a tract (roughly 100 acres) of salt marsh that includes both low and high-marsh communities.  Associated with these communities are mud flats.

Live Oak/Magnolia Forests:  Located around the maintained archeological area of the park this area is dominated by live oak, laurel oak, and pignut hickory.  At the Bloody Marsh tract, the forest is somewhat richer, including cabbage palm, slash pine, and persimmon.

Pine Successional Forests:   Located in southern portion of the park property and east of the park headquarters.  A wetter variant of the community also occurs on either side of the entrance drive.
