Wetland Communities - Hydric Pine Flatwoods
 

Hydric Pine Flatwoods are forests with a canopy of slash pine (Pinus elliottii) or pond pine (Pinus serotina) on flat, poorly drained land. Where fires are frequent, the subcanopy is sparse or absent and the groundcover is a diverse mix of grasses and herbs—a wet prairie with pines. Common groundcover plants include wiregrass (Aristida stricta), yellow-eyed grass (Xyris spp.), meadow-beauty (Rhexia spp.), bog-buttons (Eriocaulaceae), and carnivores like pitcher plants (Sarracenia spp.), sundews (Drosera spp.), and butterworts (Pinguicula spp.). Saw palmetto (Serenoa repens) is patchy or absent. Where fire has been suppressed, shrubs and trees like titi (Cyrilla racemiflora and Cliftonia monophylla), gallberry (Ilex glabra), big gallberry (Ilex coriacea), myrtle-leaved holly (Ilex myrtifolia), sweet bay (Magnolia virginiana), black gum (Nyssa sylvatica var. biflora) and swamp bay (Persea palustris) become dense and the groundcover disappears. Dense tangles of laurel-leaved greenbriar (Smilax laurifolia) often drape these shrubs. The longer fire is excluded, the more these flatwoods approach bay swamps. Hydric pine flatwoods are common throughout the lower parts of the panhandle, especially near the coast, and are absent in the higher clayey land toward the Georgia and Alabama lines.
