We review the historic and recent knowledge of pine communities of the southeastern Coastal Plain with emphasis on their classification, structural attributes, dynamics, and resource management. The uneven attention of past research on these communities limited the descriptive details that may be provided on each community and pointed to research needs of the future. Our review is a companion to Chapter 10. We emphasize the pine ecosystems of Florida: pine flatwoods, longleaf pine-turkey oak sandhills, sand pine scrub, scrubby flatwoods, and subtropical pine forests. Of these, Küchler (1964) recognizes the sand pine scrub of central Florida and the subtropical pine forests of south Florida (Fig. 1). We provide maps of flatwoods and longleaf pine-turkey oak communities. They are more extensive than sand pine scrub and subtropical pine forests, but Küchler (1964) includes them within the Southern Mixed Forest. This chapter and Chapter 10 show that such a classification greatly oversimplifies the complex vegetation structure and history on the lower Coastal Plain.
