In addition to pine flatwoods characterized by an open canopy forest, and hardwood hammocks, with their ancient oaks and relatively open understory, Split Oak Forest contains several less common communities. These include oak scrub (with low canopy of myrtle oak, Chapman's oak, and sand live oak), and the sandhill community, consisting of scattered longleaf, pine and turkey oak with wiregrass and palmetto understory.
Pine flatwoods community
Split Oak Forest is bordered by Lake Hart to the north and Lake Mary Jane to the northeast. The wetland fringes of both lakes are habitat for a large number grasses, wild flowers, and shrubs. The area also includes cypress swamps and wet prairies, which are seasonally flooded transitional areas between freshwater marshes and pine flatwoods.
