Down on the floodplain the associated vegetation is typical of most bottomland hardwood systems of the lower gulf coastal plain. It includes trees such as water hickory, baldcypress, sycamore, green ash, hackberry, American elm, sweetgum, honeylocust, and live oak. Shrubs like dwarf palmetto, dewberry, deciduous holly, Chinese privet and water elm are also located here. From an ecological standpoint, the most important vegetational component of both forest types are the vines. At least two dozen species of herbaceous and woody vines can be found coursing their way through all layers of the forest.
Ferns are also quite showy during almost every month of the year.
