Description
On this site, a cypress - tupelo freshwater forested wetland consists of depressions dominated entirely by cypress or tupelo, or these species are important in the canopy; long hydroperiod. This site type includes dome swamps, and basin swamps. (FNAI, 2010).

Description
Pine plantations in Florida are often dominated by evenaged loblolly, sand, or slash pine (Pinus taeda, P. clausa, or P. elliottii, respectively). Dense pine plantations typically have sparse to absent herbaceous vegetation as a result of shading or a cover of deep pine needle duff. These plantations may be very shrubby or vine-dominated or open at ground level. The groundcover in most cases has been severely impacted by mechanical site preparation, such as roller chopping and bedding. However, while perennial grasses such as wiregrass (Aristida stricta var. beyrichiana) may be greatly reduced, many components of the native groundcover persist even though the relative abundance is altered. Groundcover can be partially restored by thinning and/or frequent burning, although some planting of perennial grasses such as wiregrass may be required. (FNAI, 2010)
