ABSTRACT
Several forested plant communities occur as tree islands in the Everglades. Wetland shrubs and trees found throughout the region’s swamps occur on all Everglades tree islands. In addition, some tree islands have ground rising above ordinary flooding elevations and support upland trees that only survive in aerobic (unsaturated) soils. The upland forest community is called a hammock. The kinds of trees in hammocks are covered in more detail in Chapter 5, but important ecological and anthropological roles of tree islands with upland areas are covered here. In contrast to tropical domination in the hammocks (especially those of the central and southern Everglades), most of the wetland species are of temperate, North American origin, and are common in swamps throughout the southeast. Common wetland tree island species of the Everglades are listed in Table 4.1.
