Tree islands of the Florida everglades? Long-term stability and response to hydrologic change
Debra A. Willard
2004, Fact Sheet 2004-3095
Tree islands are important centers of biodiversity in the Florida Everglades; they have two to three times the plant and animal diversity of the surrounding wetlands. This high diversity is due primarily to their higher elevation relative to the adjacent wetlands (fig. 1). In the natural Everglades system, water levels...
