Alice Wainwright Park's Natural Forest Community is a Tropical Hardwood Hammock. One of the remnant fragments of historical Brickell Hammock, one the largest and most diverse Rockland hammocks on the South Florida mainland. These upland hardwood forests occur only in South Florida and along the Florida coastlines. Once wide spread, today tropical hardwood hammocks occur primarily as remnant habitats in extreme South Florida and in small preserves along the southern Atlantic coast. These habitats are characterized by tree and shrub species on the northern edge of a range that extends southward into the Caribbean. This cold-intolerant tropical community has very high plant species diversity.
