Native Plant Communities
Pine rockland is found in subtropicalclimate zones. It occurs at elevations 3 to 8 feet above mean sea level. Pine Rockland is characterized by an exposed limestone substrate often with solution holes and usually underlain by a freshwater lens. (https://www.fws.gov/refuge/National_Key_Deer_Refuge/wildlife_and_habitat/pine_rockland.html). It is mesic to xeric. Fire is frequent. Other disturbances include hurricane winds, and in some cases, rare inundation by salt water during storm surges.
Typical vegetation consists of south Florida slash pine, palms such as thatch palms, and subtropical hardwoods. The groundcover is and mixed grasses, herbs, herbs and low shrubs including pineland noseburn and Christmas berry. Pine rockland has the highest plant diversity of all plant communities in the Florida Keys. A total of 250 species of plants has been identified in the pine rocklands of south Florida and the Lower Keys. Many are rare (Bradley and Gann 1999).
Exellent examples occur in the Everglades national Parkand on Big Pine Key in the Key Deer National Wildlife Refuge.
