Descripción:
Pine rockland occurs in subtropical climate zones at elevations of 3–8 feet above mean sea level. It is characterized by an exposed limestone substrate, often with solution holes, and typically underlain by a freshwater lens ( U.S. Fish & Wildlife Service ). The community ranges from mesic to xeric and is maintained by frequent fire. Other disturbances include hurricane winds and, occasionally, saltwater inundation during storm surges.
Vegetation is dominated by South Florida slash pine ( Pinus elliottii var. densa ), with palms such as thatch palm ( Thrinax radiata ) and various subtropical hardwoods. The groundcover consists of mixed grasses, herbs, and low shrubs, including pineland noseburn ( Tragia saxicola ) and Christmas berry ( Crossopetalum ilicifolium ). Pine rockland supports the highest plant diversity of any plant community in the Florida Keys, with more than 250 plant species documented (Bradley & Gann, 1999). Many of these are rare or endemic.
Excellent examples of pine rockland occur in Everglades National Park and on Big Pine Key within the National Key Deer Refuge.
