[5] It is characterized by an open canopy of South Florida slash pine ( Pinus elliotti var. densa ), a patchy subcanopy of palms and shrubs, and an extremely diverse ...
The globally imperiled pine rockland community, which also encompassed the Florida Keys and The Bahamas, supported numerous endemic plant species; 20 percent occur nowhere else in the world. [7] The communities of the Miami Rock Ridge are maintained by wildfires, including natural fires caused by lightning strikes; this affects the vegetation ...
The most significant feature of the pine rockland ecosystem is the South Florida slash pine (Pinus elliotti var densa; also called Dade County pine) that reaches a height of 22 feet (6.7 m). Pine rockland communities require fire for maintenance; they have adapted to promote and resist fire at the same time. [50]
Prior to urban development of the South Florida region, pine rocklands covered approximately 161,660 acres (654.2 km 2) in Miami-Dade County. Within Everglades National Park, 19,840 acres (80.3 km 2 ) of pine forests are protected, but outside the park, 1,780 acres (7.2 km 2 ) of pine communities remained as of 1990, averaging 12.1 acres ...

Only 10% of pine rocklands remain globally, with less than 2% existing in Miami-Dade outside Everglades National Park. Despite that frighteningly low number, the remaining forests continue to ...
Burma reed is a grass with large, dry plume-like flowerets that invades the pine rockland ecosystem—one of the most endangered habitats in the state—feeding fires. While pine rocklands are maintained by fire, Burma reed can reach 12 feet (3.7 m) tall and burns so hot and high—flames can reach 30 feet (9.1 m)—that it can eradicate the ...
