This helps explain why the pine rocklands are home to a wide variety of plants and animals, many of which are endemic to Florida, south Florida, or the pine rockland itself. [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 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]
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 ...
Its natural habitat is areas of coastal hammocks and pine rocklands. [4] It is a small tree or shrub with thick evergreen leaves. It produces small yellow flowers throughout the year, and has large scaly fruits. [5] This species is divided into four well-marked subspecies, which show little geographic overlap. They are: [6]
The Key deer is restricted to pine rocklands and tropical hardwood hammocks on Big Pine Key. Both the Key Largo cotton mouse and the Key Largo woodrat are endemic to tropical hardwood hammocks on Key Largo in the upper Florida Keys. The Stock Island tree snail is historically known only from hammocks on Stock Island and Key West.
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 ...

In southern Florida, in Miami-Dade County, including Everglades National Park, it is a serious threat to the globally imperiled pine rocklands community whose pine canopy was largely destroyed in 1992 by Hurricane Andrew. Burma reed is a highly combustible fuel source because of its high overall plant mass, its large feathery flower plumes, and ...
