P. e. var. densa (South Florida slash pine, Dade County pine) is found in the pine rocklands of southern Florida and the Florida Keys, including the Everglades. [10] [11] Leaves are nearly all in bundles of two, with longer needles. The cones are smaller, 5–12 cm (2.0–4.7 in), the wood is denser, and the tree has a thicker taproot. [9]
Of the original estimated 65,450 ha of Miami-Dade County pine rockland, around 920 ha, or 2%, remain outside of Everglades National Park. [7] The remaining fragments scattered across the county are protected as public parks or Environmentally Endangered Lands and range in size from 0.1 ha to 324 ha, with the average size being 6 ha and the ...
Miami-Dade County was once covered in 186,000 acres (290.6 sq mi; 752.7 km 2) of pine rockland forests, but most of it was harvested by the lumber industry. [30] Pineland ecosystems (or pine rocklands) are characterized by shallow, dry sandy loam over a limestone substrate covered almost exclusively by slash pines ( Pinus elliottii var. densa ).
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]

At the beginning of World War II, the United States Navy purchased 2,500 acres (1,000 ha) of land in southwestern Dade (now called Miami-Dade) County for the purpose of constructing an airship base. The land was owned by the Richmond Timber Company, a major supplier of Dade County Pine (a denser, harder, sub-species of Pinus palustris , or ...
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 ...
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 ...
