In south Florida, pine rocklands occur in Miami-Dade County, Monroe County, the Lower Keys, Everglades National Park, and Big Cypress National Preserve, but can also be found throughout the Caribbean Archipelago. Despite its range, the pine rocklands are limited in distribution.[4] Urban development, agricultural expansion, and extreme fragmentation since the late 1800s have severely reduced the extent of its range. 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 median being 1.7 ha.[8] The Long Pine Key portion in Everglades National Park still holds around 9915 ha, or 80% of all pine rockland found in Florida.[7] Limited reserves found in the Lower Keys are decreasing due to fire suppression and salt-water intrusion via rising sea levels.[9]
