Pine rocklands are a globally critically imperiled ecosystem with limited geographic range, characterized by a high biodiversity of endemic herbaceous plants and frequent fire intervals (2-5 years). In Miami-Dade County, approximately 2% of the forest outside Everglades National Park (ENP) remains. The County adopted a forest property tax program in 1979, passed a forest preservation ordinance in 1984, and created a land acquisition program in 1991. Outreach and filling in the gaps between preservation areas are critical for the survival of a number of species.
