The south Florida pine rockland is unique geographically. Southern Florida is located at the southern end of the temperate North American Floristic Region and at the northern end of the tropical Caribbean Floristic Region.[13] This location allows for the mixture of vegetation from two distinct areas at the extremes of their ranges.[14]  Around 9% of all pine rockland plants found in Miami-Dade County alone are endemic to Florida, and around 14 taxa are endemic to the Miami-Dade pine rockland itself.[15][16] Overall, there are over 537 plant species found throughout the south Florida rocklands.[17]
