Pine Rocklands are unique to southern Florida and the Bahamas. In Florida, they are found on limestone substrates on the Miami Rock Ridge, in the Florida Keys, and in the Big Cypress Swamp. A single canopy tree dominates Pine Rocklands, South Florida slash pine. Fire is required for the maintenance of the Pine Rockland community. It influences species composition, controls the invasion and growth of hardwood species, allows light to reach the understory, and allows for pine regeneration. The prescribed burns range from 3 to 15 years in the Pine Rocklands. Review the image you see here. Based on your knowledge of succession, describe what is occurring here.
