In recent years a new threat to the natural environment has appeared in southeastern Florida. Areas of the rocky southwest of Homestead which seemed safe from exploitation for years to come are now being intensively farmed by a technique called "rock farming." This consists of breaking up the surface of the Perrine rockland with bulldozers and other heavy machines and using the resulting fragments of limestone to support various winter crops. The native vegetational associations—largely fire-adapted xeroseres—cannot survive this massive change in the substrate, and even if the "rock farms" are abondoned the original pinelands will have disappeared over considerable areas.
