Rare in its natural habitats in Florida and Alabama in the US
Distribution Overview
This species occurs almost exclusively in Florida, where it is found in two separate regions about 125 miles (200 km) apart. Primary growth site is in central Florida, and the secondary site is located in the western part of the state. The species grows from sea level to an elevation of about 200 feet (60 m). Its range extends to Fort Lauderdale on the Atlantic Coast, and to Tampa on the Gulf Coast. The species is also reported to extend westward into Alabama. Sand pine trees growing in the western part of its range are typified by cones that open when mature, but those growing in central Florida are reported to open and release their seeds only after a severe fire sweeps through its range. The habitat in both areas are, however, believed to be fragmented and are continually being depleted by development. The tree prefers well-drained sandy soils, and is often found in pure stands.
