Deep acid sand with virtually no organic matter content except for surface litter. Soils are infertile and extremely well-drained, being low in moisture retention. Plants require good drainage and suffer from flooding and wet or heavy soils. Plants are drought and frost resistant and can endure light shade and slight salt exposure. Sandhill burns every 1-10 years, preventing hardwood succession. Plants are tolerant of frequent fires. Sandhill grades into pine flatwoods.
