Extensive pine forests dot the upland areas segmented by rivers and streams. Arguably the most important natural resource, these forests support the lumber industry that is still in practice today. The poor soils that inhibited a strong agricultural economy support this piney woods habitat, and help create the stunning splendor of the backwoods region. The flora supports a diverse array of fauna. Many species of birds, mammals, and reptiles inhabit the Piney Woods Region, including numerous threatened and endangered species.
