Most of the farms are part-time or subsistence farms. The area is a dissected rolling to hilly upland. In many of the more dissected sites, there are stablized dunes, resulting in very irregular slopes. Local relief is mainly several meters, but a few hills are 25 to 50 m above adjacent areas. Average annual precipitation -1,150 to 1,275 mm.
Maximum precipitation is in midsummer, and the minimum is in autumn.
The kind and amount of plant growth is severely limited by low moisture in the rapidly permeable soils that are dominant in this area. The dominant soils are Psamments and Udults. They have a thermic temperature regime and an udic moisture regime. Longleaf pine is the dominant species. Turkey, blackjack, bluejack, and sand live oaks are included.
