As a representative example of southern Crowley’s Ridge, where the Tertiary sands and gravels remain capped with loess, Wittsburg Natural Area preserves a mixed mesophytic forest that contains interesting plant species not represented elsewhere in the System of Natural Areas. For example, the natural distributions in Arkansas of tulip tree and pennywort are limited to Crowley's Ridge and both plant species occur in Wittsburg Natural Area. American beech and sugar maple are common as well. The Natural Area also includes almost the entire watershed for a small network of intermittent streams. The topography is deeply dissected and the upper slopes are extremely steep.

There is no public access to this natural area.
