This old growth forest remnant is located on a sinkhole plain near the entrance to Stemler Cave. This dry upland forest community contains white oak, post oak, red oak, pignut hickory and white ash. Several sinkholes create localized variations in topography and microclimate, resulting in a change in the species composition of the forest near these sites. White and black oaks are most common on the upper two-thirds of the sinkhole while red oak is common in the lower one-third of these depressions.
