Nature Preserve Area:
Location and Access:
From Millstadt, take Highway 158 two miles to a county road. Turn north on this road and go two miles (the road goes north 0.5 mile, then west 0.5 mile then north again for 1 mile). Turn west on this county road and go 0.5 mile. The preserve is on the south side of the road.
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.
