Cluster analysis based on tree species produced three general community types: 1) Quercus stellata-Q. marilandica forests; 2) Q. stellata forests; and 3) mesophytic forests. A polar ordination produced a gradient of vegetation that corresponded to a moisture gradient. Many high diversity forests were located on loamy drainageway soils or north facing slopes. Tree species diversity (H') was inversely related to the importance of Quercus stellata. Cluster analysis based on species composition of the tree seedlings produced four general community types: 1) Q. marilandica type; 2) Q. marilandica-Q. stellata-Juniperus virginiana type; 3) Ulmus americana-Celtis reticulata-Bumelia lanuginosa type; and 4) Acer saccharum type. The third seedling type occurred almost exclusively on loamy drainageway soils. There was no relationship between stand location on the first axis of the tree ordination and the first axis of the seedling ordination suggesting that trees and seedlings respond differently along the moisture gradient.
