Habitat:
The top and rim of the plateau, at about 2000 ft elevation, is covered by Quercus, Carya, Nyssa hardwood forest on thin, sandy soils overlying Pennsylvanian sandstone, conglomerates, and shales . The upper slopes support rich cove forests with Liriodendron, Acer, Tilia, and Magnolia, grading on the lower slopes into shorter, drier Juniper woodlands on well-drained thin soils overlying Mississippian limestone. The flat farmland below, at about 1000 ft elevation, is made up of Precambrian to Silurian materials.
