SPECIES CHARACTERISTIC OF THE APPALACHIAN PLATEAU
A significant portion of the southern part of the preserve system is on the Appalachian Plateau and there are a number of species characteristic of the Plateau that occur in this portion of the preserve system as well as some isolated populations north of SR 125. These species include Carex purpurifera, Coreopsis major, Prosartes maculatum, Kalmia latifolia, Lygodium palmatum, Magnolia acuminata, Paxistima canybi, Penstemon laevigatus, Polypodium appalachianum and Waldsteinia fragarioides. Most of the these species are rare in the preserve system and survive in narrow ravines or other uncommon habitats. Some of the Appalachian species likely entered Ohio via the Teays River and were isolated by the changes to the river system by the glaciers.
SPECIES CHARACTERISTIC OF THE INTERIOR LOW PLATEAU
Interior Low Plateau species are species characteristic of the Interior Low Plateau and adjacent regions to the west and southwest. These species are primarily prairie species.
Interior Low Plateau species include Aster oblongifolius, Castilleja coccinea, Draba reptans, Gentiana alba, Kuhnia eupatorioides, Leavenworthia uniflora, Synandra hispidula, Polemonium reptans var. villosum, and Solidago rigida. Leavenworthia uniflora and Polemonium reptans var. villosum are endemic to the Interior Low Plateau.
