Allegheny-Cumberland dry oak forest and woodland
The Allegheny-Cumberland dry oak forest and woodlands are typically dominated by white oak (Quercus alba), southern red oak (Quercus falcata), chestnut oak (Quercus prinus), and scarlet oak (Quercus coccinea). Less frequent are red maple (Acer rubrum), pignut hickory (Carya glabra), and mockernut hickory (Carya tomentosa).
Shortleaf pines (Pinus echinata) or Virginia pines (Pinus virginiana) are occasionally present, particularly near escarpments or in recently burned areas. In areas that have not recently burned, white pines (Pinus strobus) may be prominent. Sprouts of chestnut (Castanea dentata) can still be found in areas where it was formerly common.
On more base-rich substrates, this system transitions to Southern Ridge and Valley/Cumberland dry calcareous forest. To the east and north, it borders the Central Appalachian dry oak-pine forest, generally along the Allegheny Front.
