Emery Woods is a Quercus-Acer saccharum-Carya forest that meets criteria for old growth. Ordination analysis indicates that variation in tree composition is related to slope exposure. Size class analysis indicates that the current canopy composition has a high potential for change, as Acer saccharum is expected to gain in importance while without larger-scale disturbance most Quercus spp. and Carya spp. may be lost from the canopy, resulting in a lower tree diversity. We collected 219 vascular plant species from 69 families.
