Each figure is the acreage inside Pennsylvania for one kind of unit, summed over the units listed below. A unit that crosses into another state counts only the part of its boundary that lies in Pennsylvania. Wilderness often lies inside one of the other kinds, so the figures overlap and should not be added together.
