The pine-hardwood forests are dominated by species such as white pine and yellow birch (Betula alleghaniensis), mixed with scattered red maple, a shrub layer dominated by witch-hazel (Hamamelis virginiana), and a herbaceous layer composed of a variety of herbs, mosses, and lichens.
In addition, red maple (Acer rubrum), sweet birch (Betula lenta), and yellow birch (Betula alleghaniensis) are common; sugar maple (Acer saccharum) is occasional. In areas that have been recently disturbed, white pine (Pinus strobus), Virginia pine (Pinus virginiana), or tulip tree (Liriodendron tulipifera) can be abundant.
