Associated Forest Cover
Butternut is found with many other tree species in several hardwood types in the mixed mesophytic forest. It is an associated species in the following four northern and central forest cover types (5): Sugar Maple-Basswood (Society of American Foresters Type 26); Yellow-Poplar-White Oak-Northern Red Oak (Type 59); Beech-Sugar Maple (Type 60); and River Birch-Sycamore (Type 56). Commonly associated trees include basswood (Tilia spp.),
black cherry (Prunus serotina),
beech (Fagus grandifolia),
black walnut (Juglans nigra),
elm (Ulmus spp.),
hemlock (Tsuga canadensis),
hickory (Carya spp.),
Oak (Quercus spp.),
red maple (Acer rubrum),
sugar maple (A. saccharum),
yellow-poplar (Liriodendron tulipifera),
white ash (Fraxinus americana),
and yellow birch (Betula alleghaniensis).
In the northeast part of its range, it is often found with sweet birch (Betula lenta)
and in the northern part of its range it is occasionally found with white pine (Pinus strobus)
(4,15). Forest stands seldom contain more than an occasional butternut tree, although in local areas it may be abundant. In the past, West Virginia, Wisconsin, Indiana, and Tennessee have been the leading producers of butternut timber.
