Bitternut hickory, though present throughout the eastern forest, does not grow in sufficient numbers to be included as a titled species in the Society of American Foresters forest cover types (8), but it is mentioned as an associated species in six types.

In addition to the species named in the cover types, bitternut hickory grows with various oaks (Quercus spp.) in the northern region. In the southern part of Quebec, there is a sugar maple-bitternut hickory subtype that is restricted to deep soils. Trees associated with it inclu
