Based upon our data and the published literature (Lorimer 1993; Walters and McCarthy 1997), we believe the low diversity of "small" trees is due in part to the relatively high fecundity and survivorship of Acer saccharum, and low recruitment by Quercus and Carya species (Table 1, "small" class; Table 2).
Hickory sold as Lumber and veneer--the so-called true hickories--comes from a variety of Carya species, usually Carya ovata, Carya glabra, Carya tomentosa, and Carya laciniosa.
The overstory here has a very high proportion of Quercus and Carya species.
A visual survey of the overstory confirms the present dominance of Quercus and Carya species and the growing dominance of Acer saccharum.
With time and mortality of maturing Quercus and Carya species, the Quercus--Carya association may be dominated by shade-tolerant species.
