DescriptionKnowing the thickness of bark along the stem of a tree is critical to accurately estimate residue and, more importantly, estimate the volume of solid wood available. Determining the volume or weight of bark for a log is important because bark and wood mass are typically separated while processing logs, and accurate determination of volume is problematic. Bark thickness is known to vary with species, tree diameter, and location along the stem. This paper examines the bark thicknesses of four Appalachian hardwoods: red oak (Quercus rubra), white oak (Quercus alba), yellow-poplar (Liriodendron tulipifera), and sugar maple (Acer saccharum). Using bark thickness measurements from multiple sites, average bark thickness by stem diameter and sample height location were determined. In addition, models were developed that predict bark thickness based on measured diameter outside the bark.
