Comparison of Formulas for Estimating Volumes of Butt Logs of Appalachian Hardwoods
A database comprising measurements of over 700 trees and logs of Appalachian hardwoods was used to compare the performance of five formulas (Newton, Huber, Smalian, Bruce, and that of the centroid method)for estimating the volumes of butt logs. In terms of bias and precision, the centroid method was clearly superior to all other methods. Bruce's formula performed better than Smalian's formula and is recommended for use when only the ends of butt logs are accessible for measuring diameter, as in log stacks. North. J. Appl. For. 13(1): 5-7.
