Predicting Board-Foot Tree Volume from Stump Diameter for Eight Hard-wood Species in Ohio

Abstract

Regression equations were developed to predict volume table values for merchantable gross volume from stump diameter for eight species of hardwood trees in south-central Ohio. Mesavage and Girard's volume tables were used to develop equations for both the Doyle and International lA log rules. Data for the study were collected in Scioto Co., Ohio. Regression equations were weighted by the inverse of estimated variances. The range in R2 was from 0.82 to 0.96. Both equations and tables are presented for each species and for combined equations.
