A system of equations was used to produce compatible outside-bark stem taper and total tree volume equations for loblolly pine (Pinus taeda L.) plantations in southeastern Arkansas. Paired height diameter stem measurements were obtained from trees located in one 45-year-old unthinned plantation. After fitting and integrating the stem taper equation to total tree height, an individual tree constant form factor volume equation was obtained. The stem taper equation can also be integrated to any merchantable height to obtain merchantable volume. To see how the constant form factor volume equation predicts outside bark volume for trees vastly different than those used in model fitting, trees were harvested from a 17-yearold loblolly pine plantation in southeastern Arkansas. Predictions from the volume equation developed during this research were compared to three other commonly used volume equations. Validation results showed the current constant form factor equation produced the best predictions.
