Abstract Volume equations used in forest survey in the northeastern United States were evaluated using data collected as part of utilization studies. Results are presented for both cubic foot and board foot equations for 16 species groups. Existing cubic foot equations were found to be satisfactory while the board foot equations generally produced significantly large underestimates. New board foot equations that include a measure of tree form were derived. North. J. Appl. For. 6(1):27-31, March 1989.
