Equations for Estimating Bark Volume and Thickness of Commercial Trees in British Columbia

Abstract

Volume and thickness of bark were studied for 32 species groups of British Columbia. Over 32,000 trees constituted the data base to derive bark volume equations. Because of its simplicity and good predictive power, the equation of V b = a'HT b DBH c BT d is recommended for bark volume prediction. The possibility to develop bark taper equations and to estimate bark thickness at any given height above breast height were also investigated.
