Tree Taper Model Volume Equations: IV. Tree Volume Equations for Major California Conifers

Abstract

Equations and tables are given to estimate total tree board foot and cubic foot volume for eight major California conifer species. Using taper equations developed in another study, log dimensions were estimated for the trees used in the stem taper study; then coefficients for whole-tree volume equations were fitted to the resulting set. This produced Scribner and International ¼-inch board volume, and cubic volume equations for the eight important commercial conifer species in California. For board-foot volumes, separate equations are given for both total and merchantable heights to various merchantable tops.
