Summaries from 49 published articles on tree volume and taper equations are presented for 39 tree species found in California, Oregon, Washington, British Columbia, southeast Alaska, Idaho, and western Montana. The summaries are organized by species and then by type of equation (volume or taper). Each summary describes the types of dependent variables predicted by the equations and the geographic location, number of trees, range in DBH, and range in total height for trees in the sample used to develop the equations.

Excerpt from Comprehensive Tree Volume Equations for Major Species of New Mexico and Arizona, Vol. 1: Results and Methodology Comprehensive tree volume equations and the methodology used to derive them are presented for the major tree species of New Mexico and Arizona. With these equations, the following gross and net volume types can be computed for both unforked and forked trees: total stem cubic foot volume; merchantable cubic foot volume to any top diameter between 3 and 8 inches, inside bark; International -inch board foot volume to a 6-inch top, inside bark; and Scribner board foot volume to a 6-inch top, inside bark. These equations were developed in such a manner as to eliminate many of the problems of consistency, compatibility, reliability, and flexibility associated with previous sets Of volume equations. This approach also allows the user to divide total stem cubic foot volume into top volume, merchantable volume, and stump volume. This last feature is useful for predicting the level of residues after harvesting to various top diameters.
