Volume Tables For Pacific Northwest Trees

Compiled by F. A. Johnson

Pacific Northwest Forest and Range Experiment Station

This collection of volume tables has three purposes. One is to facilitate

:omparisons among tables, another is to release some unpublished tables

for general use, and the third is to preserve certain tables for their reference value.

Many of the tables are relatively unknown, while others have been widely

distributed and are familiar forestry tools. Not all tables given here are

necessarily recommended; a few would have been excluded if past use had

not made them indispensable for re-examinations of old studies and surveys.

Specifications for each table are presented as uniformly and as completely

as possible in the table headings. These specifications should prove helpful

in judging the adequacy of the tables for a particular use.

Although an attempt was made to include only tables which are regional

in scope,^ some tables for restricted areas were used when regional tables

were not available. A few tables developed outside the region were also

included to fill conspicuous gaps.

The abbreviation d.i.b. refers to diameter inside bark, and d.b.h. refers

to diameter outside bark at breast height imless otherwise specified. Bark

is excluded from the listed volumes in all tables except table 1.

^Attentiort is directed to two notable omissions: (1) the form class volume tables prepared by the firm of

¡î^iason, Bruce & Girard, and (2) the site quality tables developed by D. G. McKeever of the Weyerhaeuser Timber

Company. These two sets of tables, available elsewhere, are important contributions to forest mensuration

in the Pacific Northwest.
