In the first paper, the procedures are developed to compute tree volume equations from field measurements taken with a Barr and Stroud optical dendrometer. The computer programs used to perform all of the calculations are briefly described. The volume equations developed for young growth Sierra redwood are also reported, together with a discussion of the validity of these equations.

In the second paper, tree volume tables are given for young growth Sierra redwood based upon measurements taken at Mountain Home State Forest. Standard and local volume tables are given for cubic feet and Scribner board feet, together with the 95 per cent confidence intervals for the volumes in these tables. The standard table for cubic feet is based upon total height while for Scribner board feet tables are given for both merchantable height (6-inch top) and total height.
