Excerpt from Volume Tables and Point-Sampling Factors for Ponderosa Pine in the Front Range of Colorado Diameter at breast height - Measured to the nearest inch, outside the bark, at feet above ground level, on the uphill side of the tree. Full-inch diameter classes with class midpoints at the -inch marks, are used In the tables. Total height - Measured, in whole feet to the near est foot, from ground level on the uphill side of the tree upward to the tip. Trees forked below utilization limits described below, stag-topped, or severely deformed were not included in the sample. The midpoints of total height classes in the tables are multiples of 10 feet. Scaling diameter of logs. - Average diameter inside bark to nearest inch, measured at the small end of logs or half-logs. Minimum top diameters for merchantable volumes. Minimum top diameter inside bark for computation of merchantable cubic-foot volume was 4 inches. For board-foot volume, a minimum top diameter inside bark of 6 inches was used to conform to local practice. Logs with a scaling diameter smaller than inches usually were not included in saw-log volume. A few logs with smaller scaling diameters were included to satisfy the 4-foot rule described below.
