Both of these rules provide an estimate of the board-foot content of a tree based on tree-trunk diameter breast high and merchantable tree height (discussed later). Merchantable height measurements are rounded to the nearest half-log. In the United States, the most common measure of lumber volume is the board foot, defined as a piece of wood containing 144 cubic inches. Trunks are divided into segments for volume calculations.
Bulletin of the Eastern Native Tree Society, Vol. Any objection to this equation rests primarily with the subjective nature of F1 and F2. 65 While measuring or estimating the height of a tree one should be very careful not to obtain uncertain values.
The simplest method to achieve this is to model the entire trunk with one application of a solid. With a couple of measurements taken from the tree the Doyle Scale will give us the tree’s volume. The length of these segments is set in the Trunk Segment Length for Volume Calculations, in m parameter. 2007.
This remark is even more valid when determining the volume of a tree. If you have problems with SORTIE crashing, try verifying that this behavior is the problem by removing it from the run and trying again. endobj 73 When using these tables, it is important to remember that only that portion of the trunk that will produce a useable product should be measured. 34 Similarly a model of overall trunk volume could potentially be predicted by using height, girth above basal flare, and the percent cylinder occupation for that species and age class.

Leverett, Robert T., Blozan, Will, and Beluzo, Gary A. published charts due to rounding. Leverett, Robert T. 2007. Tree calipers, Biltmore sticks, and tree-diameter tapes can be purchased through forestry equipment supply companies. When marketing timber stumpage, however, the choice of volume rule is less critical. 38 Given the general form changes from the base to top of the tree and the pattern of change in form factor over time, a predictive model was developed and applied to a variety of trees in New England where volume estimates were made based upon measurements tree height, girth at breast height, girth at root flair, and assigned values for form factor (taper), and a flare factor. Merchantable height is the height of the tree (or the length of its trunk) up to which a particular product may be obtained, usually minus a one-foot stump height. 12
When referring to the volume of a tree (expressed in m³) often only the volume of the trunk is meant, as this is most often the only volume that can be calculated with a sufficient degree of certainty. <> 71 Ground-based measurements are obtained by the use of a monocular w/reticle, laser rangefinder, and a clinometer.
