Abstract:

Basal area, as it will appear five years hence, can be predicted by the point center extension technique for southern pine stands which contain from 40 to 130 square feet of basal area per acre. Trees can easily be separated into their product classifications and allowances can be made for in growth and product growth. Basal area by products can be converted into volumes by products, and thus values and yields can be determined. With dollar yields per acre per year and percent yields known, an economic analysis and comparison of individual stands will help establish priorities for future stand treatment. The principal advantage of point sampling is that it eliminates tree and plot diameters. This technique also eliminates these diameters and herein lies its efficiency of application. It is not uncommon for a two-man crew to tally a point in five minutes. The calculations are very simple and the time required is almost negligible. In fact, the whole calculation can be done in the field. The details of this technique may need refinement for varying conditions but the principles involved are sound when used in the manner and for the purposes recommended.
