A Program for the Trunk Formula Method of Tree Appraisal    (View PDF)

George E. Fitzpatrick

Abstract: A program is presented that computes tree appraisal by the trunk formula method as presented in the Guide for Plant Appraisal, 8th edition (2). It is written in the RPN language and requires 62 lines of memory. It is designed for hand-held, battery-operated calculators that have a minimum of 10 storage registers and the capability of conditional branching in their programming format. Use of this program can reduce the problem of computational error and possible lack of precision in determining tree value by the trunk formula method and significantly reduces the time required for the calculations.
