Abstract : The U. S. Army Engineer Waterways Experiment Station has developed and evaluated a nondestructive system for describing the three-dimensional geometry of trees and stands. Tree or stand productivity was determined by dimensioning (i.e. measuring) the trees (or stands) before the start of a growing season and again after the growing season was completed. A measure of productivity was established by calculating the change or increase in tree height, stem and branch diameters, and wood volumes for each tree. This system has demonstrated that significant changes changes wood volumesfor each tree. This system has demonstrated that significant changes in tree productivity during one season's growth can be detected between untreated stands and ones subjected to fertilizer treatments, thus making it an invaluable tool for management of forest stands.
