A Technique for Quantifying Forest Stands for Management Evaluations.
Abstract
In this study, a system for describing the three-dimensional geometry of trees and stands is presented. The system consists of two survey instruments, a theodolite and transit, and basic triangulation principles. A spotting laser has recently been added to the system to facilitate the spotting of the tree nodes to be surveyed. Measurements were made of 16 Douglas-fir trees within a fertilized stand and an unfertilized stand in the A. E. Thompson Research Area, near Seattle, Washington, and two shortleaf pines and a hickory at the Texarkana Reservoir, near Texarkana, Texas. A measure of wood productivity (or growth) for the Douglas firs was made by sampling the trees before (April 1970) the start of and after (October 1970) a season's growth. (Author)
