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 seasons growth. Author
