Modeling Crown Development and Wood Quality

Abstract

Trees grown in the open with little competition have a larger, more vigorous crown, slower rate of crown recession, larger diameter and greater taper than trees grown in a dense stand. The open-grown trees will also have branches that are long-lived and produce large knots. The growth rate of the trees will also affect lumber yield. This article briefly describes the use of computer models to predict both growth, and characteristics of stem and crown. The computerized trees can then be processed in a virtual sawmill to evaluate the yield, grade and market value of the lumber. Managers can use the models to determine silvicultural options.
