Abstract

Seedlings were thinned to spacings of 6, 9, 12, 15, and 18 feet and measured periodically. Twenty-seven years later, height did not differ with spacing, but diameters increased while basal areas and cubic volumes decreased as spacing widened. Simulation to age 100 years indicated that about the same board volume would be produced at 12-, 15-, and 18-foot spacings.
