Growth Along the Stems of Full-Crowned Douglas-Fir Trees After Pruning to Specified Heights
Abstract:Twenty trees from 22 to 55 feet tall were pruned to 0, 1/3, ½, and 2/3 of their total height. Diameter measurements after one and two years at several points along the bole showed that 1/3 removal affected growth and form little or not at all. Volume growth was reduced by heavier removals but was so distributed that a more nearly cylindrical bole resulted. Height growth was reduced by the 2/3 pruning, but insignificantly by lesser removals.
