Effect of method of thinning on wood production in a red pine plantation

Abstract

The total production of main-stem wood volume by a red pine plantation in New Hampshire did not differ during a 12 yr period between (a) low, (b) crown, and (c) selection thinning when the same amount of basal area was reserved in two successive thinnings. The reservation of larger trees in low and crown thinning improved production of board-foot volume and such trees suffered less mortality from annosus root disease.
