THE EFFECT OF VARIOUS THINNING GRADES ON THE GROWTHAND VOLUME PRODUCTION OF PINUS PINASTER

D. G.M. Donald

Abstract

Summary The results of an experiment using different thinning grades on Pinus pinaster in the Cape Midlands are described and briefly discussed. It is concluded that thinning, while unable to increase the total volume production of which a site is capable, can greatly affect the way in which that volume is produced. It is further concluded that the heavier grade of thinning is more profitable than the lighter grades.
