The Bowmont Norway Spruce Thinning Experiment 19301974
G. J. HAMILTON, Forestry Commission
Various effects of four different thinning treatments, after a period of 44 years, are outlined and discussed. In particular, there was found to be no significant difference between C, D, and LC grades in total volume production. The D grade thinning is shown to be the most favourable from an economic viewpoint.
