Abstract
  • Young western hemlock stands in the Coast Range of Oregon will contribute to the commercial timber supply of the region in the future, the extent of the contribution depending on environmental and cultural factors. The relative diameter and volume growth of crop-trees in the stands will be increased substantially by precommercial thinning. Heavy precommercial thinning in fully stocked stands will bring individual crop-trees to a commercial size more rapidly than those in lightly thinned or unthinned stands. Key words: precommercial thinning, western hemlock, Tsuga heterophylla, silvicultural practices, stand density, tree mortality, stand growth rates, Oregon Coast Range forests, thinning impacts, site factors.
