Book excerpt: Excerpt from Levels-of-Growing-Stock Study in Thinned Western Larch Pole Stands in Eastern Oregon In terms of timber management, the primary factor influencing the residual stocking level is the forester's estimate of the minimum size tree that will be merchantable in the future. The larger the trees must be to support a commercial thinning, the fewer trees should be left after precommercial thinning; and conversely, if smaller trees are merchantable, the residual stocking should be higher. Western larch (larix occidentalis Nutt.) is a valuable seral species in the mixed conifer forests of north eastern Oregon because of its fast growth rate and desirable wood proper ties. Even-aged larch stands generally become established following fire or other forest disturbances. These stands are often heavily overstocked as seedlings. Stand density control by thinning is an essential part of the management of young larch stands. Because of the shade intolerance of larch, tree crowns in unthinned stands are reduced in size resulting in a decrease in rates of diameter and height growth as early as 9 years of age (schmidt The increasing utilization of larch and other species and the associated intensification of forest management raises questions regarding suitable stocking level regimes for managed larch stands.
