Response of Western Larch to Changes in Stand Density and Structure

摘要

The 5-year growth response of a 55-year-old, even-aged western larch stand thinned from above and from below to a wide range of stocking levels was measured in eastern Oregon. Both basal area and volume growth increased as stand density increased for both thinning methods. Diameter growth increased moderately in response to decreasing stand density when thinned from above and from below, but height growth was not affected by thinning intensity or method.
