摘要

The 15-year growth response from a levels-of-growing-stock study in an even-aged western larch (Larix occidentalis) stand, first thinned from above and below at age 55, was measured in northeastern Oregon. Basal area and volume growth increased with stand density for both thinning methods, whereas diameter growth decreased. Attacks of the larch casebearer (Colephora laricella) for about three years reduced height growth because of top dieback but diameter and volume growth were not severely impacted. Thinning from above reduced net volume growth because of considerable mortality caused by windthrow and snow or ice damage, although surviving trees responded well to increased growing space.
