Results after 20 years from a western larch levels-of-growing-stock study.

Abstract

The 20-year growth response from a levels-of-growing-stock study in an even-aged western larch stand in eastern Oregon, first thinned at age 33, showed that trees growing at low stand densities grew more rapidly in diameter than trees in high-density plots. Height growth was relatively uniform among density levels. Both basal-area and total cubic-volume increment increased as stand density increased. Despite the large reduction in volume increment at the low densities, most of the wood is concentrated on a few, fast-growing trees that can reach usable size sooner than slow-growing trees in high-density plots.
