Long-term precommercial thinning effects on Larix occidentalis (western larch) tree and stand characteristics

Publications Posted on: June 23, 2017
Precommercial thinning (PCT) is used to increase tree size and shorten harvest rotation time. Short-term results from PCT studies often show a trade-off between individual-tree growth and net stand yield, while longer-term effects of PCT on tree growth and stand yield are less well documented.

Early forest thinning changes aboveground carbon distribution among pools, but not total amount

Publications Posted on: January 12, 2017
Mounting concerns about global climate change have increased interest in the potential to use common forest management practices, such as forest density management with thinning, in climate change mitigation and adaptation efforts. Long-term effects of forest density management on total aboveground C are not well understood, especially for precommercial thinning (PCT) implemented very early in stand development.

Forest thinning and subsequent bark beetle-caused mortality in Northeastern California

Publications Posted on: November 08, 2010
The Warner Mountains of northeastern California on the Modoc National Forest experienced a high incidence of tree mortality (2001-2007) that was associated with drought and bark beetle (Coleoptera: Curculionidae, Scolytinae) attack. Various silvicultural thinning treatments were implemented prior to this period of tree mortality to reduce stand density and increase residual tree growth and vigor.
