Title
Decay in standing trees of the Pacific Northwest, 1982-1992
Abstract
The primary objective of this study is to predict the volume of the tree bole that is left on the site during a harvest operation. This data is needed to predict the amount of woody detritus left on a site after harvest. This in turn is used to predict how carbon stores change during succession.
