Abstract
Commercial thinning or density management treatments would be applied to dense and even-aged stands dominated by Douglas-fir. The objective would be reduction of relative stand densities. GFMA stands would be thinned from below, removing primarily suppressed and intermediate trees, though removal of some co-dominant and dominant trees would be anticipated. Thinning would be designed to achieve a Relative Density Index (RDI) of approximately 0.35-0.45, to maximize growth of the remaining trees.The primary objective of density management in Riparian Reserves would be to accelerate the development of late-successional forest and habitat characteristics. Also includes some road construction and renovation.
