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.

Potential units for commercial thinning have been identified in the Upper Middle Fork Coquille River Watershed Analysis Unit in T. 29 S., R. 8 W., Section 29; T. 29 S., R. 9 W., Section 13; and T. 30 S., R. 9 W., Sections 13 and 23. Other units were identified in the Middle South Umpqua River/Rice Creek Watershed in T. 29 S., R. 6 W., Sections 27, 33 and 35; T. 29 S., R. 7 W., Sections 25 and 35 and the Lower Cow Creek Watershed in T. 30 S., R. 6 W., Sections 3 and 9.
