Levels of Growing Stock Demonstration Area

Purpose

This study includes three levels of growing stock and one control plot. One plot is thinned to a constant basal area about every 10 yrs..; one plot allows the basal area to increase at each periodic thinning; and one plot follows the Britining guidelines

An Experiment to Analyze Prebunching With a Low Investment Skyline Yarder as and Economical Approach to Thinning Young-growth Pacific Northwest Timber Stands

Purpose

The experiment will use each skyline road as an experimental unit. Ten units will be laid out, each 1,00 ft. by 250 ft. wide. Four units will be assigned as silvicultural control units. Two will be assigned as thinning control units and will be logged
