Effects of Timber Harvesting on Groundwater Level and Slope Stability in Deeply Weathered Material

Purpose

Effects of timber harvest on groundwater level and slope stability in deeply weathered material. Areas will be clear-cut when sufficient data on the water table and soil creep has been collected. The researchers anticipate about a 5 yr. period to develo

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
