DescriptionLight commercial thinning in 100-year-old, well-stocked, mixed stands of western hemlock and Sitka spruce at Cascade Head Experimental Forest produced no consistent growth and yield responses related to thinning intensity. Mortality for all causes except windfall was generally less for thinned stands than for unthinned stands. Losses from windfall appear to be related more to location than to thinning.
