This Canadian study analyzes the effect forest management has on net carbon sequestration, including, as separate entities, net carbon storage in litter, soils, wood products and landfills. Five forest management activities are analyzed using two forest types (Nova Scotia Red Spruce and Coastal Douglas Fir) as examples. The following activities are analyzed: pre-commercial thinning; commercial thinning for pulp; commercial thinning for pulp and lumber; increasing the rotation length; and increasing the amount of slash used for biofuel.
