Forests As Sources of Aviation Fuels: Analysis of Impact On Nutrient Budgets.

Biomass, carbon and nitrogen pools in soil (1 m depth) and tree components in 71 intensively managed Douglas-fir plantations in western Oregon, Washington, and British Columbia. The potential removal of N during harvesting was compared to total ecosystem pools of nutrients to determine the relative removals compared to the total ecosystem N pools to assign a risk rating to each potential harvest site. The evaluation was used as a basis for assigning relative risk to the potential use of the forests as sources of bioenergy in the Pacific Northwest vs. traditional harvests for timber.
