Washington Forest Biomass Supply Assessment

A recently released report, Washington Forest Biomass Supply Assessment, characterizes forest biomass availability and sustainability on all forest land ownerships in that state. The study was designed to help ensure that Washington’s forest biomass-to-energy sector moves forward sustainably. The assessment had three major goals: (1) estimate the volume of forest biomass, stratified by landownership categories, forest ecosystem types, species and location (whether it was removed or retained on site), and develop a spatially explicit biomass database; (2) assess biomass availability based on various cost and price considerations, market prices and residual value to the landowner; and (3) provide public access to the biomass database through a web-based calculator tool.

The assessment was prepared for the Washington Department of Natural Resources by the University of Washington School of Environmental and Forest Sciences and TSS Consultants with financial support from the USDA Forest Service. The final report is available at http://www.dnr.wa.gov/Publications/em_finalreport_wash_forest_biomass_supply_assess.pdf. The biomass calculator is accessible at http://wabiomass.cfr.washington.edu/.
