  3. What was needed? A strategic assessment of western forest biomass! How much? Where? What kind? Who owns it? Treatment opportunities? Potential yields? Small diameter utilization potential? Costs ?

  4. The West – A BIG Place 129.6 million acres

  5. Forest Inventory and Analysis Data Nation’s Forest Census 75 Year History Comprehensive and Geo-referenced Sampling Frame Nationally Consistent Sampling Protocols 5 Year Roll Up of National Statistics in RPA • Used combination of • periodical state and • annualized inventories • Extrapolation and data • synthesis • - Special analysis • Phase I is remote sensing; 1 plot • for 100 ha • Phase II is ground sampling; 1 • plot for 2200 ha • Phase III is intensive plots; 1 • plot for 38,500 ha

  6. Totals (in millions): Timberland – 129.6 acres Biomass – 6855.0 dry tons

  7. Biomass Analysis Acres and Volumes by • Condition Class • Stand Prescription Treatments (Used Stand Density Index) • Utilization (>7-in stem volume; <7-in stem, limbs, and tops) • Accessible • Terrain • Road • USED 60% ACCESSIBILITY

  8. Condition Classes 1 – use prescribe fire 2 – some mechanical treatments 3 – mechanical treatments required Source: USFS Fire Sciences Laboratory

  9. SDI Approach to Biomass Yields • Stand Density Index approach is: • Science-based (species and locality differences are considered) • Allows for retention of some small trees as well as the removal of trees in all dbh classes (e.g. sustainability) • Provides a conservative and balanced stocking distribution over large areas • Doesn't require development of detailed prescriptions for large areas • Allows flexibility (Don’t know where trees actually are, so any management system can be accommodated at local scales)

  11. SDI Thinning

  12. Totals (in millions): Treatable timberland – 96.9 acres Biomass – 6447.4 dry tons Potential yield – 2154.0 dry tons

  13. Totals (in millions): Treatable Cond. 2&3– 66.9 acres Biomass – 4529.1 dry tons Potential yield – 1493.4 dry tons

  14. Totals (in millions): Treatable Cond. 3– 28.5 acres Biomass – 1791.1 dry tons Potential yield – 576.1 dry tons

  15. Small Diameter Utilization Potential Volume vs. number of trees!

  16. Small Diameter Utilization Potential • Results • 245 million bdt of merchantable products • Annual Removal of 8-51 million bdt • Twice as much as current mill capacity for • Total 101 million bdt of non-merchantable biomass • Some MDF, OSB, and pulp capacity • Little energy capacity Potential Yield by Owner Condition Class 3

  17. Range of Conditions

  18. A big job AHEAD! • Total removal volume from Class 2 and 3 is nearly 40 times the annual conventional removal volume • The forest types and terrain are highly variable • Potential products and markets are also variable • Operations have to match the treatment and forest conditions as well as the product options See entire report on www.fs.fed.us/research/pdf/Western_final.pdf

  19. New Biomass Analysis Tools • BioSum - PNW • Field Treatment Evaluator – FPL • Biomass Mapping Program – FIA & RSAC • Others
