Modeling alternative forest management scenarios across landscapes in the Pacific Northwest
- 1. Modeling alternative forest management scenarios across landscapes in the Pacific Northwest Matthew Goslin Mike Mertens Ecotrust -- Portland, OR The Forestry 2100 project
- 4. Forestry 2100 Pilot Study Area
- 5. Forest Land Ownership 250,000 ac 162,000 ac 706,000 ac 513,000 ac
- 6. Analytical Approach Map current vegetation Model development of individual plots Harvest Scheduler / Landscape Model Growth & Yield Model Most Similar Neighbor Imputation Projected harvest and standing volumes, age classes and forest structure across landscape by scenario Forest Inventory Sample Plots Compare scenarios
- 7. Sample Plot Distribution from USFS Forest Inventory Analysis Program
- 9. Imputed Stand Ages from MSN classification
- 10. Imputed vs. Observed Species Distribution: Sitka Spruce
- 11. Imputed vs. Observed Species Distribution: Noble Fir
- 12. Imputed vs. Observed Species Distribution: Bigleaf Maple
- 13. Projecting Future Conditions – Plot / Stand: Forest Vegetation Simulator (FVS) Harvest Scheduler / Landscape Model Growth & Yield Model Projected harvest and standing volumes, age classes and forest structure across landscape by scenario Tree growth Tree regeneration Forest Inventory Sample Plots Tree mortality Natural Processes Management Prescriptions Timing of Harvests Retention at Harvest Planting
- 14. Sample Stand Development Modeled by FVS: Basal Area, Tree Density and Mean Diameter Sample stand 11512: High density, high site index Douglas-fir dominated stand 5 years old at beginning of simulation
- 19. Modeled Sample Stand 11512: Private Industrial – “Business as Usual” Prescription Basal area by species Standing and harvested volume
- 20. Modeled Sample Stand 11512: Private Industrial – Alternative Prescription 1 (85% of area) Basal area by species Standing and harvested volume
- 21. Modeled Sample Stand 11512: Private Industrial – Alternative Prescription 2 (15% of area) Basal area by species Standing and harvested volume
- 24. Projecting Future Conditions – Landscape Harvest Scheduler / Landscape Model Growth & Yield Model Projected harvest and standing volumes, age classes and forest structure across landscape by scenario Even flow objective Adjacency constraints Overlay landscape with ownership bounds and management intent (GIS) Allocate prescriptions to stands Forest Inventory Sample Plots
