  1. Using FIA Data to Strategically Assess Fire Hazard and Management Opportunities in Montana and New Mexico • Charles E. Keegan III • The University of Montana

  2. Cooperators • The University of Montana • School of Forestry • BBER • PNW Research Station • RM Research Station (IWFIA)

  3. OBJECTIVES • Describe current forest conditions in Montana and New Mexico • Assess existing crown fire hazard • Evaluate effectiveness of fire hazard reduction treatments • Estimate treatment costs and revenue • Evaluate future treatment effectiveness

  4. METHODS FLOW CHART Current Forest/Stand Conditions (1) FVS FFE FIA Data Format Edit Current Fire Hazard (2) High & Mod. Hazard Stands FVS 30-yr Projection FFE Leave-Tree Stand Tables Apply Alternative Rx’s Cut-Tree Stand Tables Cost, Products & Value Model FFE Costs (Revenues)/Ac by Prescription (4) Fire Hazard 30 Years Post-Treatment (5) Fire Hazard Immediately Post-Treatment (3)

  5. Current Forest Conditions • Forest types & acreages • Tree density • Vertical stand structure • Species composition

  6. Forest Types of Greatest Concern • Ponderosa pine • Douglas-fir • Dry lower-elevation mixed-conifer Because: near persons & property, ecological changes due to fire suppression activities and past logging practices

  7. Ecological Problems • Increased density • Continuous structure of ladder fuels • Changed species composition

  8. Fire Hazard for PP, DF, & DLMC Forests Total for forest types = 9.3 million acres

  9. Proposed Treatments • Thin-from-below • focus on removing small trees • cut only trees dbh < 9” • burn/dispose of slash • Comprehensive • focus on future stand’s ecological condition • thin-from-below & remove slash • stand improvement cut • selection cut in mid- & upper canopy

  10. Comprehensive Treatment Product Removals • Sawlogs & Studlogs • 1000 cubic feet per acre • 9 - 20+” dbh Pulpwood • 300 cubic feet per acre • 5 - 8” dbh

  11. Crowning Index and Revenue Montana-Statewide

  12. Net revenue for comprehensive treatment of PP, DF, & DLMC - 1997-1999 markets

  13. New Mexico Forestland by Fire Hazard Total forestland = 16.7 million acres

  14. Fire Hazard for PP & DMC Forests in New Mexico Total for forest types = 4.0 million acres

  15. Average Crowning Index and Revenue Per Acre Across New Mexico
