  2. The Data 78 PermanentPlotsBeginning1913Ten YearMeasurementCycle

  3. Data Contains

  4. Forest Vegetation SimulatorFVS The data can be easily converted to FVS format

  5. Learn From the Past To Understand the Future

  6. Question Climate Growth VS

  7. Can We Identify Growth and Climate? • Not new Fire history Dendroclimatology • Time consuming FVS Scale Factor

  8. FVS Scale FactorAl Stage and Bill Wykoff Assumptions Tree growth is an integrator of site Growth is based on a site potential • Method to quantify site variability • Growth multiplier • Adjust FVS base equations

  9. FVS Scale Factor • Model equations are standardized Slope, aspect, elevation, habitat type, tree density, and tree diameter • Not standardized soil characteristics climate • 10-year diameter increment

  10. FVS Scale factor attenuation occurs over time to the adjustment of the large-tree diameter growth equation. Growing faster Baseline Growing slower

  11. Priest River Experimental ForestEstablished 1911 Priest Lake R.D.

  12. Eighteen Permanent Plots Weather Station

  13. Daily WeatherSince 1911

  14. Forest Inventory and AnalysisMeasured 2011

  15. Other Opportunities and Needs • The permanent plots have never been summarized. • Budget is limiting future measurements? • What would be useful information from long-term data? • Are there other complimentary data?
