  1. Applying Forest simulation modeling to test the impact of climatic change on selected ecosystems at two mountain transects in Nevada Mike Hay, Franco Biondi, Jimmie Chew, Robin Tausch

  2. Presentation Outline • Purpose • Simulation model • Data • Directions/Work to be done This material is based upon work supported by the National Science Foundation under Cooperative Agreement No. EPS-0814372

  3. Purpose Main objective: insert climate into models used by resource managers This material is based upon work supported by the National Science Foundation under Cooperative Agreement No. EPS-0814372

  4. Vegetation depends on succession, disturbance, and climate (plus humans) Grazing 2 1 3 6 P-J Expansion Fire Suppression Altered Fire Regime 5 4 Climate Change This material is based upon work supported by the National Science Foundation under Cooperative Agreement No. EPS-0814372

  5. How do we combine records (instrumental and proxy) with simulation models? Recent observations show a strong east-west gradient in wildfires across Lincoln County (Dilts et al. 2009) However, long-term fire history data show that this gradient may be a recent phenomenon (Biondi et al. 2011)

  6. SIMPPLLE is an acronym for: Jimmie Chew and Kirk Moeller, USFS Rocky Mountain Research Station, Missoula MT

  7. Simulation model • http://www.fs.fed.us/rm/missoula/4151/SIMPPLLE/index.html This material is based upon work supported by the National Science Foundation under Cooperative Agreement No. EPS-0814372

  8. SIMPPLLE was developed as a management tool to: • HANDLE DISTURBANCE PROCESSES AS STOCHASTIC EVENTS • CAPTURE THE INTERACTION BETWEEN VEGETATION PATTERNS AND DISTURBANCE PROCESSES • PROVIDE FOR A QUANTIFICATION OF THE RANGE OF VARIABILITY FOR BOTH VEGETATION CONDITIONS AND DISTURBANCE PROCESSES • IMPROVE OUR ABILITY TO IDENTIFY DESIRED FUTURE CONDITIONS OF BOTH VEGETATION CONDITIONS AND LEVELS OF DISTURBANCE PROCESSES • INTEGRATE KNOWLEDGE FROM RESEARCH STUDIES, FINE SCALE MODELS AND EXPERT OPINION
