Advancements in Environmental Research and Forest Management Techniques

The 2005 PNW-FIA Client Meeting in Troutdale, OR, gathered full-time and part-time scientists to discuss critical advancements in environmental research and forest management. The team, which includes renowned experts like Dave Azuma and Tara Barrett, focuses on policy-relevant, hypothesis-driven research. Highlights include innovative inventory techniques, collaborative studies on riparian forests, and the impact of invasive species. The meeting also addressed significant findings related to tree mortality in California and optimization of biomass plant siting to enhance forest management and fire hazard reduction.

  1. 2004 HighlightsEnvironmental Analysis & Research Team (EAR) 2005 PNW-FIA Client Meeting 15 March 2005 Troutdale, OR

  2. Who we are • Full-time scientists • Dave Azuma • Tara Barrett • Jeremy Fried • Demetrios Gatziolis • Andy Gray • Part-time scientists • Vicente Monleon (SCEP) • Todd Schroeder (Ph.D. candidate)

  3. Our Mission • Policy relevant, hypothesis based, research and development • Inventory techniques research • Design and guidance on inventory implementation & QA • State liasons (Andy, Dave, Jeremy) • Analytic consultations

  4. 50 (23 CA, 27 OR/WA) studies/collaborations • ODF: LIDAR model for crowns & terrain • ODF: Riparian stratification & plot design • OSU: Forest canopy structure sampling • OSU: Carbon dynamics uncertainty modeling • Sonoma State: P. Ramorum host map accuracy • UWisc: Wildland urban interface mapping • UCB: Historic Weiselander plots and maps for CA • UMontana: Classifying stand structure via SVS • S&PF: Sudden oak death remeasurement • National Fire Plan: Post-fire remeasurement • PNW: Community composition & gradient analysis • PNW/JFSP: GNNfire fuel maps • PNW/R3: FIA BioSum ORCA/AZNM + Biosummatic

  5. Juniper forest expanded from 436 thousand acres in 1936 to 3+ million acres Of the 3 million acres of juniper savanna, 1 million have more than 25 trees per acre Even if only half of savanna lands show increases in juniper density, Oregon will have over 5 million acres of juniper forest in 20 years Western juniper – Dave Azuma

  6. John Day riparian pilot – Vicente Monleon • Assess efficiency • Of two plot shapes (circular vs. rectangular) • Of two plot sizes (one vs. both sides of the stream). • Develop estimators of population attributes when sample locations are obtained from a GIS-based stream network • Compare characteristics of riparian forests vs. upland forest in the John Day watershed. • Evaluate stability of indicators of vegetation degradation as sampling protocols vary (with EPA)

  7. Invasives in OR – Andy Gray Proportion of P3 plots with 1 or more nonnative plants by ecoregion (overall=71%)

  8. Proportion of species that are nonnative

  9. Barrett, Tara M. Pre-epidemic mortality rates for common Phytophthora ramorum host tree species in California. (In press, proceedings of the Sudden Oak Death Science Symposium II) • SOD mortality first found 1995 in tanoaks. • Average annual mortality 1981-84 to 1991-94 of host trees: • 0.43 +/- 0.09 percent (natural) • 1.02 +/- 0.13 percent (total) • In 14 California counties that are under quarantine, volume of 9 host species increased an estimated 4 to 28 percent between 1981-84 and 1991-94. • Best guess of longer term trend: hardwood timberland host species (bigleaf maple, California black oak, California laurel, Pacific madrone, and tanoak) had substantial volume/biomass increases from the late 1960s to the early 1990s.
