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
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
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)

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.
