Forest Health In Oregon: State of the State 2018 was held Feb 28, March 1, 2018. See the presentations posted at: http://blogs.oregonstate.edu/foresthealth/

Forestry and Natural Resources Extension:I serve those interested in forest and tree health in Oregon with a focus on County Forestry Extension Agents and their clientele, forestry professionals, and small woodland owners and tree farmers.

Swiss Needle Cast Cooperative:

I am Director of the Swiss Needle Cast Cooperative (http://sncc.forestry.oregonstate.edu/). Swiss needle cast is foliage disease that is specific to Douglas-fir caused by the Ascomycete fungus Phaeocryptopus gaeumannii. The disease was first described in Europe, but the fungus is native to western North America. The cooperative is a collaboration of industry, agencies, extension and academia which is focused on research, monitoring and outreach concerning impacts, epidemiology, spread and intensification of this disease.

PI. Permanent Vegetation Plots:

Collaborating with David Bell, PNW Research Station. Rob Pabst, OSU FRA manages field crews, plot measurement, and data storage. H.J. Andrews Experimental Forest, Long-term research network (LTER), and regional collaborators. National Science Foundation, HJA Long term ecological research network 7 co-PI. We manage a permanent plot network to measure vegetation and tree dynamics across 145 installations in western Washington and NW Oregon, visited every 5-6 years. Some plots have been measured for over 100 years, and include USFS early plot installations. 45 installations occur on the HJA. Provides data for assessing long term forest health and mortality.
