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.
