Programs/Research Collaborations:

Forest Health Specialist, Forestry and Natural Resources Extension
In collaboration with County Forestry Extension Agents, we produce Extension and Continuing Education forest health programming and publications, including an electronic series of extension circulars’ (EC) and extension manuals (EM), a book entitled, “Managing Insect and Diseases of Oregon Conifers” (funded by Oregon Forest Resources Institute (OFRI), and development of a volunteer program called, “Pest Scene Investigators” (also initiated with funds from OFRI).  Extension Forest Health Programs are meant to serve the needs of Oregonians, with a focus on forest landowners.

Director, Swiss Needle Cast Cooperative, (http://sncc.forestry.oregonstate.edu/)
Damage caused by Swiss needle cast, a native foliage disease (caused by the fungus Phaeocryptopus gaeumannii) that affects Douglas-fir along the coast, has made it imperative that effective monitoring and new research be conducted to learn practical methods of disease detection and management to maintain the health and productivity of Douglas-fir plantations. The Swiss Needle Cast Cooperative (SNCC) was established in January 1997. The focus of SNCC is Swiss needle cast research, monitoring, and outreach to benefit forest land owners in the Pacific Northwest.
