	Department: Plant Pathology & Tahoe Environmental Research Center E-mail: pemaloney@ucdavis.edu Phone: 775 881 7560 ext. 7473 Research: Forest, disease, and conservation biology of five-needled white pine species in California and Nevada. Current focus is to understand the response of forest trees to environmental change by evaluating population dynamics, genetic structure, and adaptive traits (e.g., disease resistance, drought adaptation/water-use efficiency, phenology, etc.). I also focus on the conservation of white pine species via cone collections and seed-banking.

	Department: Plant Pathology E-mail: dmrizzo@ucdavis.edu Phone: 530-754-9255 Web Site: Click Here Research: Ecology and management of forest tree diseases. Current focus is on Sudden Oak Death (SOD)in CA coastal forests and diseases of conifers in the the Sierra Nevada Mountains and other interior mountain ranges. These projects are also linked to forest management including the role of fire and forest thinning.

Yana Valachovic
	E-mail: yvala@ucdavis.edu Research: As Forest Advisor, I work to address the needs of forest landowners in the fields of forest management and ecology through research, technical consultations, short-courses and regional conferences. My program emphasis is on redwood and Douglas-fir silviculture, forest policy, education, incentives to improve forest stewardship, watershed management, conservation biology, fuels management and insect and disease management. My research projects have included the early detection and treatment for areas infested with the plant disease known as Sudden Oak Death, surface fuels evaluations, assessment of the 2003 Canoe fire severity, assessment of large woody debris in streams, and assessment of coarse woody debris in forests. I offer frequent workshops and have covered subjects such as forest management, carbon sequestration, biomass opportunities, planning, advanced road restoration, non-timber forest products, tree planting, fuel hazard reduction, Sudden Oak Death awareness and the annual Forestry Institute for Teachers.
