Tim Whitesel

Educational Background: Ph.D., Biological Sciences, 1990, University of Rhode Island; M.S., Zoology, 1987, University of Rhode Island; B.A., Philosophy, 1985, State University of New York at Fredonia; B.S., Biology, 1983, State University of New York at Fredonia

From 1991-2001, Tim worked for the Oregon Department of Fish and Wildlife. In that capacity he has served as the program leader for native trout studies, the coordinator for endangered species activities, and as a supervisory biologist for studies on threatened and endangered salmon and steelhead. His work has focused on basic research with salmonids. Tim has designed and implemented studies of bull trout genetics, life history, habitat needs and limiting factors in eastern Oregon as well as projects to evaluate movements and habitat requirements of westslope cutthroat trout. He has coordinated activities for the state of Oregon that were associated with fish species listed, both federally and by the State of Oregon, as endangered or threatened. He has also designed, implemented and conducted projects to evaluate chinook salmon and steelhead trout compensation, supplementation, and recovery efforts. These programs focused on the use of hatcheries and revolved around traditional production projects, projects to supplement natural populations, and captive broodstock projects. Tim currently has faculty status through the Department of Organismal Biology at Portland State University and has held faculty status at Eastern Oregon University and Stockton State College (NJ).

Since moving to the Columbia River Fisheries Program Office, Tim has served as the team leader for the Conservation Assessment Section. His work focuses on the development and assessment of programs for conservation, monitoring and evaluation, specifically for listed species. Tim is currently involved in recovery planning, primarily focused on bull trout and Lower Columbia River salmon and steelhead as well as on issues regarding the relationship between resident and anadromous forms of O. mykiss.
