Michael M. Pollock, Ph.D.

Research Fish Biologist


As an Ecosystems Analyst, Dr. Pollock has been studying watersheds and fluvial ecosystems for more than two decades. During this time he has engaged in a diverse suite of scientific studies including: the influence of disturbance and productivity on biodiversity patterns in riparian corridors, the influence of beaver habitat on coho smolt production and ecosystem function, the historical patterns of riparian forest conditions in the Pacific Northwest, and the importance of riparian forests to maintaining stream habitat. Dr. Pollock also provides policy analyses to parties interested in understanding the potential effects of proposed or existing laws, policies, and regulations on our environment. Past analyses include the environmental impact of habitat conservation plans (HCPs), the likely effect of proposed state legislation concerning the protection of salmonid habitat, and the probable environmental impacts of various specific land use proposals. Dr. Pollock holds a B.S. in Biochemistry (California State University, Humboldt, Cum Laude) and a Ph.D. in Ecosystems Analysis (University of Washington, College of Forest Resources). Prior to joining the Watershed Program in 1999, Dr. Pollock was a partner in a local consulting firm and director of a small, non-profit scientific research institute.
