Phillip Dionne, M. Sc.
Research Scientist, Nearshore & Forage Fish Ecology

Phillip Dionne has been with the Washington Department of Fish & Wildlife, Habitat Science Team, since 2012. His current research interests are monitoring effects of shoreline modification on nearshore habitat, identifying and assessing the distribution and characteristics of forage fish spawning habitat, assessing new methods of detecting forage fish spawn, and monitoring the implementation of marine bulkhead HPA permits to help inform the development of a more effective permit system. Prior to joining the habitat program Phill’s research included work with the WDFW Fish Program using mark – recapture, and acoustic telemetry to assess abundance of Endangered Species Act (ESA) listed Green Sturgeon (Acipenser medirostris) in Washington and Oregon estuaries, and using estimates of larvae density to estimate spawning stock biomass of ESA listed eulachon (Thaleichthys pacificus) returning to the Columbia River.
