Joe Evenson
Marine Bird Specialist

Joe Evenson joined WDFW in 1994 to work on the Marine Bird and Mammal Component of the Puget Sound Assessment and Monitoring Program (PSAMP). His research has focused on population status and trends of marine birds in the Puget Sound and evaluating population dynamics of sea ducks. 

He received a B.S. in Biology from the Evergreen State College in Olympia, WA in 1990.  From 1990 – 1995 he worked as a research biologist with Cascadia Research studying marine mammals and birds along the North East Pacific Coast, from Alaska to California, as well as the Arctic Ocean.  These projects focused on population estimates utilizing aerial and vessel survey and mark-recapture methodologies. 

Current Research
