Summary
Rick Williams, a scientist from Eagle, Idaho, moderated the two-day exchange. Dr. Williams, former chair of the Council’s Independent Scientific Review Panel and an expert in population and evolutionary genetics and ecology, facilitated the Science-Policy Exchange and helped focus the discussion sessions on the policy ramifications of the emerging scientific issues and how they might inform the upcoming Fish and Wildlife Program amendment process.
Results and recommendations from the Exchange are based around the habitat, mainstem, estuary, and ocean themes. For each theme, the report includes: the guiding assumptions from the Fish and Wildlife Program; the state of current science; consistency of the current science with program assumptions; and policy recommendations or implications derived from the roundtable discussions. Each session ends with the questions, answers, and insights from the roundtable discussion period.
