Expert Panel

• Purpose
• Initial Guidance to Oregon
• Working Hypotheses to be evaluated

4
EP Ground Rules

• Based on data perspectives
• Limited Time to Deliberate

6
EP Benefits

• Life Cycle Landscape Perspective
• Independent Not Agency Perspective
• Stimulates Analysis Monitoring
• May Support or Challenge the Obvious
• Will Not Restrain Restoration where more Detailed
  Information Exists

Status of Panels

• Draft for LCR coho
• MC steelhead, LCR Chum, Chinook, Steelhead are
  Complete
• Upper Willamette due in May
• Expect remaining Reports end-May
