  1. Science Policy Exchange Habitat Issues Sep 12-13, 2007

  2. Science Policy Exchange Fish and Wildlife Program Assumptions • Incorporated in Fish and Wildlife Programs’ Scientific Principles • Based on:Independent Scientific Group’s Return to the River and its Conceptual Foundation Sep 12-13, 2007

  3. Alternative Conceptual FoundationReturn to the River (1996; 2006) • Salmonid life history diversity and habitat diversity are linked • Increases in habitat abundance, diversity, and connectivity increase salmonid life history diversity • Increases in habitat and life history diversity increase salmon production • Increased abundance and production increase resilience Sep 12-13, 2007

  4. Diversity – Productivity Linkage • Normative River Processes • natural ecological processes and functions • Habitat Complexityand Diversity • Biodiversity • life history, population, phenotypic, genetic • Salmonid Productivity • achieve or approach Council’s rebuilding goals Sep 12-13, 2007

  5. Alluvial River 3-D Ecosystem Sep 12-13, 2007

  6. FWP Scientific Principles 1. The abundance, productivity and diversity of organisms are integrally linked to the characteristics of their ecosystems. 2. Ecosystems are dynamic, resilient and develop over time. 3. Biological systems operate on various spatial and time scales that can be organized hierarchically. 4. Habitats develop, and are maintained, by physical and biological processes. Sep 12-13, 2007

  7. FWP Scientific Principles 5. Species play key roles in developing and maintaining ecological conditions. 6. Biological diversity allows ecosystems to persist in the face of environmental variation. 7. Ecological management is adaptive and experimental. 8. Ecosystem function, habitat structure and biological performance are affected by human actions. Sep 12-13, 2007

  8. Intensively Monitored Watersheds • Rationale for IMW approach • Quantify salmon response to habitat actions at a watershed level experiment • Extent of current efforts • Idaho, Washington, Oregon • Example results from an IMW effort: • Fish Creek • Speakers:Bob Bilby, Gordie Reeves Sep 12-13, 2007

  9. Habitat Strategies Current Habitat Strategies Increases in habitat capacity and productivity will lead to increases in fish and wildlife Assumes stable climate and human population Climate Change / Population Growth Restoration and habitat strategies need to account for climate change and population growth Examples and tools for planning Speakers: Susan Hanna, Peter Paquet Sep 12-13, 2007

  10. Nutrient Enhancement • Rationale • Harvest and downstream mortalities were depriving upriver systems of salmon carcasses and marine derived nutrients • Experiments / Case Studies • British Columbia, Oregon, Washington • Conclusions • Speakers: Pete Bisson, Matt Mesa Sep 12-13, 2007

  11. Discussion Periods • Time is limited • Focus on Science Summary and Policy Implications • Discussion • Exchange between Council members, managers, and scientists • Emphasis on policy and manager’s perspective Schedule Enforcers Sep 12-13, 2007
