  1. Life History Patterns and Habitat Use in the Upper Columbia Greer MaierScience Program ManagerUpper Columbia Salmon Recovery Board

  2. GOALS OF THE SESSION • Improve current understanding of life history and habitat use of listed salmonids in order to inform ongoing recovery plan implementation. • Create dialogue between project sponsors, decision-makers, and research and monitoring entities. • Generate a summary of information gaps and current information about life history and habitat use of UC populations.

  3. WHY IS LIFE HISTORY IMPORTANT? • Diverse life histories contribute to population resilience. • Habitat opportunity, capacity, and performance can be greatly influenced by life history (and vise versa)AND  Habitat opportunity, capacity, and performance can greatly influence population capacity, growth, and productivity (and vise versa) • Effective and efficient recovery strategies, actions, and decisions are often based on our understanding of life history and habitat use.

  4. WHAT IS LIFE HISTORY? • Life history is defined as the combination of traits exhibited by an organism throughout its life cycle. • Life history characteristics can be imagined as various investments and tradeoffs in growth, reproduction, and survivorship.

  5. WHY IS LIFE HISTORY IMPORTANT? Simenstad and Fresh

  6. HOW ARE HABITAT & LIFE HISTORY LINKED? Simenstad and Fresh

  7. WHAT DRIVES LIFE HISTORY? • Long-Term (generations) • Genetics • Habitat and Environmental Conditions • Short-Term (year-to-year) • Individual Behavior • Growth and Performance • Carrying Capacity • Habitat and Environmental Conditions

  8. WHAT DRIVES LIFE HISTORY? Simenstad and Fresh

  9. EXISTING RESOURCES • General life history patterns in UC (e.g. Chapman et al. 1995, Peven2003, UCSRB 2007, Andonegui2001) • Emerging Research (e.g. Tomaro et al. 2012, Miller 2011, Tucker et al. 2011, Benjamin et al. 2012) • PIT Tag Datasets • Ongoing modeling efforts

  10. General Life History PatternsSPRING CHINOOK Summer Parr Rearing Early Spring Emergence Fall Juvenile Redistribution Late Summer (August-Sept peak) Spawning Juvenile Overwintering Spring (May Peak) Smolt Migration Spring (Mid-May peak) Adult Migration Days-to-months estuarine rearing 1-4 years (2-3 average) ocean rearing

  11. General Life History PatternsSTEELHEAD Fall Parr Rearing Summer Emergence Juvenile Rearing 1-7 years (2-3 years average) Following Spring (April peak) Spawning Summer (Aug-Sept Peak) Adult Migration Spring (April-May Peak) Smolt Migration Days-to-months estuarine rearing 1-4 years (2 years average) ocean rearing

  12. FOCAL SPECIES & LIFE STAGES • Spring Chinook, Steelhead, and Bull Trout • Adult Migration/Holding • Spawning • Fry • Summer Parr • Winter Juvenile • Emigrant

  13. KEY QUESTIONS • BY LIFE STAGE, BY SUBBASIN: • Timing • Age-structure • Areas of occupancy and use • Movement and Behavior • Habitat characteristics and environmental factors • Survival, growth, and carrying capacity
