Implications and Applications of Life History and Habitat Use Information Greer Maier Science Program Manager Upper Columbia Salmon Recovery Board
GOALS OF THE SESSION Discuss ideas for applying life history and habitat use information to project development, design, and decision- making. Learn about ongoing implications and applications of information on life history and habitat use. Generate a summary of applications and implications of life history and habitat use information in the Upper Columbia.
Current Abundance SAR WHY CONSIDER LIFE HISTORY? EGG-TO-EMIGRANT SURVIVAL PRE-SPAWN MORTALITY Target Abundance
FRESHWATER SURVIVAL GAP CURRENT STL: 2,100% Gap SP CHN: 670% Gap Target Egg-to-Emigrant With 2% SAR STL: 1,100% Gap SP CHN: 238% Gap With 2% SAR & 40% PSM STL: 880% Gap SP CHN: 330% Gap WHY CONSIDER LIFE HISTORY?
Some Thoughts.. By maximizing habitat that not only supports current life history strategies but also enhances opportunity for future life history diversity we maximize our contribution to recovery. By taking into consideration life history we can target the habitat requirements that lead to the greatest improvement in survival and performance at a particular site and reach.
SOME EXAMPLES Snake River (e.g. Snake River SRB) Trinity River (e.g. Goodman et al. 2009) Columbia River Estuary (e.g. Bottom et al. 2011) EDT Subbasins (e.g. Okanogan OBMEP)
SESSION KEY QUESTIONS Incorporating life history requirements/habitat preferences into projects – examples and considerations? Type of information on life history/habitat use has been or should be used? Life history requirements that need to be considered in projects? In permitting? How does carrying capacity play into life history and habitat use strategies? What tool are available to help us incorporate this information?
