Implications and Applications of Life History and Habitat Use Information Greer MaierScience Program ManagerUpper 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.

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?
