Abstract: We used a loosely linked system of models of climate, land cover, hydrology, and salmon population dynamics to investigate the impacts of climate change and habitat restoration on Chinook salmon populations in the Snohomish river basin in western Washington. Model results indicated a large negative impact of climate change on freshwater salmon habitat but also suggested that habitat restoration and protection could help to mitigate these effects and might allow populations to increase in the face of climate change. The habitat deterioration associated with climate change is, however, likely to make salmon recovery targets much more difficult to attain. In this talk, we outline our approach and discuss the benefits and challenges of using this methodology to assess salmonid responses to climate change.
