1) Variation in perceptions of the stormwater social-ecological system in Puget Sound: insights for management across the land-sea interface (Caitlyn O’Connor) I will investigate the perceptions of the impacts of non-point source pollution (stormwater) on the marine ecosystem in Puget Sound, Washington by eliciting regional expert opinions’ in the stormwater science and management realm. Specifically, my objectives are to: 1) Describe variation in the ways stormwater experts perceive the structure of the Puget Sound stormwater social-social ecological system. 2) Explore the consequences of differences in variation in perceptions in the stormwater social-social ecological system for management. 3) Develop a consensus model of the Puget Sound stormwater social-ecological system that can be used to support management decisions. These objectives build off one another to end with a tool that will hopefully enhance our understanding of the impacts of emerging contaminants (stormwater), improve our knowledge of the transport of pollutants in the Puget Sound ecosystem, and preliminarily evaluate the perception of how much recovery needs to happen. 2) How can Floodplain Restoration Enhance Streamflow and Salmon Habitat in the Stillaguamish River? (Ashley Bagley) This project builds upon the Stillaguamish Tribe’s traditional knowledge and collaborations with Snohomish County to predict where floodplain restoration can provide the greatest increase in salmonid habitat by amplifying groundwater-surface water exchange. Our study includes five areas within the North and South Forks had warmer temperatures than side channels and tributaries. Further statistical analysis is needed to identify specific reaches that would create the most beneficial salmonid habitat. The Stillaguamish Tribe and Snohomish County will be able to use the study results for future hydrologic modeling of groundwater-surface water interactions using collected water quality data, and in the evaluation of large wood installations planned for 2019.
