Summary
The goal of this study is to use eDNA as a cost effective tool for documenting the occurrence and distribution of ESA-listed spring-chinook (Oncorhynchus tshawytscha) throughout the Okanogan and Methow watersheds in an effort to map habitat use and connectivity. Our approach will use eDNA to detect low density spring-chinook in filtered water samples to inventory distribution and re-colonization of tributaries at strategically-sampled points throughout entire stream networks. This approach will provide one of the first applications of eDNA technology for monitoring distribution of native fish species of conservation concern. The findings will help the Colville Tribe Fisheries Managers assess aquatic connectivity for chinook salmon [...]

The goal of this study is to use eDNA as a cost effective tool for documenting the occurrence and distribution of ESA-listed spring-chinook (Oncorhynchus tshawytscha) throughout the Okanogan and Methow watersheds in an effort to map habitat use and connectivity. Our approach will use eDNA to detect low density spring-chinook in filtered water samples to inventory distribution and re-colonization of tributaries at strategically-sampled points throughout entire stream networks. This approach will provide one of the first applications of eDNA technology for monitoring distribution of native fish species of conservation concern. The findings will help the Colville Tribe Fisheries Managers assess aquatic connectivity for chinook salmon and provide baseline data for future evaluations of anthropogenic stressors, such as climate change, land use, and invasive species. The proposed study is a partnership among USGS, Colville Confederated Tribes, Boise State University, University of Idaho and Bonneville Power Administration.
