Project Description

This project will perform a GIS-based analysis and prioritize Southern California streams as translocation sites for rescued native rainbow trout. The FishPass GIS framework will be used to create a new layer that includes So Cal rainbow trout current and historical occupancy data, genetic lineage, and habitat characteristics. From this, translocation-ready sites will be prioritized as refugia for rescued trout in collaboration with CDFW regional fisheries scientists, and ten sites ground-truthed for site visits and data collection.
