Research with real-world impact
Our work combines field ecology, conservation genetics, aquatic monitoring, and decision-making to understand and protect freshwater ecosystems.
01 · CONSERVE
Conservation of Freshwater Fishes
Investigating the ecology, habitat requirements, and recovery of imperilled freshwater fishes including Bull Trout and other native species.
02 · SUSTAIN
Sustainable Resource and Land-Use Development
Investigating how resource development and land-use activities affect freshwater ecosystems, and developing science-based approaches to minimize environmental impacts.
03 · RESTORE
Restoration and Reclamation
Developing science-based approaches to habitat restoration, offsetting, and aquatic conservation planning.
Research Expertise
Applied Fisheries Research
From field surveys to advanced laboratory and quantitative approaches, our team uses a diverse range of tools to understand and conserve freshwater ecosystems.
