Beavers & Bull Trout Study

A long history of cattle grazing, channel straightening, and beaver trapping has left many streams in western North America degraded and down-cut. Beaver dam analogues (BDAs) have become a popular tool for remedying degraded systems. However, it is not known whether federally-threatened Bull Trout are able to move upstream of beaver dams during their fall spawning runs – a time of the year characterized by low flows. With project partners at Utah State University and the Bitter Root Water Forum, I am working to determine if Bull Trout are able to pass beaver dams and whether or not BDAs should be used in streams with Bull Trout populations.
