Our project will produce a better understanding of how catastrophic changes in river channel morphology (e.g., landslides, rockslides, etc.) have affected Fraser salmon in the past, how the Big Bar Landslide is presently affecting Fraser salmon, and how and where future landslides will likely affect Fraser salmon. We will produce and share i) maps of potential future landslides and probable hydraulic barriers to fish passage for the entire Fraser Canyon, ii) spatially-resolved information of environmental (topography and velocity) and biological controls (fish body size, species) on upstream fish migration, iii) evaluations of how the Big Bar Landslide affected fish genetics, and iv) information on the historic frequency and magnitude of river blockages in the Fraser Canyon and how this could have shaped present-day salmon biodiversity.  Please see our reports, publications, presentations, and data sets to see our progress.
