Description:Beschta and Ripple disagree with conclusions from our recent analysis of river planform change in Olympic National Park (East et al., 2017). Beschta and Ripple (2008, 2017) believe that a trophic cascade consisting of wolf eradication, increase in elk abundance, and herbivory impacts on riparian vegetation has been the paramount driver of geomorphic change. Although the trophic-cascade hypothesis is a valuable consideration for understanding riverine systems (Beschta and Ripple, 2006), we find that multiple physical processes have dominated river-planform change in the glaciated, temperate-rainforest valleys of Olympic National Park. In our view, the evidence does not support the Beschta and Ripple conceptual model that these rivers owe their sensitivity to physical drivers to overarching dominance of trophic cascades. Further, we caution against viewing patterns of change in complex, multicausal systems through the lens of a single favored explanation (Mech, 2012; Peterson et al., 2014).
