BackAmerican beaver (Castor canadensis) and freshwater climate resiliency in Washington State
There is substantial evidence that beaver-related restoration, via beaver translocation and the construction of beaver dam analogues, has the potential to increase the climate resiliency of Washington’s stream and riparian ecosystems (summarized in Table 1). By reducing summer water temperatures, increasing summer flows, and enhancing floodplain habitat, beavers and beaver-related restoration can benefit species of conservation concern, including trout, salmon, and amphibians. In addition, beaver-related restoration can ameliorate the negative impacts of high-flow events, create fire-resistant habitat patches in fire-prone landscapes, and foster heterogeneous mosaics of habitat that enhance the watershed-level biodiversity of aquatic and riparian ecosystems. However, these benefits are only likely to accrue under certain conditions, and there is a gap between our understanding of the aspirational potential of beaver-related restoration (what it can accomplish) and the realized benefits of restoration actions (what it does accomplish).
