It’s been a long summer of extreme drought conditions in Sonoma Valley. In what seems like a steady stream of dire news for our watershed one glimmer of good news stands out: beavers are moving back into Sonoma Creek.
The return of these charming dam builders isn’t quite breaking news – since 1993 beavers have slowly made a comeback in Sonoma Valley. But this year, in the middle of our peak dry season, their increasing presence is something for celebration. From the perspective of drought resiliency and water retention in our watershed we’re observing how beavers are a positive factor in keeping what water we do have flowing in our creek beds and reducing hydrological impacts of water rushing through the main stem of Sonoma Creek.
Their natural impulse to build dams and create ponds is a major factor in retaining refuge habitat for species that rely on water to survive. Beavers provide refuge habitat for endangered salmonids, crawdads, California roach, Sacramento suckers, frogs and the endangered California freshwater shrimp which rely on deep pools and submerged, structural habitat like fine tree roots which are often present in the structure of a beaver dam. Any animal, insect, or crustacean that requires water to live in our creek is something that benefits from the damming that the beavers do.
