Evolving Science and Policy to Restore Streams Using Instream Obstructions and Beaver Dam Analogues

06 April 2016
9:00am - 5:00pm

Workshop Coordinator:
Eli Asarian, Riverbend Sciences

Instream structures such as beaver dams, wood jams, living vegetation, and other obstacles that slow the downstream movement of water and sediment are essential to the restoration of streams. These obstructions can be used to accelerate the development of "stage zero" channels (Cluer and Thorne 2013) which are increasingly recognized as having intrinsic high value because of the multiple and synergistic ecosystem goods and services that such systems provide. Stage zero channels have well connected floodplains with elevated water tables, spatially variable hydrologic regimes and structurally complex aquatic and riparian habitat. As such, they provide incredibly valuable habitat for a suite of terrestrial and aquatic taxa, including several Pacific salmon species that are in decline.

This workshop will provide a state-of-the science overview of recent innovations in the construction of instream obstructions in California and their use in stream restoration, particularly for building stage zero fluvial ecosystems. Following the presentations there will be in-depth group discussions about how restorationists and permitting agencies can move forward together to improve the process for permitting innovative and adaptive restoration projects in California.
