Jennifer is engaged in work to protect and restore stream flows, and address other key limiting factors for salmonid recovery in California. Jennifer has managed and participated in numerous habitat restoration and monitoring projects on the North Coast of California. Her experience includes riverine restoration project development, management, implementation, and effectiveness monitoring; riverine habitat, stream flow, and aquatic species monitoring; conservation planning; and convening diverse groups of landowners, scientists and restoration practitioners to demonstrate solutions to freshwater and forest restoration and management challenges.
Prior to joining the Conservancy, she worked on the restoration of the tidal marsh at Crissy Field in the Golden Gate National Recreation Area, and as an organic farmer. She holds a B.A. in Diplomacy and World Affairs from Occidental College, and an M.S. in Ecology and Systematic Biology from San Francisco State University.
What Jennifer is working on now:
I'm currently engaged in efforts to design and implement voluntary streamflow enhancement projects, and identify science and policy bottlenecks to wider implementation of such projects. I am also working to develop, implement and test freshwater and salmon habitat restoration and management practices to provide habitat for salmonids and increase coastal resiliency in the face of sea-level rise due to climate change.
