Blog: A bird’s eye view on Bay Area marshes (via unoccupied aerial systems) yields new insights
The Sonoma Land Trust restored the 940-acre Sears Point Tidal Marsh Restoration Project to tidal action on October 25, 2015 and the project is now part of the San Pablo Bay National Wildlife Refuge managed by the U.S. Fish and Wildlife Service. The constructed design for this subsided diked bayland allows natural sedimentation to raise site elevations relatively rapidly from around low tide heights at breach up to intertidal emergent marsh elevations, drawing upon the known high sediment loads of northern San Pablo Bay. The design also included a setback flood protection “habitat” levee with gentle slopes (10:1 to 20:1) and around 500 “marsh mounds” within the site interior.
