This document summarizes the importance of wetland restoration in San Francisco Bay. It discusses how wetlands were filled in starting in 1850 due to pollution and development, but restoration efforts since 1998 have helped restore over 100,000 acres of wetlands. Wetland restoration provides key benefits like habitat for fish and wildlife, filtering of pollutants, erosion control, flood prevention, and carbon absorption. The document also recommends prohibiting development in undeveloped shorelines vulnerable to sea level rise in order to provide opportunities for wetland habitat restoration. Photos illustrate threatened baylands, flood risks, sea level rise impacts, and examples of terraced levees and wetland restoration projects.
