Tidal Marsh and Tidal Flat Abundance


View Original Image at Full Size

Figure 3: This graph shows the amount of tidal marsh and tidal flat (collectively tidal wetlands) before and after European settlement and development of the San Francisco Bay shoreline. Salt ponds, diked wetlands, and agricultural baylands are areas separated from the Bay by levees and used for human use, such as salt production, duck hunting and outdoor recreation, and farming practices. Bay Fill refers to material, such as sediment and debris, used to fill in wetland areas for development or other uses. These areas can be seen in the satellite image in Figure 1.
