Wave-driven erosion of marsh boundaries is a major cause of marsh loss, but little research has captured the effect of seasonal differences on marsh-edge retreat rates to illuminate temporal patterns of when the majority of this erosion is occurring.
The South Bay Salt Pond Restoration Project aims to restore many former salt production ponds, now managed for wildlife and water quality, to tidal marsh.
Despite fluctuations in acreages between years, the marshes and mudflat south of the San Mateo bridge appear relatively stable between the period 2009 – 2021, in that the relative proportions between different habitat types have not changed significantly. Within a number of restored ponds (e.g.,

The 30,000 acres of wetlands within the Don Edwards San Francisco Bay National Wildlife Refuge (Refuge) provide critical habitat for over one million waterbirds annually (Page et al. 1999, Warnock et al. 2002). These wetlands consist largely of tidal marshes and open water ponds.
The state and federally endangered California clapper rail (Rallus longirostris obsoletus) has declined in abundance and been reduced in range and now occupies fragmented intertidal saltmarsh only within San Francisco Bay.
Because high tides increase in elevation across South San Francisco Bay, and because tidal inundation structures tidal salt marshes plant zonation, species distribution models (SDMs) of salt marsh plants require integrated, spatially continuous measures of tidal patterns and elevation.
Early detection of invasive species is required for cost effective management of plant invasions, but finding nascent populations often requires extensive field surveys
