Figure showing location of the study area and details of the simulated restorations in San Mateo County, California

Location of the study area and details of the simulated restorations. (A) and (B) Location of this study, shown by the red dot in (A) and the orange line in (B). The thin white boxes in (B) show the extent of the maps in (C), (E) and (F) and the thick white box in (B) shows the extent of the map in (D). (C) Vertical offset applied to the restoration sites to simulate sediment accretion/nourishment, bringing each site to + 1 m relative to mean sea level. These values range from 0.05 to 1.1 m. (D) Levee breaches across historical marsh channels to facilitate tidal connectivity in salt ponds are shown in blue. (E) Current and (F) restored marsh habitat types, determined by elevation relative to tidal datum, as shown in Eq. 1. The three shades of green, from dark to light, denote low, transition, and high marsh habitat.
