Corte Madera marsh is located on the western side of San Pablo Bay and covers 77 hectares. We surveyed 744 elevation points and 361 vegetation plots to determine baseline conditions of the marsh. Water level loggers deployed in 2010 were used to characterize the tidal inundation patterns throughout the year. Sediment accretion rates from soil cores at China Camp State Park marsh were extrapolated to Corte Madera marsh and used as input for the WARMER sea-level rise response model. WARMER projects that by 2050 Corte Madera marsh will be dominated by mid marsh vegetation and will transition into low marsh habitat by 2080.

The elevation histogram for Corte Madera shows the marsh platform is below MHW on average (Fig. 1). Data from the vegetation surveys indicate moderate low species richness (Fig. 2). Results from WARMER response model indicate that Corte Madera will lose relative elevation as sea levels rise (Fig. 3). The marsh platform at Corte Madera Marsh is projected to transition to low marsh habitat by 2050 and be below mean sea level by 2080 (Fig. 4). The percent of time Corte Madera Marsh is inundated varies throughout the year by season, with the most inundation during the winter (Fig. 5).(Public domain.)
