WERC Cogswell figures

The elevation histogram for Cogswell Marsh shows the marsh platform is above MHW on average (Fig. 1). Data from the vegetation surveys indicate very low species richness (Fig. 2).  Results from WARMER response model indicate that Cogswell will lose relative elevation as sea levels rise (Fig. 3). The marsh platform at Cogswell Marsh is projected to transition to low marsh habitat by 2060 and be below mean sea level by 2090 (Fig. 4). The percent of time Cogswell Marsh is inundated varies throughout the year by season, with the most inundation during the winter (Fig. 5)
