Restoration of the San Francisco estuary's tidal marshes has been focused on large-scale engineering solutions, while community composition and related ecological functions have received little attention in most projects. We evaluated plant-species richness and composition across twenty-one natural and restored marshes in the estuary, documenting fewer species in many of the restored marshes, some with only half as many species as in natural marsh remnants. Greater species richness tended to occur in marshes with gradual transitions to upland, heterogeneity in soil texture or topography, and close proximity to a seed source. We discuss how species identity and interactions can influence marsh functioning and consider ways in which greater species richness might be accomplished in upcoming restoration projects.
