Abstract Salt marshes have ecological and economic value, but shoreline development, the increasing rate of sea-level rise, other human impacts caused significant loss salt marshes. As a result, restoration these ecosystems is widespread. For management to be effective, it imperative improve our understanding marsh-building plants that serve as foundation habitats. Given observed differences in characteristics between populations smooth cordgrass, Spartina alterniflora , plantings may impact biodiversity resilience restored ecosystems. Understanding structural functional outcomes active planting sites will enable long-term success efforts improved. Natural Long Island Sound were studied 2021–2022 for S. genetics, biomass, stem morphology, faunal community composition.
