Coastal wetland ecosystem dynamics

Coastal wetlands—mangrove forests, tidal flats, and salt marshes—occupy the narrow zone where land and sea meet, and researchers studying them work to understand how these ecosystems function, change, and provide services that extend far beyond their shorelines. Because mangroves and tidal wetlands store carbon at rates that rival or exceed tropical rainforests while simultaneously buffering coastlines against storm surge and erosion, they sit at the intersection of climate science, ecology, and disaster risk reduction. As sea levels rise and human development fragments wetland habitats, a central question is how much of this ecological function can be recovered through active restoration, and under what conditions restored wetlands develop the structural complexity needed to match the carbon storage and protective capacity of intact ones. Researchers are also working to quantify the tipping points at which sediment dynamics, salinity shifts, and inundation frequency push these systems past recovery, which has direct consequences for how coastal communities and policy makers prioritize conservation investments.
