Review: Coastal wetland blue carbon

wetlandswideCoastal wetlands (mangroves, tidal marshes and seagrasses) are important carbon sinks, in both biomass and soils. Howard et al. describe and quantify the carbon flow through these different coastal ecosystems, and their potentials as long-term carbon sinks. Unlike the open ocean, these coastal ecosystems fall into clear national jurisdictions, so they can be more readily protected through management strategies. The authors observe that coastal wetlands, as long-term carbon sinks, should be a priority for climate mitigation efforts. Front. Ecol. Environ. 10.1002/fee.1451
