![]() Depending on the climate and hydrological conditions, coastal wetlands can be grouped into several categories including mangroves, seagrasses, tidal salt marshes, or mud flats. ![]() ConclusionsĪlthough our study sites do not cover all types of large marine ecosystem, this study highlights the substantial contribution of coastal wetlands as carbon sinks and the importance of conserving these habitats to maximize their ecosystem services.Ĭoastal wetlands are highly productive transient zones located between terrestrial and marine ecosystems (Mitsch and Gosselink 2015). The value of US $6600 ha −1 is ~ 45% of previously estimated ecosystem services from fishery production and water purification functions in coastal areas. The economic value of stored carbon was estimated by comparison with the price of carbon in the emission trading market. Mean carbon storage in tidal flats ranged from 18.2 to 28.6 kg C m −2, with variability possibly related to soil texture. Mean carbon storage in two salt marshes ranged between 14.6 and 25.5 kg C m −2. Bulk density, soil organic matter content, and standing biomass of vegetation were all considered, with Monte Carlo simulation applied to estimate the uncertainty. Data were collected from three tidal flats (one protected and two developed areas) and two estuarine salt marshes (one protected and one restored area). In this study, organic carbon storage in coastal wetlands and its economic value were estimated using the raw data of 25 studies related to soil carbon storage. Organic carbon stored in coastal wetlands, which comprises the major part of oceanic “blue carbon,” is a subject of growing interest and concern. ![]()
