Table 1 Basic characteristics of the study sites (organic matter content, above-ground biomass, wetland area, vegetation area, dominant species) and mean soil organic carbon content in estuarine salt marshes, mean (5th to 95th percentile). N refers to number of sampling points from other studies. This is done by Monte Carlo simulation from values in literature. Source of references are listed in Additional file 1: Table S1

From: Estimation of carbon storage in coastal wetlands and comparison of different management schemes in South Korea
