The spatial distribution of blue carbon in the coastal wetlands of China
Salt marshes comprised the largest area of coastal wetlands in China, but inventories are difficult to obtain for China, and more generally globally as well (e.g., Mcleod et al., 2011 and Duarte et al., 2013 discuss how models predict a global coverage of up to 40 million ha, although only 2.2 million ha has been verified).
