Mangrove forests can store up to 1023 MgC ha−1, ranking among the most important carbon (C) sinks in the tropics (Donato et al.,2011). Recent studies have indicated that C storage by mangrove forests is two to three times higher than that of terrestrial forests (Adame et al.,2013; Donato et al., 2011; Kauffman et al., 2011).
