The total carbon stock of the Sofala Bay mangrove forest is 218.34 Mg·ha−1
(Table 4), around 85%
of which is stored below-ground (73.28% in the soil and 11.55% in the roots). Our results are
supported by the findings of Kauffman et al. [51], who also found similar fractions of carbon stock in
mangrove soils of some Federated States of Micronesia. In other studies, soil carbon accounted for
72%–99% [8,14] and 40%–98% [8] of the total mangrove ecosystem carbon
