Mangrove forests constitute the most important sink of carbon (C) in the tropics, the conservation of which is an essential mean in offsetting C emissions and climate change. Mangrove forests are therefore suggested to be an important component of reducing emissions from deforestation and degradation (REDD+) schemes, which require scrupulous quantification of ecosystem C storage in order to monitor temporal C sequestration and emissions. Despite this, proportionally less is known about ecosystem C storage of mangrove forests in Vietnam, where these systems constitute a large proportion of its coastline. In this study, ecosystem C storage of a tropical mangrove forest in Mui Ca Mau National Park, Vietnam (CMNP) was quantified by measuring biomass of trees, roots, and downed woody debris, and sediment organic C and overall depth. Results showed that above-and below-ground C stock ranged from 90.2 +/- 15.8 to 115.2 +/- 19.3 and from 629.0 +/- 32.5 to 687.0 +/- 29.2 MgC ha(-1), respectively. The combination of the above- and below-ground C stocks resulted in a high ecosystem C storage, which ranged from 719.2 +/- 38.0 to 802.1 +/- 12.3 MgC ha(-1), and slightly increased from fringe toward interior forest. The 13,400 ha of mangrove forests in the CMNP were estimated to store 10.3 (+/- 0.8) x 10(6) Mg of C, which is equivalent to 38.0 (+/- 3.0) x 10(6) Mg of CO(2)e. The present results suggest that the conservation of mangrove forest is needed to increase ecosystem C storage and to offset C emissions at the regional scale. () 2014 Elsevier B.V.
