  abstract = {{M}angroves play a key role in carbon sequestration along tropical and subtropical coastlines, mainly as a result of their high primary productivity and the anoxic character of their soils, in which organic matter decay processes are slow. {U}nfortunately, these forests are disappearing worldwide, notably due to aqua culture and the need for space on the shoreline. {T}he mangrove area in {V}iet {N}am decreased substantially until late 90's, which was a concern for the {V}ietnamese government. {T}hen, replantation programs were developed in order to protect the shoreline against the erosion; like in northern {V}iet {N}am, where monospecific stands were planted from the mid 90's. {W}ithin this context, our objectives were to determine carbon stocks and carbon burial rates in the soil of a 18 years old {K}andelia obovata ({S}heue, {L}ui & {Y}ong) mangrove forest. {T}hree plots were set up in the planted mangroves and three in adjacent bare land (without any mangrove) at the mouth of {R}ed {R}iver. {T}hree geo-slicers up to 100 cm depth were taken in each plot; and in each core, ten soil samples were collected with a 10 cm depth interval. {L}ater on, dead and live roots were sorted. {C}arbon contents in soils and in roots were determined using the {W}alkley-{B}lack method and loss on ignition ({LOI}) method, respectively. {T}hen, the total belowground carbon sequestration was estimated. {T}here was a depth related distribution of organic carbon in soil with the highest concentrations measured between 20 and 60 cm depth. {A}ccumulated carbon up to depth of 100 cm in soil and roots of the planted {K}. obovata were 146.78 +/- 3.87 {M}g {OC} ha(-1) and 12.67 +/- 0.14 {M}g {OC} ha(-1), respectively. {T}he value was 87.59 +/- 1.08 {M}g {OC} ha(-1) for the adjacent bare land. {C}onsequently, the mean carbon burial rate for this system was approximately 6.94 {M}g {OC} ha(-1) yr(-1), which is higher than most of the mangroves and may be related to a low export of the net primary productivity or most likely to a high sedimentation rate. {T}hese results were compared with previously published results on carbon stocks in younger planted forests of the same species in the same region, a positive and linear relationship was determined between the age of the planted stand and the below ground carbon stocks.},
