  abstract = {{M}angrove forests can fix and store high quantities of carbon both in their soil and in their biomass, the latter peaking in the equatorial regions and decreasing with latitude. {I}n {V}ietnam, more than 80% of the mangroves develop either in the {M}ekong {D}elta or in the {C}an {G}io {E}stuary, which are characterized by tropical monsoon climates. {M}ost of these mangroves were planted and are dominated by {R}hizophora apiculata {B}lume. {T}he main objectives of this study were to determine forest structure, above-ground biomass and carbon conversion factors for each tree component in order to obtain allometric equations and to derive carbon stocks for managed {R}hizophora stands of different ages developing within this context. {T}hirty-six trees, having a diameter at breast height ({DBH}) ranging from 7.0 to 36.2 an, from a planted mangrove forest were harvested in {C}a {M}au ({M}ekong {D}elta) to determine allometric equations. {I}n addition, thirteen plots were established in both {C}a {M}au and {C}an {G}io mangrove forests, to determine above-ground carbon densities. {W}e proposed the following specific allometric equation to estimate total above-ground biomass (kg) for managed {R}. apiculata mangrove stands in {S}outhern {V}ietnam: {W}-{T}otal = 0.38363 * {DBH}2.2348 ({R}-2 = 0.976, {SE} = 1.17, {F} = 1401, {P} < 0.001). {T}he total above-ground biomass ranged from 135.4 to 523.6 {M}g ha(-1) depending on forest age and tree density. {C}onsequently, and taking into account a carbon conversion factor of 44.09%, carbon stocks in the above-ground biomass of {R}. apiculata mangrove forests in {S}outhern {V}ietnam ranged from 59.7 to 230.9 {M}g {C} ha(-1). {T}he mean carbon partitioning in the tree biomass was: 77.11% for trunks, 11.87% for branches, 8.66% for prop roots, and 2.36% for leaves. {H}owever, this distribution, as well as annual height increments and biomass increase rates, also varied with forest age and tree densities. {W}e suggested that tree density reduction through thinning activities allowed easier tree development, resulting in an increased biomass with enhanced allocation to branches and above-ground prop roots for the stability of the trees. {U}sing the specific allometric equation and specific carbon conversion factor reduced the uncertainty in the estimation of above-ground biomass and carbon stocks.},
