To contribute to the calculation of the value of Rhizophora apiculata population in Can Gio Mangrove Biosphere Reserve by studying of the biomass of individual tree and populations. Data were collected from 150 plots, each plot of 500 m2 (25 m × 20 m) and cut 42 trees with diameter (D1,3 m) from small to large to calculate biomass. The results of the study show that the allometric equation Y = a*Xb demonstrates the relationship between biomass and
trunk diameter. The results show that the average dry biomass of the Rhizophora apiculata population in Can Gio mangrove forest is 344.62 ± 106.38 tons/ha, ranging from 140.33 to 643.72 tons/ha. The population at the age of 7 years (age 33 - 37) had the highest average biomass with the values of 430.64 ± 88.63 tons/ha ranging from 266.49 to 643.72 tons/ha. The population at the age of 5 (aged 23 - 27) had the lowest dry biomass of 304.50 tons/ha, ranging from 140.33 to 541.68 tons/ha. The total biomass of the double
mangrove population in Can Gio mangrove forest reserve is estimated at over 6.35 million tons. The result will be a reference for calculations in future payments for forest environmental services
