Table 2. Allometric equations used to calculate aboveground and belowground biomass of mangrove trees.
| Aboveground biomass | ||
| Tall and medium mangroves | Reference | |
| R. mangle | Biomass: log10 B = 1.731*log10 DR - 0.112 | Smith and Whelan [33] |
| Leaves: log10 B = 1.337*log10 DR - 0.843 | ||
| Stem: log10 B = 1.884*log10 DR - 0.510 | ||
| Branch: log10 B = 1.784*log10 DR - 0.853 | ||
| Prop roots: log10 B = 0.160 *log10 DR - 1.041 | ||
| A. germinans | Biomass: log10 B (kg) = 1.934*log10 DBH (cm) - 0.395 | |
| Leaves: log10 B = 0.985*log10 DBH - 0.855 | ||
| Stem: log10 B = 2.062*log10 DBH - 0.590 | ||
| Branch: log10 B = 1.607*log10 DBH - 1.090 | ||
| L. racemosa | Biomass: log10 B (kg) = 1.930*log10 DBH (cm) - 0.441 | |

| Stem: log10 B = 2.087*log10 DBH - 0.692 | ||
| Branch: log10 B = 1.837*log10 DBH - 1.282 | ||
| Dwarf mangroves | ||
| R. mangle | Ln B (g) = 2.528+(1.129 (Ln D30 2 (cm))+(0.156* Ln Crown Volume (cm3)) | Ross et al. [32] |
| A. germinans | Ln B (g) = 2.134+(0.895 (Ln D30 2 (cm))+(0.184* Ln Crown Volume (cm3)) | |
| Belowground biomass | ||
| All mangroves | ||
| R. mangle | B (kg) = 0.196*(1.050.899)* (DR 2)1.11 | Komiyama et al. [35] |
| A. germinans | B (kg) = 0.196*(0.900.899)* (DBH2)1.11 | |
| L. racemosa | B (kg) = 0.196*(1.050.899)* (DBH2)1.11 | |
B = biomass; DR = diameter above highest prop root; DBH = diameter at breast height; D30 = diameter at 30 cm from the ground. Wood density values used for calculating belowground biomass were obtained from Zanne et al [36].
