This study was conducted to assess the species diversity and carbon sequestration potential of a natural mangrove stand inBotoc, Pinabacdao, Samar, the Philippines. Using the quadrat sampling technique, 12 plots with a size of 100 m2 wereestablished to facilitate inventory and measurement of trees. Shannon-Wiener index and allometric equations were used todetermine species diversity, and biomass and tree carbon storage, respectively. The community’s species diversity (H0 ¼1.6365) was very low with a total of eight true mangrove species recorded, dominated by Avicennia officinalis with animportance value of 134.80%. Among the plots, a greater percentage of the total biomass was accounted to the abovegroundbiomass, corresponding to 74% (297.20 t ha1), while the remaining 26% (103.87 t ha1) was credited to theroot biomass. The total carbon sequestered and stored in the biomass of the natural mangrove stand was 188.50 t C ha1equivalent to 691.81 t CO2 ha1. The biomass and carbon density estimates acquired in this study suggest that natural mangroveforests in Botoc have the potential to sequester and store a huge amount of atmospheric carbon regardless of the verylow species diversity.
