This study was conducted to assess the species diversity and carbon sequestration potential of a natural mangrove stand in Botoc, Pinabacdao, Samar, the Philippines. Using the quadrat sampling technique, 12 plots with a size of 100 m 2 were established to facilitate inventory and measurement of trees. Shannon-Wiener index and allometric equations were used to determine species diversity, and biomass and tree carbon storage, respectively. The community's species diversity (H' = 1.6365) was very low with a total of eight true mangrove species recorded, dominated by Avicennia officinalis with an importance value of 134.80%. Among the plots, a greater percentage of the total biomass was accounted to the aboveground biomass, corresponding to 74% (297.20 t ha(-1)), while the remaining 26% (103.87 t ha(-1)) was credited to the root biomass. The total carbon sequestered and stored in the biomass of the natural mangrove stand was 188.50 t C ha(-1) equivalent to 691.81 t CO2 ha(-1). The biomass and carbon density estimates acquired in this study suggest that natural mangrove forests in Botoc have the potential to sequester and store a huge amount of atmospheric carbon regardless of the very low species diversity.
