Abstract :Aboveground biomass and productivity of a Rhizophora stylosa forest, which generally develops along the seaward edge of the coral reef type mangrove forests, were described using three times of census data from a permanent plot on a small island in the lagoon of Pohnpei Barrier Reef Island, the Federated States of Micronesia. As the aboveground root biomass had been underestimated by the existing allometric equations because of densely developed prop roots, we estimated it by detailed measurement. The ratio of prop root biomass was estimated at 58% of aboveground biomass of R. stylosa in the plot. Total aboveground biomass including that of the other species increased from 229 t ha-1 in 2003 to 254 t ha-1in 2011, indicating 3.2 t ha-1 yr-1 of annual increment. These values are apparently smaller than those of the mangrove forests fringing the main island of Pohnpei. The differences seem to be caused by the environmental stress induced by high salinity of soil water in this R. stylosa habitat.
