We obtained data from three sources: the National Mangrove Resource Inventory Report in 2002 (Ministry of Forestry, 2002), published biomass and soil C data in the literature, and collections and measurements by ourselves for this study. The National Mangrove Resource Inventory Report in 2002 was the most comprehensive inventory available and provided the area and forest type classification data. The survey was conducted in 2001 and the State Forestry Bureau issued National mangrove survey technical regulations and organized training programs. This report included inventory data covering 95,680.9 ha and 5909 compartments and contains data on area, distribution, community types, land
ownership, forest ownership, origin, mangrove plantation age, canopy density, tree height class, and mangrove management situation.
We used this report to determine the main community
types and community areas.
