Synergetic Roles of Mangrove Vegetation on Sediment Accretion in Coastal Mangrove Plantations in Central Thailand

Mangrove plantations can potentially restore the vegetation structures protecting coastal areas. In Avicennia alba in central Thailand, we investigated (trees, seedlings, pneumatophores, and belowground roots), sedimentation rates, elevation changes over one year across shore. The results showed a heterogeneous structure with an increasing tree basal area (BA) seedling density towards interior. pneumatophore quantitative characteristics decreased interior association topographic gradient inundation period. which were greater plantation than on mudflat, negative correlation height, total surface area, volume of pneumatophores. This indicates that pneumatophores facilitated transportation fine sediments into Our suggest optimal complexity aboveground might enhance rates. According to BA density, root increased monthly less fluctuation those mudflat. net indicated sediment accretion within erosion demonstrate synergetic roles mangrove facilitate redeposition roots stabilize
