that influence nutrient retention in mangrove forests include resorption of nitrogen
prior to leaf fall, burial of detritus by crabs, efficient nutrient uptake, high investment in chemical defences, variations in tidal inundation, sediment type, rainfall,
climatic disturbances, and topography.
High nutrient loading in mangrove ecosystem posses several adverse impacts on
coastal waters and adjacent habitats as listed in Table 4.13.
