  • The article compares the net primary production of an estuarine mangrove stand to an island fringing stand in Dutch Bay in northwestern Sri Lanka.
  • Net above-ground primary productivity was measured by monitoring litterfall and above-ground biomass increment between 1985 and 1987.
  • Estuarine mangrove stands recorded a higher annual rate of above-ground net primary production (1207.88 g mm2 or approximately 12 t ha-1) than the fringing mangrove stands (694.22 g m2; approximately 7 t ha-1).
  • The authors attribute variations between the two stands to the differences in tidal flushing and influence of freshwater in the two localities.
