  • Rhizophora mucronata (native)
  • Avicennia marina (native)


  • This article compares the structural diversity of six mangrove stands of both estuarine and island-fringing types in Puttalam lagoon and Dutch Bay in northwestern Sri Lanka.
  • Using belt transects, the authors measured floristic composition, tree height and leaf-area index.and calculated density, basal area and mean stand diameter. Standing above-ground biomass was also measured and compared to dbh using destructive sampling methods.
  • Estuarine mangals had a greater structural complexity (complexity indices 8.1 l-22.7) than the mainland and island fringing mangals (complexity indices 1.38-6.78).
  • The authors attribute this to differences in tidal flushing and nutrient and salinity regimes between the study sites.
  • They also add that the low complexity index-values may have resulted due to the low number of species present, masking their relative ecological importance. As such, they suggest that complexity index may not adequately indicate the structural complexity and functional capacity of a mangal comprised of a few species.
