A mangrove lagoon joined to the sea by a narrow canal and containing 15 islands of varying size, some of which are inhabited. It is formed of two shallow waterbodies, Maduganga and smaller Randombe Lake, connected by two narrow channels.
On the islands and shores relatively undisturbed mangrove vegetation contains a rich biodiversity qualifying the wetland for 7 Criteria of International Importance. Many globally/nationally endangered, endemic and rare species.
The cultural heritage is very prominent, with numerous ancient temples in the area and on the islands.
Maduganga helps in flood control by storing water during monsoon rains and retains nutrient run-off from nearby cinnamon plantations. The major occupation of the local people is fishing and agriculture (cinnamon and coconut).
Poaching of wild animals and waterfowl is unfortunately increasing, and extensive use of fertilisers and consequent abundant growth of invasive species, e.g. Najas marinas or Annona glabra, many more plastics and polythene are factors of concern.
