Sunderbans has been declared as World Heritage Site by UNESCO in the year 1987. It is the world’s largest delta enclosed by thick mangrove forest and huge saline mud flats. It is also the world’s largest estuarine forest. A land consisting of 54 tiny islands, bisected and segmented by a number of tributaries of River Ganga, Sunderbans is spread throughout the area of 9630 sq. km. Way back in 1984, Sunderbans was hailed as a National Park and prior to that, during 1970s, it was known as Tiger Reserve.

Sunderbans is a house to large flora and fauna. It is also the breeding grounds of a variety of birds and many other unknown wildlife entities of the world. Till date, the largest number of wild tigers in the world is found in Sunderbans


The Riot of Colors…

Sundarbans derives its name from the mangrove or the “Sundari” trees which display around some sixty-four varieties. The mangrove vegetation can bear the estuarine conditions as well as saline inundations brought in by tides. During the period of April-May, the park goes into a riot of colors. The red blooms of Genwa (Excoecaria agallocha) find its match in the yellow blooms of Khalsi(Aegiceras corniculatum), making it one spectacular watch for the tourists. The red flowers with the crab-like shape called Kankra (Bruguiera gymnorrhiza) can also be seen during this time of the year. Other plants and trees that are found here are Dhundal or cannonball mangrove, Passur, Garjan, and Goran.

Mangroves Reduce Erosion


In general, the northern boundary of Sundarbans and the new depositions are occupied by Baen ( Avicennia marina , A. alba, A. officinalis ) and covered by foreshore Dhani grass (Oryza coarctata).

The southern and eastern parts include Kankra, Garjan (Rhizophora spp.), and thick patches of Sundari trees. Hental forest can be found in higher land with more compact soil.
