INDIA ~ Sundarban National Park - UNESCO ~

... This makes collecting National Parks so much funヅ... you can get plenty of postcards from the same NP... but they all look so different... this one shows the breathing roots of mangrove forest in Sundarbans... it stands out to be the largest tangle of mangrove wetland in tropical Asia....unfortunately overflowing salty water and less rain has been a great threat for this unique natural beauty...Thanks a lot Chetan!!【ツ】

From backside postcard:
The Surdarban is a contiguous natural region in India and Bangladesh formed on the delta of the Ganges, Brahmaputra and Meghna rivers. It is the largest estuarine mangrove forest in the world. It is a NP, Tiger Reserve, Biosphere Reserve, UNESO WHS and a Ramsar wetlands.
Sonneratia species grow in oxygen-poor sediments. The underground root system needs and demands oxygen, the soil is not able to support the underground root system with enough oxygen. Therefore, the underground root system outgrows aerial roots that grow vertically up to the air above the soil. The cone roots have numerous lenticels that enable gas exchange directly above the surface. The cone roots provide the additional needed oxygen which can't be taken from the soil.
The Sundari tree (Heritiera fomes), from which Sundarban derives its name, breathes through pneumatophores or breathing roots that look like stilts. It is spread out in an area of almost 1,330 square kilometer in India.

Surbandans National Park was added to the UNESCO WHS list in 1987.
