Why Sundarban is a world heritage site

 

The Sundarbans mangrove forest, one of the biggest such woods on earth (140,000 ha), lies on the delta of the Ganges, Brahmaputra and Meghna rivers on the Bay of Bengal. It’s adjacent to the boundary of India’s Sundarbans World Heritage site inscribed in 1987. The website is intersected by a intricate network of tidal waterways, mudflats and smaller islands of salt-tolerant mangrove woods, and presents a superb example of ongoing ecological processes. The area is well known for its wide assortment of fauna, such as 260 bird species, including the Bengal tiger and other threatened species like the estuarine crocodile and the Indian python.

Eco-geography, rivers and watercourses

Seven chief rivers and countless watercourses form a community of channels in this estuarine delta. Each of the rivers possess a southward course towards the sea. The eco-geography of the region is totally dependent on the tidal impact of 2 circulation tides ebb tides happening within 24 hours using a tidal variety of 3–5 and up to 8 m at ordinary spring wave, inundating the entire of Sundarban in varying depths. The tidal action deposits silts back to the stations and increasing the mattress, it forms new islands and creeks leading to cloudy geomorphology.

There’s an excellent all-natural depression known as the Swatch of No Ground in the Bay of Bengal between to 21°22′ latitude at which the thickness of water varies abruptly from 20 m to 500 m.

This mysterious melancholy pushes back the silts towards south or further east to make new islands.

The Sundarbans Inscripted as UNESCO World Heritage Site

The inscription of the Sundarbans in Bangladesh as a UNESCO World Heritage Site on 7 December 1997 is a manifestation of the importance of the area’s unique ecosystem. The Sundarbans Reserve Forest (SRF), located in the south-west of Bangladesh between the river Baleswar in the East and the Harinbanga in the West, adjoining to the Bay of Bengal, is home to one of the biggest mangrove forests on the planet, using a rich diversity of both terrestrial and aquatic fauna and flora. The Sundarbans is not just ecologically important: countless individuals also rely on the Sundarban Delta for their livelihood, if it be for timber, sustenance fishing, or gathering. The site also serves as a guardian belt to guard the folks from weather issues. Shrimp farming became an attractive choice to create easy money from the early 1980s, and since then thousands of hectares of the Sundarbans were converted into shrimp ponds. As a result of this, the woods has been decimated: large tracts of forests were converted to areas acceptable for shrimp farming, fishermen make a lot of by-catch, and there’s been a growth in saline intrusion as well as flooding vulnerability on account of the elimination of mangroves.

Sundarbans Mangroves

The Sundarbans Mangroves ecoregion on the shore forms the seaward fringe of their delta and is the world’s largest mangrove ecosystem, using 20,400 square kilometres (7,900 sq mi) of an area covered. The dominant mangrove species Heritiera fomes is known as sundri or sundari. Mangrove forests are not home to a great variety of plants. They have a thick ribbon, as well as the undergrowth is mostly seedlings of these mangrove trees. Aside from the sundari, other tree species in the forest include Avicennia Xylocarpus mekongensis Xylocarpus granatum Sonneratia apetala Bruguiera gymnorhiza Ceriops decandra Aegiceras corniculatum Rhizophora mucronata Nypa fruticans Twenty-six of the fifty broad mangrove species found on earth grow nicely in the Sundarbans. The commonly identifiable vegetation types in the dense Sundarbans mangrove woods are warm water mixed forest, mangrove scrub, brackish water combined woods, littoral forest, wet woods and moist alluvial grass forests. The Bangladesh mangrove plant of the Sundarbans differs greatly from other non-deltaic coastal mangrove forests and upland forests institutions. Unlike the former, the Rhizophoraceae are of small importance.
