These are- Ganga, Brahmaputra, and Meghna. The Sundarban National Park is the largest sanctuary which is situated on the banks of and delta.
It lies on the Ganges-Brahmaputra Delta at the point where it merges with the bay of bengal. With its array of trees and wildlife the forest is a showpiece of natural history. It is also a centre of economic activities, such as extraction of timber, fishing and collection of honey.
The forest consists of about islands, separated by about interconnected tidal rivers, creeks and canals. The Sundarbans was originally measured about years ago to be of about 16, sq km. It is now estimated to be about 6, sq km, of which about 1, sq km is occupied by waterbodies.
The forest lies under two forest divisions, and four administrative ranges viz Chandpai, Sarankhola, Khulna and Burigoalini and has 16 forest stations. It is further divided into 55 compartments and 9 blocks. The Sundarbans was declared as a Reserve Forest in These wildlife sanctuaries were established in under the Bangladesh Wildlife Preservation Amendment Act, The Bangla word ban means forest, and the name Sundarban was coined either from the forests of Sundari tree ie Sundari-ban, or from the forests of the samudra sea ie, Samudra-ban, or from its association with the primitive tribe Chandra-bandhe which was corrupted into Sundarban.
The generally accepted explanation, however, is its derivation from the sundari tree, the most common tree in these forests.
Geology The tract of the Sundarbans is of recent origin, raised by the deposition of sediments formed due to soil erosion in the Himalayas. The process has been accelerated by tides from the sea face.
The substratum consists mainly of Quaternary Era sediments, sand and silt mixed with marine salt deposits and clay. Geologists have detected a southeastern slope and tilting of the Bengal basin during the Tertiary.
Because of neo-tectonic movements during the 10thth century AD, the Bengal Basin titled eastward. Evidence from borehole studies indicate that while the westernside of the Sundarbans is relatively stable, the southeastern corner is an active sedimentary area and is subsiding.
Soil Soils of the Sundarbans mangrove forest differ from other inland soils in that they are subjected to the effects of salinity and waterlogging, which naturally affect the vegetation. In places soils are semi-solid and poorly consolidated.
The pH ranges widely from 5. Although the Sundarbans soil is in general medium textured, sandy loam, silt loam or clay loam, the grain size distribution is highly variable. Silt loam is dominant textural class.
Sodium and calcium contents of the soil vary from 5. The available potassium content of the soil is low, 0.
Soil salinity increases from east slight to moderate to west highly salinebut the salinity is not uniform from north to south throughout the forest. A Sundarbans stream Climate Since the forest is located on the south of the Tropic of Cancer and bounded by the northern limits of the Bay of Bengal, it is classified as tropical moist forest.
The temperatures in the Sundarbans are fairly equable than those of the adjacent land areas. High temperatures occur from mid-March to mid-June and low in December and January. The mean maximum temperature for the hottest months has been recorded as Humidity is highest in June-October and lowest in February.
Annual rainfall in the Sundarbans is in the range of mm, rainfall increases from west to the east. Most rainfall occurs during the monsoon from May to October. Frequent and heavy showers occur from mid-June to mid-September.
Often storm accompanied by tidal waves result widespread inundation and cause damage to vegetation and animal life.This is the first part of the from the collection of important chapters from Old NCERT for Ancient India's history culture topic for UPSC civil service exam.
Sundarbans play a significant role for supporting wide range of floral and faunal biodiversity and ecosystem services that support livelihoods of local communities. Most of the communities in buffer zone of Sundarbans are depends on Sundarbans resources for their livelihoods.
The Sundarbans (Bengali: সুন্দরবন Shundorbôn [ˈʃundorbɔn] lit. "The beautiful forest") is a vast forest in the coastal region of the Bay of regardbouddhiste.comd in the delta region of Padma, Meghna and Brahmaputra river basins, this unique forest extends across Khulna, Satkhira, Bagerhat districts of Bangladesh and South 24 Parganas, North 24 Parganas districts of West Bengal, regardbouddhiste.comt city: Khulna, Satkhira, Bagerhat, Kolkata, Canning.
Place of Interest: Sundarbans Sundarban is located at about km in west of Dhaka.
Here in the south, spread over an area of about sq. km. of delta swamps along the coastal belt of Khulna is the biggest mangrove forest, Sundarbans (beautiful forest) - the home of the Royal Bengal Tiger. The Sundarbans National Park is a National Park, Tiger Reserve, and a Biosphere Reserve located in the Sundarbans delta in the Indian state of West Bengal.
This region is densely covered by mangrove forests, and is one of the largest reserves for the Bengal tiger.
The Sundarbans is the single largest mangrove forest in the world located in the southern part of Bangladesh sharing one-third part with India. It has been declared as a UNESCO world heritage site in and designated a Ramsar site in
