Sundarbans Bangladesh

The Sundarbans (Bengali: সুন্দরবন, Shundorbôn) is a natural region comprising southern Bangladesh and a small part in Eastern India. It is the largest single block of tidal halophytic mangrove forest in the world. The Sundarbans covers approximately 10,000 square kilometres (3,900 sq mi) most of which is in Bangladesh with the remainder in India. The Sundarbans is a UNESCO World Heritage Site.

Sundarbans South, East and West are three protected forests in Bangladesh. This region is densely covered by mangrove forests, and is the largest reserves for the 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. history of the area can be traced back to 200–300 AD. A ruin of a city built by Chand Sadagar has been found in the Baghmara Forest Block.

 During the Mughal period, the Mughal Kings leased the forests of the Sundarbans to nearby residents. Many criminals took refuge in the Sundarbans from the advancing armies of Emperor Akbar. Many have been known to be attacked by tigers. Many of the buildings which were built by them later fell to hands of Portuguese pirates, salt smugglers and dacoits in the 17th century. Evidence of the fact can be traced from the ruins at Netidhopani and other places scattered all over Sundarbans. The legal status of the forests underwent a series of changes, including the distinction of being the first mangrove forest in the world to be brought under scientific management. The area was mapped first in Persian, by the Surveyor General as early as 1764 following soon after proprietary rights were obtained from the Mughal Emperor Alamgir II by the British East India Company in 1757. Systematic management of this forest tract started in the 1860s after the establishment of a Forest Department in the Province of Bengal, in British India. The management was entirely designed to extract whatever treasures were available, but labour and lower management mostly were staffed by locals, as the British had no expertise or adaptation experience in mangrove forests.
The Sundarbans was everywhere intersected by river channels and creeks, some of which afforded water communication throughout the Bengal region both for steamers and for native ships.
