For the first time in 1879 an area of 4690 sq. km was declared as Protected Forests which were subsequently declared as Reserved Forests in 1928 and 1943. In pre independent India, the area was part of the erstwhile Sundarbans Division with its headquarters at Khulna, Bangladesh. After independence an area of 4262 sq. km came under a new Division called as 24 Parganas Division with headquarters at Alipore, Kolkata. It was from this Division that the Sundarban Tiger Reserve was created under Project Tiger scheme on 23.12.73 by the MOEF, Govt. of India. The seasonally flooded Sundarbans freshwater swamp forests lie inland from the mangrove forests on the coastal fringe. The Sundarbans is intersected by a complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests. The interconnected network of waterways makes almost every corner of the forest accessible by boat.
