Sundarbans: The Largest Mangrove Forest of The Earth

Forest is the lung of the Mother Earth. Without forest it’s impossible to live in the world. That’s mean no forest no life. The word “forest” comes from old French word forest (also fores). And the Bans word derives from the English Word Forest. The first known forests on Earth arose in the Late Devonian (approximately 380 million years ago), with the evolution of Archaeopteryx.

A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves occur worldwide in the tropics and subtropics, mainly between latitudes 25° N and 25° S. The total mangrove forest area of the world in 2000 was 137,800 square kilometers (53,200 sq mi), spanning 118 countries and territories.

Mangroves are salt-tolerant trees, also called halophytes, and are adapted to life in harsh coastal conditions. They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action. They are adapted to the low oxygen conditions of waterlogged mud. Although mangroves inhabit only 0.7% of global coastal zone, but they have a significant contribution to the global carbon. Primary production by mangroves provides a substantial source of energy for aquatic food webs.

In the coastal area of Bangladesh there are huge natural mangrove forests. Sundarbans is the biggest natural mangrove forest in the world, located between Bangladesh and India. The most beautiful part of the Sundarbans consists of Bangladesh and it is 60%. It is the deepest with the different types of geological periods and fauna. If you want to get a true experience of the mangrove forest, you must visit the Bangladesh side of the Sundarbans.

The Bengali name Sundarban Bengali: Sundarban means “beautiful forest.” It may have been derived from the word Sundari or Sundri, the local name of the mangrove species Heritiera fomes. Alternatively, it has been proposed that the name is a corruption of Samudraban, Shomudrobôn (“Sea Forest”), or Chandra-bandhe, the name of a tribe.

The 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 Emperors leased the forests of the Sundarbans to nearby residents. 

The first Forest Management Division to have jurisdiction over the Sundarbans was established in 1869. In 1875 a large portion of the mangrove forests was declared as reserved forests under the Forest Act, 1865 (Act VIII of 1865). The remaining portions of the forests were declared a reserve forest the following year and the forest, which was so far administered by the civil administration district, was placed under the control of the Forest Department. A Forest Division, which is the basic forest management and administration unit, was created in 1879 with the headquarters in Khulna, Bangladesh. The first management plan was written for the period 1893–98. 

In 1911, it was described as a tract of waste country which had never been surveyed nor had the census been extended to it. It then stretched for about 266 kilometres (165 mi) from the mouth of the Hooghly River to the mouth of the Meghna river and was bordered inland by the three settled districts of the 24 Parganas, Khulna and Bakerganj. The total area (including water) was estimated at 16,900 square kilometres (6,526 sq mi). It was a water-logged jungle, in which tigers and other wild beasts abounded. Attempts at reclamation had not been very successful. The Sundarbans were intersected by river channels and creeks, some of which afforded water communication throughout the Bengal region both for steamboats and ships.

There are several amazing places in Sundarbans, you must not miss. Among the places are Kotka Beach, Jamtola Beach, Karamjol, Hiron Point (Nilkomol), Dublar Char Island, Tin Kona Island, Kochikhali Forest, Mandarbaria.

The Sundarbans is a mangrove area in the delta formed by the confluence of the Ganges, Brahmaputra and Meghna Rivers in the Bay of Bengal. It spans from the Hooghly River in India’s state of West Bengal to the Baleswar River in Bangladesh. It comprises closed and open mangrove forests, agriculturally used land, mudflats and barren land, and is intersected by multiple tidal streams and channels. Four protected areas in the Sundarbans are enlisted as UNESCO World Heritage Sites, viz. Sundarbans National Park, Sundarbans West, Sundarbans South and Sundarbans East Wildlife Sanctuaries. Despite these protections, the Indian Sundarbans were considered endangered in a 2020 assessment under the IUCN Red List of Ecosystems framework.
The Sundarbans mangrove forest covers an area of about 10,000 sq km (3,900 sq mi), of which forests in Bangladesh’s Khulna Division extend over 6,017 sq km (2,323 sq mi) and in West Bengal, they extend over 4,260 sq km (1,640 sq mi). The most abundant tree species are sundari (Heritiera fomes) and gewa (Excoecaria agallocha). The forests provide habitat to 453 faunal wildlife, including 290 bird, 120 fish, 42 mammal, 35 reptile and eight amphibian species.
