Sundarbans: The Largest Mangrove Forest in The World

If you are asked to name some of the places of interest in Bangladesh, then the Sundarbans is one of the first places that will come to your mind. In addition to the unique gathering of animals and birds, including the Royal Bengal Tiger, and its historical significance, the forest has an endless natural beauty that is bound to catch the eye of travelers.


At the mouth of the Padma, Meghna, and Brahmaputra rivers, Khulna, Bagerhat, and Satkhira districts in the south-west of Bangladesh and some parts of India have formed this green land of endless natural beauty. Covering an area of ​​6016 km in Bangladesh and part of India, it stands at about 10,000 sq km. Although the Sundarbans were formed in an uninterrupted area, the country was divided into two parts, one part of which is ‘Sundarbans’ (Bangladesh) and the other part is Sundarbans National Park (India). In other words, the Sundarbans have been included in the UNESCO World Heritage List twice under two different names.

Brief History and Structure

Many believe that the Sundarbans got their name from the forest of the sea (sea-forest) or the indigenous Chandra-dam here. However, the most widely accepted explanation is that the Sundarbans were named after Sundari, the main tree of the Sundarbans.

Not much is known about the origin of the Sundarbans, but it is thought that the erosive silt, sand, and gravel of the Himalayas have created char on the coast by the Padma and Brahmaputra flowing for thousands of years. On the other hand, as it is on the seashore, the char has been soaked in saltwater and silt has accumulated. Over time, a variety of plants have sprung up and mangrove forests have sprung up.

Surveying was not easy in the Sundarbans, which are rich in water bodies and wildlife. When the East India Company took ownership of the Sundarbans in 1757, it was first mapped. At that time the area of ​​the Sundarbans was about 16 thousand square kilometers. After that, as settlements gradually developed in the vicinity of the Sundarbans, their size gradually decreased. The first survey was conducted in 1829 when it was later acquired by the British government. After many ups and downs, the Sundarbans has declared a protected forest in 18 and the responsibility for the following year was handed over to the Forest Department. In this way, after India gained independence in ’47, this treasure of natural beauty was divided into two parts.

Plants and Animals

Compared to other mangrove forest plants in the world, there are significant differences in the vegetation of the Sundarbans. Because not only saltwater but also freshwater flows in the Sundarbans. This feature sets the Sundarbans apart from other mangrove forests worldwide.

The main reason for naming the Sundarbans is its beautiful trees. Needless to say, the most eye-catching plant in this forest is the beautiful tree. Besides, Gewa, Garan, and Keora are the forest divers of the Sundarbans. Since most of the plants here are evergreen, their physiological and structural adaptations are almost the same.

In 1903 David Prain wrote a book on the Sundarbans. There are 334 species of plants of 245 classes in the Sundarbans. And according to the information received so far, 35 out of 50 species of plants in the mangrove forest are found in our Sundarbans. The Sundarbans are also dominated by herbaceous plants characteristic of mangrove forests. Shawn, reed, and Golpata are among them.

The most notable of the diversity is the Royal Bengal Tiger, which inhabits the Sundarbans. The Royal Bengal Tiger is said to be the most handsome of all the tigers in the world.

In the fifties, tigers could be seen roaming almost everywhere in Bangladesh. The last Royal Bengal Tiger was observed in Madhupur and Gazipur in Dhaka in 1986. After that, the number of tigers in Bangladesh gradually decreased. And currently, the only habitat of this tiger is the Sundarbans. However, the number of tigers in the Sundarbans is also decreasing day by day. According to the 2004 census, the number of tigers in the Sundarbans was 440, but a private census in 2006 showed that the number was only 200-250, while the number of tigers in neighboring India was more than 1,400. And according to the latest census of 2015, the number of tigers in Bangladesh is only 106!
