The Sundarbans, the world’s largest mangrove forest, covers 10,000 square kilometers of the world’s biggest delta, where the Ganges, Brahmaputra, and Meghna rivers discharge into the Bay of Bengal. The forest is home to an array of wildlife including Bengal tigers, estuarine crocodiles, and monitor lizards.
Tourists visiting the Sundarbans embark on guided wildlife cruises, exploring the area’s labyrinthine tidal waterways, mudflats, and silt islands. Their adventures typically include walks through the mangroves to beaches like Kotka Beach, and journeys on smaller wooden boats that give access to the forest’s narrow waterways. The experience offers not only awe at the might of the wild environment, but also an awareness of its fragility.
A notable aspect of the Sundarbans ecosystem is its shift between states. Approximately one-third of the land disappears and reappears daily due to dramatic tides. The region’s ever-changing nature is heightened by the regular creation and subsequent washing away of silt islands.
In the Sundarbans, wildlife and human residents alike have adapted to live in this constantly transforming environment. Mangroves, such as the locally named Sundari, have developed complex salt-filtration systems and roots that can withstand saltwater immersion and wave action, making them crucial protectors against erosion, storm surges, tsunamis, and vital habitats for a range of organisms.
However, despite parts of the Sundarbans being designated as UNESCO World Heritage Sites, this vital ecosystem is under threat. Rising sea levels, increasing water salinity, habitat destruction due to human activity, and poaching pose significant challenges to the survival of this unique environment.
To counteract these challenges, initiatives like the Karamjal Wildlife Breeding Centre, supported by the Bangladeshi government, are working towards the reintroduction of estuarine crocodiles, tortoises, and deer. Yet, as extreme weather becomes more frequent due to climate change, the threat to the Sundarbans continues to grow.
Visiting the Sundarbans is an adventure filled with wildlife sightings, mingling with locals, and enjoying traditional Bengali games and food. Yet, it’s also a stark reminder of the delicate balance of our ecosystems and the urgent need to protect them.
