Sundarbans National Park: A Unique Mangrove Ecosystem and Home to Endangered Species

The Sundarbans National Park, spanning over 10,000 square kilometers across the Bay of Bengal, is a unique and vital ecosystem that straddles the border between India and Bangladesh. This vast expanse of interconnected waterways, islands, and mangrove forests forms the world's largest single block of tidal halophytic mangrove forest, making it a globally significant habitat.

UNESCO Description of the World Heritage Site

The Sundarbans covers 10,000 km2 of land and water (more than half of it in India, the rest in Bangladesh) in the Ganges delta. It contains the world's largest area of mangrove forests. A number of rare or endangered species live in the park, including tigers, aquatic mammals, birds and reptiles.

Encyclopedia Record: Sundarbans National Park

Sundarbans National Park is a national park in West Bengal, India, and core part of tiger reserve and biosphere reserve. It is part of the Sundarbans on the Ganges Delta and adjacent to the Sundarban Reserve Forest in Bangladesh. It is located to south-west of Bangladesh. The delta is densely covered by mangrove forests, and is one of the largest reserves for the Bengal tiger. It is also home to a variety of bird, reptile and invertebrate species, including the salt-water crocodile. The present Sundarban National Park was declared as the core area of Sundarban Tiger Reserve in 1973 and a wildlife sanctuary in 1977. On 4 May 1984 it was declared a national park. It is a UNESCO World Heritage Site inscribed in 1987, and it has been designated as a Ramsar site since 2019. It is considered as a World Network of Biosphere Reserve from 10 November 2001.
