description Sundarbans Mangrove Forest Overview

The Sundarbans Mangrove Forest is a UNESCO World Heritage Site located on the delta of the Ganges, Brahmaputra, and Meghna rivers in South Asia. It’s the world's largest single block of mangrove forest supporting unique biodiversity including the endangered Bengal tiger and numerous fish, reptile, bird, and invertebrate species. This complex wetland ecosystem provides vital coastal protection and is crucial for researchers, conservationists, and those interested in understanding global ecological processes and wildlife habitats.

help Sundarbans Mangrove Forest FAQ

Where exactly is the Sundarbans and which countries does it span?

The Sundarbans Mangrove Forest spans the delta of the Ganges, Brahmaputra, and Meghna rivers, straddling the border between India (West Bengal) and Bangladesh. The larger portion—roughly 60%—lies in Bangladesh, while the Indian side is designated as Sundarbans National Park. It was inscribed as a UNESCO World Heritage Site in 1987 (India) and 1997 (Bangladesh).

How many Bengal tigers live in the Sundarbans?

The Sundarbans is home to one of the largest remaining populations of wild Bengal tigers, estimated at around 100 on the Indian side and approximately 114 in the Bangladesh portion, based on recent surveys. These tigers are uniquely adapted to swimming in the brackish mangrove waterways. The population is considered endangered due to habitat loss, poaching, and rising sea levels threatening the delta.

Is it safe to visit the Sundarbans and how do you get there?

Tourism is permitted in designated zones with guided boat tours, typically departing from areas like Sajnekhali or Namkhana on the Indian side, or Mongla in Bangladesh. Visitors are not allowed to disembark in the core tiger reserve areas, so tours are conducted from covered boats with armed forest guards. The primary risks are cyclones, which are seasonal, and wildlife encounters, which are minimized by following guide instructions.

What makes the Sundarbans mangrove ecosystem unique compared to other mangrove forests?

The Sundarbans is the world's largest contiguous block of mangrove forest, covering approximately 10,000 square kilometers. It contains a remarkably high diversity of mangrove species—including the distinctive Sundari tree (Heritiera fomes) that gives the forest its name—and serves as a critical buffer against cyclones and tidal surges for millions of people living inland. No other mangrove forest supports such a large apex predator population.
