The 2,585-sq km (998 sq-mile) Sundarbans Reserve, a UNESCO World Heritage Site created within the delta, was declared a Tiger Reserve in 1973 to protect the endangered Royal Bengal tiger. The intricate network of waterways, creeks and alluvial islands abounds in a variety of marine life, including crustaceans and dolphins, as well as reptiles such as Olive Ridley turtles and estuarine crocodiles. The swamps also attract an impressive array of birds, especially waterfowl. Guided boat tours take visitors for leisurely rides through the enchanting mangroves.
Renowned for their variety of mangroves, the Sunderbans were once dominated by the sundari tree (Heritiera fomes), now nearly extinct due to rampant timber poaching. Mangroves have ingeniously adapted to flooding and salinity, using breathing roots or pneumatophores.
Small rowboats, available from Sajnakhal , take visitors along the reserve’s many waterways. Theses craft are preferable to the noisier motorboats that tend to scare away wildlife, especially the rich variety of waterfowl.
