Named after the endangered Sundari mangrove trees found here, the Sundarbans are a massive forested area reaching from Bangladesh into India. The Sundarbans are the largest mangrove forest in the world supporting over eighty species of salt-tolerant mangrove plant species. This incredibly diverse mangrove forest is so large and remote that it provides habitat for the threatened Bengal tiger. An estimated 350 individuals roam in the tangle of mangrove roots and silty soils. The Indian core area, called the Sundarbans National Park, was designated as a World Heritage site in 1987, and the three Wildlife Sanctuaries protecting the Sundarbans in Bangladesh were inscribed in 1997. The Sundarbans are immensely rich in mangrove flora and mangrove-associated fauna and while tigers can be challenging to spot, other wildlife species are present including macaques, Indian grey mongoose, leopard cats, sea turtles, wild boars, jungle cats, flying foxes, and spotted deers (Chital).
