Most Attraction of Bangladesh, The Sundarbans National Park

The Sundarbans National Park (Bengali: সুন্দরবন জাতীয় উদ্যান Shundorbôn Jatio Uddan)
is a National Park, Tiger Reserve, UNESCO World Heritage Site and a
Biosphere Reserve located in the Sundarbans delta in the Indian state
of West Bengal. This region 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.In 1911, it was described as a tract of waste country which
had never been surveyed, nor had the census been extended to it. It then
stretched for about 165 miles (266 km) from the mouth of the Hugli to the
mouth of the Meghna, and was bordered inland by the three settled
districts of the Twenty-four Parganas, Khulna and Backergunje. The total
area (including water) was estimated at 6,526 square miles (16,902 km2).
The present Sundarbans National Park was declared as the core area of
Sundarbans Tiger Reserve in 1973 and a wildlife sanctuary in 1977.
On May 4, 1984 it was declared a National Park. It was inscribed on the
UNESCO World Heritage list in 1987.[1] Whole Sundarbans area was declared
as Biosphere Reserve in 1989.
