Sanjay Gandhi National Park
The Sanjay Gandhi National Park area has a long written history dating back to the 4th century BCE. In ancient India, Sopara and Kalyan were two ports in the vicinity that traded with ancient civilisations such as Greece and Mesopotamia. The land route between these two ports was partially through this forest.
Sundarbans
The Sundarban National Park is a National Park, Tiger Reserve, and a Biosphere Reserve in West Bengal, India. It is part of the Sundarbans on the Ganges Delta, and adjacent to the Sundarbans Reserve Forest in 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 Sundarbans National Park was declared as the core area of Sundarbans Tiger Reserve in 1973 and a wildlife sanctuary in 1977. On 4 May 1984 it was declared a National Park.
