Bardia National Park is the largest and most undisturbed area in the Terai region. Having resettled the 1500 people that used to reside in this 968 square kilometers land, this park is the largest and most undisturbed wild area in Southern Nepal. Densely covered by Sal forests with a mixture of grassland, savannah and riverine forests, the farmland has been replaced by natural vegetation creating an excellent habitat for endangered animals like rhinoceros, wild elephant, tiger, swamp deer, black buck, gharial crocodile, and gangetic dolphin.
Filling the wide air with about 200 species of resident and migrating birds, Bengal Florican, Lesser Florican Silver Eared Mesia and Sarus Crane are from the endangered list. There are also over 30 different mammals including many reptiles and fishes.
