The Terai or Tarai is a region of northern India and southern Nepal. The Terai is a strip of natural marshland bordering the Yamuna River to the west and the Brahmaputra River to the east. To the north of the Terai are the Himalayas. The marshy areas have been reduced by drainage and cultivation.[1]
