Terai-Duar savanna and grasslands

The Terai-Duar savanna and grasslands is a narrow lowland ecoregion at the base of the Himalayas, about wide, and a continuation of the Gangetic Plain. It is colloquially called Terai in the Ganges Basin east to Nepal, then Dooars in West Bengal, Bangladesh, Bhutan and Assam east to the Brahmaputra River. The world's tallest grasslands are found in this ecoregion, which are the most threatened and rare worldwide.
