What is the Inner Tarai region of Nepal?

The Inner Tarai is a series of broad, elevated basins located in Nepal between the Churia Range to the south and the Mahābhārat Range to the north.1

These basins typically measure about 10 miles in width and range from 20 to 40 miles in length, with elevations between 2,000 and 3,000 feet. Historically, these areas were covered in forests and savanna grass; however, in many locations, the land has been cleared to provide timber and to create space for agricultural cultivation. The Inner Tarai is distinct from the Tarai, which is the low, flat, and fertile plain situated further south along the border with India.1
