The Terai, or plains, of eastern Nepal lie along the Indian border. Much of the land is taken up by rice and jute cultivation, though areas of forest remain in the north where the plains meet the hills. A large amount of the forest was cleared in the last century, and many settlers migrated to the area from the hills and from India, making the area one of the most culturally diverse regions in Nepal.
This region has many rural areas, but also boasts the largest industrial area in the whole country, expanding from the Rani Mills area to the Duhabi River. Biratnagar Jute Mills and Dhanawat Matches are among the nation's oldest industries. Both Biratnagar and Indrapur also have universities.
