The Terai is a stretch of lowlands in the southernmost part of Nepal. Often described as the rice bowl of the country, the region supports one of the most spectacular assemblages of large mammals in Asia such as the Bengal Tiger, the Greater One-Horned Rhinoceros, the common leopard, Asian elephant, and more. The protected areas of the Terai are also an important foothold for several of Asia's birds, reptiles, and freshwater fish, as well as several types of sal, riverine and mixed forests and grasslands. The ecosystem services provided by the region plays a major role in supporting the socioeconomic well-being and development of people in the Terai and extended Churia regions of Nepal.
Located in the shadows of the Himalayas, the trans-boundary Terai Arc belt stretches from Nepal’s Bagmati River in the east to India’s Yamuna River in the west, connecting 16 protected areas across both countries. In Nepal, the Terai Arc Landscape (TAL) covers a vast area of 24,710 sq. km with a network of six protected areas, forests, agricultural lands and wetlands, with over six million people depending on its forests for food, fuel, and medicine.
