The plains of Nepal are known as the Tarai and they occupy 17% of the land, stretching from the far-west to the far-east covering the entire southern part of the country. The lowest altitude in this region is known to be 70m above sea level. With a sub-tropical climate, the land here is exceedingly fertile and produces the bulk of the food grains for the country’s population. Economically, Terai is the most productive region of Nepal. The majority of the major industries in Nepal are in this region. Agriculture is the main economic stake of the region.. Main crops are paddy, wheat, pulses, moong, sugarcane, jute, tobacco, and maize. Many agro-based industries like jute factories, sugar mills, rice mills and tobacco factories are established throughout the region.
Along this belt lie the Chitwan National Park, Bardia National Park, Shukla Phanta Wildlife Reserve and the Koshi Tappu Wildlife Reserve which harbour an amazing variety of wildlife including endangered species such as the elusive Royal Bengal tiger, the One-horned rhinoceros and Gangetic dolphins along with rare species of birds.
