At the foot of the Himalayas Chitwan is one of the few remaining undisturbed vestiges of the Terrai region, which formerly extended over the foothills of India and Nepal. It particularly has rich flora and fauna and one of the last population of single horned Asiatic rhinoceros dwell freely in this park and it is also one of the last refuge of the magnificent Royal Bengal Tiger. Surrounding Chitwan National Park in southern Nepal is one of the best planned and most intelligently developed tourist areas of Nepal. Though the Terrai is certainly not what it once was the preserved portion within the Chitwan National Park is still a treat for animal lovers the Royal Bengal Tigers roam the region, the one horned rhinoceros can be seen charging through the under bush, feeding and even courting the Rapti river has been dammed to form a man-made lake called Lamital where aquatic birds, kingfishers, woodpeckers and marsh muggers can be seen in abundance. Elephant grass five to six feet tall provide excellent camouflage for the animals, the grass also serves as food for the gaur (local bison) rhino and other herbivores. Once a year local people are allowed into the park area to cut grass, the grass also stored as food for the domestic animals during dry seasons, it is also dried and used to thatch roofs.
