The 932 square kilometer Royal Chitwan National Park, located in South Central Asia is a protected park that conserves hundreds of species of plants, birds, insects, reptiles, and mammals including the Rhinoceros Unicornis. Conservationists at the national park have no explanation for the appearance of non-native species of weeds and plants that are destroying grasslands. The non-native species are quickly spreading and killing off native grasslands. Research is being commenced to find answers to their appearance and a solution to control the growth of the destructive plants. Time is a critical factor in finding a solution. If destruction of grasslands in the park continues, the rhinos may leave in search of food. Outside of the park, the rhinos face a real threat from poachers. With the few numbers of these rare rhinoceroses left, the death of even one can be detrimental to the survival of the species.
