The Indian one-horned rhinoceros is one of the precious gems of Indian wildlife. This one-horned rhinoceros is native to parts of India and Nepal. In the ancient times, Rhinoceros was present in large number all across India but in present time they are confined to the only state of Assam and other adjoining areas. The Indian one-horned rhinoceros is the second largest rhinoceros in the world. The sighting of one horned rhinoceros is very common in the Kaziranga National Park which has given a very essential contribution in their conservation. Due to the ancient belief in the healing and magical powers of their horn, poaching has become highly prevalent which has led to the decrease in their population. IUCN has declared them to be endangered and after this the Government of India has accelerated the conservation process of one horned rhinoceros.

Poaching has been the major threat to one horned rhinoceros. They are generally poached for their horns used in traditional Chinese medicine. Shooting, electrocution, poisoning, use of noose are some of the heinous ways in which this animal has been obliterated from Indian forests. Their major population is generally concentrated in Kaziranga National Park due to which they are more prone to endemic disease, natural disasters and inbreeding depression.
