The Indian rhinoceros is the biggest of the three rhinos of Asia, and, along with the African white rhino, is the biggest of all rhino species. Its single black horn identifies it, along with its gray-brown hide and skin folds, giving it an armor-plated look. This species is a conservation success, as its numbers have increased significantly since 1975. At that time there were just 600 rhinos remaining in the wild. Following decades of successful efforts, numbers increased to 3,500 in Nepal and India by mid-2015. Now it is the most numerous out of the three rhino species in Asia.

Found throughout the subcontinent of northern India in the past, the Indian rhinoceros now lives only in dispersed populations in Nepal and India. It prefers to live on floodplain grasslands but is sometimes found in adjacent forests and swamps. Its habitat is surrounded by human-dominated landscapes so that in many areas, this species occurs in cultivated areas, and pastures.
The Indian rhino is generally solitary, except when females are with their young. Loosely connected groups of a few individuals occur, especially in foraging areas or wallowing grounds. They feed mostly in the cool of the early morning, during the late afternoon, or at night. During the day, they spend a lot of time in water or wallowing in the mud in order to keep cool. Males have loosely defined territories that they do not defend well, and often such territories overlap. Occasionally there are aggressive interactions between rhino, with charges and horn clashes. Such fighting between males often causes death when the population numbers are high. Rhinos are known to make about 10 sounds, including snorts, honks and roars. Scent deposition is common, with large communal dung heaps often being formed.
Indian rhinos are herbivores, they eat grass, leaves, fruit, branches, and aquatic plants, as well as cultivated crops. They prefer tall reedy grasses to short species. They drink daily and are fond of mineral licks.
Little information is known about the mating system of Indian rhinos. Only dominant bulls will mate with females, and it is thought that scent is a means of assessing them. This may suggest that Indian rhinos exhibit a polygynous mating system. Breeding takes place throughout the year. After a gestation of 480 days, a single young is born, with a weight of 70 kg. Weaning usually takes place after one year, although it can last for 18 months. The offspring stays with its mother until her next calf is born, usually in 3 years’ time. One week before a subsequent birth, the mother will chase the previously born calf away. Females are sexually mature at 9 years old for males, and 4 years old for females.
In the past, hunting was largely responsible for the Indian rhino decline. During the 20th century, both Europeans and Asians hunted rhinos for sport. They were also killed in tea plantations as agricultural pests. Poaching remains their biggest threat, driven by increased demand for rhino horns, especially among the growing middle class of Asia. Indian rhinos also suffer from the loss of their habitat. Today, the demand for land by the increasing human population threatens this species. Many protected areas for rhinos have reached the limit of numbers they can support, which causes human-rhino conflict because rhinos leave the protected areas seeking food in the surrounding villages.
According to the WWF Panda resource, the total population size of the Indian rhino today is around 3,500 individuals. According to the World Wildlife (WWF) resource, the total population size of the Indian rhino is over 3,000 individuals. Currently, this species is classified as Vulnerable (VU) on the IUCN Red List. However, its numbers today are increasing.
