The Javan rhinoceros, Javan rhino, Sunda rhinoceros or lesser one-horned rhinoceros is a critically endangered member of the genus Rhinoceros, of the rhinoceros family, Rhinocerotidae, and one of the five remaining extant rhinoceros species across South Asia and Africa. The Javan rhinoceros is one of the smallest rhinoceros species, along with the Sumatran, or "hairy", rhinoceros. They are superficially similar to Indian one-horned rhinos, as they have plate-like, "armored" protective skin folds, but are slightly smaller in size, at just 3.1–3.2 m (10–10 ft) long and 1.4–1.7 m (4.6–5.6 ft) tall, on average. The heaviest specimens weigh around 2,300 kg/2.3 tonnes, similar to an African black rhinoceros. However, unlike the long and potentially lethal horns of the black or white rhinoceroses of Africa, the Javan species' single, somewhat blunted horn is usually shorter than 25 cm (9.8 in).
Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. Species that may be eligible for reintroduction are typically threatened or endangered in the wild. However, reintroduction of a species can also be for pest control; for example, wolves being reintroduced to a wild area to curb an overpopulation of deer. Because reintroduction may involve returning native species to localities where they had been extirpated, some prefer the term "reestablishment".
The Sumatran rhinoceros, also known as the Sumatran rhino, hairy rhinoceros or Asian two-horned rhinoceros, is a rare member of the family Rhinocerotidae and one of five extant species of rhinoceros; it is the only extant species of the genus Dicerorhinus. It is the smallest rhinoceros, although it is still a large mammal; it stands 112–145 cm (44–57 in) high at the shoulder, with a head-and-body length of 2.36–3.18 m and a tail of 35–70 cm (14–28 in). The weight is reported to range from 500–1,000 kg (1,100–2,200 lb), averaging 700–800 kg (1,540–1,760 lb). Like both African species, it has two horns; the larger is the nasal horn, typically 15–25 cm (5.9–9.8 in), while the other horn is typically a stub. A coat of reddish-brown hair covers most of the Sumatran rhino's body.
Kaziranga National Park is a national park in the Golaghat and Nagaon districts of the state of Assam, India. The park, which hosts two-thirds of the world's Indian rhinoceroses, is a UNESCO World Heritage Site. According to the census held in March 2018 which was jointly conducted by the Forest Department of the Government of Assam and some recognized wildlife NGOs, the rhino population in Kaziranga National Park is 2,613. It comprises 1,641 adult rhinos ; 387 sub-adults ; and 385 calves.
A rhinoceros, commonly abbreviated to rhino, is a member of any of the five extant species of odd-toed ungulates in the family Rhinocerotidae; it can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea. Two of the extant species are native to Africa, and three to South and Southeast Asia.
The Indian rhinoceros, or Indian rhino for short, also known as the greater one-horned rhinoceros or great Indian rhinoceros, is a rhinoceros species native to the Indian subcontinent. It is listed as Vulnerable on the IUCN Red List, as populations are fragmented and restricted to less than 20,000 km2 (7,700 sq mi). Moreover, the extent and quality of the rhino's most important habitat, the alluvial Terai-Duar savanna and grasslands and riverine forest, is considered to be in decline due to human and livestock encroachment. As of August 2018, the global population was estimated to comprise 3,588 individuals, including 2,939 individuals in India and 649 in Nepal. Kaziranga National Park alone had an estimated population of 2,048 rhinos in 2009. Pobitora Wildlife Sanctuary in Assam has the highest density of Indian rhinos in the world with 84 individuals in an area of 38.80 km2 (14.98 sq mi) in 2009.
Dicerorhinus is a genus of the family Rhinocerotidae, consisting of a single extant species, the two-horned Sumatran rhinoceros, and several extinct species. The genus likely originated in the Mid to Late Pliocene of Northern Indochina and South China. Many species previously placed in this genus probably belong elsewhere.
Orang National Park is a national park in India located on the northern bank of the Brahmaputra River in the Darrang and Sonitpur districts of Assam. It covers an area of 79.28 km2 (30.61 sq mi). It was established as a sanctuary in 1985 and declared a national park on 13 April 1999. It is rich in flora and fauna, including great Indian rhinoceros, pygmy hog, Asian elephant, wild water buffalo and the Bengal tiger. It is the only stronghold of the rhinoceros on the north bank of the Brahmaputra.
Way Kambas National Park is a national park covering 1,300 km2 (500 sq mi) in Lampung province, southern Sumatra, Indonesia. It consists of swamp forest and lowland rain forest, mostly of secondary growth as result of extensive logging in the 1960s and 1970s. Despite decreasing populations, the park still has a few critically endangered Sumatran tigers, Sumatran elephants and Sumatran rhinoceroses. It also provides excellent birdwatching, with the rare white-winged wood duck among the over 400 species present in the park.
India is home to a large variety of wildlife. It is a biodiversity hotspot with various ecosystems ranging from the Himalayas in the north to the evergreen rain forests in the south, the sands of the west to the marshy mangroves of the east. India lies within the Indomalayan realm and is the home to about 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian, and 6.2% of flowering plant species. India's forests contain about 500 species of mammals and more than 1300 bird species.

Francesco Romano Nardelli is an Italian naturalist who has dedicated his life to the protection and conservation of endangered species. He is also the co-founder, with John Aspinall, of the Sumatran Rhino Project, one of the most important coordinated efforts to save a critically endangered species.
Reserved wild animals are the highest class of protection for animal species in Thailand's wildlife conservation framework. There are currently nineteen designated species, defined by The Wild Animal Conservation and Protection Act B.E. 2562 (2019). The 2019 act replaced the original law from 1992. The law prohibits hunting, breeding, possessing, or trading any of such species, except when done for scientific research with permission from the Permanent Secretary of National Park, Wildlife and Plant Conservation, or breeding and possession by authorised public zoos.

Rhino poaching in Assam is one of the major environmental issues in India which continues in the region of Kaziranga National Park, Manas National Park and some other grasslands of Assam. Indian rhinos inhabited most of the floodplain of the Indogangetic and Brahmaputra riverine tracts and the neighboring foothills.
The Northern Sumatran rhinoceros, also known as Chittagong rhinoceros or northern hairy rhinoceros was the most widespread subspecies of Sumatran rhinoceros, as well as the only known subspecies native to mainland Asia.
The Bornean rhinoceros, also known as the eastern Sumatran rhinoceros or eastern hairy rhinoceros, is one of three subspecies of Sumatran rhinoceros. The subspecies may be functionally extinct, with only one individual, a female named Pahu, surviving in captivity, and held in the state of Sabah. In April 2015, the Malaysian government declared the Bornean rhinoceros to be extinct in the wild in the Malaysian portion of Borneo. However, in March 2016, a young female rhino was captured in East Kalimantan, providing evidence of their continued existence. The International Union for Conservation of Nature (IUCN) classifies the subspecies as critically endangered.
