There are 5 species of rhino in the world: Black Rhino, White Rhino, Sumatran Rhino, Javan Rhino, and Greater One-Horned Rhino. Three of the five species of rhinos are among the most endangered animals in 2022: the black rhino, the Javan rhino, and the Sumatran rhino. Populations of black rhinos declined dramatically in the 20th century. However, the black rhino is still considered critically endangered. White rhinos are now classified as Near Threatened and around 18,000 animals exist. The recovery of the greater one-horned rhino is a success. Populations have rebounded from fewer than 100 individuals to more than 4,000 today.
Sumatran rhinos are more threatened due to habitat loss and fragmentation. They are now critically endangered, with only five substantial populations in the wild. Fewer than 80 Sumatran rhinos survive in small populations in Indonesia’s Gunung Leuser and Way Kambas National Parks, and a few isolated animals inhabit central Kalimantan. Javan rhinos are found only in Indonesia’s Ujung Kulon National Park (UKNP). Indonesia’s Ministry of Environment and Forestry (MOEF) estimates the Javan rhino
population at 76 individuals in 2022. The species is critically endangered, with only one known population in the wild, and no individuals in captivity.
