Three of the five species of rhinoceros are listed as critically endangered on the International Union for Conservation of Nature and Natural Resources Red List: the black rhinoceros, the Javan rhinoceros and the Sumatran rhinoceros. The Indian rhinoceros is listed as vulnerable, and the white rhinoceros is listed as threatened.
The Sumatran rhinoceros and the black rhinoceros have experienced population declines of 80 and 97 percent respectively in the roughly 60 years prior to 2014, pushing them to the brink of extinction. The Javan rhinoceros has fewer than 50 mature individuals left and is continuing to experience a decline in population. Poaching with the intention to take trophy horns continues to plague all rhinoceros species.
