The Western Black Rhino of Africa has been declared officially extinct, and two other subspecies of rhinoceros are close to meeting the same fate, a leading conservation group said Thursday.
The International Union for Conservation of Nature said a recent reassessment of the Western Black Rhino had led it to declare the species extinct, adding that the Northern White Rhino of central Africa is now "possibly extinct" in the wild and the Javan Rhino is "probably extinct" in Vietnam, after poachers killed the last animal there in 2010.
A small but declining population of the Javan Rhino survives on the Indonesian island of Java, it added.
About a quarter of all mammals are at risk of extinction, IUCN said, adding that some species have been brought back from the brink with successful conservation programs.
