The West African Black Rhinoceros or Western Black Rhinoceros (Diceros bicornis longipes) is declared extinct by International Union for Conservation of Nature (IUCN) after a recent survey failed to spot any individuals. As per the global assessment by IUCN there are no Wild Black Rhinos remaining in West Africa.
The West African Black Rhinoceros once widespread in the savanna of central-west Africa but declined from poaching. According to IUCN a subspecies of white rhino in central Africa is also listed as possibly extinct.
The IUCN reports that despite conservation efforts, 25% of the world’s mammals are at risk of extinction. As part of its latest work it has reassessed several rhinoceros groups.
