i actually had a second look at the newspaper and it specifically mentioned Cameroon so i looked up and found this: (the black rhino has 4 subspecies:the southern, the southwestern, the eastern, and the western. All four subspecies are listed as critically endangered on IUCN's Red List. )

Western black rhino
The western black rhino once ranged throughout the savanna zones of West Africa, but today only a few scattered animals remain in Cameroon. This rarest and most endangered subspecies of black rhino hovered at around eight individuals in 2001 (IUCN).
i found this at WWF worldwildlife.org
