when did the western black rhino become extinct?
by the 1930s
for most of the 20th century the continental black rhino was the most numerous of all rhino species. around 1900 there were probably several hundred thousand living in africa. during the latter half of the 20th century their numbers were severely reduced from an estimated 70,000 in the late 1960s to only 10,000 to 15,000 in 1981. in the early 1990s the number dipped below 2,500, and in 2004 it was reported that only 2,410 black rhinos remained. according to the international rhino foundation—housed in yulee, florida at white oak conservation, which breeds black rhinos—the total african population had recovered to 4,240 by 2008 (which suggests that the 2004 number was low). in 1992, nine rhinos were brought from chete national park, zimbabwe to australia via cocos island. after the natural deaths of the males in the group, four males were brought in from united states and have since adapted well to captivity and new climate. calves and some subadults are preyed on by lions, but predation is rarely taken into account in managing the black rhinoceros. this is a major flaw because predation should be considered when attributing cause to the poor performance of the black rhinoceros population. in 2002 only ten western black rhinos remained in cameroon, and in 2006 intensive surveys across its putative range failed to locate any, leading to fears that this subspecies had become extinct. in 2011 the iucn declared the western black rhino extinct.. there was a conservation effort in which black rhinos were translocated, but their population did not improve, as they did not like to be in an unfamiliar habitat.

the black rhino, of which the western black rhinoceros is a subspecies, was most commonly located in several countries towards the southeast region of the continent of africa. the native countries of the black rhino included: angola, kenya, mozambique, namibia, south africa, united republic of tanzania, zimbabwe, ethiopia, cameroon, chad, rwanda, botswana, malawi, swaziland, and zambia. there were several subspecies found in the western and southern countries of tanzania through zambia, zimbabwe and mozambique, to the northern and north-western and north-eastern parts of south africa. the black rhino's most abundant population was found in south africa and zimbabwe, with a smaller population found in southern tanzania. the western subspecies of the black rhino was last recorded in cameroon but is now considered to be extinct. however, other subspecies were introduced again into botswana, malawi, swaziland and zambia.
