What you think about some future captive breeding programme for South-central subspecies of Black rhinoceros, the most numerous subspecies, and that kept in Frankfurt zoo, as only place in Europe with such subspecies? Also what subspecies are the black rhinoceroses in USA, are there South-central black rhinos? As I remember US holds good population of both Eastern and South-central black rhinoceroses? Or I am wrong. And how many individuals of each subspecies? What if South Africa sell some 30 South-central black rhinoceroses to zoos, will they have the capacity to hold all of them; will that easily happen if the price of black rhinos drop as that of southern white rhinos (about 9,000 euros/per animal, aproximately)? Why zoos instead to purchase only Southern white rhinos, whose number is above 250 in Europe, do not purchase some South-central black rhinos (and start managing population), or their export to zoos is banned? I would love to work (keep them good in a zoo) with black rhinoceroses.
