The ranch was converted into a wildlife conservancy and was transferred from FFI to a Kenyan non-profit entity in 2005 under a long-term management agreement. In 2003, with the help of the Arcus Foundation, FFI purchased a 364-km 2 cattle ranch that forms part of a critical wildlife corridor at the foot of Mount Kenya. Could this subspecies be brought back from extinction? The future is uncertain and it is a race against time. Rhino experts are now exploring the possibility of artificial reproduction technologies, using in vitro fertilisation and southern white rhino surrogates as a way to preserve and maintain northern white rhino genes into the future. Even before his sad and widely publicised death in March 2018, Sudan’s old age meant that natural reproduction was no longer an option. In 2013, one of the males suddenly died from a heart attack leaving just one male (Sudan) and two females in Ol Pejeta Conservancy. Sadly, despite a number of matings, no rhino calves were born. It was hoped that a more natural environment would stimulate them to breed. In December 2009, with support from Fauna & Flora International (FFI), the last four breeding individuals (two males and two females) were flown from the zoo to Kenya’s Ol Pejeta Conservancy in a final attempt to save the subspecies from extinction. This left just eight northern white rhinos in two zoos on opposite sides of the world – in the Czech Republic and California.Īttention quickly turned to the northern white rhinos living in Dvůr Králové Zoo in Czech Republic. In 2008, a survey in Garamba concluded that northern white rhinos had become extinct in the wild. However, political instability in these countries and growing demand for rhino horn led to an increase in poaching.Īrmed conflict across Central Africa in the 1970s and early 1980s wiped out most of the remaining northern white rhinos except for a small population in Garamba National Park in DRC.

This illustration shows a paleoartist’s reconstruction of the three extinct rhinoceros species whose genomes were sequenced as part of the study.Northern white rhinos once ranged across north-western Uganda, southern Chad, south-western Sudan, the eastern part of Central African Republic and north-eastern Democratic Republic of Congo (DRC). In the foreground is a Siberian unicorn ( Elasmotherium sibiricum), and close behind are two Merck’s rhinoceroses ( Stephanorhinus kirchbergensis). In the far background is a woolly rhinoceros ( Coelodonta antiquitatis). There’s been an age-old question going back to Darwin’s time about the relationships among the world’s five living rhinoceros species. One reason answers have been hard to come by is that most rhinos went extinct before the Pleistocene. Now, researchers reporting in the journal Cell on August 24 have helped to fill the gaps in the rhino evolutionary family tree by analyzing genomes of all five living species together with the genomes of three ancient and extinct species.

The findings show that the oldest split separated African and Eurasian lineages about 16 million year ago.

They also find that-while dwindling populations of rhinos today have lower genetic diversity and more inbreeding than they did in the past-rhinoceroses have historically had low levels of genetic diversity.
