NORTHERN WHITE RHINOS - Pride & preservation

Roger Highfield reports for the Telegraph on the efforts being made to preserve endangered animals, with the help of zoos and frozen DNA.

And in reference to the Northern White Rhino, the idea of using Southern White Rhinos as surrogate mothers makes a lot of sense....

Once ranging across north-central Africa, wild populations have fallen to as few as four individuals in Garamba National Park in the Democratic Republic of the Congo.

'The species is dying out as we speak, if it has not already,' said Mr Lawrence. 'But there is the means, thanks to modern science, to bring it back.'

Northern White Rhino semen has been frozen and could be used to reintroduce the species, said Mr Lawrence. 'We have their relative, the southern white rhino, and we are looking at the possibility of using them as surrogate mothers,' he added."
