A Conservationist carries a darted fallow deer for relocation from Robben Island, off Cape Town, April 24, 2010. About 75 of the non-indigenous deer are being relocated to the Lions Rock sanctuary by the Four Paws (Vier-Pfoten) conservation group. In recent years rabbits, cats and deer have been culled to lessen the negative environmental effects to the island, a World Heritage site where former President Nelson Mandela spent much of his 27 year incarceration.
