However, the Aldabra coral reef has currently been protected against Human influence when having been declared a World Heritage web site, and is home to some 152,000 Aldabra big Tortoises, the world's largest population of the animal. Another isolated population of the Aldabra tortoise resides on the island of Zanzibar, and alternative captive populations exist in conservation parks in Mauritius and Rodrigues. The captive breeding programmes on these islands ar to undertake and revive the species, and populations on them these days seem to be thriving.
