where researchers can land and travel to Aldabra. In common with about half the other islands of
Seychelles, the Aldabra Islands are volcanic in origin. They were created by an uplift process where part or
all of a reef system may become land as a result of crustal movements raising it above sea level. Mangrove
forests are found on the islands. The Aldabras were once rich in guano (deposits formed from bird
droppings), but it was almost all collected and sold for fertilizer in the early 1950s. It is now famous for its
giant tortoises, and a nature reserve established in 1976 completely protects them and other animals. The
Aldabras were designated a World Heritage Site in 1982. The islands were uninhabited in the late 20th
century. Tortoises are found in both the Old World and the New, but the majority of the 40-odd living
species are confined to Africa and Madagascar. Of the giant tortoises native to about 30 islands in the
Indian Ocean, all are extinct except the group native to South Aldabra Island. Giant tortoises attain very
large sizes relative to most other living turtles. One captive Gal pagos tortoise had a shell length (measured
along the curve) of about 1.3 m (4.25 feet) and a weight of about 140 kg (300 pounds). Weights of about
180 kg have been recorded for specimens from Santa Cruz Island.
