The atoll has distinctive fauna including the largest population of giant tortoises ( Aldabrachelys gigantea ) in the world (100,000 animals). Tortoise size varies substantially across

1576-543: A feasibility study to eradicate rats from the atoll has been undertaken. Until recently, Aldabra had remained free of invasive birds. However, the Madagascar fody ( Foudia madagascariensis ) has spread to Aldabra after being introduction to Assumption Island. An eradication program for this bird on both Assumption and Aldabra is almost complete. Due to the limited space of its habitat, extreme weather conditions, epidemic and limited range could also pose serious threats to

1773-425: A food source for the villagers (about 200) living there. Ship rats were inadvertently introduced and recorded before 1870, and house geckos were noted from the 1970s. Sailors landed on the atoll in the 19th century and captured tortoises as food; in 1842, two ships were reported to have taken 1200 of them. By 1900, the tortoises were nearly extinct, and a crew would often have to hunt for three days to find one. In

4925-577: A unique spectacle of natural phenomena; Criterion (ix): The atoll is a superlative example of an oceanic island ecosystem in which evolutionary processes are active within a rich biota. The size and morphological diversity of the atoll has permitted the development of a variety of discrete insular communities with a high incidence of endemicity among the constituent species that are typical of island ecosystems. The natural processes take place with minimal human interference and can be clearly demonstrated in their full complexity; and Criterion (x): Aldabra provides

5122-528: Is accessible primarily through guided tours. The name Aldabra, originally Al-Hadra or Al-Khadra (with several variants), was given by Arab seafarers for "the atoll’s harsh, sun-baked environment"; this name was included in the Portuguese maps of the 16th century. The islands were already known to the Persians and Arabs , from whom they got their name. They had named the Indian Ocean as Bahr-el zanj. It

5319-413: Is encircled by fringing coral reef. Around the rim of the lagoon are the larger islands of the atoll. The total land area of the atoll is 155.4 square kilometres (60.0 sq mi). The size including the lagoon is 380 square kilometres (150 sq mi). The outside rim of the atoll has three passages which connect to the lagoon, which is 6–10 kilometres (3.7–6.2 mi) in width where it opens to

5516-419: Is illustrated by the remnants of a crushing mill at Picard Island , which was used to crush bones of tortoises, which were also brought in from other islands in the atoll. Efforts made to grow plantation crops of coconuts, cotton, and sisal failed due to inadequate water sources on the atoll; relics of these plantations are still found on some of the islands. In the late 19th century, goats were introduced as

The mangroves, which thrive in tidal mudflat areas and saline conditions, are seen on the shores of the lagoon and are integral to the coastal ecosystem. There are seven species of mangrove on Aldabra, three of which are rarely occurring species. These include 'Mangliye blan' or white mangrove ( Avicennia marina ) which grows to 12 metres (39 ft), 'Mangliye lat' or black mangrove ( Bruguiera gymnorhiza ) which grows to 18 metres (59 ft) in
