General characteristics

The Granitic Seychelles are in the north-east of a larger archipelago which includes a chain of low-lying coralline islands (see Aldabra, EBA 099). The inner islands were once part of the ancient landmass of Gondwanaland, and are the world's only isolated granite islands, all other oceanic islands being limestone or volcanic. The largest island is Mah

Restricted-range species

The endemic birds are all forest species, and several are able to use secondary forest and plantations. Distribution between islands appears patchy (see 'Distribution patterns table', below) as several of the multi-island species have become extinct on at least one island (although some have been reintroduced). Today only two species are confined to single islands: Otus insularis on Mah

Threat and conservation

The lowland forests of this EBA were cleared by early settlers for timber, for spice and later coconut plantations, and for firewood to fuel the cinnamon distilleries. Today pockets of near-natural forest remain only at higher altitudes in the more inaccessible central areas but these often contain exotic species. Not surprisingly the islands have suffered many extinctions including the loss of two bird taxa, Psittacula wardi and Zosterops mayottensis semiflava, and at least 41% of their island populations of birds (Diamond 1984). Habitat alteration and predation by introduced cats and rats (especially black rat Rattus rattus) are the likely causes of most such extinctions, and these factors continue to be major threats. Fr
