Relief and climate

Seychelles, one of the worlds smallest countries, is composed of two main island groups: the Mah group of more than 40 central, mountainous granitic islands and a second group of more than 70 outer, flat, coralline islands. The islands of the Mah group are rocky and typically have a narrow coastal strip and a central range of hills. The overall aspect of those islands, with their lush tropical vegetation, is that of high hanging gardens overlooking silver-white beaches and clear lagoons. The highest point in Seychelles, Morne Seychellois (2,969 feet [905 metres]), situated on Mah, is located within this mountainous island group. The coralline islands, rising only a few feet above sea level, are flat with elevated coral reefs at different stages of formation. These islands are largely waterless, and very few have a resident population.

Explore La Digue island and discover the efforts to preserve the culture, traditions, and flora and fauna of the island

Overview of La Digue island, Seychelles.

The climate is tropical oceanic, with little temperature variation during the year. Daily temperatures rise to the mid-80s F (low 30s C) in the afternoon and fall to the low 70s F (low 20s C) at night. Precipitation levels vary greatly from island to island; on Mah, annual precipitation ranges from 90 inches (2,300 mm) at sea level to 140 inches (3,560 mm) on the mountain slopes. Humidity is persistently high but is ameliorated somewhat in locations windward of the prevailing southeast trade winds.

Of the roughly 200 plant species found in Seychelles, some 80 are unique to the islands, including screw pines (see pandanus), several varieties of jellyfish trees, latanier palms, the bois rouge, the bois de fer, Wrights gardenia, and the most famous, the coco de mer. The coco de merwhich is found on only two islandsproduces a fruit that is one of the largest and heaviest known and is valued by a number of Asian cultures for believed aphrodisiac, medicinal, mystic, and other properties. The Seychellois government closely monitors the quantity and status of the trees, and, although commerce is regulated to prevent overharvesting, poaching is a concern.

Explore Bird Island in Seychelles, a breeding place for countless species of birds

Overview of Bird Island, Seychelles.

Wildlife includes a remarkably diverse array of marine life, including more than 900 identified species of fish; green sea turtles and giant tortoises also inhabit the islands. Endemic species include birds such as Seychelles bulbuls and cave-dwelling Seychelles swiftlets; several species of local tree frogs, snails, and wormlike caecilians; Seychelles wolf snakes and house snakes; tiger chameleons; and others. Endemic mammals are few; both fruit bats (Pteropus seychellensis) and Seychelles sheath-tailed bats (Coleura seychellensis) are endemic to the islands. Indian mynahs, barn owls, and tenrecs (small shrewlike or hedgehoglike mammals introduced from Madagascar) are also found.

Considerable efforts have been made to preserve the islands marked biodiversity. Seychelles government has established several nature preserves and marine parks, including the Aldabra Islands and Valle de Mai National Park, both UNESCO World Heritage sites. The Aldabra Islands, a large atoll, are the site of a preserve inhabited by tens of thousands of giant tortoises, the worlds oldest living creatures, which government conservation efforts have helped rescue from the brink of extinction. Valle de Mai National Park is the only place where all six of the palm species endemic to Seychelles, including the coco de mer, may be found together. Cousin Island is home to a sanctuary for land birds, many endemic to the islands, including the Seychelles sunbird (a type of hummingbird) and the Seychelles brush warbler. The nearby Cousine Island is part private resort and part nature preserve, noted for its sea turtles, giant tortoises, and assorted land birds. Bird Island is the breeding ground for millions of terns, turtle doves, shearwaters, frigate birds, and other seabirds that flock there each year.
