Main articles: Geography of Mauritius and Outer islands of Mauritius

The total land area of the country is 2040 km2, which is the 180st largest nation in the world by size. The Republic of Mauritius also incorporates the island of Rodrigues, situated some 560 kilometers to the east and is 104 km2 in area, the Agaléga situated some 1,000 km to the north of Mauritius and Saint Brandon situated some 430 km to the north-east of Mauritius, both with total land area of 71.2 km2. Mauritius claim sovereignty over Tromelin islands, small islands that lie 430 km to the north-east of Mauritius. The nation's exclusive economic zone (EEZ) cover about 1.2 million square kilometers of the Indian Ocean. Four fishing banks fall within EEZ limits, the Soudan Banks (including East Soudan Bank), Nazareth Bank, Saya de Malha Bank, Hawkins Bank. In 2011 the United Nations endorsed the joint submission of Mauritius and Seychelles to extend their continental shelf of 396,000 km2 in the Mascarene region which gives the two countries sovereign right to jointly manage and exploit the seabed and subsoil of the joint area.

The island of Mauritius is relatively young geologically, having been created by volcanic activity some 8 million years ago. Together with Saint Brandon, Réunion and Rodrigues, the island is part of the Mascarene Islands. These islands have emerged from the abysses as a result of gigantic underwater volcanic eruptions that happened thousands of kilometres to the east of the continental block made up by Africa and Madagascar. They are no longer volcanically active and the hotspot now rests under Réunion island. There has been no active volcano on Mauritius island for more than 100,000 years. Mauritius is encircled by a broken ring of mountain ranges, varying in height from 300 meters to 800 meters above sea level. The land rises from coastal plains to a central plateau where it reaches a height of 670 meters, the highest peak is in the southwest, Piton de la Petite Rivière Noire at 828 metres (2,717 ft). Streams and rivers speckle the island, a lot of them are formed in the cracks created by lava flows.

The island of Mauritius is situated some 2,000 kilometres (1242 miles) off the south east coast of the African continent, between Latitudes 19°58.8' and 20°31.7' South and Longitudes 57°18.0' and 57°46.5' East, it is 65 km long and 45 km wide, its land area is 1,864.8 km2. Mauritius is surrounded by more than 150 kilometres (93 miles) of white sandy beaches and the lagoons are protected from the open sea by the world's third largest coral reef, which surrounds the island. Just off the Mauritian coast lie some 49 uninhabited islands and islets (see Islets of Mauritius), some of them are used as natural reserves for the protection of endangered species.

Mauritius sought to regain sovereignty over the Chagos Archipelago situated 1287 km to the north east (see Chagos Archipelago sovereignty dispute). The Government of the Republic of Mauritius does not recognise the British Indian Ocean Territory, which the United Kingdom created by excising the Chagos Archipelago from the territory of Mauritius prior to its independence. Mauritius claims that the Chagos Archipelago, including Diego Garcia, forms an integral part of the territory of Mauritius under both Mauritian law and international law. Starting in the 1960s, the islands 2,000 residents were gradually removed as a process of enabling the United States to establish a military base on the island. The Chagossians has since engaged in activism to return to the archipelago, claiming that the forced expulsion and dispossession was illegal.

Environment The tropical beach at Trou-aux-Biches. Main article: Climate of Mauritius

The environment in Mauritius is typically tropical in the coastal regions with forests in the mountainous areas. Seasonal cyclones are destructive to the flora and fauna, although they recover quickly. Mauritius ranked second in an air quality index released by the World Health Organization in 2011.

Situated near the tropic of Capricorn, Mauritius has a tropical climate. There are 2 seasons: a warm humid summer from November to April, with a mean temperature of 24.7° and a relatively cool dry winter from June to September with a mean temperature of 20.4°. The temperature difference between the seasons is only 4.3°. The warmest months are January and February with average day maximum temperature reaching 29.2° and the coolest months are July and August when average night minimum temperatures drops down to 16.4°. Annual rainfall ranges from 900 mm on the coast to 1,500 mm on the central plateau. Although there is no marked rainy season, most of the rainfall occurs in summer months. Sea temperature in the lagoon varies from 22° to 27°. The central plateau is much cooler than the surrounding coastal areas and can experience as much as double the rainfall. The prevailing trade winds keep the East side of the island cooler and also tends to bring more rain. There can also be a marked difference in temperature and rainfall from one side of the island to the other. Occasional tropical cyclones generally occurs between January to March and tend to disrupt the weather for only about three days bringing a lot of rain.

The country is home to some of the world's rarest plants and animals but human habitation and the introduction of non-native species have threatened its indigenous flora and fauna. Due to its volcanic origin, age, isolation and its unique terrain, Mauritius is home to a diversity of flora and fauna not usually found in such a small area. Before its discovery by the Portuguese in 1507, there were no terrestrial mammals on the island. This allowed the evolution of a number of flightless birds and large reptile species. The arrival of man saw the introduction of invasive alien species and the rapid destruction of habitat and the loss of much of the endemic flora and fauna. Less than 2% of the native forest that once stretched from the mountain tops of the central plateau to the shore now remains, concentrated in the Black River Gorges National Park in the south west, the Bamboo Mountain Range in the south east and the Moka-Port Louis Ranges in the north west. There are also some isolated mountains which are Corps de Garde, Le Morne Brabant and several offshore islands with remnants of coastal and mainland diversity. Over 100 species of plants and animals have become extinct and many more are threatened. Conservation activities began in the 1980s with the implementation of programmes for the reproduction of threatened bird and plant species as well as habitat restoration in the National Parks and Nature Reserves.

Mauritius was the only known habitat of the now-extinct Dodo bird.

When it was discovered, the island of Mauritius was the home of a previously unknown species of bird, the Dodo. Dodos were descendent of a type of pigeon which settled in Mauritius over 4 million years ago. With no predators to attack them, they lost their need and ability to fly. In 1505, the Portuguese became the first humans to set foot on Mauritius. The island quickly became a stopover for ships engaged in the spice trade. Weighing up to 50 pounds, the dodo was a welcome source of fresh meat for the sailors. Large numbers of dodos were killed for food. Later, when the Dutch used the island as a penal colony, new species were introduced to the island. Rats, pigs and monkeys ate dodo eggs in the ground nests. The combination of human exploitation and introduced species significantly reduced the dodo population. Within 100 years of the arrival of humans on Mauritius, the once abundant dodo became a rare bird. The last one was killed in 1681. The dodo is prominently featured as a supporter of the national Coat of arms of Mauritius.

Districts Main article: Districts of Mauritius

Mauritius is divided into nine districts which consist of different cities, towns and villages. The island of Rodrigues used to be the country's tenth district before it gained autonomous status in 2002.
