Rodrigues is a 108 km2 autonomous outer island of the Republic of Mauritius in the Indian Ocean, about 560 km east of Mauritius. It is part of the Mascarene Islands, which include Mauritius and Réunion. Rodrigues is of volcanic origin and is surrounded by coral reef, and some tiny uninhabited islands lie just off its coast.
Rodrigues was characterised by endemic plant and animal species in abundance, but since the seventeenth century much of its biodiversity has been eradicated. The island was home to a now extinct endemic species of flightless bird, the Rodrigues solitaire, An endemic species of bat, the Rodrigues flying fox, is currently listed as endangered on the IUCN Red List. There are two remaining endemic bird species: the Rodrigues fody and the Rodrigues warbler, both are listed as near threatened.
To restore some forest areas, Grande Montagne, Anse Quitor and two islets, Île aux Sables and Île aux Cocos have been declared nature reserves, Endangered plants on the reserves include Zanthoxylum paniculatum, Polyscias rodriguesiana, Badula balfouriana, and Gouania leguatii.
