Mascarene Islands
The Mascarene Islands (or Mascarenhas Archipelago) is a group of islands in the Indian Ocean east of Madagascar consisting of Mauritius, Réunion and Rodrigues. The collective title is derived from the Portuguese navigator Pedro Mascarenhas, who first visited them in the early sixteenth century. The islands share a common geologic origin in the volcanism of the Réunion hotspot beneath the Mascarene Plateau and form a distinct ecoregion with a unique flora and fauna.
