The Glorieuses have anExclusive Economic Zone (EEZ) of 48,350 square kilometres (18,670 sq mi). There are anchorages offshore, and Grande Glorieuse has a 1,300-metre (4,300 ft) longairstrip.
The climate is tropical and the terrain is low and flat, varying in height from sea level to 12 metres (39 ft). Île de Lys in particular is a nesting ground formigratoryseabirds, andturtles lay eggs on the beaches. In the ocean, migratory species such ashumpback whales andwhale sharks may appear.[6]
While probably earlier known to Arab (perhaps especially Yemeni) navigators, the Glorieuses were named and settled in 1880 by aFrenchman, Hippolyte Caltaux, who established acoconut plantation on Grande Glorieuse. The archipelago became a French possession in 1892[7] when Captain Richard of thePrimauget made a formal claim. In 1895, the Glorioso Island became a part of thecolony of Mayotte and dependencies.
Historically flora on the islands mostly consisted ofbois de rose,portia,banyan and other large native trees, many of which were felled following the establishment of the French settlement and plantation.[8]
The Scattered Islands in the Indian Ocean are partially claimed by the Comoros, Madagascar, and Mauritius.[13] The Malagasy and Mauritian claims, however, are significantly later than their access to independence. However, the agreement reached in October 2024 on the restitution to Mauritius of the Chagos Islands by Great Britain, in the heart of the Indian Ocean, notably home to the American base of Diego Garcia, has relaunched the debate in Madagascar.[14]
