Île aux Aigrettes

Île aux Aigrettes is a 26-hectare coral island located off the southeast coast of Mauritius in Mahébourg Bay. Unlike the volcanic main island, it is composed of coralline limestone, providing a distinct ecosystem. This reserve is home to the last remnants of dry coastal forest, once abundant around Mauritius. Due to deforestation and invasive species, the island underwent significant habitat restoration, making it a leading conservation site.

Conservation Efforts

Declared a nature reserve in 1965, Île aux Aigrettes has undergone extensive restoration led by the Mauritian Wildlife Foundation (MWF). The main objectives have been the removal of invasive species, reintroducing endemic flora and fauna, and restoring the coastal forest ecosystem. This conservation work has transformed the islet into an open-air laboratory, where scientists monitor endangered species and ensure their survival.

Flora and Fauna

Île aux Aigrettes is home to some of Mauritius’s rarest species, including the pink pigeon, once nearly extinct. The island also shelters the Mauritius fody, the Mauritius olive white-eye, and Telfair’s skink. Visitors can also spot Aldabra giant tortoises, reintroduced to mimic the role of the extinct giant tortoise in seed dispersal. The ebony trees, once decimated for trade, are now being replanted to restore the island’s original ecosystem.
