Île Ronde & Île aux Serpents

A Haven for Endemic Wildlife

Located off the northeastern coast of Mauritius, Île Ronde and Île aux Serpents are two of the country’s most important protected nature reserves. Managed by the Mauritian Wildlife Foundation, these islands serve as sanctuaries for endemic reptiles, rare bird species, and indigenous flora, playing a crucial role in the island’s biodiversity conservation efforts.
 
 

Île Ronde: A Conservation Success Story

Île Ronde, also known as Round Island, is a volcanic island covering approximately 1.69 km². It is home to critically endangered species such as the Round Island boa (Casarea dussumieri) and the Günther’s gecko (Phelsuma guentheri). The island’s dry coastal forest hosts rare plant species like the Round Island bottle palm (Hyophorbe lagenicaulis). Intensive restoration programs have helped in the repopulation of native plants and reptiles, making it one of Mauritius’ most successful ecological restoration projects.

Île aux Serpents: A Fragile Ecosystem

Île aux Serpents, meaning “Snake Island”, is a small, rocky islet with steep cliffs and sparse vegetation. Contrary to its name, the island is not home to snakes but supports seabird colonies, including the red-tailed tropicbird (Phaethon rubricauda). It was historically a habitat for endemic reptiles such as Telfair’s skink (Leiolopisma telfairii), which have since been translocated to other protected islands to ensure their survival.

Restricted Access for Conservation

Both Île Ronde and Île aux Serpents are strict nature reserves, meaning that public access is highly restricted. Only scientists and conservationists are permitted to visit under special authorization to ensure minimal human disturbance. This policy has been crucial in preventing invasive species introduction and preserving the islands’ fragile ecosystems.

Île Ronde and Île aux Serpents stand as critical sanctuaries for endangered species and native flora in Mauritius. Through ongoing conservation initiatives, these islands continue to safeguard the country’s rich biodiversity for future generations. Although public visits are not allowed, their ecological significance remains a testament to Mauritius’ dedication to wildlife preservation.
