[General description section]

I am an EDGE Fellows working on four endemic EDGE species, the sooglossid frogs. I am currently working as a Research Officer for the Seychelles National Parks Authority.


This project is part of the ‘A cutting-EDGE approach to saving Seychelles’ evolutionary distinct biodiversity’ project in collaboration with several local and international partners/institutions and co-financed by the Darwin Initiative. Most of the work previously conducted on the Sooglossidae has focused on taxonomic and phylogenetic studies with very few field studies investigating the distribution patterns, ecology and conservation requirements of this IUCN Red-listed frog family, endemic to the Seychelles granitic islands.


Through my EDGE Fellowship I aim to improve our knowledge on sooglossid frog distribution and abundance and develop a national monitoring programme. I will be doing this across Mahé, Praslin and Silhouette islands in the Seychelles Archipelago. In this project, I will conduct extensive field surveys on the islands, inside and outside of protected areas, and set up a long term monitoring programme within the Morne Seychellois National Park and other protected areas. We intend to collect more data on ecological variables of the 4 known sooglossid frogs.


Our lack of knowledge is clearly hampering conservation planning efforts and merely having sooglossid frogs present in protected areas may not be enough to ensure their long-term survival. Our aims are therefore:
•To enhance our knowledge on the four known sooglossid frogs’ ecology, focusing on their distribution patterns and habitat requirements.
•To explore the current and potential threats posed by introduced species, diseases, climate change, and land use within protected areas.
•To develop a comprehensive conservation action plan that will mobilise more funding and action on the ground across all protected areas.

Relevant species

Tadpoles develop on the parents back until they have metamorphosed into froglets capable of independent living.

The Seychelles palm frog was described as a new species in 2002 and is only found within a tiny range on Silhouette Island.

Thomasset‘s frog is the largest and rarest species in the Seychelles frog family.

This species is among the smallest frogs in the world, with adults measuring just 11 mm in length.
