Cousine Island is a small granitic island in the Inner Islands of the Seychelles, close to Praslin, that is managed primarily as a nature reserve. The island is internationally noted for conservation programs aimed at restoring native vegetation and recovering threatened bird species.

The island’s highlights are dense native scrub and forest patches, seabird colonies and beaches used by nesting marine turtles, together with active habitat restoration projects. Guided visits and ecotourism are restricted to minimise impact and support conservation work.

Conservation management over recent decades has focused on invasive species control, habitat restoration and species reintroductions to rebuild native fauna and flora. The island carries out ongoing monitoring of breeding birds and turtle nesting.

Cousine lies close to Praslin in the central Seychelles archipelago and is reached by short boat trip from neighbouring inhabited islands.

  • Conservation focus: Managed as a protected conservation reserve focused on seabirds, land birds and marine turtle protection, with limited visitor numbers to reduce disturbance.
  • Access: Only a small resident conservation staff live on the island; most visits are by arrangement with the reserve managers.
