French Polynesia is a French overseas collectivity in the South Pacific, comprising 118 islands and atolls grouped into five archipelagos: Society Islands, Tuamotu, Gambier, Marquesas, and Austral Islands. Tahiti, in the Society Islands, is the largest and most populated. Its ecosystems include tropical forests, lagoons, coral reefs, and high volcanic peaks, supporting rich biodiversity and cultural heritage. In recent years, French Polynesia has advanced invasive species management through the development of a National Invasive Species Strategy and Action Plan (NISSAP, 2025–2030), aligned with its updated National Biodiversity Strategy and Action Plan (NBSAP 2026–2030) under the Kunming–Montreal Global Biodiversity Framework.
Overview
Biodiversity Status
High levels of endemism, including unique birds (e.g., Tahiti monarch, Marquesan kingfisher). Coral reefs and lagoons are globally significant, supporting fisheries and tourism. Tropical forests and volcanic peaks host rare plants and invertebrates. Protected areas exist but remain limited in coverage.
Invasive Species Threats
Invasive species includes Miconia calvescens (“green cancer”), African tulip tree, Merremia peltata, rats, feral cats, pigs, goats, little fire ant and invasive mosquitoes which are causing forest degradation, crop loss, coral reef damage and threats to endemic birds.
National Strategies & Plans
French Polynesia has a NISSAP 2025–2030, endorsed by government. Integrated with the updated NBSAP 2026–2030. Focus areas include biosecurity, eradication of invasive plants, predator control, ecosystem restoration, and community awareness.
