The Ua Pou islets Pacific rat eradication operation was undertaken in August-September 2023. It attempted a global first of aerially broadcasting rodent bait by drone from a small ship in open sea across the islets of Motu Tākaè, Motu Oa, and Motu Mokohe, at Ua Pou in the Marquesas Islands. The aerial bait application resulted in only two of the three islands having bait successfully applied across their entirety, nonetheless, monitoring 12 months later has confirmed Motu Oa and Motu Tākaè are rat free as is the partially isolated section of Motu Mokohe that was also baited. The eradication success is supported by the establishment of biosecurity knowledge and practices throughout the Ua Pou communities. The results of the seabird and other environmental monitoring will help sustain a commitment over time, as well as benefiting the wider conservation community. The operation demonstrated that drones could be operated off a boat for rodent eradication purposes but was constrained by the consistently strong winds and swell conditions. A larger vessel with a deeper draught is recommended for similar operations in the future and would likely increase the number of flyable days and improve the ease with which take-offs and landings are undertaken by the drone pilots.

Ce rapport est l'un des principaux résultats de l'atelier régional Sea'ties Pacifique qui s'est tenu du 10 au 12 juillet 2023 à Nadi (Fidji). L'atelier a été organisé par la Plateforme Océan & Climat, le Programme régional océanien de l'environnement (PROE), et le Pacific Climate Change Pacifique (PCCC), avec le soutien financier du Fonds de coopération économique, sociale et culturelle pour le Pacifique (« Fonds Pacifique », Ministère de l’Europe et des Affaires Etrangères), du PCCC, et du PROE par le biais du programme d’assistance technique de l’Initiative Kiwa. Le rapport fournit une vue d'ensemble des défis actuels en matière d'adaptation dans la région du Pacifique, ainsi que des initiatives inspirantes pour les relever. Les conclusions de ce rapport s'appuient sur les points de vue exprimés lors d’entretiens et sur les discussions de l'atelier lui-même. Il souligne et démontre à quel point, dans une région où de nombreuses îles sont de faible altitude, où la grande majorité de la population vit au bord de l'océan et où la côte s'urbanise rapidement, l'élévation du niveau de la mer reste une question existentielle et qu'il est primordial d'accélérer les mesures d'atténuation et d'adaptation.

The tropical Marquesas islands are characterised by their isolation and high levels of endemicity among native fauna and flora. This includes forty-two percent of the 320 native vascular plants and a diverse terrestrial snail community, with at least 78 species represented. Of the 12 native land birds 11 occur only within the archipelago, several restricted to a single island. Nineteen species of seabird breed there including the most eastern population of the Endangered Phoenix Petrel. Monitoring of seabirds and other species before, during and after the project will inform the impact of removing rats from these islets including how endangered species respond and community interest.
