Description: The Tromelin Island project conducted post-eradication of rats in 2005, focused on assessing ecosystem dynamics. Its primary objectives encompassed evaluating changes in seabirds, vegetation, and the impact of introduced mice on biodiversity. It investigated evolutionary patterns in these components and analysed the repercussions of the mice, contemplating eradication strategies. Through meticulous monitoring of biological indicators, the project sought comprehensive insights into inter-component interactions for refined island management strategies. Addressing the substantial threat of biological invasions, particularly introduced mammals, the project highlighted the vulnerability of island species to non-native predators due to a lack of evolutionary adaptations. Its comprehensive approach included investigating marine seabirds, vegetation, and grey mice, effectively managing and studying their interactions. Dissemination efforts, including presentations and the DyCIT project, enhanced regional understanding and capacity. Quantitative data generated by the project now supports effective island management, refining protocols for future initiatives and contributing significantly to the understanding and enhancement of island ecosystems.
