DyCIT

The project main objective is to Increase the understanding of the interactions, both positive and negative, between the island’s marine birds, vegetation and mouse population to inform the management of the island and be used for other similar islands.

Abstract of the project:

DyCIT assess the dynamics of the small tropical island of Tromelin following the eradication of rats.
This is an essential aspect of the conservation of biodiversity and ecosystem services as the effects of an action must be assessed and quantified, including its temporal dimension, to inform effective management, reorient current actions and improve monitoring protocols. The learning from the project will be relevant for other similar island ecosystems, especially in the tropics.
The project focuses on the island’s seabirds and vegetation to assess how they have evolved since the rat eradication, and following the introduced mouse population to understand its impact on the island’s biodiversity and assess possibilities for eradication. The monitoring of these biological indicators produces information to future management actions for the island.
