terrestrial biodiversity on various biological compartments: avifauna by terrestrial and bioacoustic monitoring, vascular flora and vegetation, arthropods and reptiles. These inventories aim to establish an initial biological state of the islands of Gargalu and Garganellu, to identify species potentially impacted by an eradication of black rats. The conclusions of the rat extermination feasibility study presented in this note conducted to a partial control of the rat population on Gargalu and the eradication from Garganellu (1.4 ha).
