Their cumulative impacts on native biotas alter the functioning of island ecosystems and threaten biodiversity. A report is given here of the first attempt to eradicate both taxa from a protected nature reserve in south-eastern France (Bagaud Island). In order to minimise unwanted hazardous outcomes and produce scientific knowledge, the operations were embedded in a four-step strategy including initial site assessment, planning, restoration and monitoring. RESULTSTrapping, which resulted in the removal of 1923 rats in 21045 trap-nights, made it possible to eliminate a substantial proportion of the resident rat population and to reduce the amount of rodenticide delivered in the second stage of the operation. Forty tons of Carpobrotus spp. were manually uprooted from a total area of 18000 m(2); yet careful monitoring over a decade is still required to prevent germinations from the seed bank. CONCLUSIONTwo years after the beginning of the interventions, both eradication operations are still ongoing. Biosecurity measures have been implemented to reduce reinvasion risks of both taxa. With the long-term monitoring of various native plants and animals, Bagaud Island will become a reference study site for scientific purposes. specialized biological invasions biosecurity ecosystem engineers pest management restoration species interactions MEDITERRANEE FRANCE 082 080 71 2 189-198 2015 1526-498X https://www.documentation.ird.fr/hor/fdi:010063657 10.1002/ps.3786 1526-498X [F B010063657] https://www.documentation.ird.fr/hor/fdi:010063657 https://www.documentation.ird.fr/intranet/publi/2015/02/010063657.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-03-03 2017-08-23 fdi:010063657 fre
