Eradications as scientific experiments: progress in simultaneous eradications of two major invasive taxa from a Mediterranean island.

摘要: Black rats, Rattus rattus, and mat-forming iceplants, Carpobrotus aff. acinaciformis edulis, are pervasive pests on Mediterranean islands. Their cumulative impacts native biotas alter the functioning of island ecosystems threaten biodiversity. A report is given here first attempt to eradicate both taxa from a protected nature reserve in south-eastern France (Bagaud Island). In order minimise unwanted hazardous outcomes produce scientific knowledge, operations were embedded four-step strategy including initial site assessment, planning, restoration monitoring.[br/] Trapping, which resulted removal 1923 rats 21 045 trap-nights, made it possible eliminate substantial proportion resident rat population reduce amount rodenticide delivered second stage operation. Forty tons spp. manually uprooted total area 18 000 m(2) ; yet careful monitoring over decade still required prevent germinations seed bank.[br/] Two years after beginning interventions, eradication ongoing. Biosecurity measures have been implemented reinvasion risks taxa. With long-term various plants animals, Bagaud Island will become reference study for purposes.
