摘要: Many European politicians, managers, and scientists believe that non-indigenous species cannot be eradicated attempts to do so are hazardous because of frequent undesirable results. This notion seems based on the view successful eradications undertaken in many other parts world generalised. To allow reasoned consideration this argument, eradication vertebrate performed French territories (European overseas) their recorded consequences native fauna flora synthesised. Nineteen were recorded, with seven mammal as targets. Of these four failed for technical reasons one undetermined yet. These operations took place islands biogeographical areas (West-European, Mediterranean, West Indies Indian Ocean subantarctic) except a continental (West-European continent). Among 19 attempts, 13 conducted according global strategy provided data impact disappearance several species. impact, never detrimental, was determined 14 (one mammal, nine birds, marine turtle, crab, beetle, plant). Unexpected invader (29%). result highlights poverty natural historical information taxa flimsiness empty niche concept is often used argue delay or prevent any action again If can taken an example, not impossible; good risk assessment prevents long-term benefited from invader. Furthermore, constitutes powerful experimental tool ecology history studies if conceived both management research operation.
