%X Mener une politique de gestion efficace contre les ph¨¦nom¨¨nes de prolif¨¦ration des esp¨¨ces exotiques envahissantes passe par des mesures de r¨¦glementation, mais aussi de pr¨¦vention, n¨¦cessitant la mise en place de r¨¦seaux organis¨¦s de surveillance et de d¨¦tection pr¨¦coce de nouvelles esp¨¨ces sur le territoire. Comment mieux organiser ces r¨¦seaux et coordonner l'action des diff¨¦rents acteurs, scientifiques, gestionnaires, associations et pouvoirs publics ? Quelques pistes nous sont sugg¨¦r¨¦es dans cet article. It is quite difficult to eradicate an invasive alien species when it has already begun to spread. Even containment is very complicated, expensive andmay be harmful for natural ecosystems. For these reasons, it is necessary to improve prevention in order to foresee future invasions. The creation of a national list prioritized by negative impacts and specifying restrictivemeasures (black list) would be a consistent progress for the enhancement of actual legislation and the nation could take a step forward on the way to prevention. In the same way, voluntary approaches and participative initiatives can be developed as it is already done for several years with different stakeholders. Finally, because of the unfeasibility tomaster the knowledge of incoming species, setting up surveillance networks is essential. These networks are useful for a better detection of newly established species, but they alsomust facilitate rapid responses to control incipient populations of undesirable invaders. With the purpose of driving these networks to optimization, early detection areas have to be targeted and specific toolsmust be developed. This new strategy also involves a better targeting and training of the stakeholders that willmake it become alive.
