%X Sur le territoire du parc naturel r¨¦gional de Bri¨¨re, les invasions biologiques ne sont pas un ph¨¦nom¨¨ne nouveau et les cons¨¦quences s¡¯av¨¨rent d¡¯ores et d¨¦j¨¤ importantes ¨¦cologiquement, humainement et ¨¦conomiquement. Des r¨¦flexions et exp¨¦rimentations r¨¦unissant gestionnaires et scientifiques sont donc conduites localement afin qu¡¯¨¦mergent des m¨¦thodes de gestion adapt¨¦es ¨¤ la complexit¨¦ des probl¨¨mes pos¨¦s par les esp¨¨ces invasives. The Marshes of Brivet and Bri¨¨re, located at the north of the estuary of the River Loire, cover20.500 haregistered in the network of the sites Natura 2000 and mainly localised in the perimeter of the regional natural reserve of Bri¨¨re (49 000ha). Among the pressures which are exerted there on the conservation of the biodiversity and the uses, biological invasions are not a new phenomenon but in 2 decades, it increased and now is currently regarded as a major problem. For the manager, the success of control and even more the eradication of an immigrant species depends on implementation of human, financial, scientific, technical means largely exceeding the territorial limits¡­ and seldom joined together. However, the specific mono approach is confronted with the multiplication of invasive, animal and vegetable species, which increases the costs whereas the manager is in a context of limited means. The field manager must take into account huge ecosystemic changes, where inter specific exotic-native but also exotic-exotic relations appear; he solicits the scientists then. In collaboration, scientists and managers analyse the situation and test to pass from the complex management of invasive to the management of the complex of the invasive ones.
