It is clear that although the EU Wildlife Trade regulations can play a pivotal role in preventing further introductions in the region, e.g. reducing the movement of alien species which might become invasive, as well as those already introduced – they are not flexible enough to be adapted to the contingencies typical of alien species introductions. Therefore cannot work as a real and effective prevention tool, confirming the need for a specific EU legislation on invasive alien species.
