Invasive alien species

Invasive Alien Species are animals and plants that are introduced accidentally or deliberately into a natural environment where they are not normally found, with serious negative consequences for their new environment. They represent a major threat to native plants and animals in Europe, causing damage worth billions of euros to the European economy every year. As invasive alien species do not respect borders, action at the European level will be more effective than action at the Member State level.
