Cos'è una specie esotica invasiva? Una specie vegetale o animale introdotta dall'uomo in un luogo diverso da quello di origine viene definita neobiota. Quando questi neobiota modificano il loro comportamento riproduttivo nel nuovo luogo, e danneggiano le specie locali vengono definite specie esotiche invasive. In Svizzera ne conosciamo circa un centinaio tra cui la coccinella asiatica e la palma di Fortune.
