Resumen de Les xénophytes de Corse: un danger pour la flore indigène
The corsican flora contain 17.1% of introduced plants (xenophytes). We caracterize here their origin, frequency, dynamism, mode and date of introduction. Main types of xenophytes are given, in particular by their degree of naturalization and penetration in the natural vegetation. We show that these plants are a danger for the indigenous flo-ra. Propositions of actions against these xenophytes and to protect the indigenous flo-ra are presented.
