Invasive Pflanzen als Gefahr für die biologische Vielfalt

Abstract

Biological invasions are recognised as one of the biggest threats for biological diversity world wide. Also in Europe the awareness of this threat is recently increasing. Invasive plants in particular call for the reaction of both the environmental sector (nature conservation acts, CBD) and the agricultural (i.e. plant health, IPPC) sector. Most important is the prevention of new invasions triggered by human activities. This is the aim of legal measures, public awareness campaigns and the formulation and application of voluntary codes of conduct, e.g. in the gardening industry. The key instrument to decide which species should be targeted by policies against invasive species is the phytosanitary risk assessment (PRA) that is constantly being developed further, e.g. by the European Plant Protection Organisation (EPPO).
