摘要: Invasive alien species (IAS) have been identified as one the most important direct drivers of biodiversity loss and ecosystem service changes. Many international policy instruments, guidelines and technical tools have been developed to address the threat of IAS.The Convention on Biological Diversity (CBD) at art. 8 (h) calls for parties “as far as possible and as appropriate,(to) prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species”. In 2002 the CBD Conference of the Parties adopted the Guiding Principles on Invasive Alien Species (Decision VI/23) as a basic policy response. The first CBD guiding principle state that prevention is generally far more cost-effective and environmentally desirable than measure taken after IAS introductions.
