ABSTRACT Invasive alien species (IAS) are alien species that threaten ecosystems, habitats, or other species. Article 8(h) of the Convention on Biological Diversity (CBD) requires the contracting parties to prevent the introduction of or control or eradicate those alien species that threaten ecosystems, habitats, or species. Members are also required to lodge National Reports with the Secretariat of the CBD, specifying how they are fulfilling their international obligations with respect to IAS. While the threats to biodiversity posed by IAS have been extensively documented,to date, no study has examined states perceptions of their IAS regimes. This Article collects and analyzes information available from the CBD National Reports to consider what members themselves have identified as their regulatory strengths and weaknesses. Against this backdrop, the Article evaluates the effectiveness of international environmental law in guiding domestic regimes, highlighting that where international law is imprecise or inconsistent, it can hinder the development of successful State practice.
