Definition: A taxon is Vulnerable when the best available evidence indicates that it meets any of the
criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.
Definition: Appendix I lists species that are the most endangered among CITES-listed animals and plants. They are threatened with extinction and CITES prohibits international trade in specimens of these species except when the purpose of the import is not commercial, for instance for scientific research. In these exceptional cases, trade may take place provided it is authorized by the granting of both an import permit and an export permit (or re-export certificate). Article VII of the Convention provides for a number of exemptions to this general prohibition.
