Appendix I includes over 1,000 species threatened with extinction. Commercial trade in specimens of these species is prohibited. Appendix I captive-bred animals from CITES registered operations and artificially propagated plants bred/propagated for commercial purposes are treated as Appendix II specimens.
Appendix II lists over 39,000 species which are not necessarily threatened with extinction but may become so unless trade is controlled. Their trade is allowed but subject to licensing controls.
Appendix III species are species identified by any Party to CITES as requiring cooperation in controlling their trade. Their trade is subject to permits or certificates of origin.
