The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)
Monitoring and Reporting 
The monitoring of trade is an essential tool for achieving the aims of the Convention. Scientific Authorities monitor export permits granted for Appendix II species and the actual export thereof. They advise their Management Authorities on when to limit the issue of export permits whenever they determine that exports should be limited in order to maintain a species throughout its range at a level consistent with its role in the ecosystems in which it occurs and well above the level at which it might become eligible for inclusion in Appendix I.
A second important monitoring system is based on the trade records kept by all Parties and reported to the Secretariat on an annual basis. In their annual reports, Parties are required to submit data on all trade in specimens of species covered by CITES. Trade data from all Parties together provides statistical information on the total volume of world trade in CITES species, which is available here.
These annual reports further reflect the performance of Parties regarding CITES implementation when all reported exports and re-exports are compared with all reported imports. In addition to the compilation of annual reports, the European Commission has been publishing an analysis of the EU annual reports, the so-called "Yearbook".
Thirdly, Parties report to the Secretariat every two years for the so-called Biennial Report on the legislative, regulatory and administrative measures taken to ensure enforcement of CITES.
