In a related area, the BV forum mentions CITES when speaking of snakeskin. Here is some information from the CITES website:
http://www.cites.org
CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement between governments. Its aim is to ensure that international trade in specimens of wild animals and plants does not threaten their survival.
Because the trade in wild animals and plants crosses borders between countries, the effort to regulate it requires international cooperation to safeguard certain species from over-exploitation. CITES was conceived in the spirit of such cooperation. Today, it accords varying degrees of protection to more than 30,000 species of animals and plants, whether they are traded as live specimens, fur coats or dried herbs.
CITES was drafted as a result of a resolution adopted in 1963 at a meeting of members of IUCN (The World Conservation Union). The text of the Convention was finally agreed at a meeting of representatives of 80 countries in Washington DC., United States of America, on 3 March 1973, and on 1 July 1975 CITES entered in force.
CITES is an international agreement to which States (countries) adhere voluntarily. States that have agreed to be bound by the Convention ('joined' CITES) are known as Parties. Although CITES is legally binding on the Parties in other words they have to implement the Convention it does not take the place of national laws. Rather it provides a framework to be respected by each Party, which has to adopt its own domestic legislation to ensure that CITES is implemented at the national level.
For many years CITES has been among the conservation agreements with the largest membership, with now 174 Parties.
The species covered by CITES are listed in three Appendices, according to the degree of protection they need.
Appendix I includes species threatened with extinction. Trade in specimens of these species is permitted only in exceptional circumstances.
Appendix II includes species not necessarily threatened with extinction, but in which trade must be controlled in order to avoid utilization incompatible with their survival. The Burmese python is in this appendix.
Appendix III contains species that are protected in at least one country, which has asked other CITES Parties for assistance in controlling the trade.
