Under CITES, Appendix III lists species protected by how many countries?

CITES, or the Convention on International Trade in Endangered Species of Wild Fauna and Flora, has three appendices that categorize different species based on the level of protection required. Appendix III specifically includes species that are protected in at least one country, meaning that these countries have requested the inclusion of these species in order to curb illegal trade. The listings in Appendix III can vary significantly depending on the countries' conservation efforts and objectives.

This understanding is crucial in recognizing that the protection of a species under Appendix III may arise from the legal frameworks or conservation priorities of individual nations. Consequently, the correct answer highlights the minimal requirement of protection, which is the presence of at least one country advocating for the conservation of a species listed under this appendix.
