The Democratic Republic of Congo’s proposal to transfer the Golden-bellied mangabeys from Appendix I to Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) has been unanimously adopted by the Parties to CITES at their 20th Conference (COP20) sitting at Samarkand, Uzbekistan. The species, found only in DRC, is one of Africa’s least-known and most threatened monkeys. We therefore congratulate the DRC and all the Parties to CITES upon this very important decision that ensures the species’ survival.
