The two tree species (Dalbergia cochinchinensis and Dalbergia oliveri) are both are listed on Appendix II of CITES (the UN Convention on International Trade in Endangered Species) which recognizes that they are threatened and that their use needs to be strictly regulated. The CITES implementing authorities in Viet Nam undertook a study into the local health of the two species. It found that populations of both species are ‘small and fragmented’ and therefore decided to prohibit all harvesting and export of these rosewoods from the wild for the next five years. Listing under Appendix II of CITES means that any international trade in the species has to pose no risk to its survival. The study, which was carried out under the CITES Tree Species Programme recognized that further trade may pose a risk to the two species.
