GENEVA — The fate of mako sharks, African elephants and their ivory, and precious wood used to make musical instruments are on the agenda of member states attending negotiations of the U.N. wildlife watchdog. The Convention on International Trade in Endangered Species (CITES) regulates the buying and selling of species at risk of extinction around the world, either by imposing outright bans or by requiring permits so that rare animals and plants are not over-harvested. The 183 states… meet in Geneva from Aug 17-28 to consider 56 proposals to expand a legally binding treaty which already covers 36,000 species. …The EU and Canada are proposing that musical instruments made of rosewood be exempted from existing CITES controls on precious woods requiring trade permits.
