CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement between governments. It is refers only to international trade so not to damage or theft. The only UK species to which CITES applies are Snowdrop Galanthus nivalis, if this is native, and all of the wild orchids. Wild snowdrops are fully protected under law, which means that they must never be picked or lifted from their wild or existing habitat.
