First paragraph: Great ape conservation experts from the Great Apes Survival Partnership (GRASP) and the International Union for Conservation of Nature (IUCN) recently produced a report on the status of great apes and threats to their survival for CITES - the Convention on International Trade in Endangered Species of Wild Fauna and Flora (GRASP & IUCN 2018). During preparation of this report, we were asked to review usage of the word "poaching" and clarify its different meanings.
