"If the [first] 2016 World Wildlife Crime Report represented UNODC’s first global assessment of the state of wildlife crime, the 2020 edition of this report represents a first assessment of trends. In several instances, these trends have been dramatic. The poaching of both elephants and rhinoceroses has consistently declined since 2011, as have the prices paid for tusks and horns. But the amount of pangolin scales seized has increased 10-fold in just five years, and new markets, such as the trafficking of European glass eels, have emerged in the wake of strengthened controls. For the first time, a consistent pattern of large shipments of unrelated wildlife products – elephant ivory and pangolin scales – has emerged. In addition, organized criminal groups in broker countries, neither the source nor the destination of the wildlife, have consolidated control of multiple markets."
