Wildlife trafficking is the illegal cross-border trade in live wildlife, wildlife products or their derivatives, both of fauna and flora. It is one of the most lucrative types of transnational crime along with the illegal trade in drugs, counterfeit goods and human trafficking. This report was prepared in advance of a three-day workshop organised in Dar Es Salaam, Tanzania by TRAFFIC, UNDP and UNODC, which brought together key port stakeholder groups to discuss ways to counter wildlife trafficking through Tanzania's sea ports.
