There are various definitions of “wildlife crime”. For example, United Nations Office on Drugs and Crime (UNODC) defines it as "harvesting and trade contrary to national [and international] laws”. Wildlife crimes can be categorized differently, for instance, based on the motivations of the crime, the species targeted, and the methods used. National regulations may use a combination of these categorizations when describing these offences. This overview page provides a non-exhaustive list of wildlife crimes and some of the wildlife crime categorizations in use, which follow the scope of the SWiPE project. Due to this, there are some overlaps between the phenomena described by these categories.
