The global illegal wildlife trade has been anecdotally linked to other serious crimes, such as fraud, corruption, and money laundering, as well as the cross-border trafficking of drugs, arms, counterfeit goods, and persons. As research on this topic is scarce and sporadic, we conducted a scoping literature review to gather information across multiple disciplines and evidence types on crime convergences in the illegal wildlife trade. We reviewed 150 papers published between 2000 and 2020. We found that the illegal trade in many of the most frequently trafficked species have reportedly converged with numerous other serious and organised crimes, most commonly drug trafficking. Convergences can occur in a variety of ways, although the diversification of organised crime groups, parallel trafficking of contraband, and use of enabling crimes (such as corruption and violence) were the most frequently described. Possible explanations for our results and future research directions are discussed.
