In countries affected by the illegal wildlife trade, corruption is a key enabler and facilitator. Failure to address this corruption, and the institutional and governance gaps that allow it to take place, make tackling the illegal wildlife trade a significant challenge. This report provides a structured analysis of how corruption facilitates wildlife crime based on research in four source and transit countries in East and Southern Africa. It offers a series of specific recommendations targeted at national governments, donors, and intergovernmental organisations to address the issues of corruption and the illegal wildlife trade.
