Wildlife crime is a multi-billion-dollar industry. After drug, arms, and human trafficking, the illegal trade in wildlife is among the most lucrative forms of crime, with an estimated value of over $20 billion per year according to Interpol. Gaining insight into trafficking routes and poaching hotspots is therefore crucial.
DNA is playing an increasingly important role in this effort. Thanks to years of research into genetic variation in lions, we now have a detailed genetic map showing how different populations are structured. In collaboration with international colleagues, a genetic panel has been developed that allows the origin of lions to be determined quickly and accurately. This panel can not only identify where a lion comes from, but in some cases even pinpoint the exact individual, comparable to a DNA fingerprint in humans.
Colleagues in Zimbabwe have now successfully applied this panel in a court case against poachers. Confiscated body parts, such as teeth and skin, were not only identified as originating from lions, but were also genetically matched to a specific individual that had previously been monitored by researchers. This provided decisive evidence, leading to the conviction of the poachers.
This is the first time that lion DNA has been used in this way in a criminal case. Leo Foundation is involved in this research, and we will share further updates in the future. This case represents an important milestone, demonstrating how fundamental genetic research can directly contribute to the protection of wildlife.
