The use of rats to combat wildlife trafficking is gaining traction, with these highly intelligent rodents proving their worth in detecting illegal wildlife products such as pangolin scales, rhino horn, ivory, and African blackwood. Trained by researchers at Apopo, these rats are ideal for sniffing out concealed contraband in airports, seaports, and border crossings. Their small size, agility, and exceptional sense of smell make them effective allies in the fight against wildlife crime.
Despite being exposed to non-target odors and undergoing retention training, the rats exhibited excellent memory retention of wildlife scents even after months of non-exposure. The high-value products trafficked, like pangolin scales and rhino horn, fuel Africa’s illegal wildlife trade, posing a threat to biodiversity and wildlife conservation.
Future plans involve training the rats to operate in ports where trafficking occurs, equipped with custom vests to signal their handlers when contraband is detected. While the study showcases the rats’ potential, further developments are needed to deploy them effectively in real-world trafficking scenarios. This innovative approach holds promise in disrupting criminal networks exploiting both humans and nature.
