African Giant Pouched Rats have detected landmines for several years, and now they might be put to work stopping wildlife crimes. The U.S. Fish and Wildlife Service is allocating $100,000 to a trial project run by Endangered Wildlife Trust (EWT) in partnership with APOPO to see if giant rats can sniff out illegal shipments. The trial will determine if the rats can detect hardwood timber and pangolin scales and skin.
The US government is funding 12 creative methods of stopping wildlife trafficking and poaching in 11 different countries, and the giant rats program is one of them. APOPO, which was founded almost two decades ago, has already demonstrated the rats’ sharp sense of smell is useful for detecting landmines and tuberculosis, and the new trial project will determine whether they can pick out the smells of illegally trafficked products. The first step of the program is to assess if the rats can distinguish between control substances and target substances in a laboratory.
According to EWT project head Kirsty Brebner and program manager Adam Pires, the giant rats are “relatively cheap to source, feed, train, breed, and maintain, and their small size makes them cheap and easy to transport.” A typical rat lives between one and two years, but giant rats can live for as much as eight years.
Many illegal products are moved in shipping containers, and dogs have provided some help in sniffing out shipments in the past. But with superior agility and ability to reach container vents, giant rats might be able to detect illegal products more effectively than a dog can.
EWT says if the program is successful, the giant rats may be trained to also detect other illegally trafficked products like rhino horns and elephant ivory.
