A paper titled “Real-time Tomographic 3D X-ray Imaging and Automated Algorithms to Detect Illicit Trade in Wildlife” Frontiers of Conservation Sciencewas the first to document the use of 3D X-ray CT scanning technology for wildlife conservation in the scientific literature.

This study is the result of a detection and protection agency. The Department of Agriculture, Fisheries and Forestry (DAFF), the Department for Climate Change, Energy, Environment and Water (DCCEEW), Lapiscan Systems and Australia’s Taronga Conservation Society have joined forces to prevent illegal wildlife trafficking through mail and traveler parcel routes. combating illegal smuggling.

Chris Locke, Deputy Director of the DAFF’s Biosecurity and Compliance Group, and Sam Hush, Acting Deputy Director for Environmental Compliance, DCCEEW, said the paper, published in the Frontiers Human-Wildlife Interactions journal of Conservation Science, We have provided reported results for wildlife classes mentioned (lizards, birds, fish, etc.) displayed within 3D X-ray CT security scan images.

“Illegal wildlife trafficking poses a significant biosecurity risk to Australia as it can introduce pests and diseases that can affect the environment as well as human and animal health.” said Dr. Locke.

“This paper demonstrates the endless potential of 3D X-ray algorithms to help deter exotic wildlife trafficking and help protect the Australian agricultural industry and unique natural environment from exotic pests and diseases.

“This innovative technology is an invaluable platform that complements existing biosecurity and wildlife detection tools at Australian borders, with potential for global applications in the future.”

Hush said wildlife trafficking is also detrimental to Australia’s biodiversity.

“Removing wildlife from the wild poses risks to species conservation, local populations, habitats and ecosystems, and preventing wildlife from being trafficked into Australia is critical to protecting animals from alien pests and diseases. It protects our unique natural environment,” Hash said.

“It’s also very cruel. Smuggled animals often suffer from stress, dehydration and starvation, and many die in transit.

“We have been working with DAFF to test and validate wildlife 3D X-rays and algorithms, both of which have been proven to be highly effective and lead to many important detections. .”
