New research reveals an innovative wildlife forensics method that uses advanced genetic tools and local DNA databases to help authorities solve complex environmental crimes involving multiple species.

By analyzing real cases of poisoned vultures and poached gazelles, the research proves that even mixed or degraded evidence can be used to identify species, trace their origins, and confirm criminal activity beyond reasonable doubt. This is critical because wildlife crime is a major driver of biodiversity loss worldwide, and the ability to investigate and prosecute these cases effectively is essential for protecting endangered species and enforcing conservation laws.

The work is in the journal Frontiers in Ecology and Evolution.

From poisoned vultures to poached gazelles, wildlife crime scenes rarely look like those on TV. But thanks to the work by Dr. Gila Kahila Bar-Gal at Hebrew University's Koret School of Veterinary Medicine, the odds of catching environmental criminals just got better.

In the study, Dr. Kahila Bar-Gal presents an innovative, integrative approach to wildlife forensics. Her work demonstrates how combining advanced genetic tools with local databases can assist conservation authorities in solving even the most complex environmental crimes involving multiple species, both wild and domestic.

Wildlife crime is not a fringe issue. Ranked among the top five illicit global trades, it contributes directly to biodiversity loss and the decline of already endangered species. In Israel, that includes the critically endangered Eurasian griffon vulture and the mountain gazelles, all of which were central to the forensic cases examined in the study.

"When a vulture is found poisoned or a gazelle is killed out of season, you're not just looking for a suspect鈥攜ou're often dealing with mixed evidence that may include multiple species, some protected, some not," explains Kahila Bar-Gal. "The only way to untangle it is through precise, multi-layered analysis."

Her research showcases three real-life cases involving illegal poisoning and poaching. Each required molecular genetic analysis, including species identification, population assignment, and matching individual samples against both global and local DNA databases. The goal: not just to identify the species, but to prove鈥攂eyond reasonable doubt鈥攖hat a crime against wildlife was committed.

The power of this method lies in its adaptability. It can differentiate between wild and domestic animals in a seized sample, track the geographic origin of a species, and even confirm whether multiple remains came from the same individual.

"Enforcement agencies need fast, cost-effective tools they can trust," Kahila Bar-Gal adds. "Our protocols are designed to be accurate and practical鈥攂ecause saving a species often comes down to solving forensic cases."

This study strengthens the growing field of wildlife forensic science and offers enforcement authorities鈥攆rom park rangers to customs agents鈥攁 new toolkit in the fight against environmental crime.
