Forensic science is getting higher yearly, and even animal conservationists are harnessing it to cease unlawful poaching and buying and selling. In findings printed as we speak within the journal Nature Human Behaviour, College of Washington scientists define their work with the U.S. Division of Homeland of Safety to uncover a global community of elephant ivory traffickers—all because of DNA testing.
The brand new examine, which examined greater than 4,000 African elephant tusks seized over 17 years in 12 African nations, reveals the grave extent of unlawful ivory buying and selling internationally. However it additionally offers some insights that would assist authorities shut down these commerce networks and bolster efforts to guard elephant species in Africa.
“These strategies are displaying us that a handful of networks are behind a majority of smuggled ivory, and that the connections between these networks are deeper than even our earlier analysis confirmed,” Samuel Wasser, a UW biologist who led the brand new examine, mentioned in a press release.

Wasser and his crew aren’t new to this work—they launched findings in 2018 that used genetic testing to determine tusks that got here from the identical elephant however have been separated and smuggled into totally different shipments earlier than being seized. Armed with the information of how shipments in numerous components of the world got here from the identical origin level, authorities have been capable of pin down well-liked unlawful commerce routes involving three African ports (Mombasa, Kenya; Entebbe, Uganda; and Lomé, Togo.)
The brand new examine is a major step up from there. Wasser and his crew used genetic testing to determine not simply if tusks got here from the identical elephant, but additionally in the event that they got here from the identical household of elephants—be they mother and father and offspring, siblings, half-siblings, or different relationships.
By means of testing of greater than 4,320 tusks from 49 shipments seized from 2002 to 2019, the crew confirmed that the majority poachers are searching the identical elephant populations 12 months after 12 months, and that it’s doubtless the identical handful of cartel networks which can be buying and smuggling these tusks out of Africa.

A deeper evaluation additionally confirmed how these cartels shifted the majority of their operations from Tanzania within the early 2000s to Kenya and Uganda. Angola and the Democratic Republic of Congo are additionally newer hotspots for ivory smuggling, and there’s been a brand new shift of unlawful exports from Togo to Nigeria.
Wasser expects the brand new information to assist make it simpler to prosecute unlawful ivory merchants and nail down their duty for a broader array of seizures, which might result in extra extreme penalties.
“By linking particular person seizures, we’re laying out entire smuggling networks which can be making an attempt to get these tusks off the continent,” mentioned Wasser.
