As few as three major criminal groups are responsible for smuggling the vast majority of elephant ivory tusks out of Africa, according to a new study.
Researchers used analysis of DNA from seized elephant tusks and evidence such as phone records, license plates, financial records and shipping documents to map trafficking operations across the continent and better understand who was behind the crimes.
The study was published [February 14] in the journal Nature Human Behavior.
Conservation biologist Samuel Wasser, a study co-author, hopes the findings will help law enforcement officials target the leaders of these networks instead of low-level poachers who are easily replaced by criminal organizations.
“If you can stop the trade where the ivory is being consolidated and exported out of the country, those are really the key players,” said Wasser, who co-directs the Center for Environmental Forensic Science at the University of Washington.
Africa’s elephant population is fast dwindling. From around 5 million elephants a century ago to 1.3 million in 1979, the total number of elephants in Africa is now estimated to be around 415,000.

“Confronting these networks is a great example of how genetics can be used for conservation purposes,” said Brian Arnold, a Princeton University evolutionary biologist who was not involved in the research.
