“This shows how serious the problem is, and how we need to continue to attack this problem from many different angles: enforcement, forensics, education.” Poaching has been soaring in the past decade.A recent report said that poachers killed off nearly a third of the savannah elephants in Africa from 2007 to 2014, leaving only about 352,000 of the animals.Confirming the age of those pieces, however, relies on proper documentation.Traders in illegal ivory sometimes use this clause as a cover, claiming that their wares are older than they really are.To figure out how old the tusks were, Uno’s team measured how much of a specific type of carbon, carbon-14 (or C-14), was in the ivory.C-14 was created in large quantities by nuclear weapons testing in the 1950s and ‘60s.In China, where ivory is culturally valued and the black market is rampant, politicians have promised to crack down on illegal trade, but many are skeptical of this promise.In today’s study, Uno and his team analyzed 231 tusks seized in nine countries — from the Philippines to Thailand to Kenya — from 2002 to 2014.

Almost all the world’s illegal ivory comes from elephants that have been recently killed, researchers say.

Demand for elephant ivory and other illegal products derived from endangered animals has grown in Asia in recent years, opening a fresh battleground in the struggle against illegal ivory.

Bans usually allow the sale of ivory that was legally acquired prior to 1976, including heirloom or antique pieces.

The answer is not long at all, which suggests there are very well developed and large networks for moving ivory across Africa and out of the continent.'Thure Cerling, the study's first author and a professor of geology and geophysics at Utah, said: 'Apart from the actual killing, there's the trade on the ground before it gets to ports, the actual shipments through shipping containers, and then the problem of the demand side.

This additional information can be helpful to people trying to address those issues.'Despite efforts to stop the ivory trade, poaching claims an estimated 8% of African elephants each year, or around 96 elephants per day.
