A Simmonds Lumber employee operates a forklift to move DNA timber at the company's timber yard in west Sydney June 29, 2012. Stores are increasingly worried about being duped by a global trade in illegal timber worth billions. Until now, the battle against trade in illegal timber has been waged with regulations and preventive measures, and has not met with much success. Now it is increasingly focused on using the criminal justice system and law enforcement techniques. Industry officials say rapid advances and plunging costs for DNA testing of timber now make it commercially viable for companies trying to meet new regulations in the U.S. and Europe against such practices.
