The spread of the new coronavirus has stalled economic activity, halted travel and locked down some cross-border trade. Another sector that’s feeling the pinch is criminals trafficking illegally in poached wildlife.

“Security is too heavy at the border. Products can’t go out,” said a person in Vietnam involved in the trade. That person spoke to an undercover investigator who was involved in a new report on the state of the illegal wildlife trade.

The pandemic has prevented organized criminal gangs in Southeast Asian countries from moving large quantities of ivory and pangolin scales into China. But any limits on the illegal wildlife trade are likely to be temporary.

“There’s too much money to be made from these products, and there’s too many people involved for this to have a significant long term impact,” said Sarah Stoner, a co-author of the report and director of intelligence at the Wildlife Justice Commission, an international foundation based in The Hague, Netherlands, that works to dismantle illegal wildlife trade.
