While the pangolin’s thick overlapping scales protect it from predators such as lions, this animal is an easy mark for illegal wildlife traffickers. Image courtesy of the Tikki Hywood Foundation, Zimbabwe.

Acting on a tip, Nigerian customs operatives raided an apartment in the southwest city of Ikeja in February. Inside, they found some 4,400 pounds of pangolin scales, and 218 ivory tusks—and arrested a Chinese suspect, Ko Sin Ying, who lived there.

A few months earlier, at the other end of a well-worn trade route, Chinese customs officials made the largest-ever seizure of pangolin scales in the port of Shenzhen. They discovered an “empty” shipping container that had come in from Africa—stuffed with 13 tons of scales. They were packaged in bags that camouflaged their true contents beneath a veneer of charcoal. That haul had killed an estimated 20,000 to 30,000 animals, each about as big as a medium-sized dog.

The global poaching crisis has induced large segments of the conservation community to call for far tougher law enforcement. Many look to policing lessons from decades of counter-narcotics efforts for solutions.

“The same criminals that are trafficking in drugs, guns, and people, traffic in wildlife,” said Christine Dawson, the director of the Office of Conservation and Water at the U.S. Department of State, at a recent event in the Wilson Center’s “Managing Our Planet” series. Experts from Vulcan Productions and Brookings Institution joined Dawson to discuss the links between national security and wildlife trafficking, which is now the fourth largest transnational crime in the world, and to mark recent legislative successes and innovative tools.

For the past few years, much of my work as a journalist has focused on wildlife and environmental crime. I’ve covered poaching busts and seizures of everything from pangolin scales and big-cat skins to rhino horn, live turtles and songbirds. I’ve reported on the Asian, African and South American markets that sell animals live, dead and in parts, and about the consumers that drive this black-market trade. I’ve written about China, the largest consumer, where many endangered species products are luxury items bought by the wealthiest and most influential as a way to flaunt power and gain prestige. I’ve also explored the trade here in the United States — the world’s second largest consumer. I covered the ubiquitous bird trade in Latin America, where ownership of pet parrots and other birds is so rampant that few realize these animals are endangered, or that it’s against the law to buy or keep them.

In the dead of night on February 15, gunshots blasted the guards into action in India’s Kaziranga National Park. Rangers stationed in a nearby camp quickly spread out, searching for the shooters under the light of a nearly full moon – to no avail.

Rhino horn is the most valuable illegally traded wildlife product in the world, more expensive per pound than either gold or cocaine and much more valuable than elephant ivory. With as few as 25,000 wild rhinos left in Africa, conservationist and law enforcement fight a constant battle with criminal syndicates seeking to kill rhinos and sell their horns to wealthy consumers abroad, many in Asia.

From 1990 to 2013, the notorious tiger poacher Kuttu Bahelia and his extended family – brothers, uncles, and their wives and children – reportedly killed hundreds of tigers and leopards in the tiger-rich Indian states of Maharashtra and Karnataka, according to law enforcement informants and media reports. “Even if half that [estimate] is correct, it is still a very significant number,” says Belinda Wright, who directs the non-profit Wildlife Protection Society of India (WPSI).

At this year’s International Union for Conservation of Nature (IUCN) World Conservation Congress, more than 10,000 scientists, activists, and leaders from around the world committed to finding “nature-based solutions” to reversing environmental declines and securing a healthy, livable planet.
