The Wildlife Justice Commission said a threat assessment on the state of rhino horn trafficking in the past decade showed that much was needed to fight the trade via law enforcement, policymakers and conservation. The assessment found that over the last decade, six countries dominated the supply chain as source, transit and destination locations and that a third of rhino horns were smuggled unconcealed, suggesting a potential reliance on corruption to move shipments along the supply chain. They found that large amounts of harvested horns have been diverted from legal stockpiles into the illegal trade, with criminal groups exploiting stockpile systems to access harvested rhino horns for trafficking. Ten percent of cases were associated with various crimes such as firearms and drugs.
