There is growing concern that Nigeria, in recent years, has become a primary transit hub for several illicit wildlife and forest products. The United Nations Office on Drugs and Crime (UNODC) stated that Nigeria is notorious in particular for the global illegal trade in pangolin, sourced primarily from Central Africa, "in spite of efforts by the National Environmental Standards and Regulations Enforcement Agency (NESREA), the enforcement authority responsible for the protection of endangered species of wildlife in Nigeria." According to UNODC's recently launched World Wildlife Crime Report 2020, in 2019 alone, at least 51 tons of pangolin scales seized globally originated from Nigerian ports compared to only two tons in 2015. "Indeed, more than half of all seizures of pangolin scales worldwide could be traced back to Nigeria in 2019." A statement issued by UNODC said, "Moreover, from around 2011, great volumes of rosewood, locally known as "kosso", were exported from Nigeria to Asia. In October 2018, the CITES Standing Committee recommended that parties suspend commercial trade in kosso from Nigeria until the country carries out a non-detriment findings assessment for trade in the species. "Data further suggest an increasing role of Nigeria in the illicit ivory trade. Despite a global decline in trafficking in ivory since 2011, Nigeria has been identified in a growing number of incidents as part of the illegal trade chain, with 5,629 kg of ivory being seized in 2009-2011, compared to 11,769 kg in the period 2012-2014, to 12,211 kg in the period 2015-2017."
