Challenges in documenting trade in non CITES-listed species: A case study on crocodile skinks (Tribolonotus spp.)

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) aims to ensure that international trade does not further endanger species already threatened by trade. While the scale of trade in CITES-listed species is relatively well documented, trade in non-CITES-listed species is usually only collected when it concerns physical or online market surveys. We explore the challenges faced in monitoring trade in non-CITES-listed species based on available data. We found that data available on non-CITES-listed species are confusing, irregular, and far from complete and can only provide an indication of the actual quantities traded. In addition, it is subjected to the willingness of individual countries to provide or record data. Limited availability of data on trade in non-CITES-listed species can impede conservation efforts, as the actual level of trade remains unknown and concerns are often undetected.
