US wildlife trade data lack quality control necessary for accurate scientific interpretation and policy application

Abstract

AbstractInternational wildlife trade data are frequently used by government agencies, conservation organizations, and scientific researchers to study and protect species from overexploitation and prevent the spread of invasive species and introduction of zoonotic pathogens. Inaccurate data can lead to mistaken conclusions by researchers, the development of unsuccessful remedial conservation actions, and provide government officials with incorrect views of detrimental trade. The U.S. Fish and Wildlife Service (USFWS) maintains the world's most comprehensive national dataset of legal and illegal international wildlife trade recorded by individual shipments and species in its Law Enforcement Management Information System (LEMIS). Although the importance of LEMIS data is not to be understated, the errors and inconsistencies contained therein have not previously been adequately recognized or studied. Based on firsthand experiences with the creation and application of LEMIS data, this manuscript describes a variety of errors, biases, omissions, and an overall lack of data quality assurance. An independent audit of the LEMIS wildlife trade database and the service's policies, procedures, and protocols for managing this system is needed. Additional recommendations are also offered to develop better management standards and bring greater resources for managing LEMIS, asking the nongovernmental organization and intergovernmental organization user communities to play a role.
