Ecosystem services flow interregionally between sending and receiving regions and their consumption can have impacts on ecosystems in distant regions. Global trade of wild species comprises a multitude of ecosystem services. We identify ecosystem service flows provided by traded species and delineate main sending and receiving regions through species range maps, based on bilateral trade entries in the database of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) from 2014 to 2018. We found that 65% of species represent the service class ‘Science’ (1378 species), 14% ‘Decoration and Pets’ (293), 9% ‘Entertainment’ (188), 4.7% ‘Conservation’ (96), 4.6% ‘Education’ (95) and 2.7% ‘Medicine’ (54). Sending regions are predominantly located in the ‘global South’ and receiving regions in the ‘global North’. Of the traded species 12.3% are threatened and 83.9% may become so without regulation. Of the main sending regions 24.1% are protected. Results show that main sending and main receiving regions differ depending on the ecosystem service. By linking actual trade data from CITES with different types of services, traded service-providing species can be directly assigned to service classes. Through the novel approach of identifying sending regions based on species-specific range maps, the study enables spatial analyses down to a 100x100km scale within countries and regions globally for more targeted conservation actions.

生态系统服务在发送区域和接收区域之间跨区域流动，它们的消耗会对遥远区域的生态系统产生影响。全球野生物种贸易包括多种生态系统服务。我们根据 2014 年至 2018 年 CITES（濒危野生动植物种国际贸易公约）数据库中的双边贸易条目，确定贸易物种提供的生态系统服务流，并通过物种范围图划定主要发送和接收区域。我们发现 65% 的物种代表服务类别“科学”（1378 种）、14% 的“装饰和宠物”（293）、9% 的“娱乐”（188）、4.7% 的“保护”（96）、4.6% “教育”（95）和 2.7% 的“医学”（54）。发送地区主要位于“全球南方”，接收地区主要位于“全球北方”。在交易物种中，12.3% 受到威胁，83.9% 可能在没有监管的情况下变成威胁。在主要发送区域中，24.1% 受到保护。结果表明，主要发送区和主要接收区因生态系统服务而异。通过将来自 CITES 的实际贸易数据与不同类型的服务联系起来，可以将提供贸易服务的物种直接分配到服务类别。通过基于物种特定范围图识别发送区域的新方法，该研究可以在全球国家和地区内进行小至 100x100 公里的空间分析，以进行更有针对性的保护行动。通过将来自 CITES 的实际贸易数据与不同类型的服务联系起来，可以将提供贸易服务的物种直接分配到服务类别。通过基于物种特定范围图识别发送区域的新方法，该研究可以在全球国家和地区内进行小至 100x100 公里的空间分析，以进行更有针对性的保护行动。通过将来自 CITES 的实际贸易数据与不同类型的服务联系起来，可以将提供贸易服务的物种直接分配到服务类别。通过基于物种特定范围图识别发送区域的新方法，该研究可以在全球国家和地区内进行小至 100x100 公里的空间分析，以进行更有针对性的保护行动。
