Abstract

At least 39,215 alien species and more than 37,000 established alien species have been recorded worldwide and occurrences of established alien species have been reported from all countries and all ecosystems globally (established but incomplete). Among these, 5,256 species have been classified as invasive according to the database underlying this chapter (established but incomplete). The distribution of established alien species shows marked hotspots of high species numbers, mostly located in North America, Europe, and Australasia, but also in individual African and Asian countries (established but incomplete). However, low data availability, particularly in Africa and Central Asia, suggests that many more unrecorded established alien species are extant but not reported due to a lack of monitoring and data integration (established but incomplete). Thus, the reported numbers of alien, established alien, and invasive alien species are likely severely underestimated (well established).
