Criteria for inclusion

Two criteria were used in selecting items for the list: * An invasive species' "serious impact on biological diversity and/or human activities," and * That species' "illustration of important issues surrounding biological invasion". According to the ISSG, "only one species from each genus was selected." However, the renaming of '' Clidemia hirta'' now implies two ''Miconia'' species in the list.


List of species

This list has been updated to reflect later changes in taxonomy, to ensure alphabetical order of genera, and to remove apparent errors. Common names may be ambiguous.
