The expanded subset was obtained through the ‘expansion’ of the suitable subset using the ‘invacost’ R package (Leroy et al., 2022). The criteria used for generating the conservative subset were based on the ‘Implementation’ (observed versus potential costs) and ‘Method_reliability_final’ (high versus low-reliability costs) fields of the InvaCost database (Appendix 1, ‘Descriptors’ tab). The number of taxa includes both individual species and undefined species aggregated at the genus level. Costs are expressed in 2017 US$.
