This information is lists of alien species regulated in South Africa under the National Environmental Management: Biodiversity Act in an accessible form. The first worksheet is essentially metadata. The second worksheet is intended to be a link between any taxa listed or proposed for listing and various taxonomic backbones. The third worksheet is intended to provide a list of taxonomically verified names linked to the current lists. The other worksheets link to particular versions of the regulations (including version sent for public comment that were never published), the intention is for this to be an exact copy (including formatting), please report any inconsistencies between this and the published version to john.wilson2@gmail.com, but before doing so please double-check that what is presented here, is not how it is presented in the lists themselves. The data were extracted by John Wilson at various dates from pdfs in the government gazette, contact john.wilson2@gmail.com For further details please see: Wilson JRU, Kumschick S (2024).
