A temporary compendium of taxa recorded surviving without deliberate human assistance in the Witwatersrand region (naturalised, including invasive and extralimital, taxa indented). This exists to organise information meant for a number of the articles I intend to create on the biodiversity of Greater Johannesburg. References for each species still upcoming. Ideally I'd still like to, at some point, turn all redlinks into articles.
Very much still a work in progress! As of 20 January 2023.
