Data were extracted from alien species databases on alien species in South Africa, on their pathways and dates of introduction, their regions of origin, South African distribution and invasion status. These data were used to assess the information content of South African alien species databases and to assess the introduction pathways of alien species in South Africa. The stowaway pathway for alien species was then assessed in more detail, and the role that shipping plays in the introduction of stowaway organisms to South Africa was evaluated. Finally, a simple, rapid and inexpensive method for developing invasive species watch lists was created and was tested using South Africa as a case study.
