Academic Papers

These are academic papers relating to invasive species in South Africa. They include current research and projects such as biological control, invasive species traits, invasion biology and the detrimental effects invasive species have on biodiversity, water resources and the economy. They are listed according to year in which they were published.

The global distribution of bamboos: assessing correlates of introduction and invasion

There is a long history of species being moved around the world by humans. These introduced species can provide substantial benefits, but they can also have undesirable consequences. We explore the importance of human activities on the processes of species dissemination and potential invasions using the Poaceae subfamily Bambusoideae (‘bamboos’), a group that contains taxa that are widely utilised and that are often perceived as weedy.

Aliens in the nursery: assessing the attitudes of nursery managers to invasive species regulations

The horticultural industry is recognised as a major pathway for the introduction and spread of invasive alien plants (IAPs). The Conservation of Agricultural Resources Act (CARA) of 1983 (Act No. 43 of 1983) listed and categorised invasive species with an aim to curb their spread.

Assessing and managing the threat posed by Epipremnum aureum in
South Africa

The predictive success of risk assessments is still largely a function of invasiveness elsewhere. Therefore, species
that are invasive elsewhere should be prioritised for management, and where possible eradicated.We set out to
investigate the threat posed by the alien climber Epipremnum aureum (Araceae) and assess techniques for controlling
the spread of the species in South Africa.

Impact assessment with different scoring tools: How well do alien amphibian assessments match?

Classification of alien species’ impacts can aid policy making through evidence based listing and management recommendations. We highlight differences and a number of potential difficulties with two scoring tools, the Environmental Impact Classification of Alien Taxa (EICAT) and the Generic Impact Scoring System (GISS) using amphibians as a case study. Generally, GISS and EICAT assessments lead to very similar impact levels, but scores from the schemes are not equivalent.
