Who we are

The C·I·B is an inter-institutional Centre of Excellence established in 2004 within the DST-NRF Centres of Excellence Programme. Its members undertake research on the biodiversity consequences of biological invasions, largely through post-graduate student training. The principal aims of the Centre's work are to reduce the rates and impacts of biological invasions by furthering scientific understanding and predictive capability, and by developing research capacity.

The C·I·B has its physical home at the University of Stellenbosch, but comprises a network of senior researchers and their associated postdoctoral associates and graduate students throughout South Africa. Find out more about us.

Highlighted Paper

Port Jackson impacts the restoration of Protea repens long after its removal

Mlungele Nsikani in the greenhouse where the Sugarbush growth trials took place

The growth of our native Sugarbush (Protea repens) is not negatively affected by the legacy of altered soil chemistry after the clearing of invasive Port Jackson (Acacia saligna). This was the finding of a recent study by C·I·B PhD student, Mlungele Nsikani, and C·I·B researchers, Brian van Wilgen, Sven Bacher and Mirijam Gaertner.

For Students

In support of our vision, we are offering bursaries to students who are studying towards an Honours, Masters or Doctoral degree in biodiversity, environmental sociology or invasion biology. Click on links to the left under “Student & Research support” to find out more about the support and bursaries that are on offer.

EnviroKids: Understanding alien plants and animals in South Africa

The C·I·B has joined forces with the Wildlife and Environmental Society of South Africa (WESSA) in putting together an issue of the EnviroKids magazine, themed “Understanding alien plants and animals in South Africa.” This issue tackles the history of how aliens arrive from other places and what it means when they invade, highlighting certain examples of plants and animals. The content of Envirokids supports the national curriculum and serves as an educational resource for learners, parents and teachers.

C·I·B contributes to articles in The Conversation

The Conversation Africa is running a series on invasive species. Read the articles to find out how invasive species are affecting Africa and what measures are being used to reduce their impact.

Detecting and Responding to Alien Plant Incursions

by John R. Wilson, F. Dane Panetta and Cory Lindgren.

Ecologists, land managers and policymakers continue to search for the most effective ways to manage biological invasions. In a new book by C·I·B researcher, John Wilson and colleagues, they explore how to detect and respond to alien plant incursions.
