Addressing uncertainty in impact assessments for alien species

Impact classification schemes for alien taxa are becoming more prominent as the threats posed by biological invasions increase. A recent study found that despite a high variety of uncertainties occurring in impact assessments, some of which cannot be eliminated easily, communicating their existence, cause and variety can lead to more useful and reliable outcomes of impact assessments.

Insights into the future distribution of invasive alien plants in the Heuningnes catchment

A recent study by former C∙I∙B student, Bongolethu Mtengwana, demonstrated the advantage of combining different species distribution models to identify areas that are at risk of future invasions by Invasive Alien Plants (IAPs).

Alien pest of wheat and maize could pose a threat to South Africa

Alien pests of agriculture cause billions of Rands’ worth of damage to South African crops every year. Knowledge on which pests could pose a threat in the future is vital to inform South Africa’s biosecurity.

Taxonomy and introduction histories of non-native Prosopis populations for their effective management

Trees in the genus Prosopis (known as mesquite) have been widely planted outside of their native ranges in many countries, and many species are now among the world’s worst woody invasives. The genus contains 44 species from the Americas, South West Asia and North Africa, and several have become major problems in South and East Africa.
