South Africa has a long history of non-native species introductions and the primary reasons for these introductions include provision of food and raw materials, biocontrol, ornamental and recreational purposes. Of concern is that despite the considerable socio-economic benefits derived from some of the non-native species, they can also cause adverse ecological impacts in recipient areas.  As a result non-native species with a high societal value are now considered to be conflict species where there is a direct dissension between attaining biodiversity goals and human interests.  Yet, despite many cases of conflicts that have arisen, there has been no systematic review of the common principles/trends in conflicts across taxa. This paper proposes to systematically review cases of conflicts in invasive species management in South Africa and provide a conceptual framework to identify types of conflicts, ways in which conflict has been avoided, and where it has not.
