Australian Acacia species in South Africa: an assessment of the current status of recorded introductions

Australian Acacia species in South Africa: an assessment of the current status of recorded introductions

The history of forestry plantings of Australian acacias in South Africa has been well documented by Poynton (2009).  However, the work is incomplete as it focusses primarily on forestry introductions, and is also in need of updating (most of the work was done in the 1970s). Here we review the status of all introduced Acacia species in South Africa, focussing particularly on species that are less widespread. Biodiversity data from museums and herbaria contain several sources of errors and biases, and, as a result, current data and distribution of many species may be inaccurate and incomplete. It is important to re-evaluate current and historical data from these sources as well as from expert knowledge, in order to supplement recent field survey data and create updated distribution maps of alien species. Assessment of current invasion status will play a major role in determining which management strategies are needed.
