Why is it important to know which plants are invasive on your farm and why you must control them?

Invasive species are not indigenous to South Africa or a specific region and are therefore intruder species. The biggest concern regarding invasive alien plants is the large amount of ground water they consume which could rather have been used for irrigation of crops or for direct human consumption.

It is important to note that it is mandatory to control the invasive plant species on your farm and that failure to do so could have negative consequences. Before a farmer can sell his/her farm, the buyer of the farm must be notified if there are any invasive species on the property (NEMBA (2004): Chapter 5, Part 2, page 60, 73 (2)). If he does not comply with this, a fine could be issued.
