The extensive road network in the city is vitally important for connecting suburbs, allowing people to move around and transport products across the city. In addition to this very important role the road network also play an integral part in the movement of invasive plants. Roads are "pathways" along which invasive plants are spread from one part of the city to the other. The seeds of plants may be transported by vehicles, people, animals and cyclists utilizing the roads.
Another very important vector of invasive plant movement along road verges is lawnmowers or brush-cutters. The city has to maintain road verges and part of the maintenance activities include scheduled mowing and controlling invasive weeds along the road verges. Teams are currently busy on the road verges in the Far South which includes amongst others Kommetjie Rd, Ou Kaapse Weg, Silvermine Rd, Chapmans Peak drive, Glen Cairn Express way, Plateau – Main - and Red Hill roads. This work will be repeated every six to eight months to ensure the plants are removed before establishing large populations. Controlling invasive plant on other road verges across the city will occur throughout the year.
