Alien plants are the scourge of natural habitats and the greatest threat, second only to habitat destruction. They grow quicker than their natural counterparts, consume more water and have no natural predators which allow them to grow completely unchecked.
Having gained a foothold, alien plants choke the indigenous flora and leach nutrients from the soil. The threat of uncontained veld fires increases as many of the alien plants burn at a higher temperature than the indigenous grasses, causing trees and other vegetation, which would normally have remained unharmed, to catch fire and burn.
Regular and consistent programs are run to locate and remove alien plants from the environment. Local communities are provided with employment which, in turn stimulates the local economy.
