Invasive alien plants have a negative impact on the ecological integrity of our natural systems, the productive potential of land, the intensity of fires, flooding, erosion, the health of estuaries, water quality and quantity and the livelihoods of communities who depend on these life-support systems.
One of the most substantial impacts of invasive alien plants in South Africa is their impact on water availability and increased fire risk. It is estimated that they create a loss of nearly 695 million m³ in water yield each year and fires in invasive flora can burn up to 10 times hotter than indigenous vegetation.
