DID YOU KNOW?
The Kouga area provides 22% of Port Elizabeth's water supply. 98% is covered in natural vegetation but it loses almost 4% of its water to invasive alien trees.
The Kouga area is home to the high mountains of the Cape Fold belt formed by the Table Mountain sandstone, a huge aquifer system that extends from Cape Town to Port Elizabeth. The Table Mountain Aquifer System, stores water underground and acts as one of nature's hidden dams.
Supplies water to
Alien Invasive Vegetation
Invasive alien trees that have spread through large parts of our country consume more than 2.9% of available water resources. In some catchments, water losses are higher than 25%. These losses contribute to biodiversity loss by crowding out indigenous species, devastating surrounding ecosystem.
Climate change is predicted to exacerbate risks associated with water scarcity and quality. Models show that the western parts of the country will receive less rain, whereas the central and eastern areas will receive more variable rainfall with more intense rainfall events.
Fires are a part of the natural lifecycle of the Fynbos, savannah and grasslands but a higher frequency of fires doesn't allow enough time for natural ecosystems to recover. The impact is exacerbated by the presence of invasive alien trees that burn hotter and longer, causing greater damage to property and the environment. Higher intensity and frequency of fires means that precious soil is eroded and more easily washed away.
