Mlawula Nature Reserve - Soils |
The soil types found within the reserve vary greatly. Much of the area consists of rock outcrops and stony ground (raw mineral soil) but in the Ndzindza area, the soils found consist of either grey sand or sandy loam on hard rock (Lithosolic). In contrast, the Siphiso Valley area holds mainly brown to black loams or clay (Vertisolic). Grey, black and red clays (Vertisolic) as well as deep red, yellow and orange loams (Fersialitic) have also been recorded in the area. The larger watercourses are flanked by narrow strips of colluvial and alluvial soils.
Soil erosion is a serious problem in places. The Siphiso valley contains large areas that have been subject to sheet, rill and gully erosion as a result of overgrazing. Badly drained roads also cause erosion in some areas.
