The Drakensberg Escarpment runs north to south almost through the centre of the study area. This creates three distinct physiographic regions, the high interior plateau, the escarpment zone, and the low-lying region, with altitudinal differences from 100 m to 2300 m above mean sea level. The high interior plateau has relatively flat, rolling terrain, suitable for cultivation or pasture; the escarpment zone is mountainous with scarps and steep valley flanks; and the low-lying region has flat rolling terrain, also suitable for cultivation, but requiring irrigation in many areas.

The region is characterised by plains with moderate slopes and mountain or highveld grasslands on deep red to yellow sandy soils, overlying granites, quartzites and basalts (Ref 2) | ||||||||||||||||||||||
