Key findings

The greatest window of erosion risk was before vegetation establishment where a large proportion of surface area was exposed to the erosion forces of rain and runoff. This study showed there was little difference in soil erosion rates between slope gradients once a dense sward of buffel grass established on soil plots. Vegetation growth also reduced soluble salt concentrations at the surface of spoil material and reduced the risk of salt movement on site and off site. Where spoils were crusted, poor seedling establishment and vegetation growth was evident. This also resulted in large runoff and erosion rates throughout the study sites.
