The small Indigo Valley Salinity Province has been extensively cleared and the natural vegetation replaced by dryland annual pasture. Saline discharge sites mainly occur at the ‘break-of-slope’ between the steep upper-slopes and the less steep mid-slope region and in low-lying depressions on the valley floor associated with the shallow bedrock. |
