The north-eastern Wheatbelt is characterised by vulnerable soils such as Wodjil sands, which can sometimes result in wind erosion. The strategic planting of perennial shrubs in high-risk areas has been used to help stabilise fragile sands; either using block plantings, at the exclusion of future cropping opportunities, or more recently widelyspaced shrub belts, which function to slow wind speeds across the paddocks, while allowing normal cropping and pasture rotations in the alleys between.
