Rock shield (natural)

This method is highly efficient with a low initial cost but moderately hard to implement.

It has a low maintenance requirement with a long longevity, although limited co-benefits and may not be easy to integrate into other methods.

Will not reduce dust over short term and may take years to be an effective to dust entrainment.

Depends on the nature of the soil and requires the presence of cobbles and small stones in the soil to form the rock layer after wind has removed the sand and dust.
