Which sand dune migration outcome arises because vegetation anchoring fails?

💡 Explanation

Increased erosion occurs if vegetation dies which inhibits *vegetative stabilization*, making the dune unstable. This leads to massive sediment transport and avalanches down the slipface; therefore massive avaalanche, rather than decreased sediment and erosion changes within playas.
