Which process causes crescent dune migration to stall?

💡 Explanation

Vegetation prevents grain flow via biostabilization, anchoring the slipface; therefore, the dune's migration halts, rather than being driven by wind or changes in sand saltation rates, assuming there is persistent vegetation taking root.
