Las plantas construyen dunas pero pueden acelerar la erosión durante tormentas fuertes
Cuando las olas golpean las dunas con vegetación, se forman áreas anegadas frente a las plantas, lo que facilita que la arena sea arrastrada por la corriente más fácilmente. Sin embargo, las plantas aún son necesarias para formar las dunas en primera instancia.

Scientists Discover a Way of Forming Suspended Layers of Sediment
Laboratory experiments suggest that underwater gas eruptions—due to the venting of gas hydrates, for example—could trigger the formation of layers of suspended sediment in the ocean.

Plants Build Dunes but Can Speed Erosion During Severe Storms
When waves hit vegetated dunes, waterlogged areas form in front of plants, making for sand that’s easier to wash away. But you still need plants to form dunes in the first place.
