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.

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.
