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.
