During the current season, storms that produce strong waves are much more common. Last year, the seawater flooded the La Llana beach ecosystem, even managing to reach the salt pans. In the past, this dune system has already been reinforced with banquettes of Posidonia oceanica. In addition, efforts have been made to install sand collectors and plant native species in order to improve the consistency of the dune system. It is necessary to reinforce the dunes with banquettes of Posidonia oceanica periodically, as the sea gradually pulls this vegetation away.
These sand dunes do in fact contain protected priority habitats, but they also act as shields, protecting the salt pans from the intrusion of seawater from the Mediterranean Sea, in addition to being a natural sand reservoir for the beach.
