If you walk along the shore of our beaches, you may find piles of dry leaves that come with the waves. They are not algae, but remains of Posidonia oceanica, a unique marine plant of the Mediterranean and a real natural treasure that we must protect.

A regulation for its conservation
To ensure the protection of posidonia and the coastline, in May 2024 the Generalitat Valenciana approved the Manual of Good Practices on the removal of posidonia remains, in compliance with Decree 64/2022. This document determines in which beaches, seasons and conditions the remains that reach the shore can be removed.

In Dénia, this affects:
