Posidonia oceanica meadows play a fundamental role in the conservation of marine biodiversity, however, in many coastal enclaves these meadows are seriously affected.

Posidonia oceanica meadows play a fundamental role in the conservation of marine biodiversity, however, in many coastal enclaves these meadows are seriously affected.

Among the causes of the deterioration of this ecosystem are water pollution, excessive urbanization of the coast and alterations in sedimentation dynamics. The control networks of the Posidonia oceanica meadows are a key element for the knowledge, protection and management of this marine phanerogam.

Due to the importance of conserving these ecosystems, it is essential to deepen the study of their state of conservation. This project aims to integrate the different control networks that are already operating independently on the Spanish coast, with the aim of designing a sampling methodology common to all the networks and obtaining comparable results.
