Benidorm’s Posidonia Seagrass Meadows Show Positive Health Trend

 

Benidorm / 9 January 2026

 

The Posidonia oceanica seagrass meadows along the coast of Benidorm are in a favourable state of health, according to the latest annual report by the Institut d’Ecologia Litoral, carried out as part of the Posimed project.

 

The findings were announced by the Councillor for Beaches and the Environment, Mónica Gómez, who confirmed that the study shows “good overall condition, a positive trend in density data and stable coverage levels” across the monitored areas.

 

The report is based on measurements taken at five monitoring stations along the Benidorm coastline: two in Poniente (covering both shallow and deeper areas) and three located in Levante, Mal Pas and Cala del Tío Ximo. The analysis assessed key indicators including seagrass density, coverage, overall density, regression trends, and fragmentation and conservation indices.

 

Councillor Gómez highlighted the importance of Posidonia oceanica, describing it as “a vast underwater green lung that plays a vital role in maintaining the quality and transparency of bathing waters, provides shelter and breeding grounds for marine species, and helps protect the coastline from erosion.”

 

She added that Posidonia is “one of Benidorm’s most valuable yet least-known environmental resources,” reaffirming the City Council’s commitment to supporting monitoring initiatives such as the Posimed project to ensure the long-term conservation of the seabed.

 

According to the report, the Posidonia meadow begins at a depth of approximately five metres off the beaches of Poniente, Levante and Mal Pas, while in the coves of Tío Ximo and l’Almadrava it develops from depths of around 15 metres.
