The beach of Griells in l’Estartit has been the scene of an extraordinary event: a loggerhead turtle (Caretta caretta) laid 105 eggs in the sand along our coastline. At Club Nàutic Estartit, we celebrate this event as a milestone that highlights the ecological richness of our natural environment and reinforces the need to protect marine biodiversity. The presence of loggerhead turtles on our coastline is a positive indicator of environmental health and encourages us to continue working towards a more vibrant and sustainable sea.

Immediate protection and coordinated action

Once the presence of the animal was confirmed, the area was quickly cordoned off to protect the turtle and avoid any disturbance. Local Police officers played a key role: they managed to hold the animal in optimal cool conditions until the arrival of specialized teams.

Rural Agents, technicians from the Montgrí, Medes Islands and Baix Ter Natural Park, as well as researchers from the BETA Technological Center at the University of Vic, were mobilized. Veterinarians from the Marine Animal Recovery Center (CRAM) and technicians from the University of Barcelona also intervened to carry out a full health examination of the turtle, including an ultrasound, microchip placement, and satellite transmitter attachment.

Scientific monitoring and nest preservation

Thanks to the device installed, it will be possible to monitor the turtle’s movements via satellite, identifying key habitats and potential interactions with human activities such as fishing. This type of information is essential for marine biodiversity conservation projects.

The nest, which contained 105 eggs, will be moved approximately 50 meters inland, toward the dune near Ter Vell, in order to protect it from potential storm surges and ensure the safety of both the eggs and beachgoers. Part of the eggs will be kept in an incubator to maximize reproductive success under different environmental conditions. The new nest will be monitored daily, with special attention to sand temperature.

A record summer for sea turtles on the Costa Brava

The nesting in l’Estartit is already the fourth recorded this summer on the Costa Brava, following those in l’Escala, Sant Feliu de Guíxols, and Platja d’Aro. Across Catalonia, ten nests have already been documented in total, equaling the record set in 2023, according to data from the BETA Technological Center. Everything indicates that this season will set a new record for loggerhead turtle reproductive activity along our coastline. Hatchlings are expected to emerge between mid and late September, after an incubation period of around 60 days.

Local Police and wildlife protection teams remind the public of the importance of not approaching or disturbing sea turtles, especially if a potential nest is spotted. In case of observation, it is necessary to call 112 or immediately inform local surveillance services.
