Briefings

A study by Asclepias and CASTEL VOLTURNO, Italy, and BARCELONA, Spain, documents the first recorded nesting of loggerhead sea turtles (Caretta caretta) in the Mediterranean's western basin, specifically on Italian shores near Naples. This marks a significant shift from historical nesting patterns concentrated in Greece, Turkey, and Cyprus, where the species historically nested. The research highlights the species' vulnerability to extinction and the ecological impact of this expansion, which has prompted local beach resorts to adopt sand-sharing protocols to manage turtle nesting sites.

Key points

• Loggerhead sea turtles (Caretta caretta) are listed as vulnerable to extinction by the IUCN and spend roughly two decades maturing at sea before returning to land to lay eggs.
• Historically, Mediterranean nesting was concentrated in the eastern and central basins (Greece, Turkey, Cyprus), but over the past five decades, increasing numbers of nests have appeared in the western basin, including Italy, France, and Spain.

Context

This article documents the first recorded nesting of loggerhead sea turtles in the Mediterranean's western basin, specifically on Italian shores near Naples. This shift marks a significant ecological change from historical patterns concentrated in Greece, Turkey, and Cyprus, where the species historically nested. The study highlights the species' vulnerability to extinction and the ecological impact of this expansion, prompting local beach resorts to adopt sand-sharing protocols.

Limitations

The evidence is limited to a single field observation from July 2026 in Castel Volturno, Italy, and does not include data on the total number of nests, geographic spread, or long-term population trends. The study relies on drone observations and local reports, and the specific impact of this nesting on local beach resorts is inferred rather than measured.
