Designation
It is protected for the habitat types and species of Annexes I and II of the Habitats Directive (92/43/EEC) as a Site of Community Importance; member states designate such sites as Special Areas of Conservation (SAC).
| Code | Type | Area | Designated (EEA) | Name in the EEA register |

Legal basis: Habitats Directive (92/43/EEC). The register name is the one the EEA publishes.

Works and permits in the site
Works and plans that could significantly affect a Natura 2000 site need an appropriate assessment of their effects under Article 6(3) of the Habitats Directive (92/43/EEC). In Greece this is the Special Ecological Assessment (Ειδική Οικολογική Αξιολόγηση, ΕΟΑ) under law 4014/2011. The Natural Environment and Climate Change Agency (ΟΦΥΠΕΚΑ) is responsible for managing Natura 2000 sites, through the protected-area management bodies.
This page is not legal advice and does not say what is allowed on a particular property. Each site's rules are set in the official texts; for a property or a project, ask the competent authority. Natura 2000 at the European Commission.
How the numbers were counted
The boundary is the Ministry's (YPEN geoportal). The code, name, area, date of designation, habitat types and species are from the EEA's Natura 2000 database (2024 release, fetched 8 Oct 2026). Habitat cover is what the member state reports; where the EEA gives an "unknown" value (9999) or one larger than the site, it is not shown. The EEA gives the marine part only as yes or no, not as a share, and we do not use the "quality and importance" text of the data form. The EEA data is licensed CC BY 4.0 (copyright holder: the European Commission's Directorate-General for Environment). The Greek and English names of sites and species, and the Wikipedia article titles, are Wikidata's (CC0).
Municipalities come from sample points inside the boundary: one is named when it holds at least 5% of the points that fall on land. For a purely marine site the nearest coastal municipality (within 60 km) is named. The settlements, beaches and sights are those that have a page on this site; municipal boundaries and island outlines are from OpenStreetMap.
