The historic marine core around Port-Cros protects clear Mediterranean waters, Posidonia meadows, rocky reefs, coralligenous habitat and coastal fish communities. It is one of Europe’s longest-managed marine national-park areas.
Port-Cros (coeur)
Why it is protected
Maintain natural Mediterranean marine communities around Port-Cros.
Protect seagrass, reef habitats and fish populations through regulated access and use.
Habitats and significant life
Habitats: Posidonia seagrass meadow, Rocky reef, Coralligenous habitat, Sandy seabed, Coastal cliff.
Significant species: Dusky grouper, Brown meagre, Noble pen shell, Red coral, Posidonia oceanica.
Rules and activities
Fishing, anchoring, navigation and diving are governed by detailed marine-core rules and zonation.
Visitors must use current park charts and notices rather than the atlas for legal navigation.
Governance
Port-Cros National Park authority; French State; Maritime authorities and local users.
Pressures
Anchoring; Recreation and diving; Fishing outside protected sectors; Invasive species; Marine heatwaves.
Protection effectiveness
These dimensions are intentionally separate: a valid designation or active management program does not, by itself, prove ecological recovery.
Habitats and marine life connections
Ecologically related protected areas
These places share documented habitat types or the same ocean region. The relationship is ecological context, not proof of direct connectivity.
Condition and evidence
MLL reports what the available evidence supports. It does not infer ecological health from designation or mapped coverage.
Insufficient evidence
Place-specific ecology and management evidence has been reviewed, but the available indicators do not support a single current ecological trend for the whole protected area.

How to read this: Insufficient evidence means the available evidence cannot support a conclusion. It does not mean the MPA is in poor condition.
Long-running zoned management and ecological monitoring documented. Confidence: moderate. Monitoring supports feature-level interpretation; no universal health score is assigned.
