A national park in the outer Archipelago Sea protecting a mosaic of thousands of rocky islets, wooded islands, shallow bays and underwater habitats shaped by brackish Baltic water and a long history of traditional settlement.
Saaristomeren kansallispuisto
Why it is protected
Conserve the natural and cultural landscapes of the outer archipelago.
Protect marine, island and coastal biodiversity while enabling low-impact public access.
Habitats and significant life
Habitats: Rocky archipelago, Shallow brackish water, Underwater meadow, Coastal meadow, Islet and skerry.
Significant species: Grey seal, White-tailed eagle, Common eider, Baltic marine vegetation.
Rules and activities
Boating, paddling and hiking are important uses, with seasonal and site-specific protections for wildlife.
Fishing and camping remain subject to Finnish law, park regulations and local restrictions.
Governance
Metsähallitus Parks & Wildlife Finland; Southwest Finland conservation authorities.
Pressures
Eutrophication; Climate change; Invasive species; Boating disturbance.
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.
Ecological Condition

How to read this: Insufficient evidence means the available evidence cannot support a conclusion. It does not mean the MPA is in poor condition.
No single park-wide trend established. Confidence: limited. Regional Baltic pressures are documented, but this review does not translate them into a park-wide health grade.
