Réserve naturelle nationale de Moëze-Oléron

The Réserve naturelle nationale de Moëze-Oléron is one of the largest nature reserves on France's Atlantic coast, stretching between the island of Oléron and the mainland in the Charente-Maritime department. Protection was granted in two stages: the terrestrial section in 1985, followed eight years later, in 1993, by the maritime section. Together the reserve covers roughly 6,400 hectares, making it one of the most extensive protected areas of its kind in France.

Where exactly is the reserve located?

The bulk of the reserve, around 6,170 hectares, lies within the maritime public domain — tidal flats, mudbanks and shallow waters between the island and the coast. The remaining, much smaller portion, covering about 220 hectares, is on land to the east of the main area, in the Brouage marshes south of the Charente estuary. The commune most closely associated with the reserve, and its administrative anchor point, is Moëze.

Why is this land protected?

The landscape of Moëze-Oléron is dominated by extensive coastal mudflats, wet meadows and salt marshes — habitats typical of the Atlantic shoreline but increasingly rare to find intact at this scale. It is precisely this mosaic of tidal flats and brackish grassland that gives the site its outstanding ecological value, particularly for birds.

Why does the reserve matter so much for birds?

Moëze-Oléron sits along the East Atlantic Flyway, one of the main migration routes used by birds travelling between breeding grounds in the far north and wintering areas in Africa. The reserve functions as a critical stopover — a place to rest and feed for both birds passing through and those that stay for longer periods, including overwintering. Its importance for ornithology is described as national, and even international, underlining its relevance well beyond France's own borders.

Who manages the reserve?

Since 1986, just a year after the site first gained protected status, the reserve has been managed by the LPO (Ligue pour la Protection des Oiseaux), the French bird protection organisation. The LPO is responsible for monitoring species, managing the terrain, and running educational activities connected to the reserve.

Can visitors explore the reserve?

Given its protected status and its importance for birds, especially during breeding and migration periods, access to the core of the reserve is restricted and governed by rules set by its managers. Sites like this are typically opened to visitors through marked trails, observation points, or guided outings organised by local tourism and nature bodies active on Oléron island and in the wider Rochefort Océan area.
