Réserve naturelle nationale des marais de Bruges, National nature reserve in Gironde, France

The Réserve naturelle nationale des marais de Bruges is a protected natural area northeast of Bordeaux with meadows, streams, and wetland zones. The site comprises open grassland bordered by hedgerows and numerous small water bodies that create diverse habitats.

The protected area was established in 1983 to preserve a portion of the formerly extensive marshlands of Bruges. These wetlands were once far larger but became drastically reduced through human activity.

The marsh is grazed by two threatened regional breeds, Aure-et-Saint-Girons cattle and Landais ponies, which the manager SEPANSO uses to keep the wet meadows open. The name "jalles" is the Médoc term for the small watercourses threading the reserve; drainage channels are called crastes.

Part of the reserve is open to the public, with observation points set along the visiting path for watching the species that use the marshes. The ground is wet meadow and bocage, so plan for damp, uneven footing. The reserve is managed by SEPANSO with a team of four staff.

Despite its proximity to a major city, the site harbors rare species like European minks that have vanished elsewhere. These wetlands provide refuge for these endangered animals amid urban development.
