Sheep tend the salt marshes on the Guérande Peninsula

Guérande – 30 July 2026: Where machinery can barely make progress, a flock of sheep takes over landscape management. Young shepherd Léa lets her animals graze in the salt marshes on the Guérande Peninsula. There, they eat grasses and other plants spreading along edges, on embankments and in unused areas. A report on France 2’s midday news presents the grazing as an important contribution to preserving the salt-marsh landscape.

The salt marshes are a cultural landscape shaped over centuries. A finely coordinated system of basins, embankments and waterways channels seawater through the facilities until the salt can be harvested. If vegetation spreads too extensively, paths and installations become less accessible; the landscape’s open structure also changes. On suitable areas, the sheep therefore replace part of the mechanical maintenance work.

Léa’s flock thus fulfills a role that extends far beyond ordinary livestock farming. The animals keep transition zones between salt basins and adjacent areas open. At the same time, they can reach sections where the use of heavy equipment would be difficult or undesirable. According to the television report, their work has now become an established part of maintenance.

The salt marshes extend across several municipalities on the Atlantic coast of the Loire-Atlantique department, including Guérande, La Turballe and Batz-sur-Mer. The Cap Atlantique intermunicipal authority distinguishes between the Guérande basin and the Mès basin farther north. Both areas shape the peninsula and are closely linked to traditional salt production.

However, grazing is subject to special conditions. Salinity, fluctuating water levels and narrow paths require management adapted to each individual section. Where and when the flock can graze must therefore be guided by the requirements of salt production and nature conservation. The animals are part of the management system, without the production areas becoming ordinary pastureland.

The ecologically sensitive area is partly part of the European Natura 2000 protected-area network. At the same time, a large portion of the salt marshes consists of private and working land. Local organizations therefore ask visitors to observe paths and access rules. Salt production, landscape management and species conservation come together here in a confined space.

The flock mainly keeps clear those areas that can easily be overlooked in day-to-day operations. In this way, Léa’s work combines traditional grazing with a concrete task for salt producers: sheep tend embankments and marginal zones, while sea salt continues to be harvested in the neighboring basins.
