The Lasné Salt Marshes
The Marais de Lasné, a former salt marsh dating from the Middle Ages, has been classified as a Sensitive Natural Area since 1978, thus preserving an exceptional natural and cultural heritage. With its 31 hectares, the site combines environmental protection and traditional activities, welcoming two oyster farmers and a salt worker to perpetuate its identity. In 2003, rehabilitation transformed the salt marsh into a place of discovery, interpretation, and refuge for many migratory birds.
Located in Saint-Armel, opposite the island of Tascon, the Marais de Lasné returned to activity in 2003 thanks to the arrival of salt worker Olivier Chenelle. In spring, the pied avocet, the white stilt, and the common tern return from Africa to nest. The dikes are freely accessible, offering privileged observation of wildlife, including shelduck, redshank, egret, and many others. Since 2010, the black-headed gull has nested on the site, posing a challenge to the survival of shorebird broods, these chicks being prey for this predatory gull. Black-headed gulls also joined the site in 2014.
The arm of the sea between the marsh and the island of Tascon welcomes in the fall, especially in October and November, as well as in winter, a wide variety of birds, notably brent geese accompanied by various ducks such as whistling birds. , pintails, nutsedges, and shelducks. Shorebirds, such as the dunlin, the silvery plover, and the great plover, are also present in numbers. Coots make irregular appearances, adding to the diversity of this unique ecosystem.
