Le Marais, a wetland restoration Exchange. People visit the marais to enjoy new boardwalk and sculptures: entry arch announces "Ici Vivent les grenouilles". Stone and branch sculptures offer shelter to small animals escaping humans. Bird houses mitigate for trees cut to encourage the wetland, floating island in small pool gives frogs a place to sing and attract mates and for dragonflies to metamorphosize into adult form. For Marais visit to village, a sample of water, soil and plants will come for the vernissage, and a video will bring the frog concert to Les Arques.
