Mound and Marshes of Saint-Pierre-le-Chastel

This site brings together two very different entities: the dry environment on the hillock is characterised by the presence of broom and small areas of dry grasslands on basalt This area also offers a 360° view of the Sioule valley and the Chaîne des Puys. The lower, wet environment (the Paloux marsh or marsh of the Mazayes stream), temporarily flooded during the Sioule floods, plays a major hydrological role (natural filter, flood control, etc.). It has a mosaic of habitats linked to wetlands such as cariçaie, willow, jonçaie or megaphorbiaie.
