Entre Lacs et Tourbières : approche pluridisciplinaire de l’évolution des paysages et des zones humides de la Pénide à Espalem (Haute-Loire)

Abstract : In the course of an interdisciplinary research programme, we aim at reconstructing the landscape evolution of the Cézallier mountain range during the Protohistory. This paper presents the first results on the La Pénide Plateau (Espalem, Haute-Loire) where former lakes, a protohistoric fortified site and a necropolis are found. Based on a core extracted in the « Lac Long » fen and on archaeological surveys, we have highlighted the main local environmental changes since 8500 BC. According to our results, the « Lac Long » was a lake and evolved into a mire during the Neolithic period, before becoming again a shallow lake during the Final Bronze Age, circa 1200-1000 BC. Protohistoric people settled on this plateau and built burial mounts (tumulus) on the edge of the lakes. Then, the lakes and the wetlands of the La Pénide Plateau were extremely drained, especially during the XIXth century. These natural sites are protected nowadays due to their specific flora and fauna (Natura 2000) and record an outstanding historical heritage.
