Description
Interdisciplinary study of this site (geography, archeology, geology, palynology) allowed landscape changes to be traced from the Neolithic Age to the present. A major problem was to account for the presence of a layer of alder trunks and branches dated between 3300 and 2920 BP within a much more recent peat layer dated from 1915 BP. This phenomenon, which can only be explained by a great variation in water level, is possibly indicative of the effects caused throughout the Anjou valley by the rise of the Flandrian sea. The relative rarity of human presence is attributable to the marshy and inhospitable nature of this region, which made relations between man and the environment difficult. Agriculture became increasingly important only during the Carolingian period.
