The study of macroscopic charcoal particles from peat bogs has led to a better understanding climate, vegetation and fire history, human impacts. To determine the relationship between activities role events in change during last 3300 cal yr BP, we present results multi-proxy approach based on analysis sediment characteristics, sedimentary charcoal, organic matter pollen, as well historical sources. This research permits high resolution palaeoenvironmental history reconstruction mountain area located southern central Pyrenees (Spain). In Pyrenees, is typically attributed since beginning Bronze Age may be correlated with slash-and-burn cultivation, metallurgy pasturing activities. data indicate good linkage signals Poaceae Cerealia which reveals impact agro-pastoral practices. also shows two periods, 2900–2650 BP 1850–1550 for higher frequencies occurred, suggested by arboreal pollen (AP) concentrations, confirming need biomass sustain fires. From Middle Ages, it seems that occurred anthropogenic use fire, tool forest clearance means maintaining open spaces.
