Human activities during the last millennium have shaped most of present-day landscapes. During this time, in southern central Pyrenees several climate periods and phases variable human disturbance driven varied landscape responses. In previous studies sediment deposits Lake Montcortès (southern Pyrenees) climatic shifts (including Medieval Climate Anomaly Little Ice Age), as well forest clearance by fire, agriculture cattle raising main impacts were recorded since times. work we use non-pollen palynomorphs (NPP) on same sequence to reconstruct different activities, with a special focus grazing, at an average resolution around 30 years per sample. Independent NPP proxies for fire found, supporting former studies. Moreover, record shows four high abundance coprophilous fungi: 1) 830–865 CE; 2) 1120–1290 3) 1530–1795 4) 1865–1880 CE. These correspond increased livestock farming, reported historical documents. Comparison pollen, documents, records show that impact dynamics been mostly related population density controlled historical, political cultural changes Pyrenean mountains. comparison independent highlighted strength indicator value obtained.
