%X The use of a high resolution pollen record incombination with geochemical data from sediments composedmainly of layers of charophytes alternating with layersof vegetal remains plus some detrital beds permits thereconstruction of the environmental evolution of the last3000 years in an inland wetland of the Mediterranean domain,thus introducing a new climatic dataset for the LateHolocene. Hydrological fluctuations, reflected in the relationshipbetween emerged and aquatic vegetation andinorganic and organic C and N changes, can be relatedto aridity or humid phases, while relations among arborealtaxa (Quercus and Pinus) and Artemisia are used as temperatureindicators. Five climatic periods have been identified:a Subatlantic Cold Period (<150 b.c.), cold and arid; theRomanWarm Period (150 b.c.–a.d. 270), warmer and wetter;the Dark Ages (a.d. 270–a.d. 950), colder and drier;the Medieval Warm Period (a.d. 950–a.d. 1400), warmerand wetter; and the Little Ice Age (>a.d. 1400) indicatedby a cooling and drying trend. Despite the lack of any directevidence of human action, there are some episodes relatedto deforestation during the Reconquista (Middle Ages) thatmask the real climatic signal.
