Climatic Changes In The Spanish Central Zone During The Last 3000 B.P. Based On Pollinic Analysis

Palinological data coming from different deposits of peat of the Spanish Central zone are presented in order to determine the climatic impact on the vegetation development, along 400 km with W-E direction, in the most western area of the mediterranean region. Given the geographic characteristics of the study area, the data coming from mountain areas (in the “Sistema Central Espanol”) and “Meseta” (“Submeseta Sur”) are compared, in order to understand the different replies of the vegetation according to the altitude, latitude and orientation, against local and global changes. Besides due to the studied period of time, special mention about the human impact manifested in the zone will be effected.
