Changes of vegetal cover in the Aragonese western Pyrenees are shown throughout the last 50 years. The evolution is characterized by a generalised revegetation process with an advance of shrubs and forests. The medium and low slopes show the most intense revegetation as a consequence of the agricultural abandonment and the decrease of the livestock pressure. Nevertheless, few vegetation changes are recorded in cultivated lands and the pastures located above timberline.
