Abstract
Pollen data from three sequences (CH, PD and CbN) in the Gredos Range (Spanish Central System) have been presented. These data record the evolution of vegetation from the 7000 BP (Holocene). The most important results are summarized in the domain of the pine forest and the change in the local forest composition. Then, the forests of Betula and Corylus, developed until 3000 BP, are replaced by deciduous and evergreen Quercus. At this time and only in the sequence CH, presence of Cedrus and Fagus has been detected. From approximately 1000 BP, takes place an important decrease in arboreal taxa, mainly of Pinus associated with the expansion of Ericaceae and Poaceae, in response to an increase in both temperature and anthropogenic activities.
