The palynological of two sedimentary organic sequences placed over the present sea level, one located in the southern atlantic coast and the other in the cantabric coast of Galicia (Spain), shows an important tree-like cover (Pinus sylvestris L. & Alnus Miller) in the preceding phase to the pre-Boreal period, more intense on the N. It brings into the pre-Boreal period, and it reappears with Quercus L. and Alnus Miller into the Atlantic period. Likewise, there are differences concerning vegetacional data windscreen the depot of the N and of the S: there is more tree-Iike outstanding presence of the Ulmus L. the marked manifestation of Corylus L. and ample and prolonged performance of the Ericaceae they are outstanding characteristics of the N depot. In the Atiantic period in the coast as log as the Asteraceae Cichorioideae increase in the southern Atlantic coast. We propose that the erosion of the soil have different risk intensity. Generally that is pussy in the Preboreal and major during the Holoceno, it is due at stage of forest degradation.
