Resumo
The results of the pedoanthracological study carried out in the ultramafic massif of Sierra Bermeja (southern Spain) are presented. From the fossil record of charcoal soil, it has been possible to establish the dominant forest species during the Holocene, as well as to propose the possible ecological dynamics and the cycles of fire that affected this mountainous massif of such unique environmental characteristics. Highlights the charcoal found of Abies sp. (presumably A. pinsapo) in upper zones where today the species is extinct. Also, chronologies obtained through radiocarbon dating point to the coexistence of Pinus pinaster and Abies sp. in some zones of the massif during certain temporal periods, forming mixed coniferous forests. Opposite the traditional phytosociological hypotheses, the absence of old charcoal from Quercus sp. confirms that the conifers have constituted over the last 10.000 years the climax vegetation on serpentine soils of S. Bermeja.
