Abstract
Presentamos los datos antracológicos de los niveles de ocupación de la Cueva de El Conde fechados entre 40-32 Ka. BP, procedentes del área de excavación denominada “Plataforma”. Pinus sylvestris, Sorbus aria, Betula, aparecen como principales táxones arbóreos. El estrato arbustivo presenta una gran variabilidad florística procedente tanto de substratos calcáreos: Arbutus, Rhamnus, Crataegus, Prunus como silíceos: Erica, Leguminosae (Ulex, Cytisus). La configuración topográfica de este territorio así como la variabilidad de substrato entre áreas geográficamente próximas, explicaría la proximidad de estas comunidades vegetales con afinidades ecológicas diversas. Asimismo la posición de la cueva a media ladera habría facilitado el aprovechamiento alternativo de todas ellas en lo referente a la gestión del combustible por parte de los grupos humanos que habitaron estacionalmente dicho yacimiento.
Anthracological data coming from the Cueva del Conde “Plataforma” excavation area, dated between 40-32 Kyr. BP, are presented in this work. Pinus sylvestris, Sorbus aria, Betula, appear as main arboreal taxa. Shrub stratum presents a great floristic variability coming from calcareous: Arbutus, Rhamnus, Crataegus, Prunus as well as siliceous substrats: Erica, Leguminosae (Ulex, Cytisus). Topographic characteristics of this area and discontinuity of substrats geographically closed, explain the proximity of these vegetal communities with diverse ecological affinities. Futhermore, the position of the cave in the middle part of the slope has made possible the alternative firewood management made among these vegetal communities by human groups that have seasonally inhabited this site.
