Abstract: This paper proposes two predictive models, created with GIS technology and developed to evaluate the evolution and spatial distribution of arboreal vegetation during the Final Pleistocene – Early Holocene transition. Weighted values and logistic regression methods have been used, based on the ecological preferences of the tree species identiied in certain pollen diagrams from the Cantabrian region. Using GIS, zones in the study area that it with these ecological preferences and to thereby model the areas where speciic vegetation types would have been more likely to develop were marked out for both the Younger Dryas and the Early Holocene periods.
