The archaeological research focusing on El Mirador Cave (Sierra de Atapuerca, Spain) has revealed a succession of occupation levels in a dung layers context that span from the early Neolithic to the middle Bronze Age. The robustness and coherence of the chronological dates of the sequence have contributed to framing the beginning of farming practices on the northern Plateau of the Iberian Peninsula. This study focuses on the palynological analysis of the sedimentary sequence, spanning from ca. 7970–7770 to ca. 3390–3070 cal. yr BP. The results have allowed us to identify a landscape of mixed forest with evergreen and deciduous oaks and pinewood. Despite the discontinuities in such sediments, some fluctuations between different categories of anthropogenic taxa can be observed throughout the sequence, illustrating greater or lesser pressure from livestock or agriculture. From the Neolithic to the Bronze Age, we documented a reduction in the tree cover because of increased human pressure typical of the Neolithisation process, while the relationship between environment and society changes.
