This article focuses on the analysis of plant remains (seeds/fruits, charcoal, pollen, spores, and non-pollen palynomorphs) from two archaeological sites (pre-Roman and Roman) located in Las Medulas, a cultural landscape, in the northwestern part of the Iberian Peninsula. The article explores the way the communities living in the area managed their environment and the impact of productive activities on the landscape. This research has shown the multiplicity of needs this landscape satisfied and the various ways these communities managed the surrounding environment through different productive activities (agriculture, animal husbandry, and mining amongst others).
