Extensive livestock farming has been and continues to be the primary economic activity in Somiedo. Seasonal transhumance is one of the most prominent features of the livestock farming model, reflected in the unique landscape of Somiedo with 'brañas' that allowed seasonal use of high-altitude pastures, as well as in its distinct ethnographic expressions, such as the 'cabanas de teito' with their thatched broom roofs, which serve as an example of sustainable resource utilization.
