The soil characteristics of six communities with pastoral interest in León mountain (Spain) and the Ca, Cu, Fe, Mg, N, K and Na contents of soils and vegetation were analysed in relation with the nutritional characteristics of herbivores' diet. The communities were named after the most representative species: Nardus stricta, Bromus erectus. Genista florida. Erica australis. Genista occidentalis and Calluna vulgaris. Soils showed in general good conditions for vegetal growth. There were no relationships between soil and plants mineral contents. Ca and Cu were deficient in some moments during the stay of the animals in the mountain. Mineral concentrations in vegetation communities varied seasonally due to maturity processes and physiological changes in plants, depending on the kind of plant and the microenvironment where they grew.
