Resumen: Creeping savin (Junlperus sabina L.) confers a strong character to the pastures in the calcareous fíat highlands of the Iberian Mountain System. Communities of creeping savin were found in 24% of sites in a startified sampling. Each of these was analized as a function of its specific composition, taking into account edaphic, geomorphologic and climatic factors. Pastures with creeping savin are found in sites of extreme environmetal conditions with predominant degrated stony soils and where heaving has selected plants specialized in producing under these stresses. The pastures belong mainly to the subhumid type included in Al. Bromion, however according to soil stoniness and degradation and water holding capacity, a variation gradient can be found. A traditional use, based on transhumance, with heavy grazing pressure during summer, outstands among the factors contributing to the make up of today's landacapes. These pastures high quality rests on its richnes in perennial legumes of a hígh forage valué. Chaemephyte and hemicrophyte creeping typea have special importance in pastures structures.
