Resumo(s)
In the field study of Mediterranean grasslands, two types were identified, which from the edaphic point of view are classified as subnitrophilic and nitrophilic. Subnitrophilic grasslands include communities dominated by Taeniatherum caput-medusae and to a lesser extent by species of the genus Medicago sp. The second group of nitrophilic grasslands includes two subgroups: (1) those with a high percentage of Hordeum leporinum, which together with subnitrophilic grasslands have a high value for cattle and horse breeding, and as carbon sinks due to the high absorption of CO2. To subgroup (2) belong the grasslands of the Spanish dehesas and Portuguese montados, very rich in Poa bulbosa, Trifolium subterraneum, Biserrula pelecinus, considered of interest by the habitats directive and national and regional governments. Grasslands belonging to the Poetea bulbosae class are of interest for sheep farming, but not as CO2 sinks because they have a lower biomass than the subnitrophilous and nitrophilous of the Sellarietea mediae class. Considering the jaw system of the three types of livestock and the structure of the different pastures, a close correlation should be established between the type of livestock and the type of pasture. All these aspects should be known by future managers, which will enable them to defend the conservation and use of Mediterranean pastures, hence the need to teach them in Universities and Research Centers.
