Ricerche pedologiche, floristiche e fenologiche sui pascoli del bacino del Rio S'Acqua Callenti (Villasalto, Sardegna sud-orientale)

The authors report about some studies relating to the plant-soil relations carried out in the Rio S'Acqua Callenti basin in the Commune of Villasalto (Cagliari). The soil and the vegetation in areas continually exposed to fires, in various expositions and altitudes, have been studied. The results confirm the negative effect of fires on the stability of the soil on the slopes and on reconstitution of the flora and the vegetation.
