Agriculture with High Natural Value (HNV) is a new concept, develped in the last two decades to describe those agricultural systems in Europa owing the widest biodiversity. Its main characteristics are the low intensity and the presence of semi-natural vegetation. Romania has one of the most important resource of areas classified as HNV due to the great variety of species associated to agricultural land utilised as permanent meadows, by traditional mowing and grazing activities. The aim of this paper is to present the results of research carried out to evaluate the biodiversity of microbial communities in three soils under traditional management of HNV pastures (Vicovu de Jos, Comănești) and natural meadow (Valea Moldovei), Suceava county. The total counts and species of bacteria and fungi (estimated by dilution plate), soil respiration (by substrate-induced respiration method), diversity index of Shannon (H) and similarity index between habitats were calculated and presented as Venn diagram. Biodiversity of microbial communities consists in 6 to 9 species with important roles in main processes in plant rhizosphere, soil organic matter recycling, cellulose decomposition, soil aggregation, biocontrol.
