The study of soil mites (Acari: Gamasida; Oribatida) was done in three parks in Bucharest city, Cişmigiu, Unirea and Izvor, achieved by transects situated in the lateral sides (near the roads, boulevards or street), or in the middle of these areas. From 72 identified species of mites, 54 were saprophages-detritophages (Oribatida) and 18 predators (Gamasida). In all the parks 22 common species were identified: 14 oribatids and 8 predators. Spearman rank correlations applied between the number of individuals of the species from each park showed an appropriate concordance (rank correlation = r’) between them in Cişmigiu and Unirea parks (r’ = 0.30; r’ = 0.12), Cişmigiu and Izvor parks (r’ = 0.68), in Unirea and Izvor (r’ = 0.19; r’ = 0.05) and a non concordance between those from Cişmigiu and Izvor parks (r’ = - 0.21). Taking into account the correlations among the common decomposer species of the transects from the parks, an appropriate concordance in transects of Cişmigiu and Unirea parks (from r’ = 0.32 for T1-T3, to r’ = 0.58 for T2-T3) and a non concordance in all transects from studied parks (from r’ = - 0.80 for T1-T2 to r’ = - 0.01 for T1-T3) have been recorded. The common predators species have recorded an appropriate concordance in Unirea (r’ = 0.12 for T1-T3) and in Izvor (from r’ = 0.12 for T1-T3, to r’ = 0.51 for T2-T3). The frequency of the common species from these studied parks, which realized multiple possibilities of concordance and fewer possibilities of non concordance, led to the assumption that the soil-vegetation complex of the studied parks have similar characteristics and exercise a positive influence on the presence of the populations of these mites.
