Abstract	The research was made in three central parks Cismigiu, Unirea and Izvor, in Bucharest city (in 2006 and 2007). The research of the edaphic mites (Ord. Gamasina; Ord Oribatida) was made by the transects method (T): the long side (T1), situated parallel with the boulevard; the short side (T2), situated parallel with street and the middle side (T3), situated in the center. From the total number of 106 identified mites species, 83 species were decomposers and 23 predators. Common species for all urban areas were 10 saprophagous-decomposers: Zygoribatulla terricola, Tectocepheus sarekensis, Epilohmannia cylindrical, Medioppia obsoleta, Dissorhina ornata, Ceratozetes mediocris, Oribatulla tibialis, Hermanniella dolosa, Eulohmannia ribagai, Trichoribates novus and 2 predators: Rhodacarellus silesiacus and Hypoaspis aculeifer. Differences appeared between the saprophagous-decomposers and predators mites populations from the urban areas on the taxonomical spectrum, on the structural and dynamics of parameters. The statistical analysis of the ecological parameters (x/m 2 ; Ar%; C%, D%) of mites populations showed an important representation of oribatids, as well as of gamasids. The saprophagous-decomposers recorded were: 53,200 individuals/sq.m., in Unirea park; 54,800 individuals/sq.m., in Izvor park, and 33,600 individuals/sq.m., in Cismigiu park. The predators recorded were: 8,200 individuals/sq.m., in Unirea park, 7,200 individuals/sq.m., in Izvor park, and 5,600 individuals/sq.m., in Cismigiu park. All these aspects were due to the bioedaphic conditions, which were not so favorable to the development of the both trophical categories in urban areas as parks. The differential researches of the mites populations from the natural ecosystems and parks can be a database in parks planning strategies.
