From the geographical point of view, the Lower Basin of the Motru River lies in the western part of the Getic Piedmont, with the coordinates: 44055' north latitude and 23045' east longitude. The studied area covers 691 Km2. The physical-geographical position and the pedo-climatic particularities specific to the territory under research confer the vegetation a mosaic nature with a particular specificity, determined by the quite strong Balkan and sub-Mediterranean influences. With the territory under research located just on the line between the nemoral area (of the oak forests) and the floor of the hilly common oak (up to the sub-Carpathian Hills), we cannot talk about the presence of the acidophilus common oak forests, which is characteristic to the sub-Carpathian region. In this transition area, between the altitudes (200) 250 and 380 (402) m, we have identified mixed common oak forests, associated with Hungarian oak and Turkey oak, belonging to the association Potentillo micranthae-Quercetum dalechampii A.O.Horvát 1981 (Syn.: Potentillo micranthae-Quercetum (petraeae resp. dalechampii-cerris) A.O.Horvát (1956) 1959). The affiliation of these phytocoenoses to the above mentioned association is done according to its transition association nature, between the silvosteppe forests and the mesophyle, acidophilus forests in the sub-Carpathian area of Oltenia.
