ABSTRACT
The thematic area is situated in the surroundings of Dabuleni, in the Southern part of Oltenia, South-East in Dolj County, near Bechet bridge, in the Danube meadow, in an area with sandy soil called "The Oltenia Sahara". In the named area meadows and plains covered with sandy dunes can be encountered. The total surface of the sands in the Southern part of Oltenia is over 140,000 ha, being represented in stripes of different lengths along the Danube banks and on the left bank of the river Jiu. The biotic conditions on the sandy soils in Oltenia allow the existance of some special plant communities. The natural habitats present a specifical structure and house a varied fauna. In the sandy area of Dabuleni there are over 400 vascular species, from which some are rare, being included in the red lists. From the floral point of view, the sands from Oltenia, Dabuleni area are different from the sea sands. The herbal vegetal associations from this thematic area are classified as: meadow plant communities, rural pasture, desert areas in locust tree plantations, aquatic associations in the Danube meadow, ponds and surroundings. As far as the ligneous vegetation is concerned, the most important vegetal communities are Bromo sterilis-Robinietum (Pócs 1954) Soó 1964 [13]. The growth and development of spontaneus plants and those planted on the sandy soil present somthing specific to those ones, compared to other types of soil. These species are to be found in European Directories Natura 2000 and on the red lists in the whole country. Cataloguing these natural capital and establishing coherent management measures in this area which have already suffered huge transformations due to the eco-climat changes, will lead to a better management and preservation of the area.
