Beside them the special species show the value of the association with their 23% presence. Summary The newly characterized plant associations in South-Transdanubia can be found in Landscape protection area of Zselic. In this loess area in the South orientated narrow (20-25 m) valleys on black meadow-soils developed a forest-fringes association formed by tall and low forbs. There is no permanent water flow and even after heavy rain there is no water flow at its sites. Ten relevés were made in several valleys of the Zselic Hills between 23 September 1998 and 12 July 1999 both from the spring- and the late summer aspects with classical phytosociological methods according to the Zürich-Montpelleir school, using sampling plots of 10 x 10 m = 100 m2 size, the 6th is taken as holotype. The name of the association is Deschampsio caespitosae Inuletum helenii Dávid. Their dominant species in the tall layer of 1.5-2 m height is Inula helenium, in the low layer: Deschampsia caespitosa. Further constant species of the association are: Juncus effusus, Lycopus europaeus, Lysimachia nummularia and Mentha pulegium. Basically the cosmopolitan plants dominate (70%) but unfortunately adventive neophytes, e.g. Ambrosia artemisiifolia and Solidago gigantea may endanger the stability of the composition. The wet and hay-meadow species (Molinio-Arrhenatheretea) characterize the community. The high participation of natural competitors (70%) shows a good state of the association.
