The present study demonstrates the classification of the riparian alder forests of the Alpokalja region through the analysis of their stan ds in the Sopron Hills. Besides the historical, ecological and floristic data collection, the diffe rentiation of these forests was examined using 36 coenological relevés recorded according to the B raun-Blanquet method. Cluster analysis, principal component analysis and TWINSPAN analysis were applied in the process; the definition of diagnostic species for the resulting units was c arried out by fidelity analysis using the Ф coefficient. The presence of three alder forest as sociations was verified by the research in the study area. In the vicinity of the lower and middle sections of the streams, characterized by stagnant water, small patches of swampy alder fores ts ( Angelico sylvestris – Alnetum glutinosae ) occur. In the fast-flowing stream sections alder wo ods rich in species of mesophilic deciduous forests ( Aegopodio – Alnetum glutinosae ) can be found, while along the middle and upper se ctions of the streams, at sites with seepage water, mixed ash-alder forests with montane herb species ( Carici remotae – Fraxinetum ) are typical. The investigations revealed that the Carex brizoides dominance-type alder groves were secondary forests that formed in former meadows and they belong to the 3 mentioned riparian alder forest typ es.
