Numerical syntaxonomy of the tall-forb and tall-grass communities in the Tatra Mountains

The tall-forb and tall-grass subalpine and alpine vegetation belonging to the Mulgedio-Aconitetea from the Tatra Mountains was subjected to reclassification with Complete Linkage Clustering. The communities are classified into 3 alliances: Adenostylion, Calamagrostion villosae and Trisetion fusci. It was concluded that the orders Adenostyletalia and Calamagrostietalia villosae should be fused into one unit. Synecological relations of the communities was clarified using a series of Detrended Correspondence Analyses.
