Abstract: 

The application of a new clustering technique, named "distance-ranked sorting assembling" (DRSA), for the classification of plant communities is considered. Aspects of the stability of a phytocoenotic classification are analyzed. It is shown that a researcher can vary the scale of clustering and thus change the number of phytocoenons, classify reasonably the data of a wide environmental amplitude, and determine objectively ecotonic releves among the data. We suggest to use the quantity of faithful species per phytocoenon for qualifying clusters in the field of geobotany.

Keywords: cluster analysis, DRSA, phytocoenology, vegetation classification
