Summary
The paper focuses on the current state of the Šepeta mire vegetation complexes and changes it has undergone compared to the 1940 survey data reported in the monograph. Changes in the Šepeta mire vegetation were evaluated using the descriptions of plant communities and the vegetation map authored by K. Brundza as reference points. Based on these historical sources, plant communities of the mire were grouped according to its acidity zones as follows: meso-acidic, acidic) and the hyper-acidic one, which, being the largest, included plant communities of bog margins and slopes, quaking areas with numerous pools and complexes of hollows and flarks. As a result of the peat mining carried out in the Šepeta peatland, almost all vegetation complexes typical of the hyper-acidic zone have been destroyed. The relatively natural bog, still extant amidst the exploited peat fields, has undergone extensive changes: it is getting overgrown with pine trees, its former areas pools has shrunk. Although not destroyed by peat mining directly, mire margin communities of plants have also changed significantly. Almost everywhere, the former diversity of mire plant communities has been replaced by pine forests with Rhododendron tomentosum.
Key words: bog slope, bog pools, flarks, hollows, quaking bog.
