Vegetation of the Csömöri-tó As a result of the processes mentioned above the vegetation of the Csömöri-tó is in a transitional phase. An incomplete version of the original vegetation has developed. High abundance of Typha angustifolia and Lastrea thelypteris is characteristic. Former open areas (quadrat 34 in Table 5) have been inhabited by one or another species of the immediate neighbourhood. The place of the former Sphagnum island is only indicated by the difference of vegetation and by the still present cindery torso of shrubs. Rare mosses (Sphagnum spp., Thuidium lanatum) and Epipactis palustris have disappeared from this area. In spite of these losses, this part is still the relatively most species rich part of the Csömöri-tó. A few species (Phragmites australis, and more considerably Lastrea thelypteris) have increased. Sphagnum spp. have been replaced by the more drought tolerant moss, Amhlystegium riparium (quadrats 35, 36 in Table 5). The northern part of the lake is covered by tall Typha angustifolia stands (quadrat 37 in Table 5) with tall sedge tuft (quadrat 38 in Table 5.
