Papp, Beáta: Phytocoenological survey along the Koloska stream (Balaton-felvidék region, Hungary)

Fig. 5. W- and NC value scatter diagrams of Glycerio-Sparganietum var. sparganietosum (H) Caricetum acutiformis ripariae This is one of the most frequent Magnocaricion communities occurring along slowly running streams or in shallow stagnant water. The Caricetum acutiformis ripariae (B) of Koloska stream is rather poor in species. Carex acutiformis and Carex riparia are the most important components. A few other species are present with lower abundance e.g. Equisetum fluviatile, Eupatorium cannabinum, Scrophularia umbrosa. The distribution of W values (Fig. 6) shows that the water supply is sufficient in this habitat type, as large proportion of high W value (W=8, 9, 10) species are present. In the NC value diagram (Fig. 6), high ratio of native components (E+K) can be observed. However, the proportion of the native disturbance tolerant species and weeds is also considerable, reaching almost 20% altogether. Fig. 6.
