umbrosa can be found in large numbers. The moss layer is well-developed. The principal constituents are Plagiomnium undulatum, Calliergonella cuspidata, Brachythecium rutabulum, Cratoneuron filicinum, Pellia endiviifolia. According to the W value distribution (Fig. 10) the water supply of this area is better than in the two other sites of Calamagrosti-Salicetum cinereae. The proportion of W=8, 9, 10 value species is higher, W=3 value species are absent in this stand and the proportion of W=4, 5 value species is lower. The NC value diagram (Fig. 10) shows a large number of native components. No weed species were found in this area. w Fig. 10.

The 10th, 11th and 12th quadrats were sampled in the ScirpoPhragmitetum (C) and the 6th, 7th, 8th and 9th relevés in the Caricetum Fig. 9.
