We also found a relationship between the field layer species composition and the four environmental variables.
The much higher coverage of calcicole moss species in plots of cluster 2 than in other parts of the fen may be due to the stable and near-surface calcium-rich waters (as reflected by high EC values) and to the relatively low coverage of the field layer.
