Cover: Short-term summer inundation with base-rich and nutrient-poor surface water is considered beneficial in the management of non-floating rich fens, as elucidated in Chapter 5. Martin Chytrý is acknowledged for permission to use his high quality images of Hamatocaulis vernicosus in this photomontage.
