[Elektronische Daten] [Thomas Kaiser, Karin Pirhofer-Walzl] Background and Aims: Numerous studies noted that the seed banks of drained former wet-meadows did not have enough residual seed potential for the successful restoration of species-rich fen-meadows. However, it is unclear whether a decline in groundwater level exerts a negative effect on the seed survival of wet-meadow plant species in the soil. This paper assessed the dependence of soil seed survival on different groundwater levels. Methods: We tested the influence of the groundwater level on the seed survival rate of 8 wet-meadow plant species in fen lysimeters with constant groundwater levels of 5, 30 and 70cm. Seeds were buried in nylon mesh bags at 2 depths (5 and 25cm), exhumed after 1, 3 and 5years in the spring and tested in a climate chamber for germinable seeds under conditions of different day-night rhythms and fluctuating temperatures. Results: At both burial depths, more viable seeds survived at lower groundwater levels compared with groundwater levels near the surface. Waterlogged conditions resulted in a significant reduction in the number of germinable seeds for most of the studied plant species. A cluster analysis divided the eight plant species into three groups which differed in soil seed bank persistence and tolerance towards soil wetness. Conclusions: The decline of the groundwater level due to fen-meadow drainage does not negatively affect the seeds of wet-meadow plant species. Our results also suggest that for some species, the classification of soil seed bank type may vary according to the groundwater level dynamic of the location.
