The willow Salix caprea is a common colonizer of post-mining sites including those in the Sokolov coal mining district where this study was conducted. In one bioassay and two pot experiments, we investigated the effect of S. caprea litter on three plant species (Arrhenatherum elatius, Plantago lanceolata, and Lotus corniculatus) that commonly grow in late successional stages on these sites. In a sandy soil, leachate from fresh S. caprea litter reduced the number of germinated individuals (experiment 1) and shoot and root growth (experiment 2). In the clayey substrate originally unaffected by the S. caprea (experiment 3) leachate suppressed germination of all three species, but no reduction of biomass was observed. Biomass was enhanced, however, in substrate that was naturally enriched with S. caprea litter. Salix caprea therefore can suppress the establishment of new plants that arrive as seeds, but this suppression may only occur with seeds that directly contact the litter.
