The percentage of non-dormant seed among living was 0.3% in autumn, it increased to 87.5% in spring, and decreased to 3.0% in summer. In autumn, there were on average 6719 seed/m2 in the seed bank; in spring there were on average 2044 living seed/m2. Majority of seed (95%) were concentrated in the upper 5 cm soil layer. Some seeds, however, are present in lower soil layers, which indicates a short-term persistent seed bank.
