What is the importance of the seed bank in the maintenance of the restoration potential of a 60-year-old abandoned calcareous grassland overgrown by Pinus trees? Very few calcareous grassland species have persisted in the Pinus stand. Four years after clear-cutting, the stand was nearing restoration towards a calcareous grassland. Seed longevity in the soil was not the most explicative factor. Dispersal of propugules from adjacent sources was also important.
