The aim of the study that was carried out during 1999 and 2000 was to find out whether the soil seed bank might play a significant role in the maintenance of valuable components of xerothermic grassland. Plant community searched is situated on the calcareous hill called The White Mountain (Central Roztocze Region, SE Poland). This area is protected as the ecological unit, the form of environment protection defined in Polish Nature Conservation Act. The main conclusion of the work done is the statement that the possibility of use of the seed bank to maintenance and community recovery is narrowed by some factors. The most important of them arc: great occurrence of seeds of species alien to xerothermic grassland and the lack of the persistent seed bank of main valuable components of searched community.
