Process of self-regeneration of the post-harvested areas of peatbogs in the Orawa-Nowy Targ Basin

The presented paper is an edited version of the part of Ph.D. thesis of the same title and by the same author. The main aim of the research was to assess the state of peat formation process on post-harvested fields of the selected raised bogs in the Orawa – Nowy Targ Basin on the basis of the acrotelm layer self-regeneration. The results revealed that the peat formation process takes place on six from among eight investigated bogs and statistical analysis of the percentage coverage by three plant groups proved that there are significant differences between them. The attempt to determine the rate of organic mass increase on post-mined areas by means of dendrological method was undertaken. Survey results suggest that the rate of organic mass accumulation on the investigated areas is high and depends on local conditions.
