The study examined the effect of variation in hydrology on seedling recruitment of shrubs, trees and herbs in peat bogs. The establishment of plants and hydrologic conditions were followed in two peatlands in the Polesie Zachodnie region, Eastern Poland. Meteorological conditions in the study sites ranged from very dry (2006) to very wet (2007) and strongly affected ground water level in the bogs. The emergence of woody species typical for advanced vegetation succession was higher in forest-bog, while the recruitment of typical peat bog plants was higher in open bog. Disturbance in the vegetation positively influencedemergence of typical peat bog species and Betula pubescens, but the effect was only foundin the dry year. Only in Pinus sylvestris did recruitment increase in wet seasons. The results suggested that an increase in the number of woody species in peat bogs may be enhanced during relatively wet seasons and that disturbance in the vegetation cover are not required for seedling recruitment of these plants.

A sample of Betula nana from the Linie reserve near Dąbrowa Chełmińska, have been fingerprinted using random amplified polymorphic DNA (RAPD). The high level of genetic variation was detected. All individuals had unique genotypes, supporting the generally high resolving power of RAPD’s. For the conservation strategy, information about the distribution of the genetic variation within and among populations plays very important role. Thus, extensive study in other populations of dwarf birch is needed.
