Opis:: Studies considering hummocks and hollows structure of bog forests were carried out in the Stare Biele Reserve in the Knyszyn Forest. The aim of the study was better recognition of bog forests spatial structure including recognition of soil chemical composition of hummocks and hollows. The bog forest communities in Stare Biele Reserve have various percentage of hummocks. The hummocks have similar morphological structure and are distinctly separated from hollows in all four bog forest communities. Degree of hummocks development and their morphological structure have big impact on plant distribution on their surface. Soil chemical properties are one of the factors, which influence floral abundance and composition of microcenoses. Soil reaction and calcium content, among other measured properties, exert the biggest influence on the floral abundance and composition of microcenoses.

Opis:: Studies on the soils in forest ecosystems in breaks of the rivers Jeleń and Sopot were carried out in the years 1997-1998. Although the rivers differ in length, catchment area, amount of water carried and breadth of the valleys, the most important factors affecting soil formation and their spatial differentiation are similar: bedrock, relief, water drainage, natural type of water management, position of the ground water-table relative to the river water level, and chemistry of spring and soil waters. Steep slopes of the valleys covered with poor and highly acidic podzolic soils are usually overgrown with fir and pine phytocenoses, or rarely, with mixed oak-pine forests. The bottoms are often characterised by longitudinal duality of the flood-plain benches. In the drier area close to the river beds under ash-alder forests, there are more fertile gley soils and gley podzols. Poorer and more acidic localities are occupied by mixed forests with spruce. In permanently moist fragments of the benches at the foot of the slopes and in depressions with stagnant water weakly acidic peat-mud and peat soils occur overgrown with bog-alder forests. Peculiarities of these areas are low peat-bogs suspended even up to 4-6 m above the water-table of the river.
