The main aim of the study was to determine changes in the species composition and structure of natural tree stands in the Białowieża Forest (BF), which occurred in the years 1975&ndash;2012, as well as to evaluate their trends, directions and rate. The study was carried out on 121 permanent research plots (50 &times; 50 m), which represented the most important forest phytocenoses in BF, i.e. fresh pine-whortleberry forest <em>Vaccinio vitisidaeae-Pinetum</em> Sokoł. 1980, fresh mixed spruce-reed grass forest <em>Calamagrostio-Piceetum</em> Sokoł. 1968, oligotrophic form of hornbeam - bastard b

Abstract:
The Tomczyce nature reserve is characterized by a degenerated forest vegetation. We assume that the regeneration process was possible to launch after the establishment of the nature reserve in 1968. The vegetation of the Tomczyce forest complex was characterized for the first time by Jakubowska-Gabara (1976) whose studies were taken as a basis of our research. The phytocenoses after 40. years of protection have a greater participation of species with higher trophic and moisture requirements. The regeneration process in communities with pine trees is caused by an expansion of broad-leaved trees

The gaps were circular and of one tree height in diameter. During SWC, there were two harvesting occasions, on each of which 30% of the standing volume was removed.

AbstractThe vegetational and climatic developments during the Riss-Würm interglacial in the area on the northern flank of the Alps are reviewed. Reforestation seems to have begun over the whole region with a dwarf-shrub and ensuing shrub phase, leading to birch and/or pine woodland. The rise in summer temperatures, which δ180 values suggest to have been a two-stage event, permitted the immigration and expansion of more demanding trees (elm, oak, lime, ash, ivy, hazel, yew, etc.). Following the thermal maximum, which took place during the hazel and yew biozones, hornbeam dominated the forests i

The causes of small balsam's success in colonisation of new habitats are not known.
