    The description of the forest phytocenoses was based on 69 phytosociological records taken in the areas of coniferous habitats and forest habitats. They were taken deep in the forest situated about 80 to 100 m from the car park (typical forest communities) and in the area of 1 to 10 m in width, adjacent to the car park (ecotone zone). The phytosociological records were also taken in the area of mid forest car parks. The aim of the studies is to determine types of communities and their structure (floristic composition, phytosociological stability (S) and cover coefficients (D) of species). Deep in the forest, in coniferous habitats (mainly in the mixed fresh forest) dominant are the patches of Leucobyro-Pinetum association, of Pomeranian-Silesian variety with a distinguishing taxon Deschampsia flexuosa. In the habitats of the mixed fresh forest the most numerous are the phytocenoses of the birch-oak forest (Betulo pendulae-Quercetum roboris), and as to the fresh forest, the most numerous is the community of fertile beech forest of Pomeranian type (Galio odorati-Fagetum). Communities within the ecotone zone are charecterised by partial rebuilding of the structure. The same communities as those in the ecotone zone are found deep in the forest, but there are more species of seminatural and synanthropic communities. Phytocenoses in car parks have a completely different structure. In the fresh coniferous habitats and in the mixed fresh coniferous habitats, patches of Sieglingio-Agrostietum alliance are observed, a part of which was classified as suballiance S.-A. poëtosum annuae. In fertile forest habitats, dominant are mainly patches of carpet community Lolio-Polygonetum arenastri, with a considerable contribution of the communities of Molinio-Arrhenatheretea, Artemisietea and Stellarietea mediae classes. It was also observed that the forest communities within the forest habitats are poorer floristically in comparison with phytocenoses of forest habitats. The richest floristically communities are the ones within the zone in which a car park is adjacent to the forest.
