Stan obecny i kierunki zmian roślinności nieleśnej Kampinowskiego Parku Narodowego [Current stale and directions of change of non-forest vegetation of the Kampinos National Park]

Abstract

Non-forest communities in the western part of the Kampinos National Park were studied in the years 1991 – 1998 with regard to their phytosociological diversity and dynamic processes currently underway in them. A total of 323 phytosociological releves were prepared by the widely used method of Braun-Blanquet. These releves served as basis for identification of 31 associations and 7 meadow and sedge communities of undetermined level. 15 syntaxa were recorded in the Phragmitetea class, 18 syntaxa – in the Molinio-Arrhenatheretea class, 2 associations in the Scheuchzerio-Caricetea class, as well as 3 grassland associations from Koelerio glaucae-Corynephoretea canescentis and Nardo-Callunetea classes. In order to determine the character and direction of changes in phytocoenoses, 4 basic ecological processes have been distinguished – fluctuation, degeneration, regeneration and secondary succession. Within secondary succession, recreative, creative and anthropogenically forced secondary succession were distinguished.
