Abstract
The work concerns the floristic transformations occurring on abandoned arable lands with self-growing grassy sward. The grown sward, initially with a large share of synanthropic dicotyledonous, had been transformed as a result of the land use. Animals, particularly grazed in the “non-stop” system, had a dominant impact on the change of floristic composition of sward. Treatments including mowing weeds as well as organic and mineral fertilization affected these changes as well. Floristic composition of sward had been also influenced by other orographic factors, especially the altitude above the sea level and slope exposure. The presented research results come from the Grajcarek stream catchment where the valley forms the border between the Little Pieniny and the band Radziejowa in Beskid Sądecki. This publication is an attempt to synthesize the results from the years 1960-2015 and concerns floristic and spatial changes including mainly transformations occurring within the grassy vegetation. The variability of the floristic composition is presented in tables and diagrams from selected years within the three altitude zones (1/ <680; 2/ 680-800; 3/ >800 m above the sea level) and two slope exposures (N – S). The changes are also described numerically using for this purpose the classification of meadow and pasture plants (Lwu) given by Filipek (1973).The analysis showed that, despite the diverse intensity of use and limited treatments, especially fertilizing, the state of grassy sward quality had been gradually improved. In the analyzed continuity of time the increased share of valuable plants Poaceae was registered in the all altitude zones. At the same time the share of low-valuable Poaceae and dicotyledonous decreased. As a result, the total Lwu of grassy biomass increased, while bigger and more advantageous diversity was registered on the northern exposures than on the S-exposures.
