Roślinność odłogowanych użytków rolnych w zlewni Czyrnianki (Beskid Niski) [Vegetation of barren agricultural areas in Czyrnianka basin (Beskid Niski Mts)]

Abstract

The investigations of meadow and pasture fallows in Czyrnianka catchment area, during vegetative season of year 2002, were carried out. The purposes of these investigations were qualifications of plant communities, characterisation of their habitat conditions and making habitats for constant protection. 53 phytosociological relevés by classic Braun-Blanquet method were performed and taken under numerical classification. As a result of classification the types of Gladiolo-Agrostietum and Epilo bio-Juncetum associations and Cirsium arvense-Agropyron repens community were originated. For characterisation of habitat conditions the indicator values by Ellenberg were used. The Detrendent Correspondence Analysis showed that moisture was responsible for differentiation of community composition. A dry variant Gladiolo-Agrostetum association, which contains species characteristic for xerothermical grasslands, is the most interesting from botanical point of view. This community is also protection worth.
