The aim of this study was to investigate the dynamic state of meadow species (Molinietalia, Arrhenatheretalia) of vascular plants in the area of Cedyński Landscape Park and determine the most important factors of the changes. The floristic data were drawn up on the basis of field studies carried out in 1998- 2003 and of source materials. Of 113 species of meadow plants found in the area of CLP 9.7% are extinct or lost while 26.5% are potentially threatened with extinction owing to a small number of stations. This concerns stenotopic species attached to a given type of habitat and to methods used in meadow cultivation. In the landscape of the Park the accessibility and common occurrence of open habitats of the type of roadsides, fallows, yards at homesteads and fences, land reclamation ditches and earth banks present the possibility of easy access for meadow species of fairly low ecological requirements. Some species of this group are equally frequently distributed in semi-natural, natural and anthropogenic habitats (26%), while the remaining ones (25%) are more frequent in transformed habitats. In respect to preferences for soil moisture the species occurring in fresh soils prevail.
