The aim of the study was to evaluate the species composition in the fallow lands in areas heavily degraded by the mining and processing industries. The research was conducted in the western part of the Małopolska province in the municipality of Trzebinia. The layer C of phytocenosis that is the green layer was analyzed by specifying its all plant species and by approximately estimating vegetation cover according to the modified Braun-Blanquet scale. 212 species of vascular plants were found in the research areas. Species typical of fallow lands and ruderal areas i.e. giant goldenrod, couch grass and bush grass are the dominant species in the study areas. Among the species found in the study areas the species typical of fresh meadows such as false oat-grass, goosegrass and sorrel as well as thermophilic species such as crownvetch, greater knapweed or cypress spurge appear with great frequency.
