Characteristics of species of the vascular flora on the liquidated "Jan Kanty" coal-mine in Jaworzno (USID) area

The present paper has floristical-ecological character. It contains the alphabetical index of 294 species of vascular flora overgrowing the post-mine sites of "Jan Kanty" coal-mine in Jaworzno. The studies conducted in the years 2004-2006 included the occurrence rate of particular species of plants. Their specific autoecological properties with reference to their requirements for light, moisture and trophy of soil were also indicated (K. Zarzycki and others, 2002). The belonging of particular species to biocenological groups was determined (W. Szafer and others, 1976) as well as the character of plant life forms was described by Raunkiaer (1905) after L. Rutkowski (1998). The analysis of the selected specific species groups in vascular flora occurring in the investigated areas allowed to indicate that: hemicryptophytes and terophytes form the largest groups, ruderal and segetal species are visibly dominant while native synanthropic species (apophytes) predominate. Plants with full light requirements and mezotrophic species (moderately rich soils) are also very numerous. Mesophilous and hygrophilous species form a clearly dominant group. The analysis of floral species spontaneously entering the post-mine sites provides a range of applicable data concerning, e.g. the selection of species which can serve for biological reclamation.
