Flora and vegetation of a copper mine heap in Richtárová (The Starohorské Vrchy Mts., Slovakia)

The paper presents the results of floristic and phytosociological research conducted during growing season 2011 on a copper mine heap Richtárová, near the village Staré Hory situated in buffer zone of the Low Tatras National Park. In total, we found 147 taxa of vascular plants. The dominant plant species of the mine heap is Agrostis capillaris, which sometimes forms relatively continuous cover, and other species growing in small islands of plants tolerant to specific environmental conditions, especially Silene dioica, Acetosella vulgaris, Arabidopsis arenosa. We sampled 8 phytosociological relevés. Localities of relevés were selected considering variability of plant communities on the all mine heap.
