Litovelské Pomoraví Protected Landscape Area (Czech Republic) was chosen as the study area of heavy metal pollution (Zn, Ni, Cu, Pb, Cd). Assessment of heavy metal concentration in the soil was performed at eleven sites along the water stream in the alluvial plain (Morava river) and compared with concentration in selected plant tissues. Heavy metal concentration in two plant species (Urtica dioica L., Taraxacum sp.) and soils were detected by atomic absorption spectrophotometry (AAS). The correlation between heavy-metal concentrations in plant tissues (roots, leaves, stems) and in soils was tested and the ability of plants for heavy-metals indication in the alluvial plain landscape ecosystem was observed. Differences in correlation and ability to accumulate heavy metals were found not only between species and heavy metals but also among various plant tissues. Taraxacum sp. As a whole closely followed concentration of Zn, Cu, Pb and Cd and seems to be much more suitable as bioindicator than Urtica dioica L. Nevertheless, there are plant parts of both species with better response to adequate metal. Some plant tissues of both species provide ambiguous results, which was discussed in terms of living forms, growth strategy and genotypic differences.
