Abstract:
The European method for mapping lichen diversity (LDV) as an indicator of environmental stress/quality in the Czech Republic was evaluated to determine its applicability in this country. A modified Hawksworth & Rose qualitative scale for determining air pollution levels was used for comparative purposes. The study was undertaken in a partially forested and reasonably polluted region of the Bohemian Karst in central Bohemia during 2003. Measurements obtained by the LDV method yielded values in the range 18–65; measurements obtained by the modified Hawksworth & Rose method indicated zones 4–7, with a high correlation with the LDV results. The LDV method proved to be applicable in the region, but its implementation may be limited by the lack of suitable trees and specific landscape ecology.
