According to the guideline VDI 3957 Part 18, the described method is suitable to estimate the atmospherical reactive nitrogen enrichment within an investigation area. The nitrogen values within the foliose lichen Parmelia sulcata show a high correlation with literature values and measuring values of the Hessen Regional Authorities for Enviroment and Geology, as well as the results of lichen mapping according to VDI-guideline 3957 Part 13 and the indicator values of ELLENBERG/WIRTH. Also the correlation investigation between the two lichens Parmelia sulcata and Physcia adscendens shows promising results, even if further research should be done.
