The thesis is dealing with biomonitoring of terrestrial lichens occurring in lichen pine forests L8.1A in the Česká Lípa district in northern Bohemia. Altogether, 57 species of terrestrial lichens were recorded based on excerption of historical literature. Field survey managed to find 33 species of terrestrial lichens. We succeed to find six new species for the area of study. Within the categories of endangerment of species have occurred primarily common species (LC), as well as nearly threatened (NT), but also vulnerable species (Cladonia cervicornis, C. ciliata, C. glauca, C. macrophylla, and C. strepsilis). Two species of endangered lichens EN (Cladonia crispata and C. portentosa) were also found. Based on the biodiversity research in 27 plots and comparison of vegetation plots and abundance of species in every plot, diagnostic (Dg) and dominant (Dm) species were found. Using restricted analysis of the RDA the variability of data is the best explained with relation of species to individual sites. Altitude and pH appeared marginally significant. Using unlimited linear PCA analysis and comparative dendrogram was found, in which plots are most abundant species and the plots of similar species composition. The result of the revision of habitat mapping segments L8.1, subunit L8.1A is finding that many segments should be amended quality and maintained or should be allocated to another habitat. Of the 55 segments the only one segment was correctly evaluated. Based on the habitat mapping in terms of coverage E0 was discovered 8 emblematic sites subunit L8.1A.
