This dissertation applies its mind to the evaluation of five selected localities caused by slate mining in the area of the Low Jeseník, namely at point-blank range the Kružberk water reservoir and is based on the lichenological research and on the Czech Hydrometeorological Institute data. Two lacalities, 1 and 2 are located in the west side of the dam, the locality 3 is in the east side and the localities 4 and 5 are located to the south from the dam.
From 2015 to 2016, during the ongoing research, there were determined 23 the most commonly ocuring tereristic lichen species. To the found vulnerable species belong, for example, Cladonia glauca or Cladonia ciliata. In the locality 3 the most occuring family Cladoniceae is mainly represented by Cladonia ciliata, Cladonia rangiferina and Cladonia arbuscula.
Based on the results it was discovered that lichen species coming from the Cladoniceae family are the most frequently spread on the upper part of the localities, on the top of the slate slag heaps; but the slopes are prefered by sessile species. The slope posts are too extreme because of their enormous inclination and exposition. The tree storey was determined too together with frequency of woody plants incidence on the grounds of localities shielding. Full-grown trees expanded from the surrounding forest were especially found at the slag heap bases. Larix decidua was mostly observed, Betula pendula colonized slopes. On the bases of The Czech Hydrometeorological Institute data was the Kružberk dam area assessed relatively clear because it is the area protected against pollution and and is considered to be a fresh water resource. Air pollution made by NO2, SO2 and MP10 showed good results with low improving level from 2014 to 2015.
There is made a suggestion to have the minimal management because there was not seen any negative human or animal influence to the lichen diversity and natural evolution of association has been going on. Large frequency of Cladoniceae was monitored in the locality 3 and so this locality is suggested for long-term monitoring of environment with chemical-physical methods and monitoring lichen diversity.
The author developed her photo suplement and used here her own illustrations to easy determine the most common species occuring on the stone quarry. This appendix can be found at the end of the dissertation.
