Abstract

The aim of the thesis is to study and evaluate the importance of quarry lakes after shale mining in the landscape of Nízký Jeseník. The work focuses on individual lakes, their appearance, physico-chemical parameters in the autumn, winter, spring and partly summer aspect of the landscape and the possibility of their use fauna, flora and humans.

The theoretical part deals with the meaning and functions of the landscape and water surfaces in it; shale mining, its consequences and possibilities of restoration of post-mining landscape and acquaints readers with model area and factors affecting the quality of stagnant waters.

The practical part is devoted to acquaintance with the area of the Nízký Jeseník and the individual natural conditions and the area of interest itself - Jakartovice; methodology of site evaluation, inventory of species of plants and animals and evaluation of the importance of quarry lakes. The key part of the practical part is the actual survey, which ran from November 2019 to June 2020; evaluation of selected sites according to selected criteria; measurement and evaluation of selected physico-chemical parameters; inventory of flora and fauna and evaluation of the overall status and importance of the sites.

The key finding based on the results of this work is the fact that selected quarry lakes are generally not a suitable refuge for animals, yet these lakes in the slate landscape are used by them. Quarry lakes also have a positive effect on increasing the biodiversity of the post-mining landscape of shale, the microclimate has again become a destination for tramp and scout expeditions, and in the future the localities could become a cultural-historical destination for tourists.
