The issue of redress anthropogenic interference with the landscape is one of the discussed topics today not only in professional groups but also among the public, because mineral mining takes place in many places in the Czech Republic. More and more are beginning to promote nearnatural methods of renewal at the expense of recently prevalent technical reclamation. Except for question, how the exhausted places reuse or renew also researches, how the whole process has an impact on the local fauna and flora.
The aim of this thesis was a qualitative comparison of water beetles among the forefield Bílina Mine and reclamation dumps Radovesice and Pokrok in North Bohemia province. It was evaluated 16 reservoirs in forefield and 15 reservois of dumps. A total of 36 taxa were found from which 19 were determined only at the species level. The most of taxa were located at post R9 in the forefield, at 4 locations there were none of them. The most abundant was genus Haliplus.
The collection took place using standard hydrobiological sampling by sieve. The material was preserved in alcohol, then separated, prepared and finally determined. The obtained data were evaluated and compared using the Jaccards index of similarity.
It was tested hypothesis: Due to the good dispersion ability of water beetle is representation of species in the forefield the same as constitution of species in the newly ponds at reclamations. Calculation Jaccard index between locations of forefield and dump reached the highest value of similarity 66,7 %, but over of the value 50% moved only in 7 cases out of 465 possible combinations, thereby hypothesis was disproved.
Found species were also evaluated from point of view conservation status according to the Red list of threatened species in the Czech Republic. This way was detected only one species, Laccophilus poecilus, falling into the category VU vulnerable. The determination must be examined.
