Hydrological and soil erosion control importance of non-productive habitats in coal post-mining landscape restoration
Korol, Daniel ; Hendrychová, Markéta (advisor) ; Kovář, Martin (referee)
The present thesis deals with the issue of a literature review of surface mining in Most and its surroundings. It focuses on changes in the area due to surface mining, and describes their remedy in several ways. Emphasis is on water treatment and other affected constituents in nature. It also deals with describing a detailed definition of the area and non-productive habitat. The following section contains a methodology for field measurement - infiltration attempt made by a single-cylinder, during which found the average hydraulic conductivity of forests, meadows, successions and ruderals. The experiment was conducted at the lignite quarry dumps Czechoslovak army, Ležáky and Vršany.

More effective approaches of brown coal post-mining restoration
Christov, Ivan ; Hendrychová, Markéta (advisor) ; Walmsley, Alena (referee)
The thesis is focused on evaluation of landscape restoration procedures. The land was heavily devastated by large-scale quarrying. Here are compared reclamation procedures used in the Czech Republic and abroad. Study area is the North Bohemian brown coal basin, which formed areas valuable for many endangered species of flora and fauna after the mining has ended. Surface coal mining method causes the extinction of villages, roads, railways, land and greenery. Our task now is to minimalize these effects as much as possible. To create a new landscape, with an emphasis on the environment. Reclamation helps us to do that.
Monitored location is Střimická dump, where the representation of non-productive habitat was evaluated and there was proposed new, more efficient version of reclamation. Mapping has found that the current state of the dump is 5,2 % representation of non-productive habitat. The proposed variant represents the addition of new elements and thus increase the proportion to 23,5 %, which corresponds with the current trend of post-mining landscape recovery.

Mapping of non-productive habitats in reclaimed post-mining landscape in Most and Chabařovice area
Ledvina, Vilém ; Hendrychová, Markéta (advisor) ; Martin, Martin (referee)
The objective of thesis is to identify and map a non-productive habitats on areas after coal mining. The first part describes the reasons and ways of reclamation in areas after surface mining. Current knowledge and requirements for landscape protection during reclamation are presented in a literature review, and it shows the importance of these habitats. The monitored location are mines, dumps and areas affected by mining in the area of the Most and Chabařovice in the Ústecký Region in Czech Republic. Mapping has been done using the orthophoto map and field survey. Based on information from mapping the current status and composition of non-productive habitats on the monitored locations have been evaluated. The results are presented in the summary tables for each type of reclamation in monitored location.
Following percentage representation of non-productive habitats in four locations has been found: location A (2.39%); location B (12.64%); location C (6.27%); location D (4.78%). The results show that the representation of these habitats is on low level compare to recommended representation resulting from current knowledge about nature conservation.
Based on the results of the mapping measures have been proposed for optimal percentage representation of these habitats. The main measures include the building of landscape vegetation on large fields and increasing area of forest arising spontaneously in forestry reclamations. It is also appropriate to create non-productive forest habitats in large forest areas with absence of treeless or small forest meadow. The map outputs and thesis findings can serve as data for the protection of nature and landscape in the monitored location. Work can also serve as information source about the issue of reclamation and priorities to protect the environment during their realization.
