Postindustrial sites in the Czech republic
Decheťová, Kristína ; Hendrychová, Markéta (advisor) ; Martin, Martin (referee)
Mining destroys ecosystems and creates degraded lands all over the Czech Republic. After mining are post-industrial sites created, which are likely to be an irreplaceable area for endangered plant and animal species. In the Czech Republic exist a lot of places, which are affected by mining and energetic industries. For these kinds of sites, early successional stages are characteristic. By the times that are not destroyed by technical restoration, these sites are later beginning a refuge for competitively weak species. Although researches in our country are highlighting the restoration ecology for a few decades like a suitable and cheap way to recovery, technical restorations are not decreasing. In the Jihočeský and Ústecký regions focused on sites, on which the mining was finished. These sites are going under succession and they are potentially suitable sites for many endangered species. Furthermore, in this work are outlines about active extractions presented, which were by raw mining material statistically evaluated from the size and their interference to SPA point of view within Czech Republic.

Ecology and conservation of invertebrates at anthropogenic sites
TROPEK, Robert
This thesis deals with communities of arthropods (and partly also vascular plants) colonising diverse anthropogenic sites. It reveals a conservation potential of these sites and focus on ecological requirements of both whole communities and individual species generalising these findings for usage in restoration of these sites.

Vegetation succession in old fields at broad landscape scales
JÍROVÁ, Alena
This thesis is focused on succession in old fields in Central Europe. Repeated sampling, analysis of surrounding vegetation and soil measurements were conducted in the Bohemian Karst Landscape protected area. Samples from the Doupovské hory Mountains and the rest of the Czech Republic were added to discover basic principles of old field succession at the larger scale of landscapes.

The comparison of diversity on spontaneously re-vegetated and technically reclamed dumps from coal mining in the Most region
MÁLKOVÁ, Lucie
Sites left to spontaneous vegetation succession and those technically reclamed were studied and compared on dumps in the Most Region, NW Czech Republic. Data were sampled in summer 2008 and 2010. Species composition and species diversity were analyzed using phytosociological reléves arranged along 100m transects. Alfa- and beta-diversity were evaluated. There were significant differences between sites in alfadiversity. Beta-diversity was highest in the spontaneously re-vegetated sites. There were also differences in species composition among the studied sites. I consider using spontaneous succession as appropriate in restoration of land disturbed by brown coal mining. It is a good alternative to expensive technical reclamation.

The effect of landscape context on the restored meadows in the White Carpathians
ČERNÁ, Ivana
Methods suitable for restoration of dry grassland were reviewed. An index of isolation was calculated for each of 34 meadows in the White Carpathians, which were restored by sowing the regional seed mixtures in the course of the past ten years. The relationship between the isolation, the year of regrassing and the number of newly established target species by the spontaneous succesion was studied.
