Industrial deposits: Are they habitats of threatened or invasive species?
 Vojtíšek, Pavel ; Tonika, Jaroslav (referee) ; Kovář, Pavel (advisor)
There was made many deposits of industrial slags on our landscape during second half of 20th century. Many of deposits were abandoned without recultivation because of missing or inadequate legislation. Often very extreme habitat enables scientific research. Deposits and their surface are developing and stabilizing because of primary succession. This study works with two types of deposits: ash-slag and ore-washery sedimentation basins. During succession many plant species are introduced onto basin plateau. Ecosystem contains many unoccupied habitats and for invasive plant species it's easy to introduce into these free habitats. Contrariwise the ecosystem should pose a refuge point for ecological important plant species. In this study are worked data about total vegetational cover of vascular plants on 21 sedimentation basis (12 ash-slag and 9 ore-washery). From the data package were sorted out plants demonstrably invasive, potentially invasive and endangered plants. An occurrence of the species was compared with the type and age of sedimentation basin. Key words: Sedimentation basin, invasive plant, potentially invasive plant, endangered plant, life strategy, management
