The abundances of invasive plant species in the vegetation have negative impacts on the integrity, structure and function of autochthonous ecosystems. Invasive species act as stressors for plant communities and change their species compositions. In the Czech Republic, Ceratophyllum demersum is a species that may represent a risk of invasiveness, particularly in shallow types of water bodies. It is autochthonous is all continents, but it is primarily centred into warmer parts of the mild climate of the northern hem...

The study responds to the need for restoring the natural function of small streams and recovery thereof in terms of European Parliament and Council Water Framework Directive 2000/60/EC within brown coal mining areas damaged by anthropogenic impacts. The study observed: which environmental factors are the most relevant to the current state of these sites (the positive and negative effects), what types of recovery are typical of natural parts of the streams and significantly changed/affected ones, and the effect of ...

Sites that arise after mining in our country are mostly unique habitats and should be dealt adequately. This fact is valid in particular for smaller sites of mining and mineral extraction. However, the restoration should not rely just on spontaneous succession. If there in the area are developing or is there a prerequisite of development of plant communities with important species (refuge, hot spots), it is always necessary to support the development of desirable successional stages, and, vice versa eliminate inva...

The work is aimed at evaluating the effects of deep coal mining on the landscape in the Jest?ebпїЅ Mountains (Czech Republic), where coal had been mined for more than 400 years. Changes in the landscape are described, especially new dominant features that arose from coal mining. These are mainly spoil heaps that were either reclaimed or left for natural regeneration, but also other objects used for different purposes пїЅ brownfields. The impact of coal mining on the character of the landscape in the region is asse...

Experience of radiological contamination of land, especially after the Chernobyl and Fukushima disasters has shown the need to explore possible ways of capturing radionuclides in the area affected and adapting the landscape management to this purpose ex-ante the considered accident in terms of prevention. The project "Minimizing the impact of radiation contamination on land in the emergency zone of TemelпїЅn NPP" (2012-2015), dealt with the possibility of utilization of wetlands as retention sites for water carryi...

The abundance of invasive plant species in the riverbank vegetation negatively affects the integrity, structure and function of the natural ecosystems. Invasive plant species are stressors for plant communities and they change their species compositions. This leads to species deprivation and homogenised regional flora. The Czech legislation defines invasive organisms as harmful organisms that are allochthones for a locality, which having been introduced into the locality are able to negatively influence plants or ...
