Invazní rostliny ve fytocenózách Ostravy (městské části Hrušov, Heřmanice) - rizika a možnosti managementu

Abstract

The bachelor work discourses about the problems of invasive plant species. The invasive botanical species belong in continuity with rising trend of number of suitable sites for their population among very frequent factors with harmful impacts from the point of view of the structure of various ecosystems. The increasing incidence of noxious effects that are caused with unlimited development of population of invasive species is fortified especially with unsuitable activity of human society that tends to creation of optimum sites for these species in the form of brownfields. The brownfields are areas which are not brought under cultivation. And that’s why we should devote the proper attention to this problems and we shouldn’t let a free way of activity to these plant invadors.
