【 摘 要 】

This article deals with the possibilities of population management of invasive and in Czech Republic no - native species Helianthus tuberosus. We have chosen study areas in Poodri PLA, it is located near the industrial city Ostrava (Moravian-Silesian region). Invasive Helianthus tuberosus forms monodominant vegetation, excludes the original and often rare plant species and reduces biodiversity. It is a risk for the further development of the landscape of Poodri PLA. There is no known effective way to dispose of invasive Helianthus tuberosus so far. We have applied the proposed management works on 15 monitoring areas and then evaluated their effectiveness. We have used chemical (herbicides) and mechanical (mowing, digging up) methods and their combinations. The most effective was the combination of 3 interventions: manual mowing - spraying - mowing by mechanization, just mowing itself rather promotes the spread of the population. We can say this is a pilot study from a long-term project dealing with the effectiveness of different ways of invasive plants management.
