Hodnocení výskytu Helianthus tuberosus v nivě řeky Ondřejnice

Abstract

At the begining of my thesis, I concentrated on characteristics of the selected area. This is the CHKO Poodří and district of Frýdek-Místek, where the river Ondřejnice flows through. Next chapter describes the different natural conditions of the selected area. Another part of this thesis is devoted to the invasion of alien species, with focusing on the one species, this is (Helianthus tuberosus). The main chapter of this thesis is focused on mapping and evaluation (Helianthus tuberosus), followed by proposals for measures against the future, unacceptable damage to natural communities.
