Impact of secondary landscape structure on the presence of non-native plant species in the cadastral area of the topol'čany town

Abstract

This study characterises an impact of secondary landscape structure on the introduction of non-native plant species during the years 2008 and 2010-2012. The field mapping was realised in the cadastral area of the Topo?čany town. The area of study consists of built-up area with surrounding agricultural land. During the period of our research, we identified the presence of total 55 non-native plant species, including 21 invasive, 11 casual and 23 naturalised. The highest dominance occurred in elements of ruderal vegetation without trees (22) and in the vegetation protection of aquatic dams (15). Several species were observed in a wide range of landscape elements. The occurrence in many structurally different types of habitats confirmed the ability of non-native species to tolerate a wide range of biotic and abiotic conditions.
