Plant species diversity associated with invasive Reynoutria taxa in riparian vegetation : [streszczenie]

Abstract

Invasive plant species influence the resident species, communities and ecosystems in many ways. They may reduce species richness and abundance of native biota and decrease their local species diversity, although individual habitats vary considerably in their susceptibility to invasion. Riparian habitats are especially valuable ecological communities with high species richness and are identified as habitats with value for nature conservation. These particular habitats, together with other waterside habitats, are the most endangered and most easily invaded by alien invasive plants. In many riparian habitats, the Reynoutria taxa individuals are common invaders (Fragment tekstu).
