Invasive Plants

The List of Invasive Alien Species of Union concern (EU Regulation 1143/2014) and national lists of invasive alien plants from each study country (see Project > Literature) formed the basis for the list of invasive alien plants along roadsides. The species were checked for their occurrence and spread along roadsides. All information needed was gathered from the original source (i.e. the national lists), by an extensive literature search, floristic databases, and expert consultation.
