Beautiful and wanted – how young people perceive invasive alien plant species and certain options of their management

Abstract

ABSTRACT The perception of eight invasive alien plant species (IAPS) by 311 children and young people (10–24 years old) and their choice of management options were investigated, either with or without prior information about the IAPS given. In the first questionnaire, photographs of the IAPS (four terrestrial herbs, one tree and three aquatic plants) were presented, but their invasive status was not revealed. Participants characterized each plant by five opposing attributes, e.g. unwanted – wanted. In a consecutive second questionnaire, half of the participants were informed about the invasive character of the plants, the other half not. Both groups then evaluated various management options. Plants with attractive flowers were considered most beautiful and wanted. Moreover, if participants perceived an IAPS as familiar, they considered it native. Participants with information about the IAPS were more likely to choose containment or eradication and were also more able to justify their management decisions in a considerate manner. Participants without information were more likely to choose no intervention, especially in case of flowering forbs. The findings indicate that even a brief information about IAPS might help young people to make informed decisions when dealing with invasive species.
