Identifying opportunities for invasive species management: an empirical study of stakeholder perceptions and interest in invasive species

Abstract

AbstractInvasive species are one of the main reasons for the decline in global biodiversity. When it comes to the management of invasive species, stakeholders who are directly involved with this issue play a particularly important role, as they are directly engaged in management and can also influence the public’s perception. This study therefore investigates how different stakeholder groups in Germany perceive invasive species. In total, more than 2200 people were surveyed, belonging to nine different stakeholder groups that are in contact with invasive species (hunters and members in hunting associations, farmers, members of environmental and conservation organizations, members in allotment garden clubs, animal welfare supporters, divers, employees in zoological gardens, administrative employees in the regulatory authority, speleologists). It was found that the number of invasive animal and plant species in Germany was roughly correctly estimated in all groups, but the economic damage caused by invasive species was substantially underestimated. When invasive species were mentioned, mainly conspicuous mammals or plants were listed (e.g. Procyon lotor or Impatiens glandulifera). In all surveyed groups, there was a notable level of interest in invasive species, and they were commonly regarded as environmental issues. While these results offer valuable insights into stakeholders’ perspectives on invasive species, they also highlight the need for improvement. In particular, there is a need for greater education of stakeholders about inconspicuous invasive species, the spread of invasive species and the damage caused by them.
