Are invasive plants a problem in Europe? Controversial views among invasion biologists
Date:2/3/2014

ETH Zurich. Some of the study participants used a biological definition to discriminate native from non-native species ("species from a different biogeographic region"), while others referred to culture ("species not familiar to local people"). "Based on each definition, a different set of species is considered non-native in a particular country," Ms Humair said. Equally, different experts considered different impacts by invasive species on ecosystems and their functioning for humans (ecosystem services) to be relevant. "These ambiguous interpretations of key notions and divergent assessments of impacts may then lead to conflicting risk assessments and pronounced misunderstandings, eventually impeding concerted management action," concluded Ms Humair.

The authors propose that invasive species management would strongly profit from broader participation of different expert groups and stakeholders in invasive species research and management, making scientific uncertainties as well as diverging opinions towards management goals transparent.
